Except, in the Bimmer case, the 335 is twin turbo, which means more capabilities compared to the V8. Similar to people who get turbo A4's and mod them vs the n/a model.

Something else to consider is that the 2GR-FSE would require so many internal mods prep it for turbos that you would basically be without a car for quite some time. I know that most of the turbo conversions that were done (correctly) on Honda S2000s wound up being year long projects. Of course, the 2GR-FSE also has more challenges thanthe S2000, like DI and no compatable aftermarket ECU.

if i wanted 450 daily drivable hp i would just get a corvette or do a turbo upgrade on an eclipse or something. a brand new luxury car would be a terrible turbo project imo.

The one good thing about DI is your flow losses from boost pressure will be minimal. With port injection, you have to reference injector pressure to manifold pressure or you lose flow as the port pressure rises. DI doesn't have that issue, or at least, because the pressure is so high, it is not nearly as affected as a port injection setup. Of course, since the 2GR has both port and direct, the port injector maps would have to change to support any substantial boost. Returnless fuel systems for NA engines seem to have defaulted to fixed fuel pressures instead of manifold referenced pressures. I'm sure that's not good when you want to go FI, but it works fine in stock form.

Surely there is more than just one good thing about DI.

ddquach does have the lms kit, and as far as I know, his car has the most power of any IS350 in the states

the problem with messing with the IS350 is the engine management;
it really, really wants to keep you at stock power levels, and it will do anything it can to do that

so lets say you slap an intake and exhaust on it, make a pass on the dyno, and gain 25hp.

take the car out on the street drive around for a while, and come back and make another pass on the dyno, you're now losing power

if you wanted to make power with the IS350, the first step you should take is aftermarket stand alone engine management, then you can do all the normal stuff to make huge numbers like twin turbo's, super-chargers, header's, cams, etc.

sadly, this void's your warranty, and you have no chance of ever passing smog.

sorry to be such a downer, but thats the truth

if you want to learn a little more about going fast in a 350, look up Hiro Sumida (drives one in formula D) or email Steve from Luxury Motorworks (formerly LMS) which is where I get my info

good luck!

Take your 15k and spend it on a driving school.

^^best idea yet!

I know how to race... I have been racing high performance go-karts my entire life... the ones that max out at 120-140 mph...0-100 in like 6 seconds =)

Then wait for the IS-F. It's the only real solution to your problem.

You dont even need to spend that much to make the 335 kick ***. $2000?

jimmyjazz

Maybe you should go to driving school instead of pre-med then. That's how Juan Pablo Montoya was "discovered" , driving school after go-kart racing. Anyway it's a kick-a$$ good time!

phatboyc

My votes for the IS-F also.

Go for it man do your research though, fabricating and fitting manifolds and pipes shouldn't be too hard it's the Engine Management that may be an issue since this platform is still relatively new. Most people here are bench racers that quote magazine numbers and are afraid to push their cars anyway glad to see someone willing to step out of the cookie cutter.
