Just some noob questions.

[jonas427]

Hey, guys. I started looking at the 3 Series lately, because I am tired of my fwd 4 cylinder Prelude. I'm looking at purchasing a 325is. I was just wondering what kind of potential these engines have. I want to run a turbo set up and make about 300 whp, on a stock bottom end. Is that possible? Maybe later on, when I have some more money to waste ill throw in the I6 from the M3, and I was just wondering how hard that swap is. Alright, that's about it, thanks.

BMW= no turbo. They make em but i wouldnt put one on my car.

oh and the conversion is so extensive and expensive, just buy an m3

Hmmm... I am just wondering if you know how expensive BMW's are to own/mod? Since you are talking about a 325IS you are talking about making mods that will easily cost more than the current blue book value of the car, and maybe double that or more to" throw in an M3 motor" This marque unfortunatley does not readily lend itself to making engine swaps of the likes of american iron or japanese stuff. Engines and parts are off the chart expensive, and the skilled labor to do the work is also slightly to right of the cost of a highly skilled brain surgeon. Just wanted you to know what you were looking at beofre you got in.

The swap its self is not that hard but it is expensive. 300 hp from the 325 will get to be expensive in a hurry. Definately as much as the car will cost you if not more as previously mentioned. But if you have say... $20k to buy the car and can either do the work yourself or have a buddy that really knows his way around a bmw and can hook you up with discounted labor then there's no reason that you can't get it to or near 300 bhp, 300 whp would be a slightly different story and perhaps cost a little more.

Ok, so the consensus is that the 325 will handle about 7psi? You say BMW=No Turbo, well, the 325 would have to have one hell of a crappy engine if it wouldn't handle half a bar of boost. I think that would work for me, maybe not quite 300rwp but something close to it. The M3 motor is a long way into the future so don't start preaching about prices, I probably wont even end up doing it. But, I figured like "thekid" said that the swap would not be a difficult one. But as for now, I believe I will just piece together a turbo kit and put it on a 325.

www.aatuning.com check out the turbo there for 8000 but they have a supercharger for 4800 that puts it to 240 some HP and is way better than turbo, dont hurt your engine, and all that good stuff plus you can install yourself with some knowledge of cars!

8 thousand is a ridiculous amount to pay for a turbo. No one in their right mind should pay that much. BTW, a super charger is going to put wear and tear on your engine just like a turbo charger would.

hell,
check out the old write up on the m5 swap on the 325i install that those crazy europeans did... can u say "torquey" with balls to the walls.....

[jonas427]

Anyone, got anymore input?

[mmzcee]

I think its best if you stick to NA tuning...

M3 camshafts, performance ignition, chip, CAI, port & polish + bore..

I think someone got their e36 325 up to 260hp at the wheel all without using forced induction.

[jonas427]

I dont think it would be best. Trying to make good power by doing an N/A build up would get ridiculously expensive. It would be cheaper to just go with forced induction.
