996 with LS1

I didn't put a build thread here, but here is the final product. If you want to check out the build I went into further detail here: 996ls1.blogspot.com

Quick rundown:
'99 911 with an LS1 (chevy V8)
996 turbo (widebody) wheels
daily driver
built by myself over the winter

 

The only modification to the car was removing some sheet metal at the back of the engine bay. Nothing was changed in the back seat.

Basically a stock '01 LS1 with exhaust/intake, no A/C or PS; so around 350hp/350tq at crank. Weighs in around 2800lbs.

 

I had a '99 ACR a few years ago and sold it. Since then I've always regretted the sale. The 996 was on my "must own" list and the LS1 swap was also on that list so I bought the 911 for a DD. The other day when I was walking home from the office a Viper drove by and literally stopped me in my tracks. At that point I knew that it was time to get back into a Viper, but in order for that to happen the 911 must go.
I put a TON of time and money into this swap, so the sale isn't the smartest move, but the irrational part of my brain is controlling this decision. lol

I'm not sure if the weight bias changed to make the car more tail heavy. But the car dropped weight going to the LS1, I also removed a lot of things off the back of the car (air pump, heat shields, some sheet metal, Fabspeed mufflers & stock crossover, and bumperettes). The fender gap between the rear fender and tire was massive before I put coilovers on.

The torque is very nice with the LS1. I can drive around at 1000rpm. lol

 

The rear wing is manual now. I leave it up, but to lower it there are two screws that have to be removed and the accordion has to be taken out (a few clips hold it in place).

Yeah, stock gearbox. They have held up to higher power levels than what I ever anticipated.
It leaves 11's, so LSD.

There really is a lot of room with the exception of the top of the engine, intake manifold to top of engine bay is tight.

 

this.

I removed the two blocks (bumperettes) from the bumper cover, and had to drill out the metal mounts on the bumper beam. Then I used some sheets of carbon fiber to cover the holes.

here's the carbon bumperette delete plates
LS1 into 996: Annnnnnnd we're back!

Bumperettes removed from bumper beam after drilling out the pop rivets. That shaved over 10lbs off the very back of the car.

 

Thanks!

 

Yeah. I have my eyes on a Viper.

I still keep playing with the 996 though. Just installed new 8.5mm spark plug wires and set up an appointment to install LS7 manifolds, downpipes, and build a new exhaust.

 

Still looks better than the bumperettes. That area does need to be claybar'ed and it would look much better.

Some people plasti-weld plastic in the holes and then sand & paint to look like the euro bumpers. It's by far the best looking option and the most expensive/time intensive.

Others just run a euro plate behind the US plate, which covers the holes.

 

Thanks!
