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

Picture #2 is your absolute pressure sensor. When you go to the 95~97 ECU, you disconnect this sensor. You could go further and disconnect/cap the vacuum line where it runs to the vacuum gallery. That way you can remove it all together. Being that you're doing what I am, and removing the galleries too, you don't have to worry about capping anything off.

Secondly, I'm assuming that the DE throttle bodies use the same TPS, on all lowports. You could just yank the TB off of the manifold you pulled out, and put it on the other lowport manifold you have.

I thought that was the sensor cuz that was the only one conencted to the firewall. And I will deffinatly need some help when I go to put all this stuff back together haha. Think you could make a quick diagram of where all the lines go? Some of them are obivious, but I'm not sure on. If you could that'd be great if not then I'll just figure it out.

And what about the third picture? What do I do with it? cap on the 1 line I pulled and pull the EVAP Pressure? Line and cap that also?

You won't really have but three total lines when you remove all the crap I mentioned. One for the wastegate, one for the BOV, and one for the FPR.

haha ok thats awesome. once I get the manifold it should help me a little to figure it out, it should be here next week. Thanks for the help man!

Good luck! If you get it going before I finish mine, post up!

I will, but I'm still waiting to send my ecu out to calum all I gotta do right now is tap the block, and put everything back together

still need to do my ecu and a bunch of things to do but i got it on there test fitted. For the EVAP Service Port, do I just block that off? I think thats the only one I got left that i'm confused about.

Lookin' good! Sorry I just got back in from being out of town last night. I'll do some more reading today, but the EVAP service port isn't even used in the 95~97 ECU, so you could just yank it off and cap it. I'm actually reading the entire section again about the sensor in the rear, and trying to find out if I can just remove that solenoid that the service port connects to.

***if any of oyu guys doing this does not need this extra EGR let me know I'll buy it from you guys.
I need the complete Intake Manifold plus the 98 ECU. LMK.****

I've got a 98 ECU, a 98 Intake manifold complete with EGR/BPT/etc.

I'll let you know as soon as I get the car running. I'll let it go at a fairly reasonable price.
