Default anyone destroked a 2.2l turbo motor to 2.0 l?

just curious.

just a thought that ran thru my head, would be nice to get a high boost high rpm monster, just wondering if anyone had done this before.

I don't really see a reason to do it... I mean, if you're looking to get an older EJ22, why not just get an older EJ20?

Because the early EJ22's were closed deck, forged internals monsters.

Well, so were STi I-III engines.

Also, why would you need to de-stroke the motor to get it to rev? IIRC, the 22B STi had an 8K RPM redline, just like the other STi cars. You would simply need STi heads or upgraded valvetrain in WRX heads.

I'm sure that you could safely spin an STi motor to 8500 RPM with an aftermarket ECU. Cobb Tuning would be a good place to start asking questions like that.

22b runs a 75mm stroke, same a s 2.0. 2.5 is much larger

Alas, the EJ22T has cast pistons, not forged. What it DOES have is a closed deck and oil squirters.

Jaxx i dont think any of the Old JDM legacy engines were closed deck. If they are then that would be a cheap way to get a good block since they can be had for $400 bux. Also the 2.0 and 2.2 share the same stroke so it cant be "de-stroked"

I'm pretty sure the older jdm turbo motors were closed deck. I think all turbo motors were until 1995.

There are more than a few closed deck engines. Look here for details.

Ya those are all Impreza STi blocks. Since STi never made a Legacy(that i know of) I doubt Legacy's ever had closed deck blocks.

All those are STi blocks simply because that list isn't compiled for the gazillion other EJ20 toting Subarus.

The USDM Subaru Legacy Sport Sedan/Wagon all came with a closed deck EJ22. It was not made by STi either. I'm fairly confident that the earlier turbo motors came closed deck up intil the block was revised for open deck to improve the quality control on the casting process and to reduce costs.

Do a search for 'EJ20G deck' on google. You will find your answers.

I'm quite sure that the JDM legacy turbos had a closed deck block. Where do you think the EJ22T block CAME FROM?????? All Subaru "performance" motors were closed deck back then. Even the EG-33

EG33 was not closed.

ok so i did some more research and found that the early EJ20G blocks are closed deck. they were used from 1990 to 1993. http://www.gijyutu.com/ooki/ima-room/2001-9/2001-9.htm has alot of pics of the EJ20G engine. I wasnt able to find any info on the EJ20H and EJ20R legacy engines(94-98 single turbo)

I am using a EJ20G single turbo engine and it is closed deck. The crank and rods are forged, the pistons are not. it does have oil squirters and uses hydraulic lifters. I have read about an STI EJ20G that had solid lifters and forged pistons... Oh and the compression in original form is 8.5 to 1.

so would I have a pretty much bullit-proof engine if i used a 93 legacy EJ22 engine, and got some must stronger pistons, and threw it in my wrx? I want to build an engine that can support 30psi reliably, would this work?

Buy a 04 STi shortblock and call it good. The non-turbo blocks are open deck and donkey p00p compared to your stock WRX block. The EJ22T block IMO is inferior to the current semi-closed deck blocks.

Plus if you can convice SOA to sell you the STi shortblock it will be the cheapest route you can do unless you rebuild some used thing yourself.

the only caviot is that the old ej20G and ej22t are phase 1 motors .. thus have less main berrings..

and one for the trivia .. yes STI did make a legacy it was the legacy RS RA the first STI .. direct linage to the legacy wrc car

The ej22T is hardly inferior to the newer blocks....

Lets see your motor hold 30lbs stock and rev to 9k...

If I were to pick a 2.0L motor it would deffenatly be the v7 sti ra... 340+ on 91 occtaine or cobbs 2.0 if you had the money. It would make no sense to destroke the ej22. If you want to run 30lbs the ej22 is a good start new rods, crank, pistons; but 30lbs on any motor wont last you long.

You should look in to sti v7/8 heads or again cobbs heads. wrx heads with there low flow rates and short deration heads will not be a very good match.

You should also take a look at cobbs 2.2 with its 8 to 1 CR.

Just remember that the phase 1 motors were done away with for a reason, and make sure that if you get a motor with oil squters get the oil pump for that motor.

I agree with totoherbs, the original ej22 turbo engine is one of the best engines so far (stock to stock comparison). Unfortunatly the it wasnt available as widespread so not many had access to them. Even so, the stories you read about them are pretty amazing.

For example, a 100% stock engine with 130k miles running 25+ psi boost for extended periods with no reliability problems.

Well My EA-82T did 15+ psi non-intercooled on 87 octane in 100+ degree temps all day long no questions asked.

Really relaiblity is all about keeping detonation away and living through a couple minor det events.

The EJ22T or the EJ257 will do that.

The simple fact is the world has moved on since the EJ22T was made. The improvments in the current blocks are not poke you in the eye obvious, but they add up to one heck of a sweet block.

Oh and on the 9K bit? Last time I did some calculations on it IIRC the EJ25's stroke and rod lenght means that it sees approx the same stress as a Teg Type-R does at 8K. So my guess is that if you really wanted to a stock STi Type-US motor could take 9K on the bottom end. But you still would have to get some stiffer valve springs to make that end relaible.... and I wouldn't do it anyway unless i had a nice reserch motor to play with. 8K will be fine for me once the ECU is cracked.

Sorry to say, but the EG33 is NOT a closed deck design. I've got one apart in my garage and it is not closed.

I love it when people throw out boost pressure numbers with no other info. 30psi on what turbo? A horsepower figure would be much more applicable. Why do you want to run 30 psi?
