Default 2.2 swap into 2001 rs

I have a 2001 RS-T and i blew the rings in my motor. I am kind of tight on cash and need transportation I really want to get a nice set of pistons and a nice set of rods and rebuild the whole thing but I just don't have the money. I work at a subaru dealership and i can get a 2.2 rebuilt short block from Subaru for $1,300. I would use the stock 2.5 heads and i am using a Turbo set up out of a WRX. Will everything bolt right up? How much power are the components capable of? Has anyone done this before? I am looking for known inormation only no speculation.
THANX,
Bryan Braley

Well if its a ej22t then you good to go... great motor same as in the 22b. If its just a ej22 then it might not be worth it.

um, im pretty sure that a 22b is an ej20 stroked to 2.2L, not an ej22t.

Also here is the jist of it:

EJ22g VS EJ22t

EJ22g, naturally aspirated, open deck, dual and single port heads, spanned OBD1 and 2, no oil squirters. avl, 9.7:1 compression. Found in Impreza L, LX and Outback's
~140hp. capable of about 4-6 psi unmodded internals (usually loses head gasket)


EJ22t, lightly turbocharged, closed deck, single port heads, oil squirters, only OBD1, 8.1:1 compression. Found in rare turbo Legacy's only. ~160hp. come stock @ 7-9PSI wastegate/nonintercooled. can run as high as 18PSI? unmodded internals.


I know that might not be super accurate, but it is a general idea. hope that helps.

well... um... no. Theres a guy on here whos gone 30 psi and does do 20 psi everyday on a stock 2.2. He also said something about spinning it to 11k and then a 9k run around track before it finaly blew a rod barring, all on a 100k mile motor. NOW im not saying slapping this in your car will make it bulit proof. If you dont know what your doing you could blow it on 3 psi...

somebody please do a search! the EJ22t is the 22b engine. i have been running same engine and heads for about 20k on 20psi. you just need the right fuel setup (555cc for me). you can only run about 10-12 psi with stock injectors. and xypher is running 30psi with bigger injectors than me (850cc). if its not a rebuilt motor to the average tuner these blocks are indistructible. my block has about 40k total on it, bought mine new from the dealer for the same price.

look for the thread where xypher tells all in this forum. it is very informative.

I've got the same setup with only SOHC heads being the difference. See a couple post down about the hybrid. FastRs, what turbo are yo running? If you want to run 20-30 PSI I'd suggest getting your valve train upgraded.

I don't believe so... it is an overboared ej20... only found in the 22b...

From www.22b.com
Quote:
The engine was bored out to 2.2 litres, retaining the same stroke as the stock 2.0 litre engine. This had the effect of giving the car a torque curve that wasn’t even a curve. It is a steep climb and table like flat line, when plotted on a graph. The increase in mid range performance gives the car 70bhp more than its 2.0 litre brothers, at only 3,000 rpm. Such was the mid range power, that many respected journalists embarrassed themselves by stating that the car must produce over 350bhp. No 22B has broken the voluntary power limit, in standard form.

STi takes the engine and bores out the normal 2 litre lump to 2.2 litres. This will allow more torque at lower revs.

Think about this... they would take an open deck 2.0 and bore it to 2.2 insted of useing the semi-closed deck 2.2. The 2.2 is also a a low pressure cast and not the newer cheeper high pressure cast.

Question 98 ej22e?

this thread is very informative, but according to my manual, my enine is the 2.2 ej22e compresion is 9.7:1.
its a 98 wagon from canada.
what i am wondering is this the same engine type as the ej22g?
and if so i really want the extra highway push of a turbo.
"i had a 84 gl turbo back in the day" i do not want to swap engines as i am looking for a mild turbo that will give a bit but not destroy my engine.
is there a prefab kit out there for my car? or am i sol?
i have been looking high and low with no luck.
