I got a setup where you can use a stock auto bellhousing to adopt a th400 to a 1uz.

2JZ-GTE's only have jets for piston cooling.

There is 8 cylinders to bear the cylinder pressure. In case of the 2jz, once the motor is prepped for big boost and enough power is made to break things you will see cylinder liners crack between 3 and 4. With good 1/2" head studs the head won't lift at 60psi. Top fuel dragsters run aluminum...

Hoot Hoot! for water injection!

The turbonetics drag celica did use vvt cylinder heads as per TRD.

Another thing to consider is the shape of the piston and the head. By using vvt head on a non vvt piston you have a great chance of rendering the quench area useless. Making the motor less efficient and less tolerent to detonation. Also toyota has been moving the ring lands closer to the...

FAST eDIST Turboandrew, The FAST eDIST2 or even the old eDIST will work with stock toyota camshaft pickup sensors. You can use the other unused camshaft sensor to reference the edist box.

Shim under bucket conversion on early vv-t heads was mainly for lighter valvetrain according to Toyota. The later vv-t heads use buckets with built in shims. There was no incident to my knowledge that a shim in a bucket ever ejected.

The V angle (head angle) did not change, the intake port angle was altered to have a straighter path to the combustion chamber. All VV-T heads use the same diameter valves.

The squish pad shape and angle were mainly changed to improve engine combusion efficiency.

3120....Sounds like it's going to be stripper!

Those kind of angles are ok if you plan on going drysump.

I think you are overdoing the lines. Your proposed setup will flow to 1500 horsepower. For you i would do 2 6an feeds into each rail. Both rails should outlet into the fuel pressure regulator and will flow enough fuel for over 1000 horsepower.

More if you pick up a Stage 2 A340e from Supercar Tuning Center. I hear they use a bigger 2nd gear sprag to replace the stock unit which happens to be it's weakest link.

Cryo treatment affects the entire metal structure. Sometimes it's used in combination with heat treatment. Check out http://www.metal-wear.com/index.htm I had them do my stock pistons and connecting rods. They are located in Antioch, IL. They have a pretty good turn around time too...

Lexus wants $1800 for a SC400 harness.

HKS does not use SS Autochrome! There is a definte difference in quality. SS Autochrome parts are mig welded first and then they tig over it for looks. The real difference is on the inside.

got any pics of the blown motor?

The A340E does not make a good tranny for a drag car unless you're making no more than 500hp. EMS EMS can control the stock trans. There are also standalone trans computers that will do the job.

I was under the assumption that nitriding only makes the surface harder while heat/cold treatment affects the entire metal structure. Cryo treating the heads may be a better idea if you are looking to spend some more money on your motor.
