Turbo or not?

Have any of you seen the white coupe w/ a turbocharged M30ish engine that is for sale on Ebay now? I wonder how he built his.

Cheers

The m106 is quite different from m102
Different compression, boost, operating system.
Early Alpina and BMW turbo systems offered low compression and high boost.
The 4hp22 eh version uses an extra large bell housing for the big P1 torque converter- I would wonder whether it would fit in the coupe.
Keep in mind the m106 developed max torque at only 2200 rpm and managed 144 mph in
3 gear. In 4th gear at 80 mph the engine was only running at 2000 rpm so it was hard to wear out.

I was thinking of the m106 in the e24 with the 4hp22.

Was there more wear because of the bigger forces involved?

Does it feel more nimble or just more beastly on the highway?

More beastly is a good term!
The 745i and euro cars including the M
Versions used the great big diff.

Saw my old post had started up again & just to bring it up to date-

I dropped the project due to some serious health issues and it doesn't look like I will be taking it up again.

May be putting my coupe up for sale in the near future, as i am not driving it much.

Will be going the Ebay route but will post it on the board prior.

Hi: I was looking for info on Turbo set up in my 1972 3.0 CSI. I think it has all the early 7451 turbo components with the Djet fuel injection. Id the FI in your picture Djet? I have 3.5 Engine but I have not figured out what head I have yet!
Thanks
Jahan

I am re-reading the Rotrex info- that has to be one of the least informative web sites around.

Good news is that Active Autowerkes is a dealer & they are in my back yard.

Will give them a call tomorrow.

Their description of the product sounds a lot like the Turbo Encabulator. If you haven't seen it, check it out here:

But the bottom line is that you simply can't pull enough power from your electrical system to be able to stuff enough air into the intake to make a difference. The only energy source that is powerful enough is the engine via a belt or the exhaust gas via a turbine. Don't waste your money on an electric supercharger no matter what BS they put in their ad copy.

Never say never Ian. You should watch this:

Ok, so they have super capacitors in the trunk that store up power to run the electric supercharger for 2-3 seconds until the turbocharger comes up to speed. You wouldn't be able to run the car full time with the supercharger running off the car's electrics. Innovative, in that the tiny engine gives you good milage, but only good performance with some tech tricks.
