Best turbo for big power

[dizzeeR5]

he people.

what turbo would you say gove the best power on a 5... price doesnt matter. has to be resonable tho..

i was thinking vnt but i read somewhere that there ****e fr top end power with petrol engines

some shed the light please. im lookin for massive power road legal track car

[BluntyR5GTT]

t28

[Penfold aka The Dealer]

Massive power? Like what, some say 180bhp is massive, where as some with say 250bhp is massive....

Also what about the engine? Whats been done to that.... no point in having a massive blower with huge amounts of boost if you haven't got the engine sorted, then you need to sort the fueling, cooling out...

Track cars dont need huge amounts of power to be fast ;)

[BluntyR5GTT]

great reply above i agree with everything thats been said please just dont go sticking a big turbo on there and whacking the boost up to silly levels without sorting all the basics 1st:agree:

[dizzeeR5]

i think 250 massive.....

i know about the basics..and im going most of them soon.. steel liners. forged con rods and pistons, re jetted carb,baffled sump, fmic.green cotton filter. any ive missed ? ? i know most of the basic so dnt think im gunna do a novice n bolt of a turbo n let it go bang... hehe. im not that bad

[BluntyR5GTT]

also id change the plugs,leads timing chain and tensioner and alternator belt, what intercooler are you going to be using ?

[Ricardo]

I think i know of 1 person that ran 250bhp but NEVER used that on track, you don't need to. I had 176bhp and that was plenty quick enough at Rockingham, Nurburgring etc. Good enough to hussle Megane 225s out the way :)

T28
Forge FMIC
carb adjusted to 18psi
OE bottom end and head

yep! you missed the most important of all!! :laugh:

The cam

[Adey aka Ewok]

ive got to 208ish on a completley stock botom end and cam before we got float chamber empty with a full t28

[Ricardo]

The R5's biggest advantage is the power to weight

[Adey aka Ewok]

yeah to be fair 180-190bhp stripped 5 on the track will play easily with the big money spenders

[dizzeeR5]

i forgot to put the cam on the list, i was thnking off the top of my head...

"yeah to be fair 180-190bhp stripped 5 on the track will play easily with the big money spenders"

thats exactly what i want..

i was thinking of using the huge front mounts off ebay.. look good enough.

if that the case il look to get 180-200 horses.

it sounds like i was jumping the gun a tad, just excited thats all. hehe:p

[Rob1980]

Is your 5 running around on the road at the moment? I have not seen it about....

[Ricardo]

You say price doesn't matter and in the next breath say it has to be reasonable,so how far are you willing to go?

Full bottom end rebuild, pistons, liners, balanced lightweight parts to start.

[dizzeeR5]

Its sorn at the moment rob... the rust bug has got her, has been for a few years. just getting my arse into gear finaly..

i dont mind what its cost but obviously it cant be silly money. but all options though about tho...

[Rob1980]

Is that really needed? With a correctly fuelled carb an uprated cam and say a T25 at 16psi, a standard engine will not be too streached or an I wrong?

Same as mine and it has been for a few years. Im hoping to get it back out very soon though.

If you have good compression on 4 cylinders, it's not smoking and it's been looked after? I bought a 2nd hand C1J that was known to be good, dropped it in, had the carb adjusted,hey presto 176bhp, 174ft/lbs

Depends how you want to go about it, just drop a lump in, or are happy to rebuild your own so you know it's all new

[dizzeeR5]

same here. gunna strip her down. repair the rust. the spray her white (yummy), then put her back togeather. hopefully done buy the end of this year.

gunna try my hand at a carbon fibre dash aswell....

Very good answer. I had mine fully rebuilt just for peace of mind. As I could not do it myself it cost a fortune though! All that just to sit off the road with only about 2k miles of use!:cry:

[dizzeeR5]

i need to rebuld mine... 110k on the clock no reciepts forany rebuild i can see... been looked after tho.. juts ive had it for 4 years just sitting there. feel bad for her really

[HULK]

Big laggy turbos are only really suited for dragracing such as a T28
The best turbos for a track car would be a t2/t25 or a full t25

[stu21t]

Your origional question,
what's the best turbo for big power on a 5?

