I can get this car for under 1000. Is this engine worth transfering in or will it weigh down the front end and screw with handling. I have been looking at engine mods and to get reliable 250ish hp seems to be lots of $$$. any thoughts?? thx

I personally think $1000 is GREAT if the engine and turbo parts are good. The engine weighs about the same as the M30 + turbo stuff, so you're really not putting any extra weight on the front.

Yeah, talk to TCD. He's parted like 30 of those things! Euro cars are an excellent money-maker for parting!

Umm... '88? In the US, the '88s were E32s and back then Europe often got new BMW models a year before we did, so it's probably an '86 or earlier, not that it matters.

A euro E23 turbo + 5 speed would be an awesome, awesome car.

I'd love such a project for a highway cruiser. Put a 2:1 or similarly stupid rear end in it, cruise at like 900 rpm :)

Keep the mechanical parts of the turbo system, but run it all on Megasquirt + Spark + Extra.

Upgrade interior bits from later 7 series cars...

It'd be a nice ride if its in good shape body wise.

The manual tranny can not handle the torque of the 745 so BMW put in an auto. Go to http://bmwturbos.scottiesharpe.com/ to learn all about the 745i and the performance possibilities.

I have to add this due to TCD comments below. It is the clutch that has trouble with the torque. There are folks on scottie's site that have the upgraded M5 3.6L clutch that is now slipping, but the engine is running higher than stock boost.

What? I think it is highly unlikely that the 745i only got an automatic because BMW feared the manual wouldn't handle the power. It seems that both the G260 and G265 will both handle huge torque and abuse.

What?!

the stock output on the 745 motor was nothing extraordinary. the 280 and 265 both ought to be able to take it, dont you think ?

I thought I'd come out of lurk-mode for this thread since I recently found a 745i that's relevant to the topic at hand.

I have no affiliation with this car whatsoever, except that I thought about buying it for a few hours. I then realized I had forgotten to take my morning dose of lithium and returned to reality.

Enjoy...

I have to disagree completely on that. My system is running more power than a stock 745i and my manual tranny is having no problems whatsoever. At 10psi my clutch and pressure plate grab STRONG -- My goal is 15psi intercooled, and my manual tranny should have absolutely no problem holding the power.
