I have a brand new 1jz top feed rail available. PM if interested.

I will do that

^^^^ He always been pushing it on both of his gs cars. So I guess that answer my question about running e85 with a piggyback.

how's it coming along on the ecu front

Drift101

i'm still trying to get my hands on an ecu, also had an other question might have asked before but for got, so if i us the usdm ecu an get high impedence 550 injectors i won't need to add in the resistor box right the ecu won't be looking for that at all?

All the Toyota ecu's (GE and GTE) are looking for high impedance, and there are 2 setups.
1 is like a stock gte, which has low impedance injectors and therefore needs the resistor box.
2 is like a stock ge, which uses high impedance injectors and therefore no resistor box is needed.

I am running high impedance 440's with the aristo ecu, no resistor box and using the factory SC injector wiring, didn't even have to change it at all straight plug and play. The only time you have to changed the SC wiring for injectors is if you want to use low impedance with the resistor box (as in you will need to wire in the resistor box), or if your injectors happen to have different connector clips than stock which can happen with both high or low impedance (but there are plug in adapters for most types online if you want to avoid rewiring clips).

OK thanks Ali thats what i thought i can run my sc wiring with a usdm gte ecu an just run the high impedance injectors to avoid putting in a resistor box less wiring the better lol

exactly, if you do it right its not that much wiring. I only ran 2 extra wires to the ignitor, and the wires from the ignitor to the coils. everything else is a simple pin swap, or jump at the ecu connector.
Since you are using a usdm ecu, you will also be adding 3 new wires for the map sensor since you need your stock maf wires for the TT maf.
Jdm can just reuse the maf wires for the map sensor and iat as there is no maf.

Ya sounds like a good plan, I'm gonna use a 1jz head so ill use the wires for the dizy for the 2 cam position sensors

you can do that as long as you have a crank sensor on the oil pump, otherwise you will need to swap to the newer style oil pump, but be sure to always use a ge oil pump on the ge block. gte pumps give too much pressure for a ge block, and a head swap doesn't change that.

That's my plan thanks for all the help

Great thread about the OBD2 GTE ECU Conversion!

Drift101

hopefully in the next few weeks i'll be picking up my ecu, getting a set of 1jz twins and looking for a head then its rebuilding time for the block an wiring up everything

you have your work cut out, I got tired just thinking about how much you have to do.. lol.
sounds like a good plan though.
