Hi, I recently bought my first skyline, Its a ECR33 GTS25T, in fact its my first car new enough to have fancy things like air con, and power steering. (My other car is a LH Torana) So I have found myself a little confused about all the fancy things in my new car. After a bit of playing i have mastered the power windows, mirrors, air con, and the other little gadgets, now its time I move onto the things that make the car ZOOM! First of all is the turbo, it has a HKS GT2540 Turbo kit. Now for me that sounds fancy but other than that I cant tell you anything, all I can find on the net about it is prices, how can i find specs/instructions or any info for this turbo?

I also have a GReedy B-Spec boost controller, Like the turbo it also sounds fancy, and it has a button that turns it from crazy mode into CRAZY mode. But how can i tell if this is set up right for the turbo/car? Or should i just be safe and leave it in crazy mode and forget about CRAZY all together?

Also if theres anything else I might have missed, or you think i should know about please let me know, as I really have no idea about the car at all.

Heres some other fancy gadgets it came with.

  • HKS GT2540 TURBO KIT
  • NIGHT PAGER DUMP/SCREAMER
  • GREDDY BSPEC BOOST CONTROLLER
  • GREDDY VSPL FMIC AND 19 ROW OIL COOLER KIT
  • TOMEI FUEL PUMP
  • NISMO 555CC INJECTORS
  • TRUST E-MANAGE COMPUTER
  • SPLITFIRE COIL PACKS
  • ADJUSTABLE TEIN COIL OVERS
  • GREDDY TURBO TIMER
  • 3" TURBO BACK EXHAUST

That is just high and low boost. If it was setup right, and the guy you bought it from had the car tuned at a reputable place, I wouldn't give anyone money to start fiddling with it. If its making power and not knocking, why burn money.

Nice turbo too, very responsive piece of kit. Don't change anything on it. It looks like some big money and time has been put into it. Enjoy it and when you feel you need more, strap on a hypergear.

+1 take it to a reputable shop and have them give it the once over.

Have them run it up on the dyno to make sure its all running safe.

Then enjoy what youve got :) (dont listen to anyone telling you your turbo isnt the greatest one.... just enjoy what it is for now as im sure its great).

isnt a 2540 like old tech HKS...??

shouldnt it be 'when you want some more bolt on a garret or a larger HKS'

Why? The turbo's that Tao has been working on recently really has sunk its claws into the top market turbos. Sure garretts are good, but they are generic turbos for any car; no specific application. These hypergear turbos are designed, built, and tested for RB motors. I know where I am(and have) putting my money. No dicking around with spacers, custom dumps, wastegate setups etc.

Take it to a reputable workshop and get them to give it a once over.

+1.

If I were you I would go and get it serviced; you never know what oils the previous owner was using or how long they have been in there, etc. Might as well get them to check general things like boost controller settings, and all that. Won't cost much, and for the peace of mind it would be worth it.

I got quoted $900 for a full once over, $1500 if I wanted my timing belt changed too and $1900 if I wanted my injectors cleaned. Told them to stick it. I changed all fluids my self, flushed radiator etc all round then had the car on a dyno. They told me the power, tweaked my power fc and told me it was safe to go. $90 spent on the dyno run and tweak.

When you move to Skylines, there are alot of things you can DIY to save money to pay for things you can't DIY!

HKS turbo kits are designed for their application as well, but they have been doing it a hell of alot longer and known to produce responsive setups with no 'dicking' around...

I dont believe there is any 'the best' setup, its what works all feels good to the owner unless your in comp...

but to say "Nice turbo too, very responsive piece of kit. Don't change anything on it. and when you feel you need more, strap on a hypergear."

Ive read, no, its not a responsive turbo compared to other HKS', and strapping on a hypergear is just one of many options, not 'the' option...

Lol at $400 for injector cleaning. The other stuff is ridiculous as well. Sounds like the workshop was trying to take advantage of you.

I do agree, I DIY most things on my car. But judging by the OP's post, he doesn't have much experience with these cars/engines. In my opinion, he should get it serviced properly and well checkout out the first time. There's a lot that could need changing that he might look over if just changing the oil, ie. belts, brake pads, rotors, etc. etc.

Then once he has had the car for awhile and has got some more experience with it, DIY to his hearts content :)

Yep without a doubt - take it to a workshop that you intend to use moving forward.

Get them to check it out. First thing i would do with a new purchase that has modifications.

Also a full oil change (diff/gearbox as well), always a good idea as you never know the last time it was actually done by the previous owner etc.

Yes totally correct. The HKS2540 is a old tech turbo unfortunately. Much better choices on the market now for 4-5 years

Certainly the first place to start if more power is wanted.

You will be surprised. :D

    • @Haggerty you still haven't answered my question.  Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are.  This process would be a lot quicker to figure out if we can remove user error from the equation. 
    • If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.
    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.
