DG locost race car powered by SR20DET project

[Duncan Grier]

Well after a backlog of work and changing my mind (not like me ) https://www.rtoc.org/boards/showthrea...t=19511&page=2

It is almost time to start - will share some pics of the conversion for those interesed

Car is a locost race car which comes with all the nice track day bits fitted inc Spa digi dash and standalone management, full cage etc etc

I was never going to be happy with 165bhp even in 535kg and the quest started for the best route to upgrade based on not spending loads as it is a pure track car

After lots of measuring and costing of various options

VAG was working out too much as the 20V are in more demand now and holding good money and the tsi ECU not fully cracked etc and cant be bothered with the hassell or poss costs and still needed to resolve the gearbox option

Then there was the B204 saab and omega box which in fairness was almost a done deal and looked very good

Then it was keep it simple and sc the current zetec in the car but the box needed a lot of cash spending to cope and then

Ended up measuring a SR20DET setup from a 200sx S14 and even the ratios and diff look ok based on the smaller wheel / tyre combo

Know NOTHING about jap cars (not that that will stop me) but spoke to a few good friends (thanks for the pointers Adey ) who know them and seems a good little unit and hope to start in a few weekends

Doing some maths should be good for 500-600bhp per ton in stage 1 spec - got slicks for it to collect but expect a bit of a handfull lol

1st track day RTOC ND and Spa prov booked for later in the year

Hope to collect donor car this weekend - look out

Adam was selling a freshly forged SR20DET, for a bit of a bargain a little while back. It might be too good for one of those skateboard things though

Sure it would not the bargain I am thinking of - remember I have had training from Mart for many years now

Looking at the car in question tomorrow and hope to leave deposit and collect over weekend - Adam be quick if you have an option for me

Good point

Good luck with it

[Duncan Grier]

Thanks Bill, happy to wedge you in the pax seat if you want a lap ND - trust me I do need to loose weight atm or going nowhere in it lol

Maybe even Mart on his new special K diet will fit come ND

Cheers mate - I'll bring my giant shoe-horn . I'll need it! I've been doing nothing but sit on the sofa for the last 6 weeks, thanks to a knackered head/neck/chest/back/arm/hand

[Mart]

Fecking hell, that's gonna be insane mate

Got any pic's of the beast?

Look forward to seeing that rip around Mallory & Spa

Still won't catch me...

[Sparkie]

its fairly easy to get 450bhp at the wheels from that lump. cheap too...
turbo xs stuff all the way....

[Adey aka Ewok]

Backwards on fire into a tree, enough said ;-p

[Duncan Grier]

Well think on big straight at Spa I may let you keep up Mart as it makes the EVO look VERY streamline lol - this really is a brick with cage sticking out prob need 1000bhp to go past 150

Adey it will be fine - got a plumed in fire system already....may want to get a service and refill to be on the safe side

Cant see 450 at the wheels be anything other than dangerous but may wind it up for the pod day and hold on tight!

[Duncan Grier]

Small update;

Went to view the doner car but was not as advertised and we could not agree on price so did some further measurments while there and realised the read diff may not be an option so prob use the cossie one but other than that looks a compact setup for what it is - am not going to be able to retain the cast manifold but not 100% sure until its dropped in. Box looks fine and the ratios all suit - so still on the look out for donor bits

Due to lack of time and ND getting close I have decided to do the project in 2 stages to make sure I have the car to drive at Mallory

Stage1
1. Retain oe engine / box and some tweaks to improve what there;
2. Some lumpy cams
3. Fettle with the twin 40's (cant justify paying for twin 45's when the engine is not staying)
4. Full going over service
5. Get it mapped
Should give 190bhp - limit of 7500rpm or it was solid lifters and all the extra cost of head off and although 220bhp is avaiable it would be itb's or at a min the twin 45's which again adds up too much

Then there are outstanding things anyway which need doing
1. Fit new seats
2. change disc / pads setup
3. full geo setup and test suspension etc
4. spare wheels, slicks fitted
5. Maybe l/b the fly
6. New colour scheme and sort the dash
7. service box and diff
etc etc

Stage2
1. buy engine, box, ecu etc etc for the conversion
2. service while off car

Then it will be pull the old stuff out and start the magic but have the old stuff to drop in at anytime for track day etc if it has not progressed enough or waiting for funds to clear

But cant see it happening in time before ND but plenty of time befroe Spa

Big thanks to Penfold who is helping me out ref some collection of parts local

Should be starting next weekend and hope to have it mapped for the following fortnight

Race you ....not on track though of course that's not allowed ..I'll race you in the garage
Should be quite a handful when you're done

[Flan]

Good engine choice!!!!

Ive got an SR20DET in my Luego with locost GRP. Its a tall engine and mine stickes out the bottom a bit (only been through one sump) lol

I had to cut the chassis to get the engine as far back as posible and the box in the tunnel. Im only running stage 1 (about 260bhp) and that allot of fun!!!

You can wire them up with 6 wires if you get a nats free S14 (not s14a(Facelift))

anything you need just shout

Flan

[J$£5GTT]

its goin bananas in the grier hood!!!!


look out!!!!!!!

[Duncan Grier]

Flan thanks for the offer and will def take you up on the offer

Clee we never race on track you know that in fact last time I as on track with you (oulton) you got mad and raced yourself in to full on spin off the track and was blaming the car

Really looking forward to getting started with the engine conversion but going to be very tight as the locost is a lot thinner than most (wide bodies other 7 replica cars) and want to cut the chassis as little as poss

I have finally managed to get time to have a good look at the car in current stage and is a LA Gold version built by Procomp Motorsport so is not restricted to the reg of the normal locost race cars. Basically the chassis is different (better) and a lot better handling with mre trick bits

Sump was a worry but will work something out

DG

[clee]

At least I didn't go off on the sighting lap

[Flan]

No Worries Dude, my chassis is a narrow type to so it will fit LA golds are very good! Matt at Procomp Motorsport did all my suspention set up and they know their stuff!!

Here is an early build pic of mine….

Also you can run the std S14 front prop (its in 2 sections) if you make an adaptor like this
http://i13.photobucket.com/albums/a282/FlansS14/23092007219.jpg

The tricky bit is keeping it cool with a big intercooler. Im running a chargecooler. I used to have the prerad at the front but now run a big Alloy rad in the front for the engine and separate chargecooler rad in the boot with fans… works a treet! I also have lots of holes to get rid of the heat… them turbo lumps get warm

anything you need let me know

Flan

[Duncan Grier]

PMSL

I will never live that down!!!!!

After giving Adey a load of crap (banter) also about there been tuition available I do a 720 spin out of druids on a sighting lap lol - FAIL pulled in after the lap and got told if I had not done much track driving there was instructors here today who could help - thanks for that

That VX in the wet/damp was a handfull and took me a while to get the less is more correction to snap oversteer

Yes, Procomp have done all the previous work on the car and def know their stuff!

Will have a look at the links later today (must actually do some work ) what diff did you run? The S14 looked big!

As it has been done, and you def know what your talking about I may get this done a lot quicker than 1st planned......feel I will be owing you a fair few beers

Bring on Spa!!!!!!!!

DG

[Duncan Grier]

Cams and Adj Verniers ordered and due this week

Got to love trade discount!!!!

Order service items this week (trade discount not so impressive)

Got it booked in for RR session and have a good play with the twin 40's can only go as big as 36mm choke/venturi but cheaper than buying a set of twin 45's!

Discs and pads setup revised and confirmed so thats getting ordered up this week

Pulled in a favour with a good friend (2bluar) who will be be making me a silencer that works (he does all the stuff on VX's for me and quality is A1) - current one is VERY VERY loud and would poss not even make Mallory

Almost a danger of getting a few cheeky pics uploaded

DG

[Duncan Grier]

MASSIVE thanks to Shop Boy (aka Penfold, aka Chris Smith)

Collected my cams & verniers today and managed in true PMT styleeee to get some free bits thrown it

May be collecting the SR20DET lump and most bits this weekend which causes a slight dilema as want to start this but playing it safe with zetec upgrades but of course adding extra costs

Also a BIG thanks to Flan for his advice

DG

[Rob@Backyardracing]

Sounds awsome... looking forward to this...

[Duncan Grier]

Well slight change of plans -

Not fitting the new sexy lumpy cams and adj verniers - so need to sell now

But on a happy note collect the engine Wednesday after work and should have a gearbox at the weekend........................so between other comitments have 3 weeks to do the full conversion

And limited in spending full weekends on it so should be interesting but owed a LOT of favours off some good friends who have the skills to assist and calling them all in

It BEGINS!!!!!!

Blame Flan for the final push after a chat with him to get some more info

[Penfold aka The Dealer]

Want me to keep the cams until you sell them? The boxs are un opened.... would kent cams take them back??

[Duncan Grier]

Still post them sir

Easier for me to advertise, sell post etc than put you out any further

Don't think they would take them back tbh but should have no problems selling them on as they are used a lot in the 750motorsport club for the race series now

DG

[Duncan Grier]

Small update;

Engine collected and in the garage - need a few items to complete it but need to confirm a few things 1st and mainly some gaskets, studs, bolts needed other than injectors, actuator for turbo and coil packs (may not be usnig these though) oh and AMM

Turbo in the post - retaining oe T28 A/R60 for now on std manifold which I already have

Collect gearbox next weekend and just need to get a clutch and flywheel (prob use a l/b fly)

Been harrasing Obi One Scoff and getting him to do the mapping and just working out best option for ECU - have a full Emerald but its an older version so need to see if its upto the job if not Adaptronic it is. Had a look at the Apexi power FC stuff but seemed a lot of cash for the ones I found and at least with standalone I can use it on anything else in the future if things chnge around.

Could retain oe ecu but not a fan of having my bum smacked by (tuners lol) for any mods

Collecting the car from my friends garage for next weekend also and will get it stipped ready for (pending other commitments) off to my friend to help with the chassis work (he is busy finishing Lee Nobles new car this week which is at Mira getting smashed up for testing )

So will get some pictures up by next weekend to try and keep you all interested

Just hope the live axel / diff setup copes with the new found power lol

DG

[Duncan Grier]

Bit of a delay due to a family bereavement

But back to a happier note!!!!!

Now have a gearbox in the garage, turbo, few other smaller items I needed and just reviewing the spreadsheet of doom for the build as time is really against me now

So the track beast is getting dropped off by Rob thu early evening and Friday is strip back to chassis ready for the following weekend off to Dave's unit for the chassis work (plan to try and get it done in a day with the 2 of use)

Then get the pipe work done back at mine, got a few I/C's in the garage to trial and called in a favour for some free alloy rad work (new radiator and poss tweak or new I/C)

May need to steal one of my engine stands back off Clee for a day in fact while you there Clee might as well help lol

Then get Obi one scoff in for some super linear power delivery and should be finished about 3hrs before the track day LOL

Will get some pictures uploaded for next week

DG

[clee]

I'm going down to Leicester either today or tomorrow so are you in ? Or I can just throw it over the gate

[Duncan Grier]

Clee give you a shout later, I need to go over to Leicester at some point this week to collect some other bits and also Rob is collecting a trailer from my friend nr Loughborough which may save you some time to drop it there?

At worse Sarah is in so you could just drop it off

Can't believe your not up for doing some labour shame on you lol

Thanks
DG

[Duncan Grier]

Quick update and will try to get the pics uploaded tonight if I can find the lead for the camera

Well had a about a day spare in the end spread out over the long weekend and got all the old bits out and stripped back the loom and split the ECU bits out and cleared up the wiring for the Spa dash and associated bits (sensors etc) and then was left with a very small space for a big engine and box lol

Then test fitted the box – 1st problem – it didn’t but 2 cuts will get it in and just need to weld back in a slightly different place and also some of the extra (if you can call it that) space to the left of the clutch pedal needs to go but then after some serious tape measure action it will go and the offset between the box and diff is not as much as 1st feared and should be fine.

Engine was never fitting to start but after removing most thing and will need to mount the alt on the turbo side it fits but need to remote the oil filter or mod the rack so remote it is. Looks like after more tape measure and spirit level action it all lines up….JUST!!!! and may even get away with leaving both of the 2 main top sections of chassis I thought would have to be cut

So this week need to drill out some rivets to release some of the chassis to cut and hope this weekend to get it in the unit for welding and make the mounts etc, there is def going to be a bonnet buldge but will make good effect of this for a practical reason

Also found one of the dampers has lost its pressure so something else to do
Amazing how much excess weight was on the engine with the aircon pump, p/s and the big steel bracket holding it on all weighed

So after a large moment of bugger it don’t fit what to do now 3hrs fresh mon morning have pictures of the engine in the car and lots of drawings for the fitment

[Duncan Grier]

In fact have a couple of pics on the phone if someone pms me their email address and wants to host them on here can send them over. If not then have to wait for me to get the lead

DG

chris.smith@rtoc.org or txt them to me... btw been to the post office..

[Duncan Grier]

Double thanks sir

Just sent them, got step by step ones and some close ups of all areas I will get done at a later point pics sent only showing the engine in place

DG

[Penfold aka The Dealer]

[Duncan Grier]

[Duncan Grier]

Ok, still no camera lead but arranged to go my friends unit this Sunday to do the cutting / welding and review some engine bracing as it sits very high out of the chassis and prefer to be on the extra safe side

Thanks to Adam L who has helped with a few things much appricaited

Happy the bigger stuff will be done in time still but there are a few smaller items to track down and setup I fear are at best taking it to the wire

Even the S3 is in the garage getting fixed so atm have the omega estate LOL

DG

[J$£5GTT]

looking a bit chitty chitty bang bang DG!!!!......


boomski im sure it will be a rocket...

[Duncan Grier]

Yeah think the headlights are going lol. Had to be on for race regs

[Adam L]

That engine in such a light car is looking for some dangerous potential. There's a couple of guys that have done the same on sxoc and one of them is being built as we speak with 1000bhp per ton, which frankly, is ****ing stupid

I am eger to see this unfold. Like I said to Duncan last week, my car does rolling burn outs all through 2nd gear with 255 semi slicks on the rear, so this is going to be sick!!

[Duncan Grier]

Very quick update but will put more when I have time,

After a full day on sunday (after taking way too long to load car with engine etc and car on trailer etc etc) got to work on double checking everything before cutting the tunnel to get the box in, spent some time working it nice and far back without any major cutting and happy withits position, then onto the engine and had a comp between engine rotation and box which wanted to sit staright (gear mech section) for the car but then the engine was sitting at slight angle and visa versa

In the end settled for the better gearlever location and slight angle on the engine, happy its not an issue but still bugging me this morning and may review lol, some meaty mounts made up and called time with it all back in the car nice and def not moving

Chose not to cut a main bit of the chassis in favour of custom tubi manifold so fear time is against me now and maloory looking a bit too close but will carry on and see how it goes but rather do it right

DG

[Duncan Grier]

Mount started - need to finish off some welding but enough for now while sort out other needs. Same other side



Gives a better view of the angle of the engien I ended up with but still grumbling about it




Opted to create a buldge in the pax side of ali sheet and only make 1 cut to fit box past tunel section - was a decent grade and quite thick so got burnt off, heated and stretched never worked alloy before but had more in it than I thought.



Box in postion

[Duncan Grier]

Enough done for 1 day

Still not got that lead but thought I had better post something even if its a collect of quick phone pics

[Duncan Grier]

Ok dont ask me how because I dont know but just purchased another SR20DET engine but this one complete with box, ecu etc etc etc

Basically I am short of a load of little things and struggling to get hold of in time or a price I am willing to pay lol

So will sell the current engine / box and hope to maybe just run it on oe setup for mallory and then get the standalone on after when there is less pressure and more time.

Got to cut the bit of chassis I tried so hard to leave but it is what it is and have to try and put back as much strength as poss

It may still not hapen but going to spend a full day this weekend coming to finish the fabrication work and start the plumbing etc in the evening next week

THink I may be running out of favours with the unit take over if I dont get it done soon

DG

[Flan]

My Car (clio 20v) wont be done in time so ill bring my Kit car out to play

what you doing for an intercooler.... i had overheating problems to start with running a pre rad for my chargecooler infront of the car rad.

I "think" i have a pulsar gtir intercooler somewhere with one end turned round (both ends at the top)

oh and hurry up.... time is ticking

[Duncan Grier]

Got the full S14 engine, box, ecu and loom etc last night so need ot give it a clean (looks to have an oil leak but been there forever by the look of it)

So Sunday is finish chassis work and engine / box in and then its propshaft and loom etc and hope I have enough bits to make it work - Flan expect a frantic call saying where do this go lol

Cooling is currently using the caterham lavente (spelling?) rad and cooler - that runs 550bhp so should be fine - the v8 s/c thingie - basically pulled a favour from who makes them for the kit as a VERY DG happy price. Will have to mod the nose cone to fit it all but prob worth it in the long run

Got to weld another feed to the alloy tank as its now going to be efi not carbs and got a spare swirl pot and 044 pump so will go for that

I have a good solid 2 full days left to build how hard could it be lol

Be interesting to see yours flan make sure I dont steal any bits

DG

[Duncan Grier]

Not the best pic but you get the idea

I am having to moun tthe rad and I/C both in front of the chassis which actually is better than this layout but the kit is based o the SV chassis which is quite a bit wider so hence my nose cone will be.......well tweaked lol



Have some details pics of the design and build but back to uploading which I am pants at lol

[paul b]

awesome Dunc... nice work

can't believe i missed this thread before, chop chop

[Duncan Grier]

Paul long time no see, if you come and help it will get done quicker

Not far from you on sunday finishing the chassis work and gearbox mount, propshaft, fuel tank mod, alt bracket.....oh its a full on day and not an option to be there till late

Gonig to try and get an hr tonight to put the new engine / box back in and cut a few more bits out spent an hr last night for my spare box to be collected for him to not turn up fecker

DG

[Mart]

Good going mate It's all about the last minute rush-around!

Doesn't look like I'll be bringing the Evo to Mallory, so I'll be after a few pax laps me old fruit
