you should really promote your self a bit better mate this build is awesome to say the least the quality and attention to detail is mega I'm sure loads of loads people would be knocking on ya door wanting work done
172 Cup
So come on then, spill the beans! What's your company mate? I'm genuinely interested if you're happy to tell us. :up:
Top work as always mate.
Ah, I was trying not to promote it too much as I didn't know whether that was allowed! My company is SaloonLibre and it's fabrication of pretty much any sort but mostly cages and arty things like exhausts and suspension bits. This is by far the biggest job I've had since setting up!
Yep, that's me too! That was my own build but sadly setting up the workshop had to take priority. I'll probably come back and do something similar (but better) in the future as it's kinda unfinished business.
Haha yeah self-promotion isn't really my thing (other than build threads like this) but I'm getting better at it. Just don't have much time to do it really!
172 Cup
That's all being worked out but yeah I'll be looking after it and doing race / event support. The idea is to make more of them so this is the demo car, but it's also entering some endurance races with 750MC and others.
172 Cup
Just a quick update.. the engine is in and the car is now on the ground!
I also got the first bit of bodywork back yesterday..
I don't think that pic does it justice at all.. the contrast of blue and black looks unbelievable in person :hearteyes:

PS - The colour is Porsche Mexico Blue

Haha yep! The only surviving 205 parts are the blue bits in that pic, the upper steering column, wiper motor, and the lights.

Looks amazing!!!
Any idea on timescale for completion?
Can you work/fabricate with titanium?

So close to having an exciting update but I'm having some difficulty getting oil pressure! I'm not an engine expert so I've started a new thread in the tech forums so this doesn't get clogged up with replies - link below.

Found the problem.. PRV is stuck wide open! (Click for video)
Thankfully I know a guy close by with a spare pump, so hopefully I'll have it running later.

OK so actually it wasn't that the PRV was stuck open, it was completely missing! :fearscream:
The dodgy one (top) only has the spring fitted, no valve.. the bottom one is how it should look.
Got the pump rebuilt now with the best bits from the two spares I picked up, and had 4 Bar oil pressure with the drill. Should have it running this afternoon.

It lives! :grin:
There's a 1cyl misfire that seems slightly more than just rebuild residues, so I need to investigate tomorrow, but it runs!
Oh also the majority of that noise is the floor vibrating as it's not fully secured just yet.

Big news!
Here's how the car looked a couple of days ago.. pretty sad.. engine in bits.. tools everywhere.. oil everywhere.. chasing a problem which threatened to be a total nightmare but thankfully turned out to be relatively simple!
With that sorted I could get on with finishing the build, and yesterday I Instagrammed a sneaky preview of how it would look..
But then today.. after moving 3 non-running cars out the way.. I pushed the car up to the front of the workshop..
Then took it for its first (very short) test drive! :hearteyes:
It looks SO GOOD out in the sun. It looks nice in the pics but they just don't do the colour justice!
I'm still working out a problem with hesitation, which is stopping me from being able to drive it properly. Oh and there's no windows yet. I have a new set of injectors coming tomorrow which (I hope) should sort that out. I have a load of spares but tbh I don't know which ones are already dead, which are dying, and which will die soon, so it's best to just swap out the lot. Fingers crossed tomorrow I can have it running well enough to get some video footage!

Liking it even better now.
172 Cup
He's yet to see it in the flesh, but I hope so!
The real test will be when he drives it..
172 cup
this is fooking amazing mate dare I ask the cost of such a build if your allowed to say
172 Cup
I can't really comment on how much it has cost but the aim is to produce them for around the price of a similarly-equipped Caterham.
To update this.. the injectors made a small difference in that it was noticeably smoother, but it's still not running properly. When you stab the throttle it will gulp air and bog down, then when you lift off it will rev up, which makes driving it absolutely impossible. I have now changed MAP, ATS, VVT solenoid, coil pack, plugs and leads for known working ones from my 172 as they all had identical part numbers. Lambda, injectors, and CPS are now brand new, and I've checked the throttle pot to find that it's also fine; the only thing I haven't changed is the coolant temp but there's an output on the digi dash showing temps I would expect to see. Cam and ignition timing are still spot-on as far as I can tell from the timing marks and everything was built up as per Renault's process.
I spoke to Track & Road as I need to see what the ECU is reading to be able to diagnose the issue, but and he told me there's probably only 1 person in the country who could read the ECU to check live data and that's only a "maybe". Everything is proprietary and sealed specifically so teams can't mess with the mapping so it's designed to be restrictive! I'm going to check cam timing as a last resort on Monday but IMO the most likely cause is a wiring harness problem as it has gone through the stress of being removed, bundled up and stored, then re-fitted in a completely different layout. Checking the wiring could take me days and show up nothing, depending on the cause, so it's looking almost certain that all of the FR electronics will be ditched in favour of a DTA S60, new dash, and new harnesses.
Here's a video of the issue:
In slightly happier news the rest of the build is pretty much finished, including the enormous spoiler!

Just to add to the confusion: the engine apparently ran fine in the car before coming out. However, the cat brick in the manifold that was fitted was completely melted and rattling loose in the shell, and the Lambda sensor had also been damaged by it. That, coupled with the dead / dying injectors, suggests that it had a problem. However, because I didn't see the engine run before it came out the car, I don't know how the throttle response compared to how it is now - the engine runs perfectly smoothly until the throttle is opened when there's a definite hesitation.

Has it got an air leak on the inlet side somewhere ?
172 Cup
Nope! I've had the inlet off more times than I could count and have checked both sections of the manifold for potential leaks, as well as the plenum cover, sensor holes, and the throttle body. It's a mass-density system (in that there's no AFM, only throttle position, MAP, IAT) so not sensitive enough to air leaks to cause this much of a problem.

You're right though, it's mental! Best build on here.
172 Cup
It has a 35mm restrictor plate behind the throttle body and the air hose is 76mm ID, so it should be just fine!
The nice thing about running DTA is it can be mapped without the restrictor if 190bhp doesn't seem like enough. :tonguewink:
