PPE Engineering IS350 header development
Not very likely. You'd need to exceed 100 hp/liter to do that, and you won't get there without cams and head work too. The supercharger might get you there though...
In the meantime I have a dream, so don't ruin it for me!
If you figure out how to hack this ECM I want to be your best friend. Cause I'm gonna do a full electronics transplant into my Supra as soon as I can reflash the ECM to run a 2JZ-GTE...
LOL.. I think whoever figures it out will have A LOT of new best friends.. There has to be someone out there that can. Just need to find that genius now...
That's kinda odd given TOMs in Japan -does- change the ECU for their supercharger kit and doesn't make even half that much power.
In fact, they only make about 10 rwhp more than the stock ECU supercharger kit LMS was selling in the US.
And they only get that by advancing timing in the ECU to take advantage of 100 octane fuel.
I can't figure out what black magic people keep thinking "hacking the ECU' is gonna do to change the 12:1 compression ratio that makes large amounts of boost on the stock engine internals virtually impossible.
C'mon Kurtz, let him dream. We know it won't happen, something about physics and the universal gas law, but hey, let the man smoke his pipe and enjoy the thought.
(Of course I already took the easy way to 400+ hp by adding two cylinders...)

You think hacking the ECU is going to let you add over 130 rwhp with a supercharger to a 12:1 compression engine?

EDIT: I have been told by multiple people out here though that figuring out a way to tune our cars and hacking our ECU and fuel, we could easily gain 20hp at WOT.

You're gonna need lower compression pistons...that's the only way you're going to boost to 400+ hp. We can go through the math if you like, but fundamentally, it can't be done with a stock short block.
The math would just teach me more,but probably go right over my head lol.. I have no problem admitting I'm not that smart about this stuff.. I have just heard people talking about the possibilities with our cars, including numerous shops out here, and that is what I have heard. Ultimately only time will tell if it will ever happen.
You can supercharge our cars without lowering the compression, you just can't run a ton of boost.
You can totally jack the engine and put in thicker headgaskets. That's what hacks do.
You can run propane, methanol, and water to squeeze a little more effective octane out of the fuel. It's a bandaid, and if you run out you'd better have some interlocks in place to make sure the boost dies when the propane/methanol/water run out.
You can run about 6 psi of boost. That theoretically nets you 373 at the wheel with a perfect tune at exactly 6 psi and sea level conditions. If you go below sea level or your DA goes low, you'll have to cut boost or suffer severe detonation. Or run the bandaids with race gas and may pull another one or two psi.
Ideally you'd drop static compression to 8.5:1 or 9.0:1 and boost the snot out of it for 500 - 600 hp depending on the fuel system and tuning. Then you'd be worried about the gearbox since Aisin has never made very stout gearboxes for Toyota, but that's a separate problem.

All the dynos I've done showed 270-280 RWHP on my car with minor bolt-ons. It seems like a well designed header should put 300 RWHP in reach without any internal engine mods.
A little update for you fellas. I e-mailed PPE earlier this week and got some exciting news back 
Hi Gary,
We are currently finishing up the reproduction fixtures and then building the prototype headers. We are hoping to get them done by the end of this week. They are then going to be ceramic coated which takes 3-4 days. After that we will be off to the dyno for testing.
We have not finalized the pricing yet but will be able to after we build the prototype. Then we will know how long it takes to built a set. After that we will tool up to make a run of them at which time we will be doing an initial group buy for them.
We will update our progress on our Facebook page. And when they are ready, we will start advertising on the Lexus forums for the group buy.
Let me know if you have any other questions!
Regards,
Paul
