I have a turbo'd GSR. The swap was done for me by some friends who pulled the motor from the Tegra when I bought it. I've since been doing all the work and am currently redoing all of the little IC piping to upgrade my IC core and piping to 2.5" from beginning to end.

I have one sensor left unplugged and has been since I had the swap done. I've been told by several people it's the IAT sensor (intake air temperature?) and it's the reason my tuning on Hondata has been a little sketchy.

How important is it for this sensor to be plugged in? Can it be deleted? The car runs fine, pulls fine, and all without it plugged in, but I keep having people tell me to hook it up. Also, if it is needed, is there some sort of kit I can buy to have it mounted in my new IC piping?

Any advice is appreciated. Thanks a ton! Just want to make sure everything on my car is properly hooked up as it should be.

 

Why wouldn't you just put it back in its stock location in the manifold? Yes you need it for tuning properly. Otherwise its reading the temperature in the engine bay and not the intake charge

 

The sensor may not be a super-fast reaction type like an open-element GM sensor, but it still helps. When you tune, generally the IAT's are high, and the manifold gets heatsoaked. When you run WOT with a still-cold manifold or cruise with it heatsoaked (basicly any condition besides when you tuned), you'll be a little rich or lean.

It is a big deal if you have stock internals. GSR's may take a lot or power, but it takes very little detonation to shatter the ringlands. Run a little lean, and that will likely happen. Ideally it gets put into one of the runners, but you can also put it into the charge piping. OBD1 cars usually have it in runner #1 or the plennum, newer cars have it right before the throttle body.

 

It's a fully built GSR motor. Also, it has a Skunk2 Manifold, from what I'm told (it looks really similar to the stockers that I've seen on other B-series cars, but I'm not seeing a spot to plug that sensor into. I think I would notice because it's got boost so that would most likely be a rather large boost leak considering the size of the sensor's end. Also, I'm picking up a Golden Eagle Intake Manifold this weekend so, I'm assuming that won't have one either, that's why I was curious as to whether or not there is a kit to route this over into one of the intercooler pipes. I'm really at a loss and all I keep hearing is nagging from my turbo honda buddies about how it's not plugged in.

I know there are kits for N/A models where you just tap the intake pipe and push in rubber gromet that holds it in place, but I need something that can be pressurized. Sorry for all the noob questions, I'm just new to Honda's.

 

I tapped my pipe and used a rubber grommet. Been running this way for almost 5 years with no problems being pressurized up to 20psi. You just need to make sure its a tight fit.

 

Where did you buy the gromet? I could do that, if it works well, just need a direction to start looking.
