Engine rebuild

[JohnWRX]

Hello to all,
my WRX 2002 engine have problems then it's was thinking it's time for a rebuild.
I d'nt' want an EJ25, would like to rebuild mine.
With a budget of 2000-3000$ what can i do and where can i buy the pieces?
I was thinking:
pistons wiseco/cosworth (will my open deck support 92.5mm? )
rods cosworth/carillo
hp oil pump
for head gasket i don't know 0.78 or 1.1 or 1.5 mm?????
ARp or cosworth head studs

Really confused about it

thank to all for help

This should get you on your way.

Just like Tom did, search around, the 2.0 has been built up, rebuilt, made into a hybrid, all with great results when done right. Good luck with your build/rebuild.

I've search around, and i'v found that the most have done a 2.5 l, the one i don't want.
Because i live in Switzerland and i can have problems if they see EJ25 and not a EJ20.
Gruppe-s have only 2.5 l shortblock.
I was asking myself what i need for a good rebuild, what pieces...

Thanks

buy an sti crank, rods and bigger pistons . bore you 2.0 out to a 2.2.

I was thinking the same, put inside a stroker kit 2.2l Cosworth, but somebody told me that if i bore for that,the walls of the cylinders of my open deck will be thinner and it's dangerous if i go up with the pressure or at high temp.

92mm and 92.5mm what is the diffrence in power and torque?if there is....
What kind of headgasket i need? 0.78, 1.1, 1.3 or..?

thanks again
