Here's a dumb update, since it has been like 4 months.

I bought a 1992 Miata roller. Did some measuring. And now I'm going to attempt an IRS swap from the Miata onto the Cosmo.

Pray for me.

WAHT! Sounds insane, do it and I'll watch.

It all seems like it might work. Same width between the rails for the front subframe, rack, suspension arms, sway bar is all contained as a unit. Only serious modification would be to lower the shock towers. For the rear, there is tons of room back there. The fuel tank is in the trunk, and there is nothing else back there. The rear is also a self contained unit. Nothing except the strut tops is 'outside' the assembly.

Go for it. Sounds like a definite improvement to the solid axle and you won't have to worry about breaking it with a rotary.

djmtsu · 08-13-2015, 04:36 PM

Improvement all around! No more solid axle. Vastly superior suspension. Brake parts the are stupid easy to source and upgrade. Bolt pattern unleashes an infinite wheel choice. No need for a 2 piece driveshaft. Rack and Pinion steering. Do I need to go on??

This is awesome man, cant wait to see progress! Hell, I can't wait to see it on the road!!

Fuel tank is cleaned up, should be good now. All that is really left is to find the new battery cables I bought (or just get more), get a battery and fire it up.

Had to get a new heater hose (the elbow off the rear iron) since the one that was on it disintegrated as soon as coolant flowed into it. Looks like there is an oil leak in the oil cooler area. Don't know if it is just a connection issue (I have new crush washers) or if the cooler is cracked. If it is, I'll steal the one off white Cosmo for now.

Once it is fired up and running, I will need to figure out if it is the brake switch or wiring keeping the brake lights from functioning. Then, figure out the washer pump, and horn. All these are simple and can be rewire in short time, so I'm not concerned. I do need to find a gauge solution for coolant and oil pressure. Not sure where to put them.

DGRR 2016 here we come. Ugly.
