Need some opinions...

Hey guys so this coming summer I want to do a motor swap on my 525, the m50 just isnt enough for me. Anyway, I was wondering which would be a better use of money a s50 or s38? i realize the s38 would be more expensive (by a lot) but would it be more worth it in the long run over the s50? Thanks for the input guys.

the s38 im thinking is the e34 m5 engine and thats a very heavy engine and ive heard takes alot of maintenance

I have a 525 it is most definitely underpowered for the weight of the car.

greed but it has a lot of potential =]

You can live my Dream and throw in a....wait for it....

M70!!!


do it

yeah i heard the same on the maintenance aspect of the s38 but it would be cool since I have always wanted an M5. but how much does it weigh compared to th s50? and an m70 would epic, i never thought of that. perhaps when i have two cars i could try that, maybe a m70 powered e30

ok maybe i was backwards heres a link http://forums.bimmerforums.com/forum...d.php?t=226390

awesome, thanks for the link! as they said in there 100 pounds lighter and 100 more hp, i think i will plan on th s38... now just to figure out out the little details, good thing i have lots of time before i actually pull the trigger on this.

well he was wrong on that part the s50 in 2 pounds heavier than the s38

yeah i just looked that up and found that out myself, oh well the extra hp will still be fun

For the best power to weight ratio, go turbo or supercharger on your existing engine. You can get up to 425 HP for about the same money, maybe a bit more money but it will be well worth it.
