Well, after months of research and reading through posts on this and other forums my project has officially begun. I would like to thank all of you for posting information about your projects progress. This makes life a lot easier for the rest of us in understanding what we are getting into.

The plan:
Install a stroked LS3 (416 CID 605hp/560ft. lb. torque) and a T56 transmission on my S30. Install Bad Dog frame rails; have a custom aluminum tank built that will allow dual exhaust. Fit a built R200 LSD with 300zx turbo axles and billet stub axles and adaptors. Send the body to a restoration shop for complete disassembly, paint and body work to be completed. Replace all weather stripping and send dash to be refurbished. I’m sure other things as well, I will update as I go.

I plan on not cutting any corners on this build regardless of what it will cost, my estimate so far is between 45 and 50K, who knows I may be off there too. This is the second car I purchased and I have owned it for 23 years. The car means to me more than it will ever be worth therefore I don’t care how much I spend on it. This project should take a couple of years since the body shop is telling me 6 to 8 months from the time they get the car. :(

Here are some pictures of what I’m staring with. The car looks OK in the pictures but it is a long way from being done right.

Nice, good luck with your project. Looks like you are setting the car up for drag racing.

Update

I removed the fuel tank and the 4.10 R200 (pictures attached) which I will be sending to John at Betamotorsport. He was kind enough to find me a 3.36 R200 to swap with. He will be installing the OGS Super Lock LSD on the 3.36 unit for me, powder coating the case and installing a chrome plated finned differential cover. I will post pictures of the unit once I receive it from John.
I just received a set of 89 300ZX turbo axles yesterday. I will take them appart this weekend and send them to be powder coated to match the differential.
One of these days when I hear back from Ross at modern motorsports I will be able to order the billet stub axles and adaptors. :(

I will be very interested to watch your progress. It looks like you will have some of the same dilemmas I am facing. The first confirmed one is mating the Z31 CV shafts to the stub axles. I hope you are successful in cornering Ross as I too NEED that solution.

You may want to up your total project budget by a few bills. My LS1/T56 ground up resto-mod project is projected to come in just shy of $40k with the drivetrain being free (purchased complete F-body and sold parts to cover its cost) and 95% of the work being done by yours truly (and 1 tuff z).

Keep the updates coming!

Thanks for the compliment, all my Corvette friends think I'm crazy for what I'm doing. They say the car is nice as it is and to leave it alone. I'm doing it because the car has a certain meaning to me and I want to build a one of a kind Z out of it. I could not do that to another Z it just would not be the same.

Alainburon:

When finished the 240Z will have a greater horsepower to weight ratio than a new Corvette. I also want a 240Z that is unique. Using a Gen I and started at a baseline of 500+ Hp/Tq and exceeded the baseline in valve lift (honest .600+), duration, solid vs hydraulic roller and fuel injection with 1000+ cfm throttle body.

Hey Alainburon, just wanted to thank you again for the awesome deal on your old engine. Your Z is sweet the best I've ever seen. Truly unique. My old man still can't believe your throwing an ls3 in it.
Women and Zs are somewhat alike. Both will take your money and drive you crazy. The only difference is after a while women lose their sex appeal.

Update:
The S30 engine and transmission are both out and sold. I received the Chromed R200 cover along with a new OEM diff. mount. Axles and drive shaft have been taken apart and dropped off at the powder coaters. Still waiting for a opening at the fab shop that's going to install the frame rails and build the new fuel tank. Still waiting for Modern Motorsport to answer my email from a month ago. Anyone know how to get a hold of Ross?

I just removed the wheels to send back to Centerline to be repolished. Waiting for my rear tires, I bought 4 just in case they stop making them. Had to order them from England since that size (285/40/15) is no longer available in the US but it is still being offered in Europe. Yokahama is making these tires in very small numbers for the European market only.

Got my hood and pre-fitted it. Needs some work to get it right plus I need to open the front scoop. Hopefully that will force some heat out of the engine bay.

Sorry to hijack the thread but how in the world did you spend 40k?! If you dont want to post it send me a pm. I'm really curious as I'm building an LS1/T56 240z with all the works and I'm not calculating the final cost even near that number unless you're replacing EVERYTHING with new or NOS parts and doing a COMPLETE rotisserie build even then idk because you said you are doing the work yourself. Just curious

I know Craig and I am sure his numbers are correct. His car will be a lot nicer than mine and I know I have near $30k in mine. O you just wait until you have to keep by parts and while I am at it starts.....hijack over :P

Not spent but expected (projected) to spend. Clive is correct, I am being very meticulous about tracking and estimating this project. $24k so far and the car is still just a shell (actually I have a lot of the goodies to bolt on.) So how does it become nearly $40k. Purchasing a good Arizona car then starting with a complete ground up including soda blasting to bare metal, many coats of paint, lots of sound deadening and heat insulation, lots of carbon fiber bits, all AZC underpinnings, Brembo brakes from an EVO, Z31 R200, all new bolts & seals, long tube headers, LS1 modifications, Vintage Air system, roll cage, Corbeau bits, etc, etc, etc.... Suffice it to say I was shocked when I plugged everything into the spreadsheet. I would be more than happy to pass along the spreadsheet if it helps you.

If I wasn't constantly working on this car I would actually start a build thread. Sorry for having not done that yet.

Hey, before you go nuts with a custom aluminum tank you should know that there's a readily available universal tank from Tanks Inc. that allows for the placement of dual exhaust. I had this system custom made with mandrel bends and Magnaflows and it fits fine around the tank. No doubt a much smaller investment than a custom aluminum job.

Yea I'll shot you a pm with my email. I'm just curious because I got AZC brakes and TTT Q45 rear swap and planning for 3k dollar wheels and I'm no where near that :mellow: I guess if you do a full rotisserie build it can come up to that much. I was tempted to do that but Clive and others talked me out if it. Car is going to get driven so not worth it to me and the rust on my car isn't bad. Create a build thread!! I'm sure we'll be meeting once our cars are done! Sorry...hijack over

Thanks,
That looks good, unfortuantely I had to put a deposit to get an apointment with the fab shop that is doing my aluminum fuel tank and welding the frame rails in place. The tank is supposed to use the stock 280Z fuel sending unit since I want to maintain all my original gauges. I guess I'm too far into it to back out now. :( Great set up on your car, thanks for sharing your picture.
