328 engine change

[dudehog]

am i able to put a 325i e36 engine in my 328i e36 without any changes? will it drop straight in? thanks people.

the 325 engine (M50) is smaller than the 328 engine (M52) so i'm not sure if it will bolt straight in...

why would you want to do that? it's not a huge power difference between the two, but still the extra torque from the 2.8L would be nice...

the transmissions seems to be a little different, realoem.com says that the 325i has the SD5-G and the other has the SD5-Z...

take that for what it's worth, just trying to help.

thanks. yeah i do like to have that extra bit of torque. i'll stick with the 2.8 lump. is an engine change a long process?

Between any of the 6 cylinder engines that came in a e36, relatively speaking, no. Going from a 4 cyl to 6 cylinder is a little more complicated, but really, it's still fairly straight forward.

That said, keep the 2.8. What you can do though is get a intake manifold from a 2.5 and bolt that on -- should be good for at least 15 horsepower, even without an engine remap.

yeah, man. engine swap are long...even if you are a mechanic...

at the very least it's going to take a full day...

i wouldn't do it...

+1 with the M50 Intake Manifold Swap on the 2.8.....
