Just for research purposes, can anybody please tell me some info about the engine in the R31 GTS-X and what turbo they use ??

Are they the same set-up (turbo and engine) as the R32 or different ?? If different, then how ??

What are some good upgrades for the R31 GTS-X engine ??

More boost (do they have a boost cut, if so, what boost??), Filter, Exhaust BOV etc ??

What bolt-on turbo upgrades can you do on them ??

Would a chip to remove boost cut, speed cut etc be as simple to do as a R32 ??

Acceleration figures ??

Does anybody know of any good ones here on the forum that they have some info on.

red top rb eccs has smaller injectors, a nasty boost cut @ approx 13psi on std turbo and half that for a hiflow. and is harder to tune std ecu. im not sure about the nics red top in the early hr31's but apparently harder again to get power out off.

at the thread says. the r31 NICS and ECCS ECUs are chippable.

no one has figured out the NICS yet (i've had a look at it but haven't really spent much time going through it as i can't see any maps like on the ECCS units just random data)

the redtop ECCS versions contain the maps in the standard locations (similar to the RB20 silvertop). dr drift and myself have a stealth image from lowlux's which we can rechip.

probably advances the ignition timing and fuel maps against stock (i dont have a stock R31 ECCS image to compare against yet so see what they changed). the rev and speed limiters are easy to adjust in romeditor but boost cut i dont know much about altering yet

      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.
