Hi all.

Im new to these forums but not new to skylines. Need some opinions and all are welcome.

I have a 1989 R32 GTS-T Skyline which was stock when I bought her from John at www.gtr.com.au.

Since I got her, i* dropped the auto out and got a front cut manual, and converted it (kept the manual computer). Upgraded the exhaust to a 3" from dump pipe, 3" cat and 3" to back of the car, put a big front mount cooler on and a r33 turbo keeping the R32 Waste Gate. I put a Walbro fuel pump and bigger filters on the lines to give her plenty of petrol.

I got a dyno done on the weekend and came up with a weird 167rwkws or 201bhp. It was 32deg on the day, on a main line dyno. It was still running rich at 16psi which I thought was very weird for stock injectors.

I was told by the guys at the dyno my car was running way to rich.. and to get some sort of tuning solution, be it a PowerFC or Nistune. I bought nistune and got it up and running last night.

Couple of questions:

Do you guys think 167RWKW for my mods is expected or quite low? Some guys post same HP with nowhere near the mods I have. (197bhp was aquired off a stock Rb20 with cat back and intercooler @9PSI stock everything else.)

Is 16PSI way to much for a R33 Turbo on a RB20?

Should I continue to tune the car at this level or drop it back to lower boost?

Could my stock injectors with that fuel pump really still make the car run RICH at 16psi of r33 turbo?

Any and all opinions welcomed before I take it to a tuner on the weekend.

* By I , I mean that 2 people helped or did the work for me in regards to labour.

      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.

      Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
