Brand new garrett GT Series turbo rated at 700 hp. This turbo is also

commonly known as the GT35/40R as it has the GT35 turbine wheel

and the larger GT40 compressor wheel.

Front A/R is 0.7

Rear A/R is 0.82

4'' inlet with massive bell mouth to suck in plenty of laminar air

2.5" outlet to suit intercooler pipe work

Turbine housing: GT30 non wastegated.

Inlet: T3

Outlet :GT30

Ball bearings allow the turbo spin forever, even when spun by hand.

Item includes Garrett warranty from date of purchase.

Unlike bushed (STD wet floating bearing) turbos that need replacing/rebuilding

at 40,000 klm in performance applications, this will only require new oil seals

at 80,000 klm. This means long term savings!

Utilizing the latest compressor and turbine wheel design these have proved to

spool up even faster providing more drivability, stronger midrange power and torque

with better reliability.

Inconel turbine shaft which is extremely light allowing quicker turbo response

and heat resilient this turbo is top shelf with no expense spared.

Recommended retail is $2960

Turbo only $1950

HKS Cast manifold.

This will not crack! In addition it can be further ported, extrude honed etc for further improvement if need be. As you can see from the pic's, the design is pretty good. All runners are split as far up to the collector as possible which will give good top end and mid range performance. It even splits the wastegate gasses.

This has a T3 flange, but is big enough to be drilled for a T4 flange if required.

I usually use these with GT30/35/40 BB turbo's due to the T3 flange. Due to the low mount design, you minimize any unwanted attention from the cops! If you need more info feel free to contact us.

Manifld only $950

Manifold and Turbo combination $2700

These manifolds are not made by HKS anymore. They now produce the Stainless ones which seem to be good! However I cant see them being tuneable in the way of further porting at a later date etc.

So basically there is only 1 available!

So that large turbo will fit in the low mount position ?

What size wastegate would i need for that turbo? HKS 60mm ?

Yes, it will fit! Nice and snug! I have fitted a couple of these to RB30/Rb25 combo's and 1 bar is reached before just 2400 RPM and 2000 with the 3040 turbo!

Wastegate size would depend on the boost you are running and if its dumping to atmosphere or plumbed back. Generally 40mm will be OK in most situations. If for some reason you want to run a measly 7-9 psi, you will need a 50-55mm gate.

Its a common misconception you need large wastegates. They are only to relieve pressure (not flow) in 99% of applications. The other 1 % is in extream circumstances. e.g Cars that have an uncanny amount of exhaust gas. I.e. RB engines wouldnt have anywhere near as much exhaust flow as a 13B even if it had an RB30 bottom end and only if it rev'd to 9,000 rpm or so.

Remember the exhaust wheel on most of these large Hp set up's flow gobs of air and only sight pressure variations are enough to control boost.

But by all means if you have the cash to flash, go big!

What's the reason for selling? How laggy would this turbo be on an RB25DET-NEO with tomei poncams...?

As laggy as a 700 Hp set up would be on an RB25 with flow to make an easy 350 rw kw...

      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.
