The ECU is made by DENSO, just to clarify. It may have Subaru stamped on it, but it's a DENSO unit.

Personally I think a supercharger is a much better fit for this car, if you want to keep it a smooth and responsive driver's car. While I've owned and driven a few turbocharged sports cars in the past, I can't say they were necessarily driver's cars. Maybe the RX-7 and Mazdaspeed MX-5; those are the only turbocharged driver's cars that come to mind.

/opinions.

Im well aware that engine internals and such would have to be changed i guess what im wondering is if the ppl that buy the brz are able to go to subaru for an " upgrade" an have the turbo installed tuned etc etc could we with our fr-s got to subaru and do the same thing since the engines are the same?

Yeah, small turbos are OK. My 2G Eclipse has a tiny Garrett which is good. But most cars have medium-large sized turbos which have too much lag to be fun and responsive IMO.

You can put a turbo or S/C on this car in stock form. Yes the injectors will have to get figured out. Since its a direct set up and the pressures are off the roof. But there is plenty of room on the FR-S/ BRZ to add a turbo in the same location as the wrx.

That being said. Once the ECU's are figured out, You would be able to bolt on a low boost turbocharger and run the car. 5-6 psi tops. But you will have to figure out the injector deal 1st.

Direct injection is not like the old days of the wally255 in a tank. These systems run at over 2800psi.

So clearly the answer is actually no in a literal sense.

But the HKS S/C? I suppose they haven't actually told us what's really going on, but somehow I doubt that they developed new injectors and internals to make that thing work. As arghx7 noted, Toyota's dual fan spray injectors are quite unique.

Piggy-back.

Plus the developments parts display that had the headers also had cams, pistons and rods.

Ah. Thanks, didn't realize they were all part of the kit or whatever, 290hp on stock everything would be scary shit.

Perhaps the old Frankenmotor idea needs revisiting.

New JDM Legacy FA20DIT short block with BRZ FA20 heads?

Give it cams and a turbo to support 8,000rpm, run all 8 injectors 100% of the time and see what breaks first.

how about just dropping in larger port injectors. leave the direct injectors alone.

[7thgear]

YEAH!

CUZ IT'S THAT SIMPLE.

Because it operates on DI only at full loaf.

Im sure if you are going the lenth to add a turbo you can take the time to play with the computer. Also loaf

Damn fat fingers and touch screen...

Plus your engine will be toast if you get your fueling and ignition wrong. Heh...
