Hey guys , was going to turbo my n52 soon and had a few questions for it.

First of all no n54 swaps, i already have a turbo intercooler fuelpump and injectors

im turboing a n52b25 and was looking for information on any turbo builds on b25 prior

I dont want a ac delete , i think i heard i need to top mount the turbo for that.

My est power target is around 350-400 rwhp

i already have the 6mt transmission

Anything i need to lookout for while turbocharging the b25 , max boost it can take, should i add a decompression plate etc.

What turbo manifold(s) are you using? Single or twin? Cut and welded stock or custom log or tubular? Top or bottom?
