Cheapest way to reach 400whp (1JZ-GTE).

Hrm... I remember reading abou that guy who, on stock twins and HKS cams got all those HP and TQ numbers. He was running 18psi though, which I hear are a bit too much for the poor stock twins? I could be wrong, but isn't the "rule" to not go over 14psi on the stock twins?

Enlighten me here bro, what is the max PSI the stock twins can take without having their lifespan greatly reduced?
Also, I looked at 935motorsport's single turbo kits, and although I couldn't tell much from the description, it does sound attractive. They have 3, one that says in the description is good for 350WHP, another one for 400 and another one for 500, and it's "bolt on", something you can do "in one afternoon".
Does this really work that way?? Allow me to copy/paste exactly what it says. This is the one for 400whp (so it says).
*** that's what I read. So, as I'm not very knowledgable about it I have to ask: if I buy this, have my mechanic install it, and that's it? As easy and simple as that? Stock ECU will be fine, and stock intercooler and stock everything else??
Run however much boost you want. When most people's turbos die, its because their turbo seals gave out on them. that will happen at stock boost or elevated boost. Many members are running over a bar of boost daily for a while now.lifesnotfair said:
CT12a's can't be run over 14psi just like the 1J has no torque...

Do you know what the Max PSI you can push on the stockers before they become inefficient.
I understand with the CT26 its 12 -14 PSI before you a genterating more heat then boost with the turbo. it's efficiency limit
whats the deal with the CT12A's And where is Fuel cut on the 1JZ?
not sure about efficiency. People with full exhaust(ypipe included) are probably hitting 16+ psi easy. If you wanted to mess around I guess you could turn it up even more.
fuel cut is at 1BAR(IIRC). I've never hit it in my car. On cool night here, it always creeps right up under 1bar but never hits it. kinda funny...

Yup and the 370rwhp was done on a stock ypipe and 262 cams iirc. I believe with 272's, an upgraded ypipe, a good tune and maybe a few more goodies it would be possible to hit 400rwhp with the stock twins. I believe Joe was the one that said that it looks like cams and a good tune are what you need to get power out of the twins. But is it worth it? The twins are my only worry with this engine as "its not if they're gonna blow, it's when".
IMO the easiest and cheapest way to get 400whp is to go with a nice single setup. Just look around at other people's setups and find what you want.
Ha ha some of the responses in this thread are just fucking funny!
Just go with a small single and some 440cc inj. and you will get 400whp or go BPU and get 300-350whp and have fun with that.

What do yuo mean man
Not that i know exactly about the 1JZ
but i have seen people pull more power out of the 7M on stock components then people with huge mods that cost a heap of allot more
if you know what you are doing. It's amazing what you can get an engine to produce and with very little extra.
Everyone mentions the "better throttle response" of the twins... well, I'd obviously expect them to load faster than a single, but still, when would the single hit full boost? .. I like the idea of the single better as it doesn't seem to involve opening up the motor, as changing the cams does.

depends on the turbo and it's setup.
when i said twin you could also go and get a aftermarket twin setup as well. To keep some amazing throtle responce while still allowing for the needed air flow on the high end.
Obviously though running twins as oposed to a single is more expensive in general.
Are you saying taking off the stock turbos and installing an entire single setup is easier than changing cams?lifesnotfair said:
This is not a good argument anyway. Cams are a good mod to do with either setup.
Anyone that thinks stock twins are better, has not DRIVEN a properly sized single setup.
It is much different then you think. Take a drive and trust me you will run, not walk, to pull those turbos off.
