Yep,
Most of the tuner shops like Crawford, Cobb and Axis actually refer to is as a 2.2l stroker...

Ej20K is phase I, so you would need a phase I Ej25 crank. Or, as Crawford does on the Ej22T's that they stroke, you can remachine the block to accept a phase II end thrust crank...

Well if nobody wants to admit to trying this combo, then
I'll have to do it and can claim to be the ONLY 2100 cc
EJ engine in existance.
It will be carbed (Webers) & cammed and go into my Porubi

cool.

I don't have enough parts laying around yet to do it...why not do it to a 2.2L block? then you'd have 2300 CC's.

BTW wayne, www.porscharu.com/forum is up and running...come over and play. (except for the fact that we're transferring servers today)

Wayne,
Did you miss the first reply to your thread? It's been done many times...

And I am sad to say that I won't be owning a Porscharu anytime soon. I sold the 914 this last weekend...

can we assume that 2.0 to 2.1 would produce 5% additional HP with all other variables being the same? That simple?

Yes Matt, I saw your reply, but the 3 businesses that you refered to only
mention stroked 'EJ22' and no mention of a stroked 'EJ20'.

Did the jackstands go with the 914 ?

It can be a little deceptive when looking at their sites. A lot of the consumers who are not in the know don't realize that they are just taking an Ej20 block and adding an Ej25 crank to the mix.

And nope, the jackstands didn't go with the 914. They will shortly have a good home under a 1970 911T targa. The engine is too fresh to even consider an EJ based engine swap. It's going to be a restoration type build that will eventually be given to my father as a birthday present for his 60th birthday in a couple of years...
