N43 Rotrex supercharging project 320i

[rick881]

hello there, i'm new to this forum.
I'm from Italy, driving an e90 320i Lci year 2011 with 50k km with N43B20 engine

After reading a lot i'm gonna start my new project with this car. I'll try to supercharge it. I've found 2 kits on the market, one is from Arma Speed, but no answer from it after few email.

The second from CAP racing, from China, based on a Rotrex C30-84.
I know that a kit will cost around 6-7000$ but my idea is do it by myself buying aftermarket pieces.

Anyone try to do it? anyone knows specifically what the arma kit is composed?
I've found from a local dealer a Rotrex C30-84 with some pulleys, intercooler and pipes for about 1500$. The biggest problem is how "make" the mounting bracket, i wrote many mail to chinese companies but no answer, hope they'll write me soon.

Boost will set at 0.5 bar
K&N filter
Homemade exhaust from a workshop specialized in race exhaust

And NO, i will not sell my car and buy a 335i, even if i wish, because i've bought it 1 year ago, and buying a car like a 335i in italy means more than 2000$ taxes/insurance every year

If i can do spending around 1500-2000$ i will try to do it on my car

thanks for every advice

Most guys in here are states side and the n43 didn’t come to the states. That’s a nice idea cause with the direct injection on the n43 you should be able to supply enuff fuel. The bracket as you said is the trickiest part. Custom build it and start selling brackets. Both n46 n n43 guys always want more power but keep hearing just sell it n buy a 335i
Good luck !!

thanks mate.
yesterday i was looking price for some 335i here...about 13-14000 euro with 110-120km year 08-09...it's not a bad price, if i can sell my 320 for about 12k euro, the difference is the price for a turbo kit...but the problem is with 290cv i'll pay 1300euro taxes for year against 350 with my 320i.
Do you know if there's a version with less kw to pay less taxes? i'm thinking about 330i and tune it with a jb4 if it's possible cause the 328i doesn't exist in europe
