Hey all, im looking at getting a hks gt-rs turbo for my car along with injectors, fuel rail, pump and already got a pwr fc and exhaust and cooler. Does anyone know much about the gt-rs, all i know is that its good for 400hp(im aiming for 360) or does anyone already have one and do they like it, just want some feedback on the turbo, like if it bolts straight on and what rpm im it spools at etc.

Thanx guys.

Just my car retuned today with a Z32 air flow meter and got 270rwkw. I think a GTRS would be hard to beat for response and power, it reached 15psi at 3400rpm and 17psi at 3800rpm and is set to 1.2bar. The HKS turbo kit does bolt straight on comes with wastgate and all lines.

Z32 definitely worth getting gives the tuner heap better resolution so both 1.2 and 0.9 bar are heaps better, 0.9 bar almost feels like the power I had at 1.2bar before without the Z32.

Other mods are full 3 inch exshaust, FMIC, PFC and boost kit, nismo 555cc injector, exhaust cam, lightened flywheel and ceramic clutch, spitfire coils and bosch 044 fuel pump.

Thats a sweet out come reedy, what else you got done to da motor?

I'm also keen to know what other mods have been done...

I'm contemplating upgrading my turbo in around 12 months time and just want to make sure I make all the other necessary mods in the mean time to ensure that I can get the best of my new turbo once I decide on which kit to get. I was originally thinking of going down the gcg hi-flow path (aiming for 240-250rwkw), but your results are pretty impressive and kinda justify spending the extra money on getting the GT-RS.

What I'd be interested to know is:

1. Do you need a catch can at this power level?

2. What fuel pumps are people using to get there? I have one of those Walbro 255 thingos but now I'm not sure if I should use it. Surely a surge tank is unnecessary?

3. Is everybody using a pfc? I am thinking piggy back but I have an advantage in that my ecu has previously been tuned (read chipped) so the mid range dip is gone as are the limiters such as speed cut.

The only other mods are suspension but in more detail i've got;

-Full 3 inch exhaust with high pressure coated dump, magnaflow twin tip.

-Front mount intercooler 600x300x70 tube and fin core

-Bosch 044 fuel pump

-Spitfire ignition coils

-Power FC and boost kit

-Adjustable exhaust cam gear

-Nismo 555cc injectors

-HKS GT-RS turbo kit

-Xtreme billet lightened flywheel

-UAS sports clutch kit

-Tein super street coilovers

-Whiteline front and rear swaybars

-JIC tension rods, front negative upper link, rear adjustable upper link

I think its worth spending the extra money on the gtrs rather than a high flow cost about $3000 with shipping and got $300 back for old turbo and you get new turbo external wastegate and oil lines.

    • For race cars, this is one part where I find having the roll cage bar having gone through a hole in the floor better than the build it up on a ledge inside... The Merc I help on, the main hoop ends are marked on the car, and the jack is marked... Jack goes under a few inches and lifts one whole side of the car up... Removes that fight for long slim jacks for race car duties!   My biggest issue for the daily drivers I work on, is my jacks don't go high enough. The jacks start out on a few blocks, jack it up, then start a second jack under it on more blocks, and then I can get an axle stand under it. My axle stands are presently in use, and are nearly fully extended. The car is sitting with barely more than a cm of clearance to get the wheel off the studs! Sarah's Kluger is the same, as it has an ungodly amount of droop available in the suspension and a distinct lack of good jacking points!
    • Happy? Yep, my to do list is getting shorter and shorter. Either this light approaching is the end of the tunnel, or I'm about to be hit by a train... Ha ha ha   Also, Duncan isn't that far out of town that you need to make a multi day drive out of it. 😛
    • Sorry I meant that we are building the EH for a client.
    • LOL, when one "money pit" is never enough Noice, and excellent work mate
    • I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed
