bigger turbo's is by far the easiest way to do it...... say goodbye to all that low-end torque if you go for that option though.

the ideal way to mod the 335i, imo, is to max out the performance of the car on the stock turbo's. this will probably somewhere around 450whp on pump gas with agressive tune, big IC, dp/up, turboback etc.

that way you can have sufficient power to beat most cars, but still keep that low end torque that won't force you to downshift to get into the meat of hte powerband.

There are a lot of things from pistons, rings, rods, bolts, that can break and everyone would probably leave your pocket dry. We also don't know if we will need to upgrade fuel pump, injectors, fuel rail, etc. When it comes to power estimates it seems like "we just don't know what this engine can handle" is the only reasonable response.
The OP didn't ask for reliability, just for power. Read his rants. Let him blast one of his pistons off to the moon.

Ride, clever... Note that I don't have a 335 for the exact reason you speak of. I'm waiting for someone else to do the real world R&D.

Enjoy your catless downpipes...only in the state where no one cares about emissions. You'd never pass the sniffer in Georgia.

I don't have the E90 anymore, went to an E92 due to circumstances... No more catless for me unless someone can kill the rasp.

Hi Shiv thanks for the reply!

what does V2.0 alone give then?

and will exhaust help matters? what about an intercooler upgrade or are we not that far yet?

There're plenty of videos showing 360-380whp 335s with just v1.47 and keeping up with stock 997tt's

I get confused sometimes by your posts. Are you throwing up the smiley cause v1.47 cars do keep up or because people love to think they do?

Ye, it confuses me too. v1.47 doesn't make 360 - 380 whp? Where do you get that? Sarcasm?

No confusion intended. If a 380whp 335 can keep up with a 997tt, I can imagine the damage a 500whp one may inflict to the 997. That was my point.

The rolleye smiley accurately shows my skepticism towards youtube videos.

Hey Carlos!

Yes, they are twin turbos (480bhp / 457 ft lbs). Quick specs here:

http://www.ultimatecarpage.com/car/2...997-Turbo.html

V2s are making close to 400whp and v1.47s are in the 330-350whp range, not 360-380 like I previously said on my last post.

If we can get the power and the long-term reliability from the stock 996tt we can be more than happy. I personally think we will. A great deal, money-wise. And a lot of fun . BTW, Shiv should know, he has a 996tt as well, IIRC.

I still believe garette gt2860r(twin ) you can still achieved low end torque. it might start it at 2000K to 4000K

450whp with those tiny buggers? Doubt they would be able to keep that going to redline. What is 450whp going to take? Convince me NOT to wait for the Audi S4

Why should we convince you? This is a BMW forum. If you want a lead slead, by all means, purchase an Audi.

I'm sayin +1, but don't hate on audi, because my A4 that I also have is smoking any 3 series BMW except for the 335i and still at that it will be real close!! (im running KO4's)

I meant it in good fun. I am a lover of all performance cars, especially of the German variety (currently drive modified GTI). I am deciding between a few cars at the moment and the 335i/135i and S4 are on the VERY short list. Though the N54 engine is proving to be very tuneable I can't help but wonder how far you can push those little turbos safely before something goes horribly wrong. And the new A4/S4 platform is pure MINT. And with new Quattro vectoring system and 3.0L TT like the 335 it will be a monster. And, unlike BMW, VW/Audi has a very large established tuning base (no offense Shiv, I respect all you are doing for this engine). FLAME ON!

FWIW, Audi has hideous resale, even without mods. BMW has free oil changes etc., during warranty. Audi eliminated that program. My Dad had an Audi Fox in '78 and I grew up with the 5000 etc. They are a nice car, but they don't have the same package IMO.

You can buy a car based on YOUR precieved resale value if you wish (because there aren't1 million 3 series driving around ). Yes, free oil changes is a nice perk. What does the BMW 3 series have over the new Audi A4/S4 besides a less refined interior? The new A4/S4 will have optional Audi Drive Select similar to M Drive that will allow the driver to program in steering, suspension and throttle preferences among other things. Quattro has been much improved to 60/40 rear-bias and S4 will have vectoring as well. I see Audi leading the way with new technologies AND design. Perfect balance of everyday comfort and balls out performance at the push of a button. Sign me up!
