200cc/min 13.8ohm.

Why you need more fuel? Gonna make that duel exhaust connect up to a turbo???

As far as upgrading you need high impedance (13.8 ohm) top feed injectors.

Injectors from a 2JZ-GE will work.

Doh... Toysrme beat me to it.

Hehe...maybe...

What is the tech specs on the 2JZ-GE injector...i can't seem to find it on that link.

Do they just screw right in (direct replacemnt)?

Better yet, if you want 600hp+ RX-7 injectors are easy to find 13.8ohm 550cc injectors. MX-6/Probe GT used 330cc 13.8ohm injectors also if you're looking for a more manageable 350+ hp.

You will need fuel management and a fuelpump upgrade. Correct me if I'm wrong 88LE, but don't all the v6 VZ/MZ motors use the same pissy fuel pump as the 4c? Either way it's a shitty pump and need to be swapped for a 190lph, or a 255lph if you're really gonna build that car.

Since the 7M-GE/2JZ-GE injectors were brought up, I came across some conflicting info on another thread that nobody answered. I'm hoping maybe 88 LE or anybody could shed some light on the matter.

So what's the diff. between the brown ones vs. green?

JetspeedCamry: they're suppose to flow anywhere from 305-315cc's.

Ummm... Ok. You realize he needs to have 2.5x more power than stock to actually *need* 440cc's right?
Not that it wouldn't kick ass, and I don't doubt he can do it if he wants to, but seriously...

If you want to stick with Toyota injectors, light-green 7mge is plug & play 13.8ohm 315cc @ same fuel pressure. You will want a 190lph pump.

But the 7mgte is the 440cc....I mean if you plan to turbo it why not buy some used 440cc and tune it with the S-acf or somthing so he has a lot more play...I mean why turbo a v6 with a t25 or something like that they can easily hand a t3/t4 Can you give a brotha an Amen lol

I'm not sure.

I'd look up the part numbers for the pump and see if they cross, but my EPC don't work.

Why not get some 1000+ cc injectors then? Seeing that you seem to think that bigger is better.

Go play with this injector size calcalutor:

Why not run twin T88s?

Because 7m-gte are 2.9 ohm and not 13.8ohm and re-read what I posted above. He would have to more than double his HP to actually need 440cc injectors.

OK.... now for a reality check. If the stock engine were able to take 20psi from a t40e 50 trim turbo it would take 20psi assuming 100% perfect efficiency. Obviously it doesn't work even close to that...
You would need forged pistons and rods at a bare minimum to run that kind of power. A *very* lucky 5vz-fe crank might handle 500hp, that doesn't mean a 2vz or 3vz crank can handle that. A perfect 5vz-fe stock engine might handle 360whp. Then again there are 5vz-fe's that blow their rods still stock trim...

No offence, but I think you're in lala land if you think someone is going to get the kind of power you're talking about without a completely custom 2vz.

fyi JetspeedCamry you need to pick an aftermarket management system also. The stock ECU can only deal with 230cc injectors.(give or take)

Gees!! The info on these forums is fantastic! Thanx for all your help.
I wouldnt be going for anything BUT a custom 2VZ setup. I intend to make this a one off engine, because i've never seen or heard of anyone modding this baby. And im sure she's capable of a lot more!
Twin turbo would be great, but space is a concern with that. I have seen a 3VZ turbo setup which seemed to run only the front bank to the turbo, but i doubt that wouldve been very efficent.
In anycase, after i do my 5 speed conversion, the next mod i think ill be tackling will be a new EMS. I was thinking of a Wolf3D because there is a local place who do installs for them. After that, a rebuild and modifications will come maybe with a turbo, and i know that ill be lookn for bigger injectors, hence my question!!
Thankyou for your help guys. I really appreciate it.

Can you tell me, what is it your actually doing when you short the T and E1 terminals when checking timing and error codes??
