so awhile ago i swapped a jdm h22 into my h23a 93 prelude. i retained my m2s4 trans. along the swap process of learning and building...i lost some supports/stiffeners. mainly the intake manifold to block, rear engine upper and the lower engine/trans stiffener and i think that is it. but recently (8k later) i broke 2 bolts on my rear mount ( the upper two sheared off ) they became loose and snapped. either way there gone. but my engine was moving front to back roughly 10 inches! it took me awhlie to figure it out but was too little to late, the bolt holding the whole speedo gear assembly to the trans is right beside the upper bolt on the rear engine to block mount well that part of the trans case snapped off under pressure i guess from both bolts. its kinda hard to explain but the bolt split the top part off the trans. i'd take pics but i'm far from removing the engine. anyways i want stiffer mounts all around and some things to stiffen the trans and engine together. any ideas, parts would be amazing. throw in your two cents please!

 

What the hell is the upper and lower engine/trans stiffener?

and get some 80A innovatives.

 

I use solid billet motor mounts and tranny mount, but it's not a daily driver.. Alot of people complain about vibrations being to much for a daily, but I can't tell much difference,( I use a kirkey drag seat and it's still not bad).
My mounts are one off, but as jlude said check Innovate, anything is better than stock mounts, for the most part.
