A friend of mine had this link up on Facebook, and it leaves me confused. I mean, I like it, but at the same time....you put WHAT in a Porsche!?!

Up for sale is my 1999 Porsche 911 Carrera (C2) with an LS1 engine
128xxx miles
6 speed manual transmission

The reason I swapped the LS1 into my 911 is for reliability over the issue-plagued M96 engine. The LS1 weighs less than the M96, makes about 100ft-lb of torque and about 50 horsepower more than the M96 in stock form.

Currently, the 911 makes about the same horsepower as a new 911 and more torque than a new GT3. The 911 also weighs in near 2800lbs, so the power-to-weight ratio is far better than stock.

I built this car with the intent to have a reliable daily driver 911 and I have driven over 3000 miles since the swap was completed It is one of the most fun cars I have ever driven, every time I get in the car I have a smile on my face.

The alignment was set up with no power steering in mind, so the steering is direct and comfortable. I average about 20mpg city/highway and 22-25mpg highway.

My friends who have driven the 911 love it. The 911 draws a lot of attention and many people comment on how it doesn't sound like a Porsche. Everyone seems to love the car. Whenever the engine cover is popped, there is a crowd.

In its current state, the 911 is plenty powerful. However, swapping to a bigger camshaft and aftermarket valve train for a few hundred dollars will put this car in the power levels of modified 911 turbos and well beyond the power levels of GT3's. So it can be left as-is, or modified to be a monster for very little money and effort.

Exterior:
The car is in good condition for its age. But it is not perfect; it has rock chips on the front, scratch on the front bumper, minor scratches on the right rear fender, small dent on the trunk, and needs to be detailed. Overall, I estimate it's 8/10 for a car of this age. A professional detailer could easily clean up the exterior to look almost new. But this is a driver's car, one that you can daily drive or take to the track and not worry about a scuff

Interior:
The interior looks like it has nowhere near 128k miles or 14 years old. The leather on the seats and steering wheel is in good condition. Carpet is in very good condition. All switchgear is in very good condition. All plastics are in very good condition. Dashboard is in very good condition.

The bad:
1. Exhaust gasket leak at the manifold on the right bank. Simple and cheap repair.
2. Center console hinge broken
3. Remote key fobs don't work

Can't fault it too much, unlike the picture I saw of a Beetle swapped with a GM iron straight six.

I don't fault it at all, it's just kinda like the E36 BMW that I've seen with a 327 under the hood. It's cool as hell but it makes you cock an eyebrow when you open the engine compartment and see something that doesn't quite belong. The result is badass though.

No power steering? I'm kind of not down with that. Granted weight is where you want it for parking lots, but my experience with hooning a non PS equipped car dictates that when the tail starts to let go, you're not going to catch it.

Now that was only one car, and it was highly, laggingly turbocharged, so there's that factor too, but i dunno. No PS seems like a bad idea to me.

No PS on rear-engined car like a 911 is no big deal.

Now if you excuse me, I must go build up my biceps. LOL

The no A/C is a bigger deal for me since I live in Texas, but yeah I can definitely see that making for the car being a pain in daily driving situations. I wonder how much it would cost to re add PS and A/C to the car.

Rad car, I featured it back in Sept on my little blog here , but I came to the same conclusion as most folks. Awesome, strange and it will find a buyer when the price drops a smidge.

yeah PS and AC deletes always seem a bit half assed to me. I know it makes sense from a price perspective, but a car doesn't seem finished without those kinds of accessories.

WRONG, WRONG, WRONG.

I badly want a car like this, (a narrow-body 996 C4 AWD, in my case)

And this one has been ruined.

Put an SBC in a Corvair, if you want a rear-engined SBC-powered car, and absolutely must replace a boxer engine with a V8.

I would argue less with an SBC swap in a DeLorean, to replace the under powered PRV-V6, if you want a rear-engined SBC-powered car.

You don't see people gutting anemic old 70's and 80's Corvettes to put in a more powerful, and better balanced, and shorter length, later model water-cooled porsche flat 6 under the hood. Not even an SVX EG33 engine.

the few available modern boxer-powered cars, should stay boxer-powered.

Something positive, though... the 996 Turbo wheels look fantastic on a narrow-body car, especially a clean-looking black one.

Motor swaps on 996 911's normally are done after the IMS failure has destroyed the engine. This one was done before from what I could tell.

Note, swaps like these are not uncommon on 928's as well, as many horrible things can happen with that engine (but that's normally v8 to v8 swaps).
