172 turbo project

[wozzer]

I bought my phase 2 renault 5 gt turbo around a year ago now, not long after i bought it the turbo blew, then piston rings and liners went so i decided not to fix it and go for the 172 lump the car will be used for track and road use haha if the insurance will touch me, the progress has been rather slow as i have only got a part time job, will keep this thread updated as i go along.

will defo need some advice and tips if any1 has done this conversion b4 as this is me first conversion, i have had a load ov advice of James5 thanks alot

here are a few pics of how it looked when i bought the car.

[wozzer]

then i started taking the engine and all the interior just so it was a rolling shell
i sanded down the engine bay and subframe and sent them of to get sprayed.

[wozzer]

just a few bits of sprayin while i waited for a few parts and saved up for me new engine

[wozzer]

then me gaz coilovers, front and rear disks were fitted and intercooler bolted on

[wozzer]

finally bought me 172 engine with 55 thousand miles, with uprated clutch and gearbox with full rebuild

sum pics ov me new engine, clutch and paint job

[wozzer]

so i got me engine crane, plastic windows and 2 cobra buckets and got to work first i put the windows and buckets in place while i waited for the crane to arrive.

also the petrol lines and brake lines were all removed as they were rusty and also go trid ov the petrol tank

[wozzer]

engine finally in, just waiting for me turbo manifold, heat plate and oil cooler.

also savin for me forged pistons, liners, conrods and rings ( Were is the best place to get a complete set and can you get different Compression ratio s ? ) also were could i get them all fitted ?

[Bruce - BHPerformance]

What front engine mount did you use?

[wozzer]

i just used the r5 turbo 1 redrilled for the minute but i am still on the search for a gtx one i have been looking for nearly 2 months now and renault dealers dont stock them any more

[Bruce - BHPerformance]

Try here for the rods and pistons. Block needs boring if you don't use std size as no liners and I think PEC do MLS head gaskets as well for the 172 engine.

Thats a shame as I bought a GTX one for my F7R conversion about 3 years ago. Was only £18 new from Renault.

Renault have sold out of those mounts a little while ago, more than likely down to how many people are doing this type of conversion now

[wozzer]

ok mate thanks alot i will need to do alot ov saving haha o well i new it was gona take along time, just hope it will be worth it

im gona leave all the engine work to a specialist coz i dnt have a clue

o yeh do you just use the clio 172 throttle cable and clutch cable ?

[Bruce - BHPerformance]

I used a std 5GTT cable for both if memory serves me correctly.

Engine Dynamics do fully built turbo engines for the 172.

I used 5 clutch cable and the phase 1 172 throttle cable due to tb connection end was different to gtt.

[Big Steve - Raider]

Nice work Wozzer!

[wozzer]

thanks alot cables orderd

o yeh wot silcone hose do i use or wud i have 2 get them made ?

coz the 172 or the gt hoses wouldnt fit wud they because the hoses come of differently ?

thanks big steve

[Bruce - BHPerformance]

I used a clio 16v radiator and oil cooler so used std pipework from 19 16v, GTT and Megane 16v that I had lying around the garage.

[James5]

thanks alot cables orderd

o yeh wot silcone hose do i use or wud i have 2 get them made ?

thanks big steve

What radiator are you going to be using? you can use the 172 rad if you have it if not go down the clio 16v / williams radiator route and a large slimline fan as they will fit in place ok you will need to make a couple of support bracket's for the rad itself, you will need to extend the 172 hoses to the heater matrix but some simple joiners and straight pipe will do the job nicely. I used a mixture of my R5 GTT pipes and 172 pipework for my setup.

[wozzer]

will be using the 172 rad and slimline fan looks like i will have 2 buy a set of 172 hoses and r5 hoses and just have a play

turbo manifold shud be here 2moz or tuesday so will get sum pics with the turbo in place, just hope there is enought space for the exhaust and hoses that come of the turbo

[wozzer]

here are some pics with me manifold and turbo on, the only problem is that the turbo is in the wrong place

wot do u reckon i can do ???

mite just leave it like this then connect everything else up then take it 2 a specialist to do the internals and sort the turbo out lol

Do you mean the front of the turbo outlet is pointing the wrong way? You know you can rotate the front of the turbo by undoing the bolts that sit on th back of that near where the oil feed goes.

[James5]

When you say in wrong place do you mean the turbo housing's? if so you will have to do what we did with the F7p turbo's and rotate the exhaust and compressor housing's so it would fit properly keeping the core with the feed at the top. You may need to drill and tap the rear of your compressor housing to fit the actuator in a new location on it


Looking good though, I wonder if you could get away with using the Clio phase 1 turbo downpipe like me and Steve use on our F7p turbo conversion

http://www.k-tecracing.com/show_prod...d=2726&appid=1

[James5]

Just stole the downpipe pic from Steve's project thread on www.renault5gtturbo.com

I know that myself and Steve are doing the F7p conversion's but your turbo must sit in a very similar location to our's, I would have thought this would be ok fo you to use. You can pick them up 2nd hand on the clio 16v valver forum for around £150.00

The pictures are from Steve aka 5teveL's project and he is using the K-Tec downpipe as seen in this pic I am using the BBPT version of the downpipe basically same thing although i had to modify one of my holes to fit my T28 properly.

