im thinking on buying a N/A FC for project but im unsure of a couple of things about FC´s



1. if any of the n/a fc has LSD witch one is the SE, GTU, GTX



2. if any of the FC bisides the turbo fc has 4 piston calipers SE, GTU,GTX



3. witch of the N/A fc weight less SE, GTU, GTX

 

The NA FC's that had a LSD are the GXL, GTU (series 4, 1986-1988), and GTUs (1989-1990). The GTX is a turbo model that wasnt available in the states, (i think anyway, ive never seen any here), but all turbos got an LSD. The S4's were clutch type, and the S5s were viscous type



Any RX-7 with the 5 lug brakes got the 4 piston calipers. series 4 GTU, series 5 GTUs, GXL, vert and turbo (i dont know about the rest of the s5's, like the SE)



The 86 and 87 sports weighed the least, and s4's weighed less than s5's. hope that helps

 

thanks that sureley cleared my question



now i really know what to look for on the market

 

1. the 86-88 gxl's and 89-90 gtu's have lsd.



2. the 86-87 sport, 88 gtu, 89-90 gtus, 86-90 gxl, all the verts, 91 coupe b package.



3. lightest is the 86-88 base model, heaviest is the 91 auto vert.... GT, GT limited, GTX and GTR are the models in japan. they are roughly equivalent to the us base, se, sport and gxl models, although they are all turbo

 

Not true. S5 GTU did not get 4-pots.
