Default EA82T engine swap possible?

Hi, I bought WickedRydaX's 1986 Subaru XT turbo a while ago, and was wondering if I could put a bigger engine in it, like maybe a 2.2L or a 2.0L WRX engine in it with ease. I know anything can be done with enough money, but within reason. Like, would an older legacy drivetrain fit in an XT? Mostly I want to run more boost, and I don't trust the heads gaskets on the EA82T.

thanks

Rick

Rick,

Yes it can be done and has been done. One guy on the USMB.net site called (Dr. RX) has done this conversion. Took some time to do it right. You can search/post there for more information.

As for the gaskets, why not get copper or aftermarket gaskets from a place like Paeco or somewhere else? If that is the least of your problems, it seems like it would be a lot cheaper than an engine swap. Just how much boost are you considering running?

Sweet, I'll go check over there. I want to run as much boost possible, either that the stock turbo will put out, or what a bigger turbo will put out. A bigger engine would help as well. Thinking I want to run around 10-25psi. I am pretty sure the stock turbo will put out up to 15....maybe. Are the aftermarket copper gaskets strong enough the hold up to 15+ psi of boost?


Thanks

Rick

The head gaskets are NOT a problem on these engines as long as the engine is COOLED and OILED properly...IE: NO OVERHEATING!

with that said...i run the piss out of mine daily. Ive had several RX's that ran 15~17 PSI daily and never have issues.

TQ the heads down REALLY good...like 70 ft lbs or better. MAKE SURE the threads on the block and head bolts are CLEAN CLEAN CLEAN and dab a little oil on each bolt before sending them down into the block.

Hey thanks for the help man! I think an oil cooler may be in the list too. Have you ever changed a clutch out in an EA82? What is easier, to drop the tranny, or pull the engine?? I might pull the engine, than I can work on the heads better. What are your thoughts?


Thanks

Rick

If I had a shop and time to do it...I would pull the engine. I have done it the other way as well. You might as well pull the engine that way you can reseal it while you are at it.

You are Correct, HOWEVER, it is WAAY more imporstant to lube the Bolt Heads/Washers is these, in my personal experience have given more innaccurate TQ readings than threads, (Hence the 'new' EJ angle TQ to Yield style Bolts). ALSO, it should be mentioned that I have spent over 5 years doing NOTHIG but EA's and had them Pull the Bolts out of the Block at 11Psi!!!
IF you are Removing the Engine and Taking off Cyl Heads, I would HIGHLY recommend fitting STUDS in place of bolts. Also, use 1.6mm O Ring in lengths to seal the Cam Housings.....(No leaks for 400,000kms and counting!! )
Reseal the Oil Pump while you are there, along with Cam seals and retainer O rings........
(Although the EJ Series Conversins I have Carried out have much more 'Bang for Your Buck' than ANY EA series.....

Any Info required Gladly Given.....

Cheers and Good Luck,
