Default 92x aero swap

ok so i asked on the saab92x forum and they didnt know to much bout what i needed so i thought id come to nasioc and see if i could get some helpful guidance.

heres the deal i have a saab 92x 2005 with i believe the 2.0t EJ motor, well it had high mileage and blew something in the motor or the main seals.


so now im in the market for a new motor and i would like to upgrade but i dont know what to upgrade to!

what would be a good drop in motor that wouldnt require any extra wiring, but would plug up to the stock enging harness and give me more than the 2.0.

will a longblock fit?

Seriously, a hybrid is probably your best bet. If they are done well they are very reliable and make VERY decent numbers.

Do some searching on here as someone on 92x.com pointed out. It's a pretty common thing.

Yes, but you will need a tune to run the 2.5l... The 2.5l makes pretty identical power numbers in stock form when compared to the 2.0l. It really only shines when you begin modding it, the 2.5 is a torque monster. However, if the car is stock with a 2.5l shortblock you will not notice a tremendous difference in power.

You can place the following motors in your car:

EJ20
LS1
3 rotor Wankel
VW 16 cyl quad turbo

Since we have no idea of your goals or budget the help you are going to get from us is about as helpful as the advice I've given you.

True to some extent.

I had a 16g and supporting mods on my 2.0L, 14 lbs I made around 230 wheel with 215 ft lbs of torque.. same exact setup but with a 2.5L block I made 260whp 290 ft lbs of torque... on the same dyno, same tuner, and same amount of boost.

I considered the car stock with an exhaust, a frankenmotor, and a tune

ok sry for not replying earlier but what im looking for is...


an upgrade from my 2.0, but can drop and plug in relatively easy I.E. engine harness plug up to the dash harness with the matching ecu for the motor.

price isnt much of an issue at this point, im looking for something under $3000.

my ultimate question is how different is the engine harness and dash harness from the STI to the WRX. and if i can go that route which version sti motor can i use?

I think the simplest solution would be an ej207 (that's the jdm sti motor) or jdm ej205 motor (v7 or v8). The swap is really easy, and there is very little wiring to do. An ej207 would probably cost you a bit more than your 3k budget, though. However, the swap would be much easier to deal with than an ej257 or ej255, and would perform better than the typical ej257 shortblock/stock heads hybrid (imo).

Read all the swap options before making a decision. Some places do great work and others do bs. To do it diy could take weeks or longer.

Trans. yes you can use the 5mt if you rewire some stuff. Yet the 6mt would be stronger.

Common choices...
short block swap ej257 or ej207 with wrx heads with no avcs. (hybrid)
long block sti engine using 2.0 wrx intake. (hybrid long block)
or the full swap of the ej207 or the ej257

You have a lot of reading to do.

What? That doesn't make any sense. You need to do more research. Search "drive by wire."

A turbo is the least of your problems.

I don't like the idea of doing a AVCS motor swap on a car without AVCS unless you wire up the AVCS, you will never get the full potential of the motor, that is why I opted to build the 2.5 with 2.0 heads.
