HIgh reving motors are fine. There are quite few running turbo 660cc motors these days (gwagen steve is in love with them, and from the limited time I have seen em work I can see why he is a fan)

So an 800cc + motor could be make to work quite well to light, huge rev range, alreay water proof electrics, carbs that will work on all sorts of angles

thats some of the main reson im considering it
plus low down balls isnt so important with a set of gears in the transfer

they put hayabusa turbo motors in those stupid smart cars,so why not keep it in the family and jam one in a sierra??

I would try to get a yammie Vmax motor v4 lots of grunt

first Yamaha V-Max came out in 1985, when Yamaha took a 1,198cc, 140bhp V4 and made a big, bad, bruiser-cruiser out of it. Now, more than twenty years on, Mr Max is back in his new avatar – the 2009 Yamaha V-Max. We’ve already shown you the first ‘leaked’ pics of this bike last week, and now we have the full spec on the new V-Max from Yamaha.

Yamaha say the primary goals for the V-Max project team were awesome acceleration and strong engine performance, precise and sharp handling, unique styling and Euro III compliance. The result is a 310-kilo motorcycle fitted with a 1,697cc V4 that makes 200 horsepower at 9,000rpm and 166.8Nm of torque at 6,500rpm.

The new V-Max is loaded with electronics. There’s Yamaha’s GENICH technology for starters. That’s Genesis in Electronic engineering aimed at New, Innovative Control technology based on Human sensibilities. Er, yeah… well. Moving on, there’s also Yamaha Chip Controlled Intake (YCC-I) and Yamaha Chip Controlled Throttle (YCC-T), which play a key role in extracting 200bhp from that 65-degree V4.

Mr Max rides on 18-inch wheels, and rear tyre size is a truly manly 200/50 R18. The chassis is an all-new ‘diamond-type’ unit made of aluminium. It’s a strong, lightweight structure that’s made of gravity-cast, CF die-cast and extruded aluminium sections. The design incorporates gravity-cast components for the main frame and pivot assembly, while the rear frame is made from a range of Yamaha’s exclusive CF die-cast parts and extruded parts which are welded together.

This combination of different types of aluminium, each with a different rigidity level, is one of the major factors in achieving the overall desired balance of rigidity. And to enhance that balance even further, the V4 engine is incorporated as a stressed member – using cast-iron mounts at the front, the centre of the V bank, and at the top and bottom of the crankcase.

I'll bite:

what, exactly, is "stupid" about a smart car?

In any case, the 660 motors NEED boost to puff up the midrange to the equivalent of a 1.3 atmo engine.

HP=torqueXrpm.

It's all very well to say you don't need torque, and that might be true, but the problem is likely to be that you'll end up with a diesel like power band - i.e it goes GREAT from 9000-12000 rpm... so now all you have is a sierra that was a a lot of work that drives like 1.3.

I drive a 660 sierra..... that drives like a 1.3 that was a lot of work. however, It was probably the easiest way to build 1.3- carby 1.6 power with EFI in a 1.0 litre.
