advise on upgrading my motor

i have a 85 325e and was wondering if i were to bore out my stock motor, rebuild it, do cams, pully, intake header to a full exhaust, would that also better a better option? and then maybe a turbo or SC?

I'm in similar position.

'87 325is 265k miles tired motor not worth rebuilding though.

Going to order a brand new factory fresh BMW 2.5 I motor Monday for $3750

2 year 20K mi waranty.

Two other options Ive considered was a super eta motor which is suposed to be hot, but hard to find/build.

Ive head people sugested replacing eta motor with i motor. Not the super eta but I'm not totally sure of the diferences. bore stroke, displacement.
There a good post on that topic here somewhere. I think in FAQ's section.

Also a newer model used M3 motor and conversion kit which may be cheaper, but I hate using conversion kits and someone elses used motor.
But ive heard like $2500 on ebay.

Anyway I have till MOnday to change my mind.

I'd definetly like to hear more feedback on this topic as well.

I'd like to know if theres a good SC for this motor. I hear more about good turbo system than blowers.

Cheers,

SC? BAHN BRENNER! Great performance gains... Expensive though!
Have fun with it!

An ETA with a 88 and later i head would create a near ideal compression ratio for turbocharged fun...

If you want N/A induction an 88 and newer i head have much larger valves, with the addition of the 88 and up pistons with your 2.7's stroke. Top it off with a chipped DME, with headers and larger injectors and it's burn out time!
