Hi there, I have an R33 with the usual mods, 3" zorst, FMIC, Haltech E6K, 12psi on standard turbo.

Im wanting to rebuild the turbo with GCG turbochargers,

Nissan GTS-T R32 & R33 Upgrade of Standard Turbocharger:-

The factory turbocharger is a ball bearing T3 sized unit with a ceramic turbine wheel. In upgrading this unit we replace the ball bearing pack with a new one while replacing the turbine wheel and compressor wheel with hi-flowed models. The upgrade comes in two stages.

XTRGTST-STG1 450hp rated $2250.00

XTRGTST-STG2 500hp rated $2450.00

Then im assuming a new fuel setup,

Fuel pump,

Injectors, what size would suit ? what are the standard size?

Any constructive comments would be dearly appreciated.

Thanks guys...

:uh-huh: :uh-huh:

u will need 550cc side feed injectors (hard to find) 600hp fuel pump, ebc to control boost properly, new clutch, z32 afm and if u want it to run rice i suggest u get lightened flywheel and adj cam gears, pineapples for the rear.

I am going the same thing and have bought about 75% of the parts for my upgrade

I am actually looking into the same highflow option through GCG.

However the info that I received from GCG is:

Thank you for your enquiry, we can do a high flow to your turbocharger but it is a little more involved than a standard turbocharger, this is due to the fact that your turbocharger is ball bearing and has a ceramic turbine shaft. The rebuild / hi flow we carry out to these unit are as follows:-

 

Turbine Wheel  - replaced and upgraded with a inconel(steel) wheel , either stage 1 or 2

Compressor Wheel - replaced and upgraded with T04 wheel, either stage 1 or 2

Bearing Pack - replace with an XTR ball bearing package

Turbine Housing - machine to accept either of the larger wheels

Compressor Housing - machined to accept either of the larger hi flow wheels

Wastegate Actuator - standard or upgradeable to have higher boost pressure as standard.

 

Costs - Stage 1 = $2250.00    Rated @ 400hp

       Stage 2 = $2450.00    Rated @ 450hp, does require other mods i.e. intercooler, fuel, etc

 

These prices are for the turbocharger only, but remembering that in effect the turbocharger centre will be brand new and the turbocharger will bolt straight back onto the engine with all fittings.

If you are going stage 1 then you can bolt it straight on without changing anything else however this will not perform to its maximum efficiency. If you are going for stage 2 then you need to do fuel, fmic, computers, etc

The standard size are 320cc i think, anything bigger will be better. i.e. 550cc would do the job nicely.

You could also look at getting the injectors high flowed.

You will also need a new computer. I see you already have a aftermarket computer so you will need to retune it.

Hope this helps :P

My mate just whacked some S6 side feed injectors into his R33... with a high flowed turbo and FMIC the power FC is showing like a 65% duty cycle with these injectors on 1.5 bar of boost... They are good :P Think he paid a bit for em though, but not as much as getting like sard ones or nething like that......we looked into those as well they are exxy!

S6 RX7 ones, i know he paid like under $400 for the 6 of them cleaned and checked...I *think* from memory they are the secondary ones check with some kinda workshop about them though cause its been so long that we did them that i have forgotten the nitty gritties about it...Next time i see him i'll ask him... The thing is though the S6 arnt side feed like the standard R33 ones, they are a top mount feed, u just have to create a new fuel rail which is easy as!!! Its worth it though

Yeah he had to get his ultrasonically cleaned but it still worked out cheaper then buying some side feed injectors to bolt in.... We made up the new rail from another forum that he saw (can't member what that forum is though)....basically its just a rubber hose with metal T-piece inserted in it and then another piece of rubber run down to the injectors and all hose clamped and the standard regulator at one end as per normal...I'll see if i can get some pics of it this weekend for u!!

Cool thanks for the comments guys.

I think im going to go stage 2 and get some 550cc injectors,

Bigger fuel pump, Oil cooler, ect... Am I forgetting anything?

