    172 Track Car Engine rebuild tips

    How common is this problem and what is the consensus on the root cause? I am following a similar path but with ITBs as well, hoping for ~210, worried I'm going to throw a rod out the casing on my first trackday.

    Ph1 revival

    Behind? There is (what i think is) the airbag module in front of the shifter, bolted to the floor, but thats long gone. Im pretty sure there is another computer behind the dash somewhere near the fuse box. Maybe its in here. Will stick the key in next week and see what the light does.

    172 cup, what I wanted to do 20 years ago

    W744WTR! i had a theory a while back that these were some of the first vehicles produced for the UK. You see a lot of W7**WTR in press pictures etc. Mine is W748WTR - so probably came over in the same batch! Love the car though, i was so torn between 2118s and TD1.2s. Went for the latter in...

    Ph1 revival

    Oh thats interesting, i will clean up my old plugs and reuse them to begin with. I am really not sure what map is on the gen90 I have. It is second hand from a 182 but i got the ITB kit inc injectors all at once so maybe what is on there will at least fire up. Thinking about it, now that ive...

    Also - shout out to @KitsonRis for well documenting his struggles fitting this kit to a ph1! And responding to my barrage of questions about it!

    Ph1 revival

    I think my one tip would be to remove the pivot bolt on each side rather than removing the bracket from the body. This way you can avoid the risk of the captive nut just spinning. Once that happens it becomes a massive headache. Downside of that is you need ot drop the fuel tank a little one...

    Ph1 to Ph2 Throttle Position Sensor Conversion

    Digging up again because I now have said kit and am trying to get my head around the wiring. Kit you mention in another thread that pin65 goes to pin41 for the shift light, but that's not mentioned here on any of the sheets northloop showed. Does the shift light work on yours? Also the TPS...

    Cams & Injectors - The same old question

    also - is this the general group-N? or what has been experimented on with 421 cams?

    Cams & Injectors - The same old question

    Wow, wasnt expecting an answer so fast - Thanks. Well while i have your attention - Does the VVT kick in from 1600RPM all teh way to redline? Adding 16degree (advance or r****d?). How would the above be adjusted to compensate running without VVT? I thought the aim was to r****d the inlet so at...

    Cams & Injectors - The same old question

    Digging up an old thread - can someone remind me exaclty what the cam angle changes are for group N? i thought it was 9degree (r****d?) on the exhaust, anything on the inlet? has anyone experimented with group-N timing with 421 cams? I guess your limiting factor is going to be when you risk...

    Engine mount bolt sizes

    Hello - when stripping down my engine i noticed i failed to take note of a few bolt sizes to replace. I dont suppose anyone knows off the top of their head these bolts sizes? I assume they're M10x15mm but what length?

    Ph1 revival

    This was my thinking! I read so much about people getting the wrong lengths with pattern parts and having knocking issues. Especially for ph1s as it sounds like they changed every dimension a tiny amount just to make sure the ph2 parts wouldnt quite work right! Having such a headache with the...

    Ph1 revival

    oh wow, thanks for the heads up, i hadnt considered at at all! this is an engine dynamics one, didnt say anywhere that it wouldnt work with the standard clutch but will check. Drivesaft refurb was £250 - quite steep considering the price of pattern parts but was all proper Renault components used.

    Not really an update, just a photo dump Also had my driveshafts rebuilt by Peter Withers, not sure if he uses the forum or what his name is on here but hit him up on facebook if you're looking for a refresh. And my efforts to convince my dad to sell his vintage bike for more room has...

    Ph1 revival

    Someone threw it in when i bought some KTEC ITBs off them, IIRC they mentioned it was a Tessa one at the time. I was going to just get the PMS one when i get around to placing a big order. And yeh, so far I've gone for, sump not leaking, leave it on. My only fear is when I had to drill out 5...

    Ph1 revival

    Also Also - (i wish you could edit posts) - has anyone seen a breather like this before? I has a completely flat bottom, no machined chanels what so ever, i assume this is part of a larger assembly? It also has no residual evidence of the channels in the rocker cover. I've basically just used it...

    Ph1 revival

    Finally to close, here's a fun thing I've learned, early ph1s don't actually have a keyway in the crank sprocket. I am told that this is because they use a forged crank of another renault but dont know for sure. Annoylingly i had thrown my original one away (or into the rusty scrap metal pile)...

    Cat Cam Question

    Sheered head bolt

    Yes Sir!! Ended up having to drill 5 of the f*****s out! Does anyone know of an aftermarket upgrade that will avoid this issue in the future? I guess i dont ever plan on taking the head back off.

    Ph1 revival

    Head is now back at my flat in London, next job is to strip it down and send it off for some headwork! Will be stripping the head down myself as soon as the valve spring compressor arrives. Main driver for this is that I bought 422 cams (non-VVT) that will require uprated valve springs so...
