I didn't mean to make it sound like I was calling you out, I just didn't want the OP to think that 270whp or more was fairly 'easy' to achieve. ~240-250 is realistic and relatively easy, beyond that it gets more complicated and less simple bolt on  |
I have all that. 3SI, Headers, MILVS, and a tune.
Bought the 3SI used and replaced the DISA valves. Installed all the parts myself. I did the milvs when I replaced my VCG. I would say the car has probably 260 whp as most dynos show 250 without Milvs.
Lack of TQ was the biggest issue and the diff swap helped that.
The rear diff was the easiest swap. Used out of a wrecked car with 21K miles for about $300.
The 3:73 makes more of a difference than all the other bolt-ons combined.
I have less than $2K in everything. Did the work myself, and I've never worked on a BMW before.
Sport seats + M-Sport suspension that came with the car plus the above mods and lightweight wheels....and the car is extremely fun to drive.
