Hey guys. I recently put a 3inch dump pipe on my r32. After installing it i took it for a spin. It felt okay. Then i came to a stop and the car revved to 2k. I tried to accelerate but it wouldnt let me go above 2k. It stalled a few times also.

1 of the nuts that connect the dump to the turbo wasnt tightened all the way because i couldnt get to it. Can this be my problem?

No

If a bolt has come loose the worst case scenario will be an exhaust leal. As it is after the turbine there is no power loss from this. I'd expect noise and possibly a tiny tiny power gain from an exhaust leak post turbo if anything

Id say youve disturbed something while doing the dump pipe. Check all plugs and pipes in the area

just search your symptoms, i couldn't even begin to explain how many times this comes up.

 

it has nothing to do with your dump but something else you have affected as said.

i just put 2000 rpm into the search, here are 10 of the 1000 which came up.

if you want another 789674653 threads search afm or cas or missfire or limp mode ect

No one knows exactly what is wrong with your car. Stop obsessing about the dump - it is entirely possible that a fault has developed in your car that has nothing to do with your dump. Start reading some of the links that Glynn has kindly provided.

to simplify the subject, a 2000rmp issue is a redflag for very common issues with RB engines. it WILL be the usual suspects. these are very easy to check and fix. the same answers will have arisen in any thread with a 2000rpm missfire/ hesitation.

 

have a read in the threads about what they found how they found them and how they fixed it.

 

when i had the issue the solder inside the afm plug had deteriorated, going over bumps gave me my issue, they could have dried ages ago over time and you dislodged it when you took the dump off. check the plugs, maby resolder them... there is a link somewhere... i know i posted one when i hit the issue.

but there is nothing the dump can do within reason to cause the issue your having now. dont look for unicorns when you find horse poo,

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
