Hks Gt3037 Pro S Results ?

[Devils_Advocate21]

Not sure on that one but everwhere i took it they hadn't seen the pro S housing flange here, so had to get it made up, not sure on purchasing a dump, you could always try out the hks site give them an email and see how you go

What about the dump pipe gasket?

would that be able to be fabricated?

and would I need to change water and oil lines if I had a HKS2535 previously installed?

If you have a genuine dump pipe with the machined surface you don't need a gasket.

I installed a 2835proS kit (they come with no gasket) on a mates 25 and there were no leaks at the join.

The braided lines on the 2835 were the same as the 2530 that was installed prior so theres a good chance your existing lines will be fine.

I don't have a genuine dump pipe, will be making a custom Stainless one, would I still need a gasket?

It wouldn't hurt

[Downforce]

So you had to get the flange made up? It's not readily available?

HKS exhaust housings are a different 'custom' shape for the internal gated turbos.... you need to get a flange laser cut, or buy the HKS dump pipe with the turbo kit.

I learnt a few things from this thread so thought Id give back some results

GT3037ProS Specifications

Power Output: 480PS

COMPRESSOR:

-Wheel: 56 Trim - 57.0 Inducer / 76.2 Major

- Inlet Housing: 100

- Outlet Housing: 50

- A/R: 0.60

TURBINE:

- Wheel: 84 Trim - 60.0 Major / 55.0 Exducer

- Inlet Housing: T3

- External Housing: External GT-Pro outlet; 0.87 A/R

Wastegate: Internal 1.2kg/cm2

Yes it fits without spacer plate

You do have to play arround with the turbine and compressor cover to make it fit

and a slight modification to the actuator mounts

My previous 2535 oil/water lines fitted up with no problems

I guess garrett cores use same fittings

I had a custom flange made up and a custom split dump pipe,

Was told that you do not need a gasket, its a metal on metal connection

this is probably the hardest and most expensive part

Mainly due to the odd shape of the flange and the orientation of the turbo

The intake is 100mm so I had to find a 100-75mm silicone reducer which was a challenge in itself

the result on RB30 is below 435rwHp@21Psi

Awesome work Luke. About time too. lol

What other mods? Still on the stock exh housing? Plenum? Any idea on the rpm relevance to the graph?

Yeh, still stock exhaust manifold and plenum

other mods explain on this thread

I'll try to see if I can get RPM graph as well as boost
