Thumbs up Building an LS1 Powered Widebody Porsche 911

So for anyone interested Here is my build im starting.

Youtube Series is here Subscribe!!!


I will be needing a lot of help from the members here as a lot of things on this car will probably have only been done one or twice from info I can find,

Now before I Start let me start off by saying the car was purchased with no interior, motor or box. The plan was to be a budget build and building what I wanted not what you think it should be. My previous car was a Mercedes E55 the last of the Supercharged V8s. I have always loved the sound and feel of a V8 and on the same note I have always loved the timeless look of the 911 so I shopped around looking for a project as I never had plans of a doing a resto.

Behold my 76 911 that came with a 993 widebody. So I jumped in the car and drove to sydney and pick up my ride.

So the plan is to give it a GT2/RSR look but run a turbo LS1. The transaxle is a custom built one for me from a company in Sydney.

This will be purely home built and on a budget. You are all welcome to offer ideas and help on anything you think me assist. I'm open to keeping this group build I'm just not interested in any of your purist opinions. I was thinking of making Youtube vlogs nothing high quality but more of update evey few days rather than one a week or month. Whats everyones thoughts.

So lets get started.

So I have started on fitting my GT2 flares and working on making my roll cage. I picked up a cage from an alfa 105 which is almost the same size. with a few easy mods it should fit quite easily as the main hoop is the same size.

So first job is to remove the remaining interior and clear away some of the dynamat for the mounting plates for the roll cage. I tell ya this **** was a pain to remove Super sticky and sharp like a torn coke can. But im glad the car had it as the LS1 will be loud!!

This was the cage I picked up

Next I spent a few hours playing with my flares i was keen to see how the fit was with my wheels as I was worried about the offset. So it was time to get cutting.

I know what it feels like to be Nakai now and cut up a 911 lol

Now the fan part. I was not going to waste money with a ****ty 915 so instead went with a custom box for a lot les money and the internals are all brand new. The box is a STI 5 speed with the rear drive unit removed and shortened I went with a the oversize ring and pinion and and double syncros on 1,2,3. Single syncros for the rest. it comes in shorter than a 901 box and will allow my to have the engine a little higher and forward more.

Now the above pics show the fin in a 912 the 911 has a slighty bigger tunnel so the fit should be very easy. Ill mount my shifter higher and and cut down the throw.

I just picked up my gated shifter for that ***** sound lol

Cool project...although 5 speed Subaru arent the strongest of boxes. Even in a Subaru 350hp or so is pushing things unless you take it easy on them

It was that or the shitty 915 with no syncro reverse and 250hp max rating and 5-7k rebuilds each time it breaks
Also most common suby issues are blown bearings my unit runs double bearings and because it 2wd there is no viscous coupler the other part that usually breaks. oh well we will see how it goes

HP determines how fast the gears break, torque determines how many break at a time and how far the pieces go. Worst case a STI rally sequential box could be in your future.. Just sell a kidney..

Cant wait to see how it all comes together.

I love that there is finally an older body Porsche build. I love these compared to later bodies.

But these bring a pretty penny compared to later cars, so makes sense why so many guys end up with those
