Hey all, Ive had my 93' 33 gtst now for about 2 n half years n its boring me. Ive been waiting for the time n cash to do it up a bit, now i have it(soon).Would this be suitable: 600hp+ turbo, new h/d clutch, f/m cooler, microtech ecu, bigger fuel pump n bigger injectors. What size injectors n pump are suitable? Is there something else i need? Ive got a 3.5" exhuast right through already n thats it, the rest is stock. Ive been out of the scene for a while n need updating if im missing somthing people are putting on to theres these days. This is n still will be daily driver.

Cheers for the feedback.

turbo is too big IMO for stock internals. also wont come on boost until probably 5000 RPM.

biggest turbo I would recommend would be GT35 rated at 500HP, even then would probably be too laggy for a street car.

ok then, apparently this particular turbo i was "gunna" get was an 'ATR45', i dont know anyhting about them or heard of it. Ive been told it was rated at .70 - 600+ hp. It is going to be dyno tuned so wouldnt they be able to do somthing about that then?

How much approx is a gt35 turbo n piping going for?

sorry, you said that would be too laggy aswell. Can any1 gimi as yell on a good turbo n housing (not piping) for me. I want somthing that is going to be strong n powerful that will be worth getting for the other mods im getting

not much you can do to tune it to hit boost earlier.. advance the timing a lil maybe but it can be risky..

that kit looking at $3.5k+

hks gt-rs mate.. or just go hi flow if you want to save a bit for somethings special..

Hope im not sounding too dumb but id like the car to boost up still about wot the stock one does. The hks would do that would it?

Go for a HKS GT-RS or a Garrett GT2860RS (Disco Potato) for a quick street RB25, thats what id do anyway.

You will lose a little bit of low down response, but gain loads of midrange and top end.

Or if you want even more lowdown response, but a bit less top end, just mod and high-flow your current turbo like whistle said.

Have a look in the RB25 dyno thread, thats the best way to work out what you are likley to need to suit ur needs.

Hi there.

I notice your new to the forum.

If you read the Dyno Sticky thread at the top of this section, you'll see results from many various turbo setups.

Golden rule is - more power you want, more lag you get. A 600HP turbo is never going to come on even remotely close to a stock turbo, yuor talking 4500rpm or there abouts

Have a read of the sticky thread, and also the FI Guide (just below it), once you see a setup you like with a turbo that seems to fit what you want, have another search with that turbo. Plenty of threads detailing HKS GT-RS, Garrettt 3071/3076, Trust TD06/TD05 series and so on.

Thanks

    • And if you want more power, more reliably, and cheaper, go get the Aussie RB... The 4L Barra and put that in instead.
    • No cats will keep discolouring the rear bar. Sends white paint a weird yellow stain. Cut and polish normally gets it out, but you'll be doing that every fortnight I found.
    • Both heads will be equally reliable or unreliable depending on what you do to them.  Stock the RB26 head will flow more. You have access to the stock intake ITB manifold on the RB26 cheaply which flows really well(1000hp+).   Arguably more aftermarket support for RB26, though in Aus we love our RB30 SOHC heads too.    The only downsides to the RB26 head is if you have a VL commodore and want to keep the SOHC look.  Where you may have an issue is drilling out the rb30 block for the bigger head studs but if you are building a big power motor you'd probably put bigger studs on the SOHC head too.  This is just about finding a good machine shop, sometimes easier said than done.  RB30 head worked can make big power just like a Rb26 head, so really it actually more comes down to what your preference is for your car.  People now even making billet versions of both.
    • 2630s work perfectly well. There is something to be said for just using the 30 head, as it saves all the pain of the conversion, still makes tons of power, still sounds cool, etc etc. 2630 will obviously make more power again, but the differences are not stupidly big. It really depends on whether you're racing for sheep stations or not. If it's dead serious, then it's a 26 head. If it's just for fun, it could go either way. But the 26 head and the effort to get it set up, etc etc, is part of the fun.
    • I've been building a 26/30 for a few years now. I've had the head built with all the good stuff. I had a 32 gtr but blew it up and yes its all going into a vl but im looking for some advice from some RB nuts on pros and cons on putting a 26 head on a 30 bottom end is it worth it Works are as follows Head -Extensive porting 1mm oversized supertech valves Supertech double springs Supertech valve guides Supertech titanium retainers Tomei solid lifters Tomei 270 x 10.25 cams Head drain Bottom end series 2 rb30 block Cp ceramic coated pistons Eagle rods Romac balancer Oil restrictions  O ringed blah blah spent a fortune And will get a girdle because the 30s arent used to handling that much rpm Nitto billet oil pump Hypertune plenum 6boost mani Refurbed astra pump thats the cover for it in the boot I did have a precision 6262 but sold it because drag car life. Currently building the ass end full 4 link floater rear end with a 2 speed  But the dilemma i have is my mate rekens I should just stick with the 30 head for reliability. Has any one had any issues with mounting the 26 head ie compression blowing gaskets etc. Just looking for some advice from people who have gone down this route. Here's some photos. Blew the oil pump in the gtr and decided to rip the motor out at the time and do a full build only to find it had been a repairable write off so went down this path.
