M62 e36 swap
 

I have an m62 vanos with sport transmission that I will be dropping into my 94 325i any tips or performance options to give me a little more horse power

Hope you have some stiffer front springs and a better diff. You could always add a S/C or nitrous for 400+HP.
I'm sure you know that you need a matching DME, EWS, LCM, keys, etc unless you are using an aftermarket engine computer, right?

I dont think there is anything worth doing to a M62 for just "a little more hp." U can do cams, light weight flywheel and I think ur gonna do custom headers already so after that there is not much left... Do a search on that stuff and find out for urself... U might wanna also consider swaping an LSX, look that up too...
