EJ205 and sti 430 crank?? Stroker kit?

madangel · 01-24-2013, 12:52 PM

I have a 04 wrx that needs a rebuild, and i also picked up a 02 block off craigslist to biuld it u an minimize the down time.

I found a 2.1 strocker kit that comes with the 430 crank-79mm.

I read a while back that some blocks and cranks have the trust washer in eigther #3 or #5 position but i have not found the information again

Can anyone tell me if this crank will work?

99 and up all have the thrust bearing in the #5 spot.

So yes it will work.

Ok, does anyone know what commission ratio I should have using that crank?

Depends on the piston you choose. You need a custom stroker piston, and most of them are 8.5:1. If you use a standard 2.0 piston, it will go above the deck.

Good stroker pistons include Cosworth and Mahle.

Does anyone know of any problems with going up to a 93mm bore, any known block failures?

In general Pros/Cons?

Manley has stroker pistons a well. I run them.

I would say do the minimum bore that is needed. 93 is only 1mm over stock bore.

JE stocks the stroker pistons.

Their off the shelf 92.5mm 8.5:1 pistons are going into my personal 2.1L stroker for my bugeye project build with a set of my standard length rods. Keeping it light and strong!

How long have you been running them?

madangel · 02-07-2013, 12:45 AM

Ok, so I'm starting to buy all the parts now. I'm getting a Stroker kit so that will take care of the crank, rods, pistons, and bearings. I already have a timing belt kit with the water pump also. And a set of Manley valve springs. So I need:

Oil pump - stock or something else?
Gasket set - any suggestions? Where to get a good deal?
93mm head gasket set - is .027 the thinnest available?

Am I overlooking/missing anything?
