Thread: 98+ SR20DE vacuum removal (to 95~97 standards)

Yeah, i'll try to follow that tomorrow. I got some of the stuff off. Seems pretty simple the way you just put it And what about the lower half of the manifold? Is it the same between the 95-97 and 98-99? Cuz it looks like a real PITA to take off lol

Yeah, it's the same. The only difference is the upper manifold itself.

Sweet, really didn't wanna take that off hahaha. Thanks for the help man.

They certainly don't do that in Texas though. Not in Oregon or Washington either. I might do this if I can learn it all. I'm willing to bet that these items cause the stuttering I referred to earlier. No common tune-up item is known to address it and its only 98/99s.

My ECU doesn't need any of that crap! AEM EMS FTW! LOL~

Great thread Tekkie. I wish I could add something but when I Boosted my 98 I went with a DET swap. I had a CEL and a bunch of unused plugs but the car ran great.

No Emissions testing in NH back in the day so I didn't care to hunt down all the codes or anything

Ok, this is what I have pulled so far.



I noticed I'm missing the white T, I thought I had it somewhere, but now I'm not sure if it was even on the car.... where does that lead to? And what do you do with the part that goes into the intake (the little nipple line)?

Second, what do I do with this? I'm not sure...



And third, should I take that line with the evap port off?

Well the seccond one looks like the charcoal canister most people leave that because it helps with evaporative emissions and isn't leak prone. I had mine disonnected on my B13 for awhile and it didn't seem to hurt things.

I have no picture of a charcoal canister up there lol the third one leads to the evap canister in the back of the car, that second one says something about Boost on it lol

Oh and also tekkie, what about our throttle bodies? We have 2 connectors on it for the tps, do we need to switch to the other style?
