Thanks Jessie. I appreciate the good work. 👍

Man Subaru people can be so uptight. You helped someone with info to do this swap into my LGT and it’s a great engine. People hate this swap and I don’t know why ..it’s a better engine and the ej255 is crap. Across the board it just falls apart constantly so idk why everyone hates this swap so much … I’m glad to see people like you with good credibility giving these swaps some justice. People swap Hondas all day and it’s no issue but with Subarus people just love to judge 😂 thanks for doing the car community a favour.

Extremely valuable video, thank you! Question, to avoid any issues later with tuning, have you swapped the exhaust side cams and camshafts to non avcs components? This is also factoring in doing valve clearance corrections with the new cams etc. would this be a better option than manually advancing the avcs exhaust cams?

@TheSubieSanctuary

4 ай бұрын

I personally have not done that. Yes if you swapped 255 exh cam shafts and gears it would leave you with correct exh timing. Youll need a non avcs cam seal. As for the solenoid and stopping or restricting its oil flow. That part is slightly unknown to me. Ive heard of people removing the valve and plugging the in and out oil holes. But cant confirm function or safety

Or buy a twinscroll downpipe if you dont want to weld the oem twinscroll downpipe cut off to your current downpipe. Have the twinscroll stuff on my personal car and i love the instant turbo response

Then you would use the 02 wrx intake manifold and harness, plus you will have to add the cam sensor on front driver side of the 257. There will be a hole there for it with some rubber.

Because the 20X has variable exhaust timing, wouldn’t it be able to advance or retard with oil pressure changes, even after setting the timing back one tooth? I’m just not clear on what that ~14 degree retard (I believe) accomplishes if the AVCS lets it still actuate.

@TheSubieSanctuary

It can lightly and unnoticeably float but since the no power to the oil control solenoid, Its remains in the same phase all the time.
