Ha! That's not the gear's or car's fault, it's your fault for running the wrong tire. A 3500lb car should have no problem hooking 425wtq with the right tire (a drag radial if need be - the new Nittos are fine in the rain, run a snow tire if you have winters) (shoot, new 5.0 Stangs and SS Camaros make more torque, earlier, and are manageable with DRs). If you're on stock RFT's...well, a turbo upgrade is the least of your worries.

Don't you think the stock N55 exhaust manifold could be fitted with an adapter flange or cut it and weld on a flange to accept a gt40 or similar? That would still be a LOT cheaper and less tricky than fabbing an exhaust manifold from scratch.

Not likely. Possible? Sure, but getting the right cut so you have a straight section to be able to weld a flange onto, then finding the right rod to be able to weld a flange that's holding something as heavy as a turbo setup and being shaken to death all day would be challenging and unecessary, IMO. Worst case scenario, you make a cheap tubular log manfiold. Supras have used them upwards of 700whp.

Mr. Shiv!

I am looking to lease a car in the next 2 weeks. If I want mild improvements (50hp/50tq) do I need to get the 335is instead of the 335i?

I would prefer to keep it bone stuck with tune-only.

Thanks!

You rock Shiv, nice work!

+1 I'd like to know this as well Shiv (except for the cruise control part)

No problem getting those gains with just the Procede on the car. We did quite a bit better than that today on the dyno (especially in terms of torque... Ove 80lbft gains!) at 14psi peak. More results to follow soon...

nice work Shiv, N55 owners will be salivating reading this thread..

How about for us old school 6 speed manual guys? Will the software be the same/similar vs. the DCT cars? Good to see some progress being made on the N55!

Cool.

I am running 19s with Falkan452s on the street and traction is a problem.

i've been waiting to hear about this!!! so a tune only n55 may be able to keep up with a bolted n54...this sounds like fun! and porting your meth kit to the n55? i still have it sitting in my room...i assume just a different elbow?

i can't wait!!! im waiting on more info from you(dyno, 1/4time, comparison runs) before i decide to jump ship...i can see a turbo upgrade coming alot sooner for the n55.
