Hey Big Dave,
My S10 has the 5-speed manual transmission.
The diesel I plan on putting in it is a Mercedes 616. Yeah, I know...it doesn't have a ton of horsepower - but I am more looking for fuel economy and renewable fuel use.
It's also a 2.4l displacement, just a tad more than my 2.2l 4-cylinder gasser. The engine is almost exactly the same size.
Netgain (
NetGain Motors, Inc. Home ) has some nice big motors that you can buy with a yoke on them to hook right up to a driveshaft. Unfortunately, they are not cheap, and you still need a controller, batteries, etc. which all add up in cost.
The "hybridization" that they offer is basically adding a motor right into the middle of the driveshaft. It's a neat idea, but I am not sure exactly how somebody would do a home version of it.
