The 24v swap is not for everyone but it can be a good option. Depending on what you want to do w/ your car a turbo m42 may be a better option. I would steer clear from a m20 or m30 at all costs though.

Hey I loved my M20 and M30, they were easy to get, easy to work on, cheap parts, good power(with boost ofcourse) and they were reliable. The one dowside to them was the timing belt. My first m20 one chewed up third on my getrag 265 (boy was I pissed). My m30 though never got completed:( . That one was destined for a higher order. I was prepping it for 30lbs and 9k rev.

they are okish but they are a VERY old design and not efficient at all compared to the newer motors.

Granted I'll give you that. They are good bargain blasters though.

Those numbers do not jive with the other places I have seen. Granted with this being the internet, who knows.

However, you are forgetting an important issue. Weight is one thing, where the weight sits is another. Not only are you adding more weight over the front snout of the engine, but you are pushing the accessories forward as well. The front of our motor is over the crossmember, as you move forward of that, the weight is more and more noticeable. 1 pounds from the front bumper is probably worth 2 in regards to chassis balance since anything in front of the front axle, LIFTS the rear.

To be honest my car handles very very simmilar to how it did before the swap. I am using Korman's Clubsport suspension for an e30 m3. But a large factor is that I have done a lot of weight reduction to the front of the car. I weighed my car before and after the swap and its actually lighter now. Thats obv not due to the motor but to what I have removed from the car. My car is very neutral but I can bring the back end out whenever I want due to the increase in TQ, and keep it in when I want.

The 24v swap is not for everyone but it can be a good option. Depending on what you want to do w/ your car a turbo m42 may be a better option. I would steer clear from a m20 or m30 at all costs though.

I am considering picking up a 318ti really soon. It will be the DD but it might eventually get turbo'ed.

I guess it all comes down to what your plans are for the car and how good you are working on cars or writing checks.

Everyone I have talked to with a 318 and 325 says is very noticeable. Not bad driving, but not tossable like the 318 is. The fact that you lightened your car that much is probably why yours drives well.

How noticeable, well some have said they wished they had kept the 318, and one of the mechanics from Metric Mechanic was planning a nice 3.2 stroker, but after driving Febi's car, those plans have now changed.

With aftermarket suspension and lots of weight reduction I have no doubt that your car drives just as well, but toss in the lighter engine again, and how much better would it drive than it already does. How much do you have invested in weight reduction, swap and suspension? A bit more than just an engine swap I would imagine.
