Been good reading guys, thanks.

If i hit 250 with a nice fat curve thru the middle, I'll be pretty damn happy :)

Just so you know, it'll be :

Z32

s15 injectors, 450cc

Tomei Fuel Pump

Power FC

FMIC

Zorst/Pod

I'll post it up soon enough....

  • 3 weeks later...

So the GTRS is the GT2535?... Is this the most popular street turbo for the rb25det, How much is it?

I have a:

Apexi power FC

E-boost

Apexi turbo timer

3" exhaust from turbo back

Front mount intercooler with custom piping

Custom cold air intake

Custom intake plenum

80mm throttle body

post-28112-1179133304_thumb.jpg

Im getting injectors the same time as the turbo as they are maxed out now.

Will i need the Z32 afm or will it be ok?

Would it be wise to get an aftermarket exhaust manifold? if so top mount or low mount?

Will the set up i have reach around the 250kw atw.

Thanks mate much appreciated. Slowly getting there.

Does the GTRS have a T3 flange? I was doing some searching on horsepowerinabox and from what i can figure they reckon the GTRS is for the sr20det's and the GT3076 would be better for the rb25det's?

The GT3037/3076 is an exceptional turbo for its HP range. It features a .6 surge slotted comp cover and a complimenting turbine/comp wheel ratio, making it a great bolt on upgrade for the 2-3 litre range engine.

This unit has a lot of flexibility in offered houisings. It can be supplied with a T25 .86 internal housing, a T3 .63 or .82 external gate housing and a recent edition is the option of internal gate T3 in .63 or .82 (these units are more expensive and subject to availability at the time). Usual ultra reliability and superb response from the Garrett ball bearing design.

Great upgrade for RB20/25s and other 2.5-3 litre's looking for some serious power.

The GTRS is NOT the GT2535. But due to the very similar power delivery, HKS dropped the GT2535 once the GTRS was released.

Are you claiming to have 250rwkw with those mods, on the std turbo? If so go to another tunner, as he is pullin' your chain :P

On the other hand; Very neat and clean engine bay, looks awesome :)

The GTRS is rated at approx. 380hp

The GT3076 is rated at 500hp

Two totally different turbos with different power curves. The GT3076 is also a great turbo, but will be laggier than a GTRS, on an rb25. In fact i have just purchased the GT3076 to replace my GTRS, as i am doing an RB30 coversion and the GTRS would have been too small and would have resticted the engine.

Oh, and why are you gettin ganother one?

Wouldn't you just rebuild the one you have? or is that what you mean?

I lost my dyno (it was 339hp but whos counting), but supporting mods were

FMIC

Fuel Pump

S-AFC-II

Split dump, 3.5" front pipe, 3.5" de-cat, 3.5" exhaust

16psi on EBC

I sold that one, i got pissed off with spending $$ on car, but now i got the bug again and bought a trusted/renowned great turbo :D

That said, I'll have this new one installed soon so I can post a dyno then :)

he is asking once he gets the turbo and injectors done could he expect 250rkw out of the new set up.

Nahh i got around 200rwkw now but i ment when i get the mods will i have around 250 like fEkuaR said.

So what are u doing with your GTRS? selling :laugh:

The GTRS is a fair bit more powerful than the GT2535 hey.

Do they both spool up in roughly the same time?

Also can u get the GTRS externally gated as apose to internally? http://www.slidingperformance.com/catalog/...products_id=312

Pro's and con's?..........

There is a fair bit of info about the GTRS if you look around.

the best description I've heard is 'It has the response of a HKS2530 with the top end power of a HKS2540'

HKS2530 - supposed ot have ripper spool up as it;s quite small so you can't argue with that, but the top end, boost would drop off off as it choked and can't cope or whatever.

HKS2540 - Ripper top end but an absolute dog for lag etc.....only suitable for drags...

So combine the 2 and you have the GTRS

So, can we now keep this thread to be HKS2535 oriented?

Thanks peeps....

Sorry, my bad.

Am selling, but already have 2 potential buyers.

Since the turbo is less than 5,000 km old, i do not intend to give it away :P

  • 4 months later...

HKS 2535 is now tuned up to my satisfaction and it's a wee rippa.

Made 245.9rwkws on The Hitman's dyno which i don't think is a happy-reading dyno.

See the results in the dyno thread.

Spools up nicely and sounds great.

Vote 1 for HKS2535

And another vote for the s15 injectors which have done the job easily with more room to move(currently hitting about 80%)

I'm now guessing these babies are good for 270-280 rwkws.

That's it, anymore mods will be more along the lines of sell and by a Mitsubishi Mirage...tehe (seriously)

But I'm going to enjoy this one for awhile yet

Cheers guys :P

    • Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.
    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it. 
    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
    • I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option
