hi folks.i am in the process of turning my classic wrx into a track day car as mrs wont let me have a big bike again...
have got most bits sorted but looking at rebuilding engine to make stronger.
it has a closed deck block and has only done 52km before import and 27k since so hardly any miles.i have heard that some of the early wrx's had forged internals.is this true or not?
looking to have a reliable 320-340bhp and decent torque.
cheers

 

I believe you engine is more than capable taking 320-340bhp with supporting mods.

......you might brake gear box eventually with that kind of power.

 

gearbox already complaining and got crunchy 3rd and 5th and just trying to get hold of bits to rebuild box.
how hard to get gearbox bits????

 

The only cars with forged pistons are STI's, the rods are common on all classics and are crap. If you get a genuine 320+ and are tracking it I would be suprised if you don't loose a rod or crack a piston quite soon. I would strip it and put a set of rods and pistons in it while the crank and bores are ok, if it does go pop it gets expensive.

 

sounds good idea.new bearings,rods and pistons.what are best around???

 

Cosworth
CP
Mahle
Wiseco

I have wiseco pistons and manley roads combo on my ej257 just had it done and running very well.

 

Gearbox vise you wanna consider 6 speed new age conversion.Fit and forget

....also if you are switching internals go to 2,1 stroker

 

Contact WMS above. Andy's components are incredibly good, I will be using his rods in my own builds.
