[AWMSPORT]

Heywhats up fellas, I picked up my 335i about 3 weeks ago:rocks:, and as a Fanatic I defintly cant complain! But had a question. Since turbo talk is new to me, what is the psi our turbos have? can we make them higher/lower? what is a good number?? again this might be a repost but i have no clue what to look for/or in this case probally have no clue wht i am talking about. if somone can hellp me i would appreciate it.

Thanxs

8.5 psi max stock. Compare to other turbocharger cars it is a low reading number but it does not mean nothing, the engine is aid by other technologies that compensate for the low boost:

4 valve per cylinder
high compression ratio(fast revin)
bi-vanos
FMIC
Aluminium block

generally speaking, the engine is very well optimize performance wise.

As well as the capability to overboost 0.2 bar for elevation changes.

^^I did not know that but thanks for sharing. Does it have a eletronic boost solenoid controlled by the ECU?

We are not talking about the "overtaking" overboost right?

I believe the ECU compensates for the elevation change, raising boost from 0.6 bar to as high as 0.8 bar to maintain the same power output. I am sure someone can chime in exactly how it gets accomplished.

"So what's under the 335i's hood? "We have two Mitsubishi turbos running at 0.6bar (8.8psi). These can boost to 0.8bar to compensate for altitude using the two electronically-controlled wastegates," Udo explained."

I believe Shiv mentioned having an overtaking boost option with the PROcede, like the Sports Chrono package with the 997TT.

hm mitsubishi turbos.

I wonder how the car would do with twin 16G units (stock size off Lancer EVO).

I am starting to believe this car has a VERY strong potential to start putting numbers down that would put it into Supra range....well at least the lower output ones.

Turbo upgrade with less restrictive exhaust/DP + appropriate ECU tuning could yield some pretty nice gains over the current set up. I am sure we will see that upgrade eventually.

I would be concerned about overheating (see some of the active threads), especially in an auto.

...and less restrictive (bigger) turbos & downpipes help in managing the temps...

[335boosted2Dmax]

Alot of the heating issues are coming from automatics that were built in the period where they werent adding in the oil cooler and thats why many of those specific cars are over heating..........

I doubt these motors can do wat a supra motor can on stock internals. The internals in those things are freakishly strong. But hey, who knows.

You'd never fit the 16G-L twinscroll with it's 10.5 hotside in there though At ~38-40lbs compressor wheel it's too big for a twin and too small for a single.

No it won't...n54 block is aluminum while 2j is cast iron. There is no other i6 that can touch the strength of 2jzgte motor.

Also, from what I have gathered, the space is extrimely limited to fit larger turbos in a 335. Some have tried already and commented on how hard that would be. I am still waiting to see somebody to come out with a nice, free-flowing downpipe for our cars.
