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 :yes:

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.

    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
    • I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
    • Is it alright to top up with just another green coolant?
