I think thats the thing, the three clutches i have had , std, UAS GTR ceramic puck clutch and anoe the Xtreme ceramic puck clutch are all light and not very grabby. So they will die / slip before putting too much shock loading through the box.

A friends misfortune of late has reminded me of what a mechanic told me, dont over clutch the car, as it will kill diffs and gearboxes:)

As for diff i run Castrol SAF-XA, 80w-140 (hopefully a link that works this time:))

id say the xtreme 9 puk ceramic clutch in my car was overkill. It was a xtremely (sorry :D) heavy and a biatch to use in the car park. It also was part of the reason my clutch pedal box split into 3 pieces, popping spot welds etc.

The OS giken twin plate in my car now is a more user friendly clutch, being no way near as heavy, and very nice in the car parks still.

As for the r33 box in the r32...ive gone through it before...but oh well : U need rb20 part of tailshaft that bolts it to diff, custom tailshaft, r33 box yoke, r32 gtr speedo sender, r33 red cog off electronic sender, custom gearbox x member.

Other than that it bolts up, and gearshift sits in the same spot as the rb20 box did.

      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.
