If you ask me, it looks like they oversized the hood for the needs. The engine bay looks crowded, but a low profile screw blower will take up no more room that the intake that is there now. We shall see.

Turbo lag is non-existant on small displacement, high duty cycle engines or where you group cylinders together to maximize pulse timing. The higher the CFM of the turbo the more it will lag obviously. So larger power always takes spool time. The turbos BMW uses are the size of a canned ham.

And even though the 335 has small turbos, there is absolutely no room to add a larger trim turbocharger. That is why you don't see any turbo upgrades to that vehicle, only tuning!

I've said it before, the R&D upside is not enough for companies to build a supercharger or turbo for the IS-F because of its limited production and even smaller demand for owners who actually want to void their warranty (TRD exception) and make prodigious amounts of horsepower!

Intake/exhaust is all you will see down the road...and you can forget about tuning because from what I have researched, Toyota keeps their ecu's on lockdown; And I doubt yamaha/skunk built this car to be modified.

Good Point! Very accurate..I guess Swift racing technology is out..Due to voiding warranty..FU**:mad: :mad: This is one draw back on limited production cars..Oh well! I guess one can hope TRD does something, if not I'll deal with it..No Biggie!
