Turbo M30 versus M5 engine swap

[Jay 535i]

Just a hypothetical question, for the moment...

This would give me roughly the same result as spending the same money on a turbo kit. Which is the better route?

I guess with 98k miles, this engine is due for a ($$$) rebuild?

"950.00 CORE CHARGE APPLIES, FULLY REFUNDABLE UPON RECEVING YOUR CORE"

Unless you've got another M5 engine to send back to them, add $950 to the price

Personally I would go for the M5 engine. Everything in the M5 engine is built to work together. Turbo charging an engine not built for it IMHO would put loads on certain areas that may not be able to cope. You'd end up spending a fortune on uprated parts and/or balancing to make it cope. Don't forget to put some money aside for brake and driveline upgrading.

Dude ever heared of the Alpina turbo I'm not sure but I heared something about seq. dual turbo, the Alpina used the m30 and boosted it up the .
Go for the turbo, but don't forget the 5 speed to handle the at least 400hp the boosted m30 will dish out.

At least not only. I think I've seen some dumping out over 1000hp.

You have a perfectly good car now, why bother? IF you really want a M5, why not sell your car and get one. You get everything you want in one package,designed by BMW, and you won't waste any money. By the time you're finish "upgrading" your car, it won't be worth squat. In contrast, a real M5 will always be that and worth more than any wannabe fixer upper. I say, stay the course, or go all the way and get the real deal!

That's what I did, Jr too. No regrets except maybe the extra fuel burned. Of course, all memories of the cost vanish when the tach needle passes 5K...
