I'd happily sink 5k into my Clio when I think I'm not shy of spending 6 figures on my Cossie over the 12 years I've owned it. Rich

Carbone Lorraine RC6's are epic the best brake pads I've ever used, yes theysqueel like f**k and make loads of dust but if that bothers you more than stopping quickly just whack some OE pads in :-) Rich

What kind of times are you getting round Curborough mate? Which layout were you doing? Cheers Rich

How much more depth do the pockets need mate? Rich

Cool cheers for all the advice. Rich

Sound makes sense, what cams would you recommend then? Rich

Any particular reason mate? Rich

Would that be with a ported head and cams? Are you in favour of removing the VVT? Rich

Although it's lot of effort it's not massively expensive where as a set of forged pistons and ITB's are. Just wondering what the gains are using what we have. Rich

Small amount of progress made, 197 engine stripped/inspected and spare 172 block sourced. While it's all apart we were thinking it would be daft not to get the head ported and fit some cams we also like the idea of removing the VVT, so I'm looking for some recommendations as to which cams to...

Having read a few threads on this subject and having a 197 engine to hand it seems like a good idea. From what I've read you just need to tap the 197 head for the water pump idler and it bolts straight on then you fit the 197 pistons, rods and crank into the 172 block and Roberts your Fathers...

Here's my times from the weekend with my 64ft on the far left, reasonable consistent with in about a tenth. Is this about right for a virtaully stock ph1 172 engine (exhaust de-cat panel filter 98 re map) I'm on sticky Avon ZZR's. The start line is normal tarmac an not prepared surface like a...
