I bought an 86 MK3 7m-gte to use as a track car, i've been drivng it round for about a year and now the time has come to put the bitch up on blocks and start fucking with her.

First up i've removed my v1 7mgte motor, still on standard sizes on everything. Only fault i've found is the center main bearing has chenobyled.
Plans for the motor are cp pistons and probably machined and balanced rods and balanced and nitrided crank.

i'm also pricing up stroking the motor, but we will see what happens.

yeah 86.5
Hmmm not looking good so far, the crank is bent and the block has corrosion damage around the coolant holes that is too close to the bores.
I don't think i'll find another block anytime soon i might try metal spraying or bronze welding the areas.
Do any of you guys know how much material can come off the block before things get fugly?

So i've bought a 2jz-gte vvti i'm looking to sort out everything i'll need for the conversion before my motor gets here from japan. I plan on making custom mounts and getting a drive shaft made to suit where ever i end up placing the motor.
My main concern is utilizing the factory 86.5 digital dash. I plan on using a standalone engine management system probably microtech.

My engine is due to arrive soonish and before i begin converting and rebuilding it i wanted to test run it without the ecu. does anyone know if this is possible?

No.
You need something to control injectors, spark...everything.
Certainly you can crank it to check compression, though.

No. 2jz is sequential fuel and ignition. 7m is batch on both. You would have to wire it for batch just to test it.

Ok i used my 7m ecu injectors and ignition system and it worked fine my next step is to mount the engine and wire it all up properly

plans for suspension? motor swap was a good start, 2jz will take a lot more abuse at the track. 7m's aren't bad rebuilt but it's nice to have a motor you can redline a lot safer and longer.

I'm just going to keep my d2 coilovers and most other things stock. its come to a part in the build where i could either do a ground up rebuild or just slap my engine in and run as is.
The motor doesn't sit back as far as i wanted before it hits the firewall. And the specs for the japanese nostalic race series i want to enter are apparently under revision so i might just pause my build for awhile incase i modify something im not allowed
