Just wanted to say massive thanks to dan for the 172 ARB idea.
The 172 ARB fits without a hitch. It's close to the passenger footwell, but it seems to clear.
The only catch is, I've had to use OEM 172 outer ARB bushes. The Powerflex williams/172 (same part i think) won't fit. The OEM ones are...
theres plenty of room behind a MK2 bumper. Why not make the most of it. If your going to do a 'make-it-fit' job anyway, then why not get something worthwhile?
edit:
get your f*ing measuring tape ooot! that's what i did!
stop pissing about with tiny ones!
Buy this. It'll probably fit.

Re: Mk1 F4R/172'd Track Car Project
I'd disagree that hubs are made of anything special, i think it's a cheap casting. But I do agree with you that the heat from the welding is likely just to give a material/mechanical stress concentration. Is araldite heat resistant? It'd be worth finding out...
Re: Mk1 F4R/172'd Track Car Project
By what your saying it'd agree that they've worked loose and then mullered the hub as they were worked about. The heat may have had something to do with it. Hotter bolt>gets bigger>longer>therefore looser etc.
The only thing I could suggest as a form of...
Most ECUs will take a speedo reading. It's used to adjust idle iirc. I'm unsure how much it could affect the normal operation of the engine.
I'd say - Fix the speedo sensor. If that doesent fix the running begin to look elsewhere - lambda/MAP/clean throttle etc
A mate did a uni dissertation on electric superchargers. He found he could get a gain on a 1000cc and under engine using the compressor from an extremely small turbo and a very potent electric motor and battery. It worked on the basis that it was a hill climb car and that it was only used for...
so your saying that the post/downstream/after cat lambda has made a difference to the car's running?
Nothing else was changed at all? Were the wires melted?
Maybe this is a difference between 172ph2 and 182
hmm, well if it's all gonna be a bit crazy monies just stick to a 172 block and leave it there. F4R tuning isnt really cost effective imo
edit...having said that - if you've got a DCi 100 ready to go that's a good option. nippy as fook and mega mpg. Just terrible if you ever wanted to track it.
don't buy a whole megane! The engines do come up from time to time. "Matt Black" had a setup going for sensible money some time ago, probably gone now.
The reason for the VAG box is purely because it's better built and will hold more torque. The added bonus is a much nicer gear shift (cable...
common, theres a reason for that. Scoffs 500bhp F4R runs a VAG gearbox to cope with the power. If you want silly power then you need standard components that can handle the torq, not a clio JC5 that you will drain swarf out of in the Gbox oil.
IMO, there are 2 good options:
1) standard 172...
what about one of the larger diesels?? What gearboxes do they fit and will they get between the chassis legs? Theres loads of diesels from the larger vans etc...
hang on. Have you tried changing the pre-cat lambda? and are you sure it is the lambda at fault? is it in limp mode? have you considered anything else (map sensor...)
edit: I've had my post cat lambda in poor condition, i've got oil on it (not supposed to), and i ran for ages without the sensor...
