The 2010 Chevrolet Camaro comes with a 304 HP (6,400 rpms) and 273 ft-lbs (5,200 rpms) aluminum, 60 degree V6 that delivers 17/29 mpg on a 3,800 lb car. The motor uses 87 octane fuel and probably weighs about the same as a stock 951 motor.

A stock turbo S has 247 hp (5,800 rpms) and 258 ft-lb (3,500 rpms) and weighs in 3,300 lbs.

The Chevy V6 would have a hp/weight ratio of 10.9 compared to 13.4 for a stock turbo S. The torque curve in the V6 is also much better than stock 951 motor.

Any thoughts about how effective this motor would be in a 951?

Would a 60 degree V6 fit under the hood? Chevy 90 degree V8s barely fit from a height perspective. The V6 would be shorter and not as long but wider.

I'd rather rock the LS3 that comes with the new SS model. However I think its very outside of the box to drop in a v6. I don't know of anyone thats ever done it. It would have alot of cool factor just cause it would be so different.

This V6 is considered to be one of the 10 best engines every built according to the articles I have been reading. The direct injection, computer technology and variable cam technology make it incredibly efficient.

I have thought about the V8 but my concern is that the car would be too unbalanced. My 951 has 320 RWHP, escort suspension, ect and I actually do worse on DE days than in my stock 924S. The 924S is wonderfully balanced and forgiving. I have applied to much gas to the 951 on several occasions and gone off the track. (Yes, I am getting old and my eyesight and reflexes are poor.)

My theory is that the V6 in a stock Turbo S would provide a similar experience to my 924S. It would be an effecient, reliable, balanced and well manored car. The Porsche engineers did a wonderful job when they designed the 944 to provide a very well balanced car. I would to stay in this sweet spot.

If you can't do the time, don't do the crime.... I guess what I'm saying is, do the crime, let us know what the time is like!

Swagger93

Ugh, I know this is beat to death, but ruin an n/a, not a 951.

DVC

Absolutely not. Go to Squire's Autowerke in Bellevue and check out Squire's 944 LS1. Don't waste your time on the V6.

LSx or bust

I think I read that 10 best engines article a while ago. It seemed pretty biased towards domestic and mass market engines.

Sure it would probably drive great, but I don't think its enough of an improvement to justify the swap. And yes, hood clearance is a pain in the *** with engine swaps in these cars. ...I still have a 2jz-gte sitting in my garage because without dry sump that thing will never fit under the hood. If you're going to do the work to develop your own swap, pick an engine you REALLY like. My pick would be that Audi 4.2 but it's really too big for the engine bay.

I have seen a pic of a 911 motor under one of our hoods. Now that was weird. Just do the V8. They weigh about the same as our motor too. There's way more info on them and you can see that there are plenty of good success stories from this conversion.

There ya go, John. I fixed it for ya.

If ya want a Camaro, buy one.

Hmmm.... 3.8 turbo buick might make it interesting...

seattle951

I have no interest in Camaros. They are ugly, heavy and roof is too low for someone of my size to drive.

For many people on this forum the ultiimate goal is horsepower. If I shared this goal, the V8 would make sense. I am more interested in drivability, safety, and reliablity. Lower emissions is also a plus.

The V6 is attractive since it will provide more low end torque than an S2 and more hp than a turbo S while at the same time providing outstanding reliability, low cost repairs, high gas miledge, and very low emissions. Since the TQ/HP increases are modest, the platform should be able to handle the upgrade without other substantial modfications.

At this point, my hobby budget is depleted. However, I will consider this down the road if the motor will fit. With a 3,200 lb Turbo S this upgrade should provide interesting results.

"I am more interested in drivability, safety, and reliablity. Lower emissions is also a plus."

Then buy a Honda, rather than screwing up a Porsche.

The LS1 transplant is a good solution from most perspectives;
- it fits beautifully. There's far more space in the bay with the LS1 than with the original
- conversion kits are available, so there is no rocket science required
- the cars I know that have had the transplant are dead nuts reliable
- its a dream to drive. Still well balanced, you just need to roll onto the throttle rather than mashing it :-)
