Important 2JZ swap Questions

[zSP3CTERz]

I have searched on here and supra forums and could not find a good answer to these questions. Wondering if anyone can help?

I have a 88 non turbo. Cylinder started knocking good excuse to upgrade.

(1) I have read somewhere about people having to put a 91 or 92 crossmember in there earlier MK3's to successfully do a 1jz or 2jz swap. I was wondering if this is true or what swap this applies to.

(2) When swapping a 2JZ in a mk3 i know you have to get the JZ wiring harness, do i have to combine it with part of the 7M harness or throw out the 7M completly. Did not know if people combined them because it was helpful or because you had to.:icon_razz

(3) This would be the most helpful of all. Where exactly on the firewall do i have to hit to make this beast fit?:evil2:

If there is anything very important that i need to know dont hold back on telling me im a noob

I will have the stuff in about 3 to 4 weeks.
I Live in Chattanooga, TN if someone would like to help with this swap and charge me a decent price let me know.

1) No, you don't need to, just rear sump pan and some BIC pre 89 motor mounts. or 1jz motor mounts.
2) yes you have to combine it with the 7m...unless you want to go stand alone but don't worry about that if you are asking these questions.
3) There is countless threads on this, check the 2jzgte sticky. Also I am assuming your going 2jzgte and not NA-T

BTW, I do hope you have sourced out everything, as its more of a time/patients swap than a mechanical one(not saying you don't need to know what your doing but its not like building a 1.5jz)

Yea i know you have to in all. Its just no one has said the exact spot on the firewall that has to be hit

I'll look in my thread for the picture of where I drilled my whole for mine. I also had to use the 7m plugs for the engine bay plugs and the 1jz for the inside plugs for the ecu.

For a 1JZ/2JZ swap if you have pre 89 X member just use BIC mounts like said before it uses the stronger cheaper squar mounts.

you dont need to extend the JDM harness just route it through the speedo hole into the glove box area by going behind the radio in the dash with the harness just use a roto-zip and the metal cutting bit looks like a drill bit with the blades pealed out a little bit and route it out to the same size as the inner metal layer our fire wall haves 2 metal layers at the firewall.

Doing this mod will face the ECU connectors to the left instead of the right.

Now simpley take the 7MGE harness and cut the body connectors a foot down the harness do the same with the JZA70 body harness combine them by soldering the two together only 13+ wires depending on options. Put this jumper harness in and start car and drive!