My answer,
on my 5, either a roller bearing t4 so I can use my antilag and launch control
or a gt30 but no a/l, l/c.
Lol

[dizzeeR5]

whats your anti lag system stu ?

[stu21t]

my answer was a bit tongue in cheek
my 5s not got a c1j m8

[dizzeeR5]

oh ok mate. lol mebeing dence then. as normal

[stu21t]

not being dense unless you know whats in my 5, as youre fairly new then i doubt you would.
just me having a quite moment. lol

Cosworth powered 5, wouldnt mind having that kind of power on tap. :)

Show off:laugh:

Just because you have a Y.B:laugh:

[Penfold aka The Dealer]

Dizzee, Rob i dont know if you are free on Friday, but why not come down to brands & meet some of us and see the 5's on track...

Oh btw i would look at this engine...

Built for track in mind & cheap, alot of good parts on the engine..

[dave r5]

drop in a volvo

good power and good torque for little £££

110k is just run in :agree:

Mine's done 150k - at least 20k have been on track, and hard (when Mart drove it anyway :laugh: ). I personally think that you should never crack the engine open unless you REALLY have to.

Totally agree mate :agree:

[Brigsy]

If it aint broke don't fix it:agree:

[Ricardo]

Exactly, i'm sure Colinski said an untouched OE C1J is spot on

[Mart]

:agree:

And for sure, for only ~200hp, forged pistons & rods and steel liners certainly aren't required.

[Ricardo]

180 square even on a low comp OE shagged C1J squire :cool: :D

[Mart]

Exactly Mundo mate.


Ol' Trusty was running around the same power, ish, and that was a hoot to drive on track.

:cry:

Likewise i do miss the C1J track attack

Boost was increased to 21psi ;) :cooter:

At 20psi+ you will muller most cars on the move, I loved my car on the motorway :D

[dizzeeR5]

i was thinking of running 20psi+ would i need new liners ect.. well excited now. can come to meets aswell.

If your liners are in good condition then no you won't need any, best leaving them in

First thing to help assess the engines health is a compression test, as long as the readings are within 10% of each other, its a good start.

New plugs, leads, dizzy cap and rotor arm. Plugs wise, the standard plugs or Ngk b8 evx's...or even the Campus plugs :p

Flush and refill the cooling system, make sure it's doing it's job...is the thermostat ok and is the fan cutting in as it should? Is it cooling properly and generally good all round ie not losing water and pressuring etc

New engine oil, pretty much anything other than just a mineral oil...

Find a turbo that'll suit your needs...

Ask someone to help tune the carb for boost...20psi requires a bit of fine tuning as some jetting works well on some engines and not so on others.

I've only been a GTT owner for a few months, that's what I've learned and it works well :D



;)


Maybe upgrade the intercooling...carb freeze will **** you right off :wasntme:...

well you did say the campus would be cool mark ! but reaching sub zero was way to much ! :laugh:

[dizzeeR5]

im going to replace most things anyway for peace of mind .

im getting anew intercool of the company, cant remember there name. its a custom jobby tho....

I need a Campus turbo in my life...with the worlds biggest fmic :laugh::agree:

World's biggest :sad2: You seem to of forgotten about my other one! :laugh:

It's not too big on the campus, about average size compated to others ;)

[Spooky]

We ALL know how big the other one is :D

For a Campus, yours is rather large :cooter:

I really wish I could mate, it would be nice to finally meet a few people on here. I'm doing up my place again all weekend as ite being rented out on the 19th of this month. I'm moving in with my girlfriend to your town, Ashford. I will be looking to get the 5 back on the road after then.

[newbstar*]

:)Time for a local meet in the spring, i think chris.
