M coupe/Z3 engine weights vs. M3 engine weight?

[jeph23]

Once again, J!m is awesome. How much roughly do you think the 5-liter swap would run? I might be interested. I was thinking about doing a SR-20DET conversion, which will be quite the task, but, I would consider the 5-liter swap for sure. I want to do something totally different, hence the reason for the SR-20. Granted, I am not a fan of Jap motors, but this is quite the tank of a 4 banger, especially with a T3/T4 hybrid turbo. But I thought it would be cool to have a completely modified TI like this, BUT, if I could keep it all BMW, that would be the way for me to go. Rough scale, what do you think a 5-liter swap would run me? I am so seriously interested J!m.

Lets see the m54, mtec. I want to know what you had to go through to get one, how it went in, your opinion of it, everything.

how much weaker would you say that 2.8 liter aluminum block would be if a person was contemplating throwing a turbo into the car too..? What kinda weight difference is there between the aluminum and iron 2.8 blocks?

do not use a aluminium block that has been overheated. even slightly!!! the threads will pull out of the block. i have replaced several of these heads and had this problem repeatedly

I intend to do the swap in the next few weeks, and it is very likely I might just post a write-up on it all. It seems that the most difficult hurdle will prove to be installing the gas pedal potentiometer (since it is drive-by-wire), but we will cross that bridge when i get to it!
