Well, I blew the rear wheel on my turbo over the weekend.

I have a replacement coming to get the car running again, but now I'm considering upgrading it.

Atm I'm thinking HKS GT-RS.

Just wondering what you guys think??

I have all the supporting mods, bar Z32 and injectors (they will be on the list if I go down this path)

Hey Man, so sorry to see that happen!

Was waiting for this post though :lol:

I think you should go for it, but it isn't coming out of my pocket.

It is such a clean car man and if the flutter comming off has been your biggest problem, you are doing pretty well! :)

P.S. I just put a stock ECU in (was mines) and it is a completly different car... I am loving it! Can't wait for more than 350kms from a tank! :down:

Yeah I was pretty cut lol, not in the fact that I didnt think it could happen, was just really looking forward to the drive home!!

What do you reckon 555cc or 740cc??

Thats awesome about the improvement of the ecu change over!! Do you reckon it was tuned for a bigger turbo??

that phat man is almost right... i think it was more so confused, pinging it's head off, tuned for higher octane fuel etc!

glad that is gone and I have been driving it like a softy in that time since it was running so poorly!

can't really help you on the injector size, Sam will be able to assist there... have you decided what you are going to do?

well what about looking into a hks 2530 or even 2535 they good turbo fast spool up on the rb25 they are an old style type of turbo but it depends what are you are gaining for in power out put, as for injector upgraid i would think to be on the safe side go for 720cc sards for that matter but do also if you have not allready done so upgrade the fuel pump and maybe also power fc never go a stray something to also think about

Thanks for the input Mich, know where you can get one of those kits?? and costs?

As part of the normal mod's before looking at the turbo upgrade I have fuel pump and powerfc. Was trying to get as much as I could out of the standard turbo, but since having lost the rear wheel out the exhaust, I have lost faith in their ability LOL

Sam's said the 555's will be more than enough for the power.

thought i mite give u my 2c on injector size, I have a standard RB25det, Z32 afm, pwr fc, Vg30 hi flo 040 fuel pump, and went for the 555cc injectors, runs 15lbs all day every day, has 250rwkw, this is not pushing the limits, 555cc handle the job nicely with more room to move if need be. was going to go bigger but not needed, what are u looking at kicking out power wise?

Well I have looked at the 2835 ProS Woolls, but I cant justify the extra cost for it, when I should be able to get that sort of power fron the GT-RS. Even if its a little less power I'm not going to be worried.

I dont intend to open the engine up and rebuild it, so I'm not going to get the most out of the 2835 (but I wasnt intending to upgrade the turbo either :D lol)

Im hoping that I can get some where around 250kw, but I really after a solid, responsive setup. We'll see what happens!

hey stryder, for what its worth imo for 250kws going all out on gt-rs would be delightful, if you have deep pockets :cool:

i however don't so a cheaper but still far capable option would be T517z's with 8cm rear housing to suit your quick spooling lust. also available in the 10cm rear too which is not a "laggy" turbo by any means.

if you were going to go nismo 555 you may find the price between them and sard 720 perilously close..just another something for you to consider i guess.

what is your car doing at the moment fuel pump wise.?

best of luck anyway dude :rofl:

    • Should be more than fine, especially the overall fuel pressure would never exceed 3.5bar (assuming that thing never gets more than 0.5bar of boost in stock form). According to the chart, it's 11amps.
    • I definitely know the first rule here, look first, ask second. I've seen many people get roasted 😂 I found a few diagrams for the RB, but I'm yet to come across one for the VQ. From what I have read, the pump gets the +12v along with the FPCM, and it's the negative wire that gets passed through the resistor to regulate the voltage. So I assume I can just ground the negative wire at the pump to eliminate the FPCM control. But I really wanted to see the VQ circuit diagram first to make sure I understood it correctly. Once the new pump is in I'll do some testing to see how it behaves, and in the meantime, I'll keep looking for a wiring diagram. Thanks for your help mate, your time is greatly appreciated.    
    • Maybe? I have the Supercheap ToolPro low thingo. It has a somewhat smaller diameter lifting "bowl" than you would expect on a workshop grade trolley jack, and a split rubber pad to suit that diameter. It clears the "N1" style skirts I have. Probably wouldn't if the jack's bowl and a suitably larger rubber block were in use. Having said that though.....you only need the rubber block to exist on the inner side of the pinchweld, so could carve away any rubber that fouled the skirt, leaving some there for "insurance" </simples>
    • I used to do that (sills with rubber jack block).. ... then I got side skirts, and there's no way for the jack to actually work there, the jack pad itself on the jack is too big. Is the answer to use a... smaller (?) jack? Hmmm.
    • I have too much trauma from every skyline I've ever seen having crushed jack points/pinch welds lol.    Yep, works 100%, it's what I use when I'm using the quick jack. Don't know why I can't also bring myself to do the same thing when I'm using a jack. I blame the skyline PTSD.
