i have a rb25det sII in my r32 gts. Yes it fits and yes the gearbox does fit but tailshaft will need to customised as will crossmember. No real issues that cant be overcome. Speedo cable needs to be modified or your speedo will be out.I'm also running the series 1 computer as according to my mech they allow for more tuning then the series 2. As for price, how can one answer that??? However much you can pickup all the parts for (for me, the engine + box was 3grand, engine at 45,000 clicks) plus however much someone is going to charge you for labor. I paid $600. Plus, then, depending on what state you are in you will need mod plates which if your in qld means bigger brakes which will cost you again. over all with brakes on mod plates it cost me roughly $4200 but i got engine and labor quite cheap through mates.

also, you dont neccessarily miss out on LSD. I'm not sure if its aftermarket or what but my car when imported came with LSD plus sun roof e.t.c that CAN possibly be upgraded on the gts. I think its a big myth that most options only come on gts-t. My gts came with upgraded seats, sunroof, blue dials, upgraded front bar, and nismo rims. These were all from factory.

      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.

      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.
