Yup you are correct. To fix the driveline you will need a solid axle swap with 31 spline axles and locker. Trans most likely is a new TKO600 with treated gears and a 26 spline input. Rated at 900 lbs of tq. MMR has this trans in their 8.89@alot modular mustang.

 

Cost for the trans is about 2K

Built rear end with housing is about 1500

And turbo kit at least for my car is about 6800

You forgot the cost of the fuel system, and either a SCT BA MAF that will support 700+rwhp which isnt out yet or a stand alone.

 

They must have made an adapter late, which it doesnt look like, or machine the intake somehow to fit those heads. The 01 heads have a different intake port than the 03's.

So for 45grand you can have that setup made

 

 

Other than the cam change, the engine was completely stock. They stopped testing at 20 psi, although the engine seemed capable of more. With peak horsepower at 990 hp and peak torque at 911 lb-ft., who says 4.6 engines can't make ridiculous amounts of horsepower?

 

 

RL, can a stock C/R go 20 psi

That engine isn't by any means "reliable" at the horse power level, though reliable is a rough word with ANY engine at that level, I'd want something a little more stout that a stock 03 cobra shortblock.

 

Will it do it? Obviously. Will it do it with some amount of safety? Mehhhh....

 

Then again we've tuned a few 600+rwhp KB 03 cobras running 24+psi and they seem to hold up pretty well, that's with a bunch of timing out of them, you cant imagine how ineffective those stock intercoolers get at that boost level with a Kenne bell.

Sean.. There was a TT kit on ebay for the cobras a few weeks ago.. A guy on the SVT boards named LTHL PSI has a TT kit that should almost be installed. He also has upgraded all of his internals and quite a bit of other work. There are tons of vids of his car over the net.

also take into account that the roots or twin screw blowers are stealing ALOT more power from the crankshaft than thos turbos ae stealing through backpressure.

why can U.S. V8's come with turbos from the factory?

My guess is cost of parts and cost of R&D. It's alot easier to slap a roots blower on there than it is to do all the plumbing for a turbo car.
