Will the front sub-frame out of a N/A 87 fit into a turbo 90? I know the 89+ will fit into a pre 89, but I just want to double check that the reverse is also true before I start swapping out front sub-frames.

Front Sub-Frame Swap Question

Do you mean that on my 90 with the 87 crossmember I'll have to make sure to put pre 89 motormounts on it? Or that I'll have to put 89+ motormounts in the 87 so that a motor can be dropped in easily? I don't think I'm following you completely Robert.

you have to use the motor mounts from what crossmember you have if swapping a pre 89 in you need pre 89 mounts..
You can exchange the engine mount brackets from an older block to a new design one and use it on the pre '89 subframe right???
Poodles has it correct, I'm swapping all the stuff I want from my 90 and 88 into my 87. The 90 already has a 1JZ with R154. And the 87 still has the stock sub frame. I'm want to back date my 90 because I will need to put a sub frame back into it once I remove the stock one so that it can move. I don't care about my 90 or 88, just certain parts in them. I'm not going to be putting a motor into the 90, so the motor mounting brackets are of no concern to me, just steering and rolling. So as long as I put the 87 sub frame into my 90 and have it roll and steer, I'm happy.

And I'm back dating because I like the newer designed 7M's better than the '89 and downs...
IJ. said:Square mounts are better
I'll be using the same method of motor mounting that Polobai (sp?) is using with his build, I already have the polyurethane mounts for it
.
square mounts aren't as smooth as the later style (2J's are stiffer than them as well IIRC)
or it could just be the 7M crank....
Haven't tried dropping an engine in with the later style, but the square mounts are easy to drop in...
