Renault 5 gtt / 172 / 172 turbo Project

[ashy_gtt]

Hello,

Just thought I would share my latest project with you chaps, some of you may find it interesting, some may not... But here goes...

I've been into R5gtt's for about 6 years now and owned nearly ten of them. My latest project was given to me in the form of a fairly tatty rolling shell... It was fully stripped out no dash seats etc... engine had been removed, and it was in a bit of a mess...

From the word go I knew I wanted to make a track day car, something light but with a pokey reliable engine...

I set about it, cleaning out the inside, fitted bucket seats a roll cage and harnesses. Next came the engine, I decided to go for a 172 engine for reliability and power... so set about sourcing one and dropping it in.



The first engine had a dropped valve so that had to come back out and was replaced with engine nuber 2!! I fabricated the manifold to suit, and ran it on a DTA ECU



The bonnet needed a bit of a lump in to clear the taller engine

and its been running like this for a year or so and its fairly nippy, i had it rolling roaded on Motorscopes new rollers at a RTOC day out and it made 173bhp which was nice... However I missed the turbo rush and as with all things it started to feel slow and boring. So next stage turbo...

 

[Fred@BTM]

i'm upset at the bastardisation you've done to that manifold!

 

[Lagerlout]

Does look a bit ghetto lol

Look forward to seeing the turbo version!

 

[ashy_gtt]

So I set about re-building engine number 3

Machined the pistons down to drop the compression -



Machined the flywheel to take my multiplate clutch -



Stripped the block & Painted it yellow :dead: -



Blasted and powder coated the inlet manifold and plenum - :evil:



Knocked up a manifold and downpipe to suit a T3

 

[Fred@BTM]

ah ha, i've already seen this car at pod i believe

 

[ashy_gtt]

One of the problems with the NA engine was movement, it rocked about too much on the gtt mounts, so I had to brace it with a bit of a pikey stabiliser bar onto the strut top.... So once the engine was removed for the turbo conversion I decided to weld in a clio top mount...



Here it is primed -




And painted -




Sorted, now to drop the engine in....:quiet:

 

[ashy_gtt]

ah ha, i've already seen this car at pod i believe

no, thats Scoff's, much faster than mine will ever be!! LOL

 

[Lagerlout]

f**king brilliant is this!

 

[ashy_gtt]

i'm upset at the b*****disation you've done to that manifold!

3 manifolds were killed in the making of the two new ones

 

[ashy_gtt]

so, new engine needed a better fuel rail and FPR that could cope with a bit of positive pressure, so instead of re-inventing the wheel I stole Scoff's idea of using the volvo T5 fuel rail... with a bit of machining i made a bracket to mount it to the inlet manifold.

and fitted that to my engine



I also machined a new turbo oil feed banjo as the gtt one I was planning to use wouldn't fit properly...



SO thats where I'm up to, need to make a few adjustments to the MAP but I'm hopefull that it should fire up this weekend...

Goto fit a new power steering pump to my Vee first, but for those who are interested I will keep this thread upto date with my progress

Heres the Vee



I'm sure I've missed bits out, but It's a lot to fit into one thread LOL...

 

[Pasty]

brilliant thread. keep it updated!!

 

[Ali]

Fantasic mate! nice to see another mk1 Illiad vee!

 

[fmp_]

AWESOME!!

 

[Neil G]

Very Impressive...good work

Like to see the end result

 

[MATT BLACK]

Clever man - spot on

 

[kpowell911]

f**k me this is gna fly

 

[fani]

nice job you are doing with this car ! this is gonna be a hell of a ride.

 

[sh33n]

Keep updating this, nice to see it progress.

Wish I was good at this sort of stuff, bet it will be a right little beast once complete.

 

[The Big Dog!]

Very nice mate seen your car on rtoc quite a bit but i'm lovin the new conversion! Are you goin for low or high boost setup??

 

[ashy_gtt]

Well what a weekend, after burning my starter motor out yesterday I managed to find another one in the garage today

Slapped it on and tried again to get her to run... Found that the pressure compensation map was all over the place (dont use USB to serial converters when uploading saved maps to your ECU it screws all the data up!!)

Anyway long story short, I got her running for the first time

well happy

Heres a vid....

Just needs an oil change then a good mapping session!!

Nice one Ashtray!

Looks and sounds ace!

 

[mini-valver]

Tappety, lol. Done all the work yourself??

 

[theduck]

awesome project!

 

[ashy_gtt]

Tappety, lol. Done all the work yourself??

Yes I have, and its the injectors clicking, yes they are very noisy :evil:

Easy Ralph, hows tricks?

 

[Graham Gooch]

None too bad.

Nice to see the project up and running ! Looking forward to some 1/4 vids :approve:

Well I've built it as a track car rather than a 1/4 mile destroyer... However seeing as I have a set of Mickey Thompsons gathering dust in the garage I'm sure it'll be making an apperance!!

 

[ashy_gtt]

Maybe a moderator could move this thread into the projects section for me?

THanks

 

[cat171]

I just clocked when I saw the pic of the vee, d'oh - How you getting on with it ? (I bought the standard blue one that came up for sale shortly after yours)

Nice project you've got on the go

 

[Mark One]

that manifold looks, errr, well balanced. Praps cylinder 3 (from Cbelt) will experience a little more back pressure than the others!
I can't talk tho, A nice project and if it works and shifts, then thats all that matters!
good luck mate

 

[ashy_gtt]

that manifold looks, errr, well balanced. Praps cylinder 3 (from Cbelt) will experience a little more back pressure than the others!

Why would it need to be ballanced? have you seen a gtt manifold?

you have a fecking grate turbo who gives a sh1t about ballance:rasp:

 

[ashy_gtt]

New dash to go in aquired today (Cheers Steve / Rich)

The cats an optional extra... Should be fun trying to get the wiring sorted!! :dead:

Anyone got a wiring diagram for a 172? also are the looms between the clio's fairly universal? I.E. could i find a w@nkey clio in a breakers and have the loom out to run the 172 dash?

 

[Fred@BTM]

^nope, needs to be a 172 loom

 

[Josh@Renparts]

ive got a ph1 172 dash wiring loom

 

[chris79]

Wow Ashy, just found this thread, amazing work mate!! Please invite me to come and see the finished product once it's done, looks awesome! Get some pics up of the actual car, are you running it on 15's? Keep it street sleeper and standard mate, if you ever consider selling it contact me first lol

 

[Andyman]

Great project and respect for giving it a bash but going by threads on turbo'd 172's there is in some folks opinions still question marks over long term reliability, gearbox strength etc etc
Will be good to see how it compares to a standard GT Turbo engine with similar power

Trust me there would be reliability issues on a Reno 5 running 200bhp +... To be honest tho I very rarely use the Reno 5 and get more fun out of stripping and rebuilding it than I do driving it

Clutches / gearboxs are a right pain... The Helix clutch has always served me well tho...

yh the helix clutch has served me well too!
and i done around 20,000 miles on and iv now bought a new one but theres nothing different e.g worn down?:S
great thead mate!
i was thinking of getting my fly drilled?!?will this lighten it enough to notice a gain?

Wouldn't of thought so m8, I nearly halved the weight of my flywheel, took a lot of meet off so the Clutch didn't foul inside the bell housing!

 

[Fred@BTM]

^proper clutch!
