FWD sr20de throttle body on rwd sr20det

[LoSt180]

Yes, old thread. BUT this thread keeps turning up in my searches for installing cruise control in my S14 SR. Figure I can provide a small update. My apologies if this is already common knowledge.

The P11 (99-02) G20 throttle body bolts up, and the throttle position sensor can be swapped over without an modifications. The S14 TPS wiring also plugs into the top connector if you don't want to switch sensors around. The bottom one is for auto trans WOT/Closed switches, leave unplugged.


Here are some pics of a 99 G20 throttle body and my S14 SR20DET throttle body:

P11 left, S14 Right.



S14 left, P11 right. Essentially identical.



P11 left, S14 right. TPS sensors. Use top plug on P11 for a true PnP affair.



Cleaned up P11 TB with S14 TPS installed. Need to fabricate a cable bracket since nothing really lines up anymore. Too bad the OPs pics don't work.



Installed. On S14 the left coolant line comes strait out, but there's enough hose to connect to P11. It has one vacuum port, the S14 TB has 2, but one is plugged anyway.



Hope this helps future searchers.

Hey man I was running the same p11 tb on my redtop for a few months but then I noticed the throttle body seals leaking under boost. I swapped back to a different stock s13 sr tb and it's never been an issue since.
I have 2 theories either the p11 have different seals that don't hold boost as well or being that I live in Arizona I feel the seals could
Also be old and dried out. Especially since I got my throttle body from a junkyard out here who knows how long it was exposed to the az heat.

Thanks for the heads up. Something I will pay attention to when I get this installed.

For sure. I was chasing that leak forever. And honestly I feel it's more likey crusty dried out seals than anything but just figured id offer it up.
