Here are some pictures of the latest progress...

I got my powder coating done. In the picture of brake parts are some big brake candidates.

 

I just picked up a M122 GT500 supercharger (see pictures)$250 w/ only 1000miles and Harmonic dampener for $40 shipped. I also got a ECM to run either the 4.6L w/ the GT42 Turbocharger or the Supercharger and I plan on making a custom manifold to run an Air to Air intercooler.

PS I also changed my mind on the metalic blue to White and metalic gold stripe and rims with a metalic gold center and a polished lip. And I just got my illuminas. Here is a mocked up photoshop picture and I like it...What do you guys think?

I'm not 100% behind the gold bumper, I think you should either stick with white or chrome, but that M112 looks pretty sweet for sure! :) I'm assuming you're planning on running a cowl hood?

 

Thanks I agree on the gold bumper but I flattened the layers and now I will have to fix it...Also the supercharger is a M122 not a M112. The M112 came on the the 4.6L Cobra's and then the M122 came on the Shelby Cobra GT500 5.4L. There are M45 Mercedes 4 cyl. , Toyota Vans etc, and a M90 which came on the Thunder Bird sc 3.8L V-6, Buick 3.8L, and Pontiac's etc.

Well...here is a photo that I replaced the gold bumper with chrome.

Nice, here's a guy who's always aimin to please :) Wish I worked with people of this responsiveness level. Looks good chrome, IMHO, but not bad painted either. We've been watching you getting tons of shiny parts gathered up, have any of them gravitated towards that engine bay?

 

By the way, my M112/M122 was a typo on my part, but that's interesting, as I did't know they made both models. I was aware of the M45/62/90/112, but not the M122. That's huge.

I am working on more than the stock 4.6L that is in the car now and I would like to build/restore a 1956 Ford F100...and lots of fun with the 240z and maybe a second one.

 

PS I havn't shown all my new parts...See below 1. & 2. 255/50R16 TOYO PROXES R888 COMPETITION TIRES 3. 11" Clutch and Pressure Plate ceramic disc. 4. Boots to protect my Illumina atruts 5. 80 LB injectors for my 5.4L twin turbo, 6. Gt500 Harmonic Dampener 7. Adapter from the supercharger to the throttle body 8. MR2 rear Illuminas (already have the other (2) 9. Wilwood clutch master 10. My old sectioned setup - which is for sale I decieded to hold off on the 18" wheels with the 14" brakes for now and go with Z32 calipers and 11.75 350 track rotors and Z32 or 89' 300z rears or 86' solid rears??? 11. - 15 are some Starion Wheels and you can see the standard rotor and how much room for the 11.75" discs. 16-19 are a Cannon manifold with ITB's and a 5.4L Modular V8 tunnel ram w/ (2) Demon 625cfms. 20. Is the clutch slave unit 21. Are a pair of GT500 Mufflers that are 60mile take offs.

Well I am really close to towing the car to the welder for welding motor mounts, steering mechanism (fixing my welds) and he is going to reinforce the frame rails, strut towers, tunnel, radiator support (lowered for a bigger radiator) install the rollbar, cutout rear hatch floor and rivet or weld in plate for the fuel cell and battery, and duel exhaust...huh huh huh have to catch my breath LOL. I broke down and bought a transmount crossmember from JTR (Jags That Run) $65...I got my rims with tires mounted and well "In theory everything works" but now I am having playing with wheel spacers, adapters, hubs, and disc/caliper combos to fit these 255/50 ZR 16 888 Proxys street legal track tires in the stock but rolled fenders.

 

On another one of my motors 5.4L, (forged pistons, H beam rods, preped forged steel crank, aluminum flywheel) is done with the machine shop so that I can assemble it...Which I finnally built my own stand along kit to run up to and more than my 80lb. injectors and twin Mitsubishi TF07 turbochargers. The limit on one MAF is 750hp which is nice...But running two MAFs will yeald 1,300 hp (with hugh injectors) I would like to restore a classic heavy muscle car (pre 70s) or truck (F100 1953-1956) to put it in.

 

I am also working on building an Aluminum blocked SOHC with PI heads for sale. Also will be putting together a NorthStar V8 with ITB's More fun.

If you're doing a stand alone kit, why run a MAF? If you're doing something like a Megasquirt, they run off a board mounted MAP sensor.

 

I have a friend that was an engineer for Nissan and he worked for Nissan Racing (he is working on my twin turbo 5.4L Ford DOHC setup right now...and I will put the kits together)He also has a dyno in his garage yea...I also went to GM school (ASEP) program, and 7 years working for them and have connections with GM. I will be putting a speed denity setup for the Northstar engine.

Sounds like some pretty sound reasons :) What kind of dyno does your friend have? I was considering making a bench top inertial type for measuring small engines/motorcycles, but time hasn't allotted for that silliness yet.

 

I am not sure...It bolts to your hub. It's not the kind that has rollers.

The Dyno is a Dynatek from New Zealand and is said to be the best due to no tire slippage, strap tension and is much safer...

Well I got all the parts together (I thought) for the suspension but ran into a problem with the rear strut tubes being too big 56mm (2.21")...So I will have to use a 1970 - 1975 rear strut tube which is a 2" like the fronts and almost all coilover kits...I will be using the 280z spindles in my 240z rear strut tubes. And yes I have read a lot of threads and there is a bunch of crap and opinions out there but had to find this out for myself.

 

For everyones FYI I decided to go with Illumina's 280z front in the rear, and Mr2 rear struts in the fronts. I also have for now decided to go with the Ground Control Coilover Kit which has longer springs and I want ~200-225 lbs. in the front and ~250-300 in the rears. The weight is approximately the same a the stock 240z and I want a decent ride but perform well...I might experiment later with higher rates at the track.

Man you're costing me money. I've a SVT out of a 2001 Cobra with all the electrics and the tranny. It was SUPPOSED to go into a 54 Stude Coupe I've been working on for a few years. Now you've got me thinking about wedging it into one of my 240's. One thing on the cold air intake, have you considered a shaker hood setup? I'm a child of the 70's and they were everywhere.

Yes I did recently consider a shaker scoop (it was an aluminum one on ebay) but I like the stock hood. I am on a supercharger kick right now. I bought a 2006 Ford GT (not mustang) supercharger, 2012 Shelby GT500 M122, a Mercedes-Benz AMG 55, and a 2010 Jaguar TVS and more.

 

I can't stop myself LOL

 

"I'm a child of the 70's" also My dad was a mechanic and drag racer.

Your gonna love the throttle response of that supercharger. I have the "112" on a 6.0L LQ4 in my car. You might consider using a second stock hood to fab a cowl profile, It worked with my project allowing me to get the clearances I needed but no more than necessary.
