2530 here. Making around the 200rwkw mark @ 1 bar.

Mods in my sig.

My brother put a T04 on his 32 and is running a powerfc. Over 300rwhp. But when i drove it i noticed that 1st doesn't really boost at all and 2nd isn't much better. 3rd gear hang on lol.

I'm lookin to update my turbo .. but i'm in two minds ..actually 3 minds on which one to select..

Help me out.

(sorry for hijacking thread a little)

HKS 2530

or

Garrett GT28R

or

Garrett GT RS (GT28RS) i think

i'm lookin to run 1.2bar ..and produce around 240rwkw

Are these capable of this? with injectors, ecu, fuel pump, cooler and cams?

thanks

Matt

mm2death- how hard does your r32 pull, what is your redline and when does boost come on? thanks in advance.

Yeah goes great. I've made a few people shit themselves...lol. But like with everything, you get used to it and then after no time at all you wanna go faster :D

Redline is about 8...not totally sure as i always shift at 7 the most. Boost hits fully at around 3500.

Cheers,

Scott

Hmmm, this thread is interesting

I have always thought my turbo was a HKS GT2510. Due to the CHRA tag being un-helpful (no numbers that meant much) I have always taken the sellers (JMS) and the installers ( Tilbrooks ) word for it. Also has a HKS 1bar acuator (although it only gets it to 0.9bar :) ) and also has a cast HKS dump pipe

It bolts on, and is definatley a HKS 25 series from the housings etc, but looking a MM2deaths post, how you say full boost is at 3500rpm, I am now thinking differant

Mine makes 200rwkw at 0.9 bar, and full boost is from about 4500-4800rpm and pulls really well from there to the rev limit at 8200 rpm (re-mapped chip)

Any idea's? I am now thinking 2530 or 2535 perhaps?

from what i know the gt rs is an update of the 2540, similar and made  more responsive providing an extra 30 odd hp than the 2540 also.

i thought it was more closely related to the 2835 turbos. power between 2835 and 2835R, with slightly better response.

Hi guys, for what it’s worth, our RB20DET has a GCG ball bearing hi flow of the RB25DET standard turbo, makes 1 bar at 3,100 rpm, some boost at ~2,500 rpm (depending on load), has GTR cams, adj camshaft pulleys, std R33 GTR intercooler, split dump, no cat, 3.25” exhaust, Power FC with boost control kit, well tuned (not by me), 225rwkw at 6,900 rpm using 1.3 bar, power flattens over that but doesn’t drop off dramatically, revs to 8,250 rpm easily (needs shift light, badly).

The result is the sum of the parts, not just one single part. That means you won’t get a similar result (whether it is good or bad) just by choosing a turbo.

Hope that helps

Does the front look like this?

    • 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.