How much boost to run on this setup ? 18psi ? What boost is most effecient the stage 2 GCG setup ?

sound like they're aren't exactly doing a rebuild, more of a case fitting a new cartridge with the appropiate wheels, and machining that to fit ur housing, and at those price seem a bit high to me. so basically ur buying a new cartridge and machining for over 2k? not very cheap.

    • In the US almost everything is E10. It can't exceed 10% by much or fuel systems have trouble adapting. At the same time because MTBE, MMT, and TEL are all banned they need as much ethanol in it as possible to boost octane.
    • I was mostly jesting. In my experience (and probably only my experience) the R34 GTT physical airbox space is actually too small to flow the amount of power it wanted. By sealing the box, I made it so it could only be fed by the ducts themselves. So you can seal it up and get nice cold air which IS good, but at a certain crossover point: More Hot Air > Less Cold Air I don't think you're at this point. In my case merely ducting the hot air intake with a very focused set of ducts counteracts the fact it's in a V8 engine bay. More cold air obviously best. The solution looks great.
    • Nah, the OEM CAI pipe is still installed behind the bumper, it is about 5" x 3" oval at the engine side, tapering down to a 3" pipe behind the bumper where it gets all the ambient air it needs Engine side of radiator support OEM intake pipe "oval hole" that is right in front of the filter My OEM NC1 CAI pipe: From NC2 onwards, below pic, they come slightly smaller at 2.75" diameter with corrugations and a resonance chamber to reduce intake noise, lucky for me my NC1 has the bigger noisy one, LOL   Basically, the "sealed" airbox will just get ambient air from a 3" pre filter intake tube that is the same size, 3" as the rest of the intake pipe post filter, and if a 3" intake isn't big enough to flow enough air for 150 killerwasps then there are other issues The whole intake is basically the same length as OEM, but it is now about 30% bigger from the airbox back through to the new intake plenum than OEM, and the intake plenum is port matched to the head And the intake is now about 30% bigger than my 2.5" exhaust, so the suck, squeeze, bang and blow black magic should be fine, well, to my uneducated understanding of fluid dynamics anyway Talking the the guys at MX5 Mania, it may even make a few more killerwasps as the intake isn't sucking hot air, especially off idle or when in slow traffic when it would be sucking hot air  As for the difference in IAT, I haven't logged IAT yet, as I don't currently have a OBD2 reader, but I will have a play with my thermal lazer thingie next time I take the car out to sèe how hot stuff gets under the bonnet near the intake filter prior to installing the air box, my "assumption is it has to be much better after the air box is in and sealed up compared to what it is now The aftermarket "performance" CAI elephant in the room: Aftermarket CAI intakes typically have the air filter tucked up behind the bumper, with a 2.5" intake tube (the OEM intake pipe is actually about 30% bigger than the fancy pants "aftermarket" version.....WTF), and you need to remove the bumper to service the filter, which is a PITA Like dis:    
    • Nice one, I'd argue that the white S1 RS260 is certainly the best looking of the Stageas. And yes, fully agree on the forum situation. It's a bit of a shame, but at least SAU is a good place to be. I found the facebook groups to give me FOMO because people were trying to one-up each other and show off in some way. Feels much more natural here. There are people with seriously nice builds, but I can appreciate it rather than it making me question my life choices. Might be that people are more open with sharing how much work/money/suffering it takes to actually get there. 
    • Evening, wanted to pop in and finally register to say hi to everyone here on SAU!   It's been a while since I've been active on a forum, but back in the day I used to be relatively active on ClubLexus and other hobby-related forums. I'm glad to see SAU is still around, since with the advent of Facebook and Discord it seems forums aren't what they once were. As a recent new owner of an S1 260RS Stagea, I've found so many older guides and helpful tips from SAU that I figured I needed to join and say a grave thank you. My recent acquisition has only become legal in the US for the past year, and knowing that similar car enthusiasts from across the pond have already figured out the kinks and tricks to get these 25+ year old cars running well. I look forward to diving into more of the SAU forums as well as hopefully contribute some info myself for future posterity.   As a pic tax, here is one of the few good photos I have of my Stagea. I hope to get way more in the future!
