Im front mounting the turbo. The rad will be in the trunk. 2x3 frame will stop at crossmember mounts, the be a removable tube clip. Ill be running a remote mount electric water pump. http://i1278.photobucket.com/albums/...psaf51a7cc.jpg

Man, great build! From the license plate it looks like you'll be putting it on the street as well as the strip?

The goal is all around outstanding car. Street, strip and road course. 700 rwhp is easily obtainable.

Cool build. Pretty tough to do a build that's good in all 3. I figured with the tubbed rear you'd go with an autotrans.

It would be faster with the turbo but I like to drive my car. Not stab and steer. 335/35/17 is whats going in the rear. Plenty of tire choices in that size. I just try to keep all the factors that make great cars in each kind of racing and try to pick the best compromises between them all. Weight, power, traction, chassis stiffness and suspension. I hope I succeed!

Im using hooker swap manifolds and flipping them up and forward. Most people use truck manifolds. The hooker manifolds have larger primaries and are tighter to the engine.

This is the turbo size.borg warner s475 turbo - Google Search

Sold the big t6 turbo and bought two smaller s366 t4 turbos. Borg warner Pn 177275

Hey great to see you back! I have looked at this thread many times and been amazed. You are a fine craftsman for sure and I hope you keep the photos coming!

Its been slow going with it lately. Time to work on it and money. The frame is next to start on.

I've been busy. http://i1278.photobucket.com/albums/...ps013aeb00.jpg

Gonna do some more tomorrow. Finish mounting front sub frame. Triangulate the front rail to the upright. I set the turbos on the rails just for the pure excitement of it. This thing is gonna be wicked! http://i1278.photobucket.com/albums/...ps18fe7c0d.jpg

I couldn't finish getting front 06 sub frame mounted. I need another stick of 2x3.

and to think I thought my holes in the floor pan were big

Keep the updates coming!

Yeah your hole is no comparison. Lol

I've been a little busy working on it.

love your build, going to do some of the same things on mine this fall. awesome rear end, looks like it can take a beating. wish I knew what width and the mfg of that rear end, I want one.

The housing is a competion engineering fab 9 inch. The rear tires are 335/35/17 on replica 10.5 wide cobra wheels. The housing has to be built to your specs.

Damn man! Do you still have the car? I have a shop called the Rat Factory in Indy. I've built some wild stuff, but Your Miata project is nastier than mine! Tens my ass! I'm thinking low nines?
Mine's a back halved, 8.8 rear, 350+.060, 12.2:1, nitrous car. I'm new here, but seeing your build's making me reconsider the front clip.

Yes I'm still building. To much going on right now to get anything done on it.

Well life has gotten in the way for the last couple months. I am working on getting the coilovers squared away now. I'm dealing with Brian from Hanchey vehicle technologys. Hopefully gonna order special made front and rear coilovers that will fit my build.

The radiator in the rear sounds like a great idea...get the heat out of the engine compartment and free up some precious real estate under the hood. You may want to check NHRA rules if you want to run it at the dragstrip. Section 1:1 states "All cooling systems/radiators must be installed in the stock location for body style used."

They have a lot of rules and it would be worth your time to look at them if you want to run at a dragstrip. Here's a link NHRARacer.com - NHRA RULES

My BossFrog double hoop rollbar won't pass their rules but I'm hoping they don't enforce the rules on "test and tune" nights.

Thank you for pointing that out. Well doesn't that suck! Maybe a fake one up there. Lol I wonder why that is even a rule?

The custom coilovers were going to be pretty penny. Trying to spread the money in the right places made me go with the Ohlin's kit. It allowed me to purchase the 14 inch willwood front brake kit. The upper mounts for all of the shock mounts have to be fabbed regardless. I figured might as well do it with factory mounts. Easier to get replacement parts later.

I'd like to hear more about the rear radiator you are doing. Got any updated pixs?

You need to pray you don't hit anything. a good straight 1/4 impact and that frame rail is headed straight for your groin.

recommended change would be to put a bend in it. that way if you crash the frame will be pushed upwards.

I'm no where near the point of building the radiator system. I will be running an electric remote water pump.

I get what your saying about the frame. I'm gonna triangulate the bottom of the vertical 2x3 where your feet will go. The dash bar of the cage will get tied into that vertical piece as well. The front sub-frame connects to both of the horizontal and vertical pieces. I could take a chunk out of the bottom of the front rails before the sub-frame starts to make a make shift crumple zone. Thanks for the input.
