hey guys i was really interested to know if anyone can double check for me if turbos from auto r33 gtst's are/look different to manua r33l gtst's?

i bought one and it looks like this.

now can someone tell me if this is an r32 gtst turbo or possibly an "auto r33 gtst" turbo.

i have heard this in a couple of cases where the auto r33 turbos look different to manuals but looks similar to r32 turbos but with bigger compressors or something along those lines? do series 1 or 2 matter also?

can anyone confirm?

fyi

the turbocharger on the auto and manual GTST (of the same model) is identical

ie nissan did not make different turbocharger models for auto and manual

they did, however, use a different actuator spring on the auto turbocharger

this is because the AUTO gtst runs less boost than manual from factory

from paulr33.com

ECR33 manual is 385mmhg which is 7.4446 psi

ECR33 auto is 270mmhg which is 5.220 psi

you can, if you can drill out the oil restrictor on the hollow screw and the benjo. not recommended.

Thats what I have done, been running fine for over 3 years. You just have to be careful of how much you drill into the banjo, as it doesnt like too much or too little oil, esp if its journal bearing.

@paulr33 I beg to differ about the boost levels between the r33 auto and manual. I drive a auto, and before I put a boost controller on, it was boosting to around 7psi in high boost mode. Which should be just over halfway on the stock gauge.

Says it all. High boost Mode would've had the stock solenoid hooked up which gives 2psi extra.

My car was auto from factory but converted to manual, boost was 5 & 7psi and 7psi with high boost mode.

      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.
