Just saw this over on Renns, read the whole thread. Being a 911 fan and Camaro fan, this is the "cats meow". Fantastic job.
Any auto-x or "spirited" runs yet? how stout does she feel?
Anyways, great job, interesting read, well done. Thank you for your service to our country as well, as a civilian my whole life, i still salute y'all.
cheers, mike

This was one of the most enjoyable threads to read I've come across in a long time! Nice work Mr. Fierofly!
The most brilliant part of the build: the access panel that allows you to reach the back of the engine from inside the car. Why doesn't Porsche install those on all their 911's?

You have no idea how nice a hatch like that would be with the stock motor, it's a damn ship in a bottle to work on! Half the work starts with "lower engine 3 inches" with the unsaid prepare to be sliced and diced. A sizable amount of things simply require engine removal (sigh)...

Yep the turbos are pretty much bullet proof but i was talking about the m96 in these cars. Infact its because the ims sucks that we get to do the things we do to them.
And the cost to get. 996 turbo to 750 hp would cost more than i have in my whole car.

Yeah the NA motors were pretty awful IMO. The turbo cars take less than you think though, good turbos, intercooler, fuel system, correct tune. Price of entry however is a good bit steeper. Oh, clutch is required. Silly Rabbit sells pretty much everything reasonably priced. A V8 costs way less than the engine build required to go any higher though for sure! I think a V8 swap is a wonderful way to go with the NA cars. The IMS crap killed a ton of these and the motor build prices are insanity! Porsche has had a few issues that should've resulted in recalls that they've gotten away with

Well it seems a lot of my pictures that I posted during this build thread have been held hostage by photoBucket. They now want $39 a month to use their 3rd party hosting. NOT ME. So if you view my Profile photo albums you can find some. If you need specific ones, send me a message and I'll add them also. Sorry for the trouble this might cause.

Hopefully they will come to their senses and make it reasonably priced or someone like google, amazon or yahoo will rescue them from their horrible decision. I have been posting builds for over 10 years on various sites and all my images are dead now. Dick move by Photobucket..

Fierofly, does your ABS work? Mine has never worked and the ABS & PSM lights are on...I get why the PSM light is on, but haven't looked into why ABS would be as well. (I believe the vehicle speed comes from the ABS wheel speed sensors, so I know at least that portion is working).
Thanks!
Thanks!

Yep, my ABS light is on, but I'm not sure when or if it has always been on. hasn't been on my priority list to troubleshot it. Car runs and drives great. I've got around15k miles on it so far. My main annoying issues are the random reset of the Porsche ECU to get the water temp gage to work and I have to blip the throttle prior to coming to a complete stop with the AC on.

My Coolant gauge does the same thing. I got a simple digital gauge that displays any OBDII readings, which I plugged into the LS3...that's how I monitor my coolant temps.

Thanks for the reply. Do you know if your ABS actually works? (My light is on, and my ABS does not work). I read on a Porsche forum where someone took a 996 ABS system to install into a 914 (?), they had to find a pre-CAN 996, which only has a 2 row ABS connector (whereas our CAN ABS has 3 rows). I assume the combined ABS/PSM just gives up with no 996 engine signal.

I found the power wire for the Porsche ECU and installed a toggle switch under the dash, it gets used maybe once a week on average.
Also, starter will not work if this switch is off, cheap anti theft, just don't bump while cleaning and wonder why car won't start LOL

I see that there has not been any recent activity on this thread but just wanted to add my two cents worth. Excellent job and post!!! Now for a stupid question. I didn't see any lifts in any of your pictures. What kind or combination of lifts did you use? I'm starting one of these swaps and I'm going to purchase a lift but want to get the most affordable and easiest to use for this application. I have a standard 8' ceiling height. Also, how is the car doing?
