sparkyboy Posted October 25, 2017 Share Posted October 25, 2017 (edited) I am considering purchasing a 91 legacy lsi with a seized engine. I have a spare ej22 from a 92, non turbo. Are there any diffrences between the blocks with the turbo and n/a? If i can simply swap cylinder heads i would flip this car quickly... I also have an 86 GL with a 95 ej22. Would i be able to put the turbo goodies on that car without a bunch of nonsense from the ecu or something goofy like that? I looked at the wiring diagram for the 95 and noticed a boost sensor, but couldn't find it on the pinout. If i steal the turbo stuff for my 86, will my n/a ej22 be an easy swap into the lsi body? I have the ecu. Thanks for your help, boys. Edited October 25, 2017 by sparkyboy Link to comment Share on other sites More sharing options...
Gloyale Posted October 25, 2017 Share Posted October 25, 2017 Lsi were not turbo. just fancy Link to comment Share on other sites More sharing options...
sparkyboy Posted October 25, 2017 Author Share Posted October 25, 2017 So this car must be swapped already then? Guess I will ask him about it and see for myself. Link to comment Share on other sites More sharing options...
monkeyposeur Posted October 25, 2017 Share Posted October 25, 2017 I'm confused. None of the models you listed are a first gen turbo model. The LSi is an na vehicle. The Turbo Legacy is the SS. The turbo and na 22 blocks are different but share the same bore size, crank, and rods. The turbo 22ts are closed deck and about 8.5:1 compression with different pistons. The 22e blocks are open deck and have higher compression. The 22t heads have slightly smaller valves and a return line for oil from the turbo. They can be interchanged. The turbo return line component can be swapped from the 22t heads to the na heads, or one can plumb a line. The 22t valve covers have two breather ports and the na heads only have one. the 95 ej22 is the same as the 90-94 ej22 as far as the long block goes. Cam and crank sensors are also the same. NA and turbo ECUs are different. If you found a boost sensor on the 95, then you must be looking at a JDM wiring diagram since the only turbo legacies were available in the US from 90-94.

sparkyboy Posted October 25, 2017 Author Share Posted October 25, 2017 Hey, thanks monkeyposeur. I don't know anything about the ej22 turbo models. I'll have a closer look at this car and see what the deal is. I am a tad reluctant to start dicking around with my 86, because the swap took me 8 months and is running fantastic, in fact almost 10,000 trouble free miles and beast off road :-) I thought i recall reading somewhere that an ecu from a 99 2.5 will work nicely to boost an n/a ej22. True or no? Link to comment Share on other sites More sharing options...

Not if you aren't racing it. 130 hp is plenty for a offroad Ea82 Link to comment Share on other sites More sharing options...
monkeyposeur Posted October 25, 2017 Share Posted October 25, 2017 (edited) No problem! If it is indeed a 22t turbo swapped car and the block is seized you could swap in an EJ205 shortblock from a USDM wrx, a JDM EJ20G shortblock, a JDM EJ20g longblock, and all could be run with the stock 22T ecu. To swap the turbo bits onto your 86 GL would require the oil return line mod I mentioned, running a coolant line and oil feed line to the turbo, a top mount intercooler or front mount, notching the engine crossmember for the turbo downpipe, a modified exhuast from the downpipe, a rising rate fuel pressure regulator, and only run 4-6 psi boost to be safe. Most turbo swaps like I just described work well in 90-94 first gen legacies, or some 95-96ish outback legacies or GCs.

sparkyboy Posted October 25, 2017 Author Share Posted October 25, 2017 (edited) 130 hp is plenty for a offroad Ea82 I completely agree with you, she is plenty quick and I have trouble getting traction as it is already. I can burnout well through second if I do it on purpose. Don't really want to mess with a good thing.The turbo would be a cool setup if i had another car to experiment on, maybe the car gods will show me some mercy in the form of an RX or GL coupe with a blown engine haha!
