I remember seeing a Stage 1 turbo upgrade basically a modified stock turbo for the N55 which will work on the F30 335i. What company was this again? And does anyone have this turbo installed?

im pretty sure the company is vargas performance

pure and vtt offer stage 1 turbo.

How much would a shop charge to swap out the turbo? I see they also offer an install kit for an additional cost is that necessary?

The Turbo cannot be replaced. Its part of the exhaust manifold. What they need to do is remove the manifold and turbo, open it up, swap the guts and then put the whole assembly back on.... Unless one of the companies sells the whole assembly with the guts already changed, which would make the swap a whole lot easier and cheaper.

You wrong .. it can be swap all they sell is same turbo with bigger compressor wheel .. And they swap turbo only without even removing manifold ..

The turbo and manifold is one piece. You can't change one without changing the other. Changing the wheel without removing it from the motor is stupid and is asking for trouble. Turbos have very tight tolerances and any dirt in there will kill it in a hurry.

Pure just does a core swap (with a deposit).

Swapping a turbo(s) on an N54 or N55 is a huge pain in the nuts and will def cost you $$$ to have it done right. Unless you're out of warranty or have money to burn. I would do every other mod short of tearing that thing out to make more power.

Okay, that helps me visualize. What they're doing is swapping the cold side of the turbo and leaving the hot side and manifold intact. Though you could swap out just that side without removing the "turbofold" (their word, not mine), I still wouldn't do it. Its lazy and asking for trouble. Better to remove it so you can make sure everything is perfectly clean and see what you're doing.

what are the hp gains when swapping out the bigger turbo wheel?

[Mike_L]

They're showing about 45hp and 40ft/lbs at the wheels on the dyno, but claiming "upto 70whp".

My car made 279 whp on dyno being stock + catback exhaust.
With sportcat, intake, meth kit and jb4 on stock turbos it did 339 whp.
And with the pure turbo upgrade it went up to 393 whp. So a nice increase over stock and more importantly you can rev to 6500 rpm again. With stock turbos your power drops too much after 5500 rpm.

Well I am driving this upgrade for 10k+ miles and no issue whatsoever so I guess all is good.

Would seem so. I may just be really anal. Some guys will do head and cam swaps in the car too, where I'd rather pull the motor. Anything that can be done on a bench or engine stand, I'd rather do it there. I hate working in tight quarters in weird positions.

Surprised your turbo hasn't blown up yet, how long have you had that Vargas in there?
Rather, surprised it's not leaking oil.

[F30George]

I am happy with it put down 417whp 436 torque on e35.Why would it blow up had it now for 3-4 monthes
