I am running a 2002 wrx 2.1 with a 92.5 bore. I ported the heads and installed kelford 199-e cams with bc springs and retainers. It has modded stock injectors, tomei elh, meth, fp td06-20g, sti tmi, tbe, ported throttle body and tvg deleates. I was only making 325 325 but my six speed got here yesterday and my 20g blew up. So it's time to go blouch dom 2.5 xtr. I hope to see closer to 400 whp. Oh and it was reving to 7.5k.

My own Cosworth 2.1 stroker now running a bit of laughing gas.
Graph shows with and without Nitrous, 75hp jets running at 50% duty through its Alcatek ecu progressive nitrous system.

Too bad the graph is in shoot out mode. That is basically crank hp if I remember correctly.

Read the first two post, and it shows that the windows based dyno dynamics show crank hp.

3" rcm decat from turbo back @ 26 psi /97 Ron gas no additives

P1 2 door classic weight 2800 lbs.

The engine can rev higher than the dyno trace but it was left at 7500 rpm. Previously ran it at 2 bar, but 1.8 was fine for now as this engine is coming out shortly (see below) and anyway in a P1 it's pretty mental. Built for track day use.

Uk style dyno graph ie. at crank.



My car is currently at the shop with an EJ 22 based 2.34 stroker going in and a rotated gt3582 billet going on

I'm gonna be building up my engine soon, but I see a lot of incorrect engine displacement claims for strokers, the numbers for an ej20:
75mm crank 92mm bore 1994cc
75mm 92.5mm 2016cc
75mm 93mm 2037cc
79mm 92mm 2100cc
79mm 92.5mm 2123cc
79mm 93mm 2146cc
I bet its been mentioned before
What does it take to actually get 2.2l out of an ej20?

Crap conditions at our local strip today meant a very poor 11.16 1/4 with a 2.1 second 60ft but with a 143mph terminal

How would you go about stroking a 205 to a 2.2 or even a 2.3 liter?


Might be considering a stroker build on my 205 since my crank shaft may possibly be bad.

Well I finally completed my stroker build (see my build list in previous post )

Mega props to Dale at boxer4racing.com and the whole crew at 42 autosports !

I didn't make quite as much power as I had hoped, but I am happy with the results.

After an entire day on the dyno tuning, reflashing, and tuning some more .

We ended up with super driveable tune, that made 319 awhp 306 awtq

On a mustang dyno, I will post graphs next week when I return from vacation.
