I recently put a JDM 2.0 DOHC into my XT. I swapped all electrical components but left the JDM cams on it. It runs just fine and the only code I get is for p1086(tumble generator sensor) but it definitely doesn't have the power I would expect. I ran diagnostics for timing while driving and the baseline is 17 and when I accelerate it jumps to 42.5 then continues to drop. I work on Subarus and have swapped plenty of non turbo jdms with great success but this is a little out of my league. Any help is greatly appreciated!

I recently bought an 04 Forester XT that needs an engine. I was hoping it didn't have the avls system but it does. I went ahead with the purchase because of the condition of the body. I was told I might be able to throw in an engine that doesn't have the avls (I feel like pre avls engines are way more reliable) and delete the code and you can run it just fine. Is this so?! If so, how? and if so again, what do you think the best engine would be to put in it. As for my situation, when I say "best" I mean most reliable. I'm excited to have a turbo, but I'm going to be driving this thing long distances and am more concerned with not breaking down over break neck speed. But speed is fun or I wouldn't have got a turbo! Thanks in advance.