[wozzer]

hya james no the housin is in the corect place its just the turbo if u look at the pics above the pipe that comes of the turbo to the intercooler is gona hit the bulk head

thanks for them pics that downpipe looks mint,
pics help me alot more

thanks alot

[James5]

I think the downpipe will work for you aswell

Yeah you just need to rotate the compressor housing so it sits nicely, as said you will also need to remove actuator to do this then drill and tap the rear of the comp housing to enable bolts to secure actuator bracket in place once you have got the housing location done. you will prob have to have the outlet facing upwards

Mine is the same you can see my top outlet pipe just in this pic of my bay

[wozzer]

ok mate how hard is it 2 rotate the compresser unit ?

ur engine is lookin mint now wot bhp are u looking at ?

[James5]

ok mate how hard is it 2 rotate the compresser unit ?

To rotate the compressor housing you will need to first take of the actuator, then undo the bolts at the rear of the front compressor housing just slightly lossen them all and you should be able to rotate the housing quite easily and then just nip the bolts back up again once the position is found, as said the actuator bracket will now need to be located in a different place, i would mark were it needs to go on the compressor housing and then fully remove the front housing and drill out to the correct size thread prob be an M6 or something along those lines to secure it, also leave the old actuator bolts in there holes as they may go straight through the housing and then leak boost otherwise.

My engine is ok present bhp is 0, but when running would be nice to see around 250ish out of it.

[wozzer]

thanks for the advice i have managed 2 rotate it and fits ok

got a few pics and 1 pic ov the space for the down pipe

[James5]

Looking good matey I take it your going to have a 90 deg silicone bend straight of it

no need to thank for advice matey if I can help I will, shame your not down south would have given you hand with the conversion

[wozzer]

yeh i wish u cud help me but im in no rush lol so just gona do bits when i get the chance haha o yeh u no u sed use the yellow cozzy injectors http://cgi.ebay.co.uk/FORD-COSWORTH-...item2a11f7b256

are they the right 1ns and wot difference wud it make if i wanted to uprate them to the 803 s ??

[wozzer]

i was just wondering if this is the volvo fuel rail wich is used, so can put bigger injectors in ??

[James5]

Yeah that looks Like the one Volvo t5 jobbie. Check out ashys profile he has photos that shows his mods. You need to move the rail more to the left as your covering thermostat inlet connection. You need to block / get someone to alloy weld the 5th hole

[wozzer]

rad and fan have turned up, so fitted these this mornin and also found a new place for the brake pot

[James5]

Looking good matey, coming on nicely you thought about air filter location yet?? I have mine placed in the passenger side scuttle area, I drilled a 63mm hole through the scuttle area and just ran some pipe up. Battery then re-located to the drivers side scuttle area

Give's you something else to do aswell now

[wozzer]

haha yeh i have been thinking to put it over the front passengers side arch,
and the battery in the boot with the petrol tank ?

just waiting for the injectors ( 803s )

o yeh i went down to me local welder this mornin and he said he could block the hole of on the fuel rail but is there any other way coz he said it mite be risky ? e.g he could put a plug init then weld around the top ?

Best of speaking with Nial aka Ashy as he had to modify his the same.

[SP33DY]

Will a clio PH1 fuel rail not fit the injectors? as it'll save a right fcuk on and the mounting bolts etc will line straight up?

Feck your right the clio phase 1 rail will why didn't i think of that as I use it on mine with the Bosch injectors.

[wozzer]

iv tryed to upload more photos ov wot i have bin up 2 but they wont load for sum reason

anyway iv plumbd all the engine in e.g rad and coolent pipes, welded me volvo fuel rail, located me airfilter were the battery would ov bin, bought me phase 1 carb and fitted, fitted clutch cable and throttle cable also fitted me heat wrappd exhaust.

just orderd some 803s and pistons of ASHY

also how hard is it 2 weld a plate for the top engine mount ??

[James5]

Warren, Ashy cut the top engine mount bracket out of a Mk1 clio shell I think it was and welded it into his 5 You will need to relocate the brake fluid resevoir. I know Ashy has loads of pic's on profile take a peak

Sounds like progress is coming on quick shame about upload of pic's

Dear god man. What's happened to the front bumper?

[wozzer]

haha i no yeh i really didnt want to cut it but the car has been of the road for so long now and just wanted to get the pipe work on it will be on track every weekend so doubt it will stay in one peace anyway

[Matt Cole]
