My M47, model year 2005, e46

[LunaCraze]

I am considering upgrading my 95k-mile, mostly stock M47 with a hybrid turbo, downpipe, fmic, etc. in order to obtain 230 hp at the wheels.

I was wondering if anyone has any advice on getting the most out of the M47's power upgrade? How was it? How bad was it? What was the mistake? Which further modifications are required?
Is there anything you would have like to have known before you did it yourself?


Because it's a significant amount of money, particularly for a student, I would really appreciate any type of response that would help me comprehend it and decide whether to commit.

Are you going to watch this to see whether they make 230? I'm not sure, but I will.

Buying that automobile would be the worst financial mistake you could make. Do
Get something reasonable to spend your money on; you'll be doing yourself a service.


I won't be nasty, impolite, or pissy if I say this, but it's astonishing that you're investing in a 21-year-old automobile that may explode under increased acceleration (because you have no idea what the inside is like) instead of using that money toward your education.

Swapping out the engine with the 30lt is less expensive and simpler.

If I hadn't gone on a whole Scrooge rant, that is what I would have proposed.

Thereafter, he can attach a larger turbo.

Screw that, I'll build a bespoke manifold, attach two T66s, and mount the intercooler on the top of the car.
