Hey all

Im looking for around 400kws on a rb30/25

must be, as responsive as that can get, low mounted and internally gated.

What are my options??

Cheers

GTX3582, 0.82 rear housing. The wastegate port will need to be modified.

cheers mate.

Im torn between getting my goal of having a 400kw car (my last GTR made only 393kws lol and couldnt find 400) or making a more responsive 300kwish car....

Adam,

A Borg Warner EFR8374 matches most of your requirements. Rated up to 800HP (79lbs/min compressor) and capable of well over 400kW at the rear wheels on E85. Available in 0.83 A/R T3 internal WG.

Garrett's GTX3582 is available in a T3 twin scroll but only external WG. However they do have a T3 0.82 internally gated turbine housing. It will produce less power than the EFR8374 but probably provide slightly better response.

Here's a back to back comparison between the smaller Borg Warner EFR7670 with a T3 0.83 vs. a Garrett GTX3582 T3 0.82 on a 2008 model STi running pump fuel with 50/50 water methanol injection:

Opt for the 400kW car... you know you want to

excellent worth a look!

There are other options that will meet 'most' of your requirements. But not many available with an off-the-shelf T3 internally gated exhaust housing.

Precision Turbo (Shaun is familiar with PT stuff) PT6062 CEA GEN2 (rated up to 750HP) is available with a T3 5-bolt housing which could be set-up to run internal WG. A little bit of stuffing about though.

Forced Performance have their new Xona Rotor range, which is basically their previous FP comp/turbine wheels with a new CHRA. But no off-the-shelf IWG option.

If you switch to external gate your options increase significantly.

6262, comes in a ford 1.06 in gate housing option ..which means a 6062 should fit aswell....

or people get them machined into the ford housing..so im guessing you could machine it into a .82 3582 in gate housing..?

cheers

Stock manifold will be a choking point, you need the motor to breathe.

If you want stock manifold, get a fabricator to run twin gates off it.. grouping cylinders 1~3 together and 4~6 together.. the factory manifold surprisingly is "nearly" twin scroll, bar that little notch.

OR use a Havoc Fabrication modded manifold which merges each of the pulses into 1x gate. I would expect at least a 45mm or 50mm gate off it.

GTX3582 would be perfect, especially with that 3.0L pushing it along.. heck even a GTX3576 would be perfect.
