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:

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
