Hi! I am a 19-year-old kid and I wanna turbo and manual swap my e46. I am kinda on a budget, but I want it to be pretty fast. I was just wondering if anyone has any turbo kits or recommendations for parts. Also if I could maybe get an estimate on how much it will cost to turbo my car reliably...

I was wondering people's opinions on a 325i with a 330i swap, Schrick track cams(272, 264) and a CXRacing turbo kit, with an LSD and OEM+ interior upgrades? Anything else major I should do?

Trying to turn on the MAF hack using the community patch file in tuner pro and also in rom raider and load the 512k file back in using JM and boot...

I wasn't sure whether to post on long dead forums, start a new post on Romraider's forum, or some other facebook group but e46fanatics seems pretty active. I have lots of questions concerning the MS42 maf scaling tables on Romraider and Tuner pro which on both the community patchlist .xdf and...

I got my 325ci in exchange for my Volvo V70. After I tuned my friends Nissan 200 with M50 I decided that it would be a bit more power in my car. Bought a m54b30 engine along with a 5 speed zf box. A cast manifold with T3 flange, two gst 450 fuel pumps, forged rods, dp pistons, flywheels...

My slow sled: 2000 E46 320D touring, 136 horsepower, 5 speed manual trans, 200,000 km. In the past two years the car has had lots of new parts installed but right now the issue is a lack of power. It should have 136HP but feels like 46HP. I replaced the turbo a year ago and the car has been...

Hi Everyone, I have an weird problem with my 330D. If give the car more than 50 odd % throttle below 2000 rpm you get this weird screeching or almost what sounds like to me stalling sound. If however you ease into the RPM and get above 2K its absolutely fine you have full power. I suspect that...
