hey does any one knw the weight of a standard series 1 (1st Generation) rx7?? and wot can be done to make them lighter for street and hw to mount a 13B-REW in to one

 

It's around 2300 lbs.

You need to find a way to locate the engine mount on the REW from the rear end plate to the front end plate. This WILL be custom, and nobody sells something like that. Or, measure the difference in distance from where the stock location is on the motor, to where it needs to be, and weld some mounts on the unibody rails.

i hope that made sense, i'm tired.

But yes, I've got a friend with an itchin to try this. And he's got everything to do it, since a 20B now resides under the hood of his FD.

 

I know I have an S2, but my title says 2360, if that's any help
