Selfproclaimednerd Posted July 21, 2011 Share Posted July 21, 2011 I have a 92 Subaru legacy 4cl turbo with 180,000 miles. I’m in no way an automotive expert but I have a couple of friends with car knowledge but not with my specific car. I am wondering how I might get the most power out of my engine. Does anyone know the capabilities of this motor as far as how much boost I can push into it Stock with no modification. For example: a bigger turbo/ exhaust/ up the boost and tuning. Basically what I’m wonder if my engine can handle these upgrades. Or if there is even a point in trying… or if I should do an overhaul. So basically, three questions Can I turn up the boost stock (and be happy with the power output) without having the motor explode? Do I need bigger turbo/exhaust n all that jazz? Will the motor even hold? Link to comment Share on other sites More sharing options...
Baddog Posted July 21, 2011 Share Posted July 21, 2011 The EJ22T (The motor you have) is a pretty stout motor. People put on WRX Top mounts, 440cc injectors, TD04 (WRX turbo), Master Boost Controller and a full exhaust and make 170-200WHP. Which is pretty fun.

Legacy Wagon Posted July 21, 2011 Share Posted July 21, 2011 I'd just be worried about the engine at that point. That's a lot of miles to be trying that stuff now. Link to comment Share on other sites More sharing options...
MoparPhoenix Posted July 22, 2011 Share Posted July 22, 2011 I was under the impression these engines were extremely tough? I was planning on doing performance mods on my '92. We were planning on rebuilding it & then strapping on some fun toys. (sounds so dirty, lol) I hear 02-04 WRX's are good donors for upgrades.

Legacy Wagon Posted July 22, 2011 Share Posted July 22, 2011 They are...but any engine that has almost 200,000 miles on it isnt a good candidate for upgrades in my opinion. If you went through and replaced all of the seals, the oil pump, water pump...well...most things, then it'd be a different story. I'm just cautious about beating on an old engine.

Bdubs Posted July 22, 2011 Share Posted July 22, 2011 Don't turn up the stock boost without any upgrades. It's set that way for a reason. The cheapest, less lethal upgrades to the engine would be a TD04 swap w/ Intercooler, Manual boost controller, boost gauge, turbo back exhaust. You can get all this stuff used and whatnot on NASIOC or craigslist. Most time consuming would be turbo swap. You have to custom make all the tubing to fit the Intercooler to the turbo, make sure it's all air tight, everything aligns properly. All while making sure you don't break anything brittle on a 20 year old engine bay. Also bbs.legacycentral.org has a ton of info regarding swaps, anything 1st gen. related as far as specific parts needs. Link to comment Share on other sites More sharing options...
Liberty10 Posted July 26, 2011 Share Posted July 26, 2011 http://bbs.legacycentral.org/ (that's the link that worked for me, not the first one) Thank you for the info! I was wondering how to figure out what's compatible and what wasn't - not that I'll be adding much more than a sun visor this year.. lol Link to comment Share on other sites More sharing options...
