Finally Drove my RB25/S13

[Chaos the Xile]

No lie, with that RB25 she's picky with that air flow get a Power FC that should be your next buy like soon b4 you go drving that car around too much and either lean it out or blow some stuff up! And then you'll be really PISSED!

Neutral position switch has to be hooked up. The reverse switch needs to be hooked up if you want reverse lights.

Neutral Position Switch has to either be hooked up or bypassed. The wire going to it needs to be grounded if you're not using it. I don't how your ECU didn't fry itself without that grounded.

Reverse switch is optional but suggested.

wait, you have an upgraded turbo on this motor but no form of management?im sorry man but thats just effin retarded and asking for trouble, stock computer and injectors dont take too well to an upgraded turbo with no management.you are proly hitting the airflow limiter which causes mad fuel dumpage and ignition retard, saying you had a larger turbo on there earlier would have helped too.

I was just going by what local RB people had told me. In hindsight, yes i figured i needed something but I was going on the information I had.

As far as compression and leakdown tests, those are being done on saturday. I took the turbo off last night and no oil was dripping from it. So right now we are looking at the valve seals or piston rings.

What? are you serious?

if you dont hook it up, your ECU will simply think you're in gear all the time, and your idle will be a little off, MAYBE your IAC wont be working right either but thats not gomer's problem. Please explain how this even has a remote chance of frying the ECU.

If you ground it, your ECU will think you're in neutral all the time, so it MIGHT affect your load maps but I highly doubt it.

Also while on topic of the Nismo FPR....where is a good place to order one from, since the car is down again I might as well pick one up.

yes it should be require that with a Walbro you got a FPR. Get one from http://www.performancenissanparts.com they ship fast and have good prices.

And yes if you are pushing more boost then stock (which with a bigger turbo you are) then you could be maxing injectors or the MAF. Find someone with the Nissan Consult and hook it up and see what MAF readings you get , and the duty cycle on those injectors...

Perhaps I overstepped my bounds here. I did a KA24DE swap into a 510 and the car wouldn't start and the ECu was throwing a bunch of codes until I bypassed the Neutral Position Switch. After looking at the foldout for the KA I found that even though i wasn't using the NPS I still had to ground the wire going to it as it acted as an ECu ground. I guess it's different on an RB. My bad.
