I have a brief build on my profile. Just got the car its been in a friends family for years as a side project i got it fully built and running and driving. Just wondering now what are some common things i should look for. I know the cars history mostly every vacuum line and fuel line has been changed, a lot of parts too many to name. Car was takin care of but this is my first dsm. Had a few 600hp e46s and mostly faster higher hp rwd cars. Any help on what i should be looking into as far as reliability goes? Ive done some research on a t4 manifold swap and all and may be going that route soon to have more turbo options.
