Considerations...?

[Az_StrYdeR]

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!

[Az_StrYdeR]

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??

[PHaT MR30]

no it was just typical jap.. rich!

[CATKICKER]

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

[Az_StrYdeR]

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.

Go the HKS 2835 Pro's. Currently running this turbo kit. it made 260rwkw on 15psi. I could of gone more, but didn't want to push the standard bottom end. 555 injectors will do the job.

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?

[Az_StrYdeR]

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 lol)

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

[dazzav87]

hey madaz how much did ur setup cost, just lookin at similr setup and just wondering what cost would be

[TAS_SINFUL]

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

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
