After 3 months off the road with a blown HD and broken P1 gearbow I have managed to get a new P1 box (thanks to bannysti) the car goes in for HD in a weeks time, it's a built 2.33, what would the advice be for HD?
I will be running no more than 1.4 bar boost and probably nearer 1.3 bar max
will standard Sti gaskets be ok?

Thanks

1.3/4, on a 2.33 sound sliek it might spit a p1 box straight out. will depend on what figures it runs though

 

Had no trouble with the STi MLS head gaskets,but seeing as your running a built 2.33 stroker - most people use a Cometic gasket as they are available in various thicknesses to get the CR right.
ARP Head Studs will also help with your clamping pressure on the head gaskets.

thanks guys the engine is only running 340/340 it's got a hybrid turbo (IHI)
spools up quickly and has good midrange but wont run more than 1.4 bar
I think I will stick with Cometic Hd
thanks guys
