I too am very impressed.

Question: Will it pass SMOG in Ca?

Cheers!

This is the next hurdle. I've installed all of the smog equipment from the LS1 engine and have to take the car to the Califonia BAR referee to be inspected. There are several smog legal 944 LS1 conversions running around in California so I expect to be able to get it done.

This is really interesting. I've never seen a conversion where the car feels "right" or doesn't have several quirks and am not sure if this is just because they weren't done correctly to begin with or what. Looks good on paper though - or at least on the forum. Can't argue with the economic factor or reliability of the Chevy engine either - those things are pretty bulletproof. I have to agree a solid conversion would be worth $$$'s so will be interesting to see where this goes... I love the innovation!!!

You're spot on - the car has to feel like OEM and not have any of the quirks. The car feels solid and all of the accessories work like they should, which of course was the goal of the project. Thanks to this forum I was even able to unlock the CDR-220!

The cool thing is that I haven't driven my normal daily driver at all since I put this together :)

$5500 including car? If so, where do you find deals on wrecked 996's?

I wish :) I've got over 15k in the car. The $5,500 number is what it cost (in parts) to do the LS1 swap once I had the rest of the car together minus original engine.

Some dismantlers sell the rolling chassis - this is how I purchased mine.

Wow I was watching the build of the other guys swap for awhile and was eager to see it finished, and BAM you beat him. :)

Great job!!! Would love to see more detailed photos. Any plans on coming out with a kit (wiring, mounts, bellhousing, and detailed instructions)??? I would buy a kit and I know lot's of other guys who would. I created Silviav8forums for guys who like to put LSx engines into 240sx's so this really appeals to me.

Anyways awesome job!

Thanks! Sent you a PM regarding kits.

At least the parts will be affordable!

That's right, and the aftermarket support for these is huge.

Thanks again to all for the great feedback!

Magnificant job,save your part #s for all bits & pieces. A few sensible owners will consider this an option to paying foolish Porsche parts prices. My biggest concern is what is your actual front to rear weight breakdown now,and also can stock radiators cope?

I was curious to see if the rear suspension would squat some, but it really doesn't. The LS is about 80-100lbs heavier compared to the stock 3.4l. The cooling system actually works quite well - at idle when the phase I fans come on the coolant temps drop immediately. Will be interesting to see how it does in summer heat, but I expect it to work well.

Very cool. I know you have also seen the guy in the middle east who is doing the same in a 996 Turbo on the LS site. It's good to see your car on its wheels. More details please!

Yes, his project is what prompted me to do mine. He is getting closer to completion.

are you putting in a center radiator to improve the cooling, esp if the car is going to be tracked? my guess would be that the v8 will actually be easier to cool properly than the boxster-6. and, all purism notwithstanding, and a possible apology in advance to Loren, how about a pic of your hot '69 Camaro too? Cheers, jl

No plans for a center radiator. The LS motors are actually pretty easy to keep cool, but if I run into issues it will be something to consider. I'll post a couple pics of the camaro when I get a chance.

Unbelievable and astonishing.... Congrats.....

I've heard and seen the excellent reliable and bulletproof ability of the LSX engines. That's why I also have an 06 Z06. I baby my Porsche and beat the crap outta my vette. 20k for a 3.6(396 hp) or 10K for an LS7(505 hp). Smooth move guy. Me likey lots.

These engines are amazing. Leaks are non-existent because of the o-ring style seals and they have great longevity. So easy to make big power with them too and parts are dirt cheap.

Thank you all for the positive comments! I will take some pictures under the car and post them soon.

The engine I have is the 305 hp / 330 tq version, which is certainly respectable. Of course, I will want more and there will likely be some kind of turbo configuration in the future. I have a 1969 camaro with a twin turbo LS setup that I built that puts out around 600 hp at the wheels, so now I'm addicted to the power :)

I'm planning to start road racing the 996 and have my first event scheduled in late February. I can hardly wait to see how the car performs on the track.

As far as cost goes for the 996/LS1 swap, I have about $5,500 in it.

Thanks, I figured the response could go either way. I have seen a few threads about it and some had said it wouldn't work, so nothing like a challenge!

There is five inches of clearance between the ground and oil pan. The engine I used is from a 2000 camaro, which has a relatively low profile oil pan. Could probably do a little better with a dry sump setup, but since the pan hangs down about a quarter inch from the suspension cross member I think it will work perfectly.

Hi all, I'm new to this forum and thought I would share my project that is now pretty much completed with the exception of a few minor details. I know some purists may not like the idea of this, but it's worked out great and I put it together from scratch in less than 30 days thanks to a bulk of vacation time that I was required to take :)

Basically I purchased a '99 996 minus engine and trans from LA dismantlers with the intention of installing the LS1 in it. I purchased and g96 trans and an bellhousing adaptor and used a 50k mile LS1 motor I already had for another project. Then I fabbed up a new engine cradle, trans mount, and exhaust system for the LS1. The goal and my own requirement was to keep all existing functions and I've accomplished that by using both the porsche and LS1 computers. So the climate control, gauges, power accessories etc work like they did from the factory. It was pretty easy to utilize the existing relay functions on the car because the computers both typically use grounds to enable power to components.

The car runs great and I'm looking forward to getting more seat time in it. And now for some pictures :)

Here's what it looked like when it arrived:

After buying lots of parts here's what the car looks like now. You can see the exhaust tips I made as part of the exhaust system - pretty basic but I think they look good.

And here is the engine:
