Hey I have a thread running in the technical section which is pretty much identical to yours

http://www.rtoc.org/boards/showthread.php?t=18449

i'm looking to build an engine for a trackcar which will be road legal but not a daily driver. Personally though I'm not fussed about mega power rather just get the maximum I can from the standard internals without compromising reliability.

uprated gasket 1.9mm and 12.9 high tensile head bolts are a must!

No need for half the stuff mentioned here, a good cam timed correctly, good spec'd turbo, good intercooler, light flywheel and sorted carb and you'll see over 200bhp. Make sure the fuel system is in good condition too.

You can use standard headgasket too if your sticking to standard comp too and the head i full thickness, i use the stronger bolts though.

I wouldn't bother with ported head or tubular manifold though.

When rebuilding the engine one thing to make sure you do is check everything correctly, if something looks suspect replace it, if it looks in good condition then its fine to re-use if within tolerance.

I's like to say - good luck with building a track car with up to 240 BHP :eek:

I agree with what Mark said (although I do have some of those mods which I'm happy with ;)) It depends how far you want to go like with anything. I'd say reburbish/renew everything suspect, new bearings/pistons/liners ets and a decent cam with a well fuelled carb.

If you're using it on track then get some decent suspension (Koni :agree:) check the whole braking system, and use some Ferodo DFS2500 pads.....

Ye I've sorted the suspention gaz coilovers all the brakes are brand new calipers and brake lines arenew aswell most of the car is new or uprated to start with
