2jzgte loom quick question

[Barrington]

Will a 2jzgte wiring loom from an aristo plug straight into a 1jzgte non vvti and ecu?

[jzk25]

No. You could connect it to the engine(you wouldn't) but the ecu is completely different.

[Barrington]

So are you saying that I will need to change the plugs that connect to the ecu?

[midnight_purple_GA70]

not really... you could but it would be much better to keep aristo loom with aristo ecu

you should be able to sell the 1jz ecu for the price of a 2jz aristo ecu

unless of course you have a 1j and a 2jz aristo loom then ide be getting a loom/ecu for the engine you have...

[Barrington]

Are there any downsides of running a 2jzgte ecu with a 1jzgte?

[midnight_purple_GA70]

i would assume that the fuel mixtures would be too lean due to a 2jz being factory programmed for 440cc injectors and a 1j having 380cc injectors

maybe not "too" lean but other then that im not sure of any other major flaws...

that being said why not buy 1j loom and ecu for 1j and sell 2j loom and ecu as it will be worth more money?

[Barrington]

I just thought it would be top hard to use a 1jzgte loom in a car that came factory with a 2jzgte

[midnight_purple_GA70]

so what has actually happened?

was the car originally a factory 2jzgte auto aristo and the motor has blown up so the replacement motor is now a 1jzgte?

give some background on the conversion and it will help decide the best point of travel

[Barrington]

It's just all ideas at the moment but I have an na 2j auto shift kitted aristo, and it's starting to stack on the k's so na-t ain't a good idea, but I've got a 1jzgte with loom and ecu with low k's and I thought about doin a swap and then manual convo soon ish after when I get the funds for it.

[midnight_purple_GA70]

personally if it were me and i could get away with doing it ie i didnt need the aristo as a daily or anything

ide pull the engine and box out of it and sell as a package or sell separate

then buy the manual gearbox setup

and drop the 1j with manual in

would be the easiest i would think...

you wont be able to get the na ecu to control the 1j
it may be another option to manualise the auto and drop the 1j motor in with ecu and loom...

[Golberg]

Excuse my ignorance, but if you have an 2JZGE Aristo and you want to put in a 1JZGTE where did the 2JZGTE ECU and loom come from?

If you have to buy them anyway, why would you run anything other than the 1JZGTE loom and computer?

[Barrington]

If I did do this, the aristo wouldn't be my daily anymore. I'd be loosing all seats and putting bucket seats in the front, and alot of unnecessary shit would be going too, to bring the weight down. The idea is that it wouldnt be driven on the road much at all, and more the track. I wouldn't bother putting another cent into the auto as it's not gonna suit what I want the car to do so the auto will be going. Yea I know the ge ecu won't work but I had the idea that 2jzgte loom would be easiest to put in the aristo because it is factory in most aristos. Then from there I'd try and hook up the 1j or 2j gte ecu to that until I had the funds for a standalone

[Barrington]

And I just assumed that I would have alot of messing around trying to put a 1jz loom into an aristo compared to a 2jz loom as it isn't factory

[midnight_purple_GA70]

well i will have (a mate of mine is parting out his car) a microtech lt16 with 3bar map sensor and hand controller with a loom to suit a 1jz for $1250

it would be more messing around trying to match the 2j loom to the 1j ecu than it would be using a 1j loom and ecu

keep the engine loom and ecu the same and then its a matter of joining some wires at the fuse box and some on the body loom to ecu connector

Is this a big job? And tell me, am I an idiot for considering putting a 1j in an aristo? Ive mentioned it to a few people and they think its an absolute waste of time. I want alot more power, but I just dont have the sort of money to buy a 2jzgte, and ive already got a 1j sitting around.
I know this has been done before but its not very common at all.
