My car is an 89 white package, the tag inside the drivers door say manufactured in August 1988 ... So that being said I would assume it is not an 89.5

Just pop the hood and look at the motor mount on the side of the engine.

Its very easy to see if its round or square

I had a pretty serious rad hose burst so it's messy but I would say that is round ?

Square..

 

[KWITTS]

Yea square I just looked up the pics ... So I need the round ones to swap a jz then

Or buy motor mount brackets to swap a Jz onto square mounts

And the round mount subframe...

Or buy a set of JZ mounts to suit your existing subframe.

 

[KWITTS]

I need the bottom ones then

 

[KWITTS]

Drift motion sells the ones that go onto the square ones I think.....would the existing square ones be better than the round ones

The crossmember is different for the square mounts vs the round mounts. You need mounts that match the crossmember.

So you need to either get the conversion mounts from driftmotion, or fab up your own, or else you need to swap the crossmember from a 1989.5-1992 A70 chassis. I would suggest that you get the mounts that will hold the square mounts onto a JZ block. Less potential trouble than changing the crossmember, with less in shipping charges.

@Turbo Habanero: The plugs on my harness were grey, but the yellow ones from a 1987 plugged right in. I suppose that if someone who didn't know were to look at the electronics in my car, they'd assume that my 1989 had a yellow plug harness, since it fits like factory. It's only if they started to compare to other cars and wonder why this one has a voltage gauge instead of a boost gauge that they might start to figure it out.

'89 was indeed something of a weird year for the Supra. Seems like Toyota didn't want to change everything all at once.

 

[KWITTS]

And so the crossmember on the pre89 supra won't interfere with anything on the 2j ?

 

[Dan_Gyoba]

Not with the correct mounts, and pan on the 2JZ.

And the round mount subframe...

......:nono:

 

[KWITTS]

This is the sump I hear about ?
