New 135i owner

Hi

I am new here. I bought a used BMW in August 2020 and thought I would have some fun with the N54 engine.

So, I got a CSF Intercooler and a Wagner downpipe fitted. With a remap and dyno I got 386BHP and 403lbs. I am very happy with this result, but was wondering how I can get more gains without spending £10000+??

Welcome to the Forum

Crazy boy !! I did read an article early this year that the tuners love the N54 engine due to it's strength and forged internals. 

The article mentioned the need for colder plugs? new coils? Twin Cone air intakes? The article was talking of 400+ WHP and with the turbo's upgraded even 500 HP at that stage I think your money would be better spent on drive train and brakes

It was a US article and their budget was $1500 

Good Luck

One of my sons has a friend with a 1 series he gave me the web address, just digging back here you go https://bmwtuning.co/build-500hp-n54-bmw-135i-335i/

I had to let him down lightly and explain he doesn't have an N54 engine.

Good Luck
