Light powerful little engines ...

Help me think ... what light-weight little 4-cylinders can be built to put out 200+ hp with decent torque numbers and can be adapted to an SM465?

Ecotec comes to mind but I think there is some issue with starter placement vs the manual trannies??? Can someone confirm?

VW?

With a little bit of work, you can get a 3RZ toy motor to give you 200HP

A 200+hp VW motor is going to cost $25,000+

Screw VW then. Didn't know they were that pricey ... hell you see them so often in the sand rails you'd figure they were a dime a dozen! That many people are dropping that much coin on sandrail engines though? Crazy ...

Just curious, ever think about the 3400 V6 engine? 325 lbs and some basic upgrades and you can push 240hp 280ft/lbs like the one Jesse used in his comp buggy.

/forum/general-4x4-discussion/576381-my-2007-badlands-comp-buggy.html

Just throwing that out there, not sure if you were looking for something lighter.

Edit: Would that would mate up to the SM465??

Lightweight V6's would be an option too. A 4.3 Chevy is too heavy though. Something in the range of Ecotec - 22R weight is what I'm interested in.

I thought about those but I can't seem to find any info on putting the manual tranny behind them. I know you can put an auto but I think there is some sort of problem with the starter placement vs. the manuals. I would appreciate if anyone can confirm this?

Hell an LS motor is around 400 and some change, hard to beat that power-to-weight and how much lighter can a 4 cyl really be?

I don't have many specifics for you but My wife used to have a Honda S2000 and it had a 2.0liter four 4-cylinder that stock made 200HP. It was already mated to a six speed manual and was RWD. I have seen these cars dyno at 300 plus RWHP so it would do what you want for sure.

Only bad thing about those engines is the power band. 4K and below it was a normal 4-cylinder. 4K and above it made all of it's power

Hard to beat a new Ecotec with direct injection and forced induction. Also a rear trans is available stock from the Saturn Sky and Pontiac version. Going off memory, I think those were around 275 hp.

Toyota 22R probably weighs about the same as a 4.3. The newer Tacoma 4 cylinder motor is a far better choice then a 22R. It may not have the 200 HP (probably close though) but they have a bunch of low end torque and still rev pretty well. Plus all of the great Toyota drivetrain.

Still the Ecotec will weigh less. Other options are the 2 to 2.4 liter turbo motors from Nissan, Toyota, Mitsubishi, Chrysler etc. All will easily make 300 HP with out much work.

the sky and solstice are a RWD application so you could just divorce mount a t-case behind that?

do you want a bellhousing pattern? I can get that for you if you want....

Not so much a bellhousing pattern as confirmation that the starter has no issues with the SM465 bellhousing ...

2.3 ford. not sure about the adapter, but if you want power and light weight they are a good way to go.

Shortstar. IIRC, 225-250hp and not terribly heavy.
