GT3540R and RB20/25 HKS manifold (Brand new!) 350 RWKW on low boost???


Recommended Posts

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

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!
