hi there,i want to run a big single turbo on my GTR,first question is running a big turbo on a gtr is it required that i rebuild the motor,or maybe the question is whats the biggest turbo i can run on a standard motor,im not opening the motor yet apart from HKS step 2 cams and gears.i do understand its not going to get much boost in a standard motor,but i want to see what i can make without opening the bottom end.the cams will help with high cylinder pressures

i have a T88-34D and can also get a GT45.and iv heard i can get a TO4Z

i know what the first question will be and yes i dont care about lag,there will be heaps and i know,i use to own and pilot a 7 second rx3,so i know what it takes to drive something like this.

im not new to GTRs but have always just been a sheep and run small singles.i want big.

any and all advise is greatly appreciated .

You can make any figure, how long will it last though?

If you want it to last - GT35, about as big as you can push a stock bottom end reliably.

Otherwise, if you have the money there for the rebuild, boost away with whatever your wallet can afford

Big turbos... which make big power... and stock bottom ends, don't last. So no point having a big turbo if your not chasing big power

Im running a t04z on my GTR and it goes good. After a few problems with fuel delivery i've now got 337awkw's at 14psi. Stock bottom end with 260 Tomei poncams , Vipec ecu and supporting mods.

It is abit laggy, fullboost is at 4500rpm which isnt too bad, considering the n1 turbos i was running before was 4000rpm.

But im not going to be running anymore boost until i rebuild the engine as it simply wont last.

i just spoke to my machanic and he sugested the to4z.he said 350-375 kws....

im also looking at a GT45,the machanic has a R33 GTR with one of these big boys on it,runs 18psi and make over 650hp.

yes the bottom end is done but it was metioned that it was driveing on 12psi for 12 months making 510hp all day everyday before the bottom end rebuid.

350-370rwkw is right in the meat for GT35 territory mate :nyaanyaa:

a T04Z will run off 440rwkw, so unless your looking for that...

There is a big thread on GT35/T04Z going at the moment with lots of information for either side so you can make your own call there

      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.

      Automatic Power Button Light Flashing

      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.
