where does the cx racing mounts place the motor? how low and how far back? how low is to low?

I hope to have the answer to that question soon. I've been waiting on the 1JZ to 350z transmission adapter I ordered so I can place the engine in the car with the trans.

I don't have measurements but the cx racing doesn't set the motor as low or far back because it is using the stock mount locations. The lowest and furthest you could have brought was from beta motorsport. But cx racing isn't far off it wouldn't take much to push back and lower if you needed too.

I used cxracing. I just cut the own mount plates off the subframe, relocated them back where I wanted engine. Very simple.

He is very right on the bolts. I currently have what I had in my garage thrown in. I need to run to ace hardware.

 

As far as mounting to frame rail. I seen that go bad. Very bad.

^^smart way to mount the engine to the rails. don't weld in place till you find out if the shifter will  locate in the factory hole .slide them along till it fits.

 Jaguar V12 mounts are much stronger/better insulation than the range Rover, only a couple of MM thicker, 20mm bigger diameter, and only about $15 more expensive.

As long as you have a "finger" clearance, you wont have contact problems.

Yes 1 finger or more depending on size

The gap is already ok for gearbox remove without complete engine remove...

not a big fan with Solid mount...

to much vibration for me...

I have some solid bushing but wants more confortable option

Solid mounts on an inline 4, definitely. I've found that a smooth running JZ engine, even with solid mounts vibrates the car less than a urethane mounted inline 4.

^^^ smooth running could be the key.

Solid, as in, aluminium -or solid, as in, not silicone filled?

I've used the  solid (rubber) v12 Jaguar mounts on;

a 260Z with 1J turbo,

928 porsche with 3uz V8

300zx TT- factory engine, (but modified the mounts due to ridiculous cost of factory mounts filled with silicone gloop)

two TR8s (3.5 litre and 4.6)

Never experienced anything even resembling a slight ( out of place) vibration

my actual 2JZ mount project.

The idea is to have already part of the mount on the frame and on the subframe.

I use 4mm MDF to create prototype

The engine mount rubber is from a Range Rover
