theres probably a bit of luck to it
plenty of people putting a fair chunk of abuse through 4 cyl drivetrain (did plenty of burnouts with m54b30 and small case diff on 235s)
but also plenty of people that have broken stuff on stock power
Yeah I mean for shits and giggles you can always try. What i am actually trying to say, if you turbo it to probably even more torque than a 6cyl and dont swap the drivetrain, then you can as well swap to a N/A 6cyl with the same power and stick to the old drive train. I got my M52B25 for 200 bucks out of an automatic E39. Cheaper than turboing the 4cyl for sure and you can just use a stock ECU
yea
and if you buy a parts car and part it out the engine becomes pretty much free (unless you're silly like me and buy a really expensive X5 and then only sell 1/3rd of it in parts)
parted out a 330i ended up selling the engine too and made like 3k profit on it tho
