turbo and non-turbo
 

have blown apex seals in rear section of my 86 rex(non-turbo)....what my question is; is interchanges??....have come accross many turbo II parts like housings,rotors, etc. will these parts interchange with a non-turbo??? and what size apex seals does a turbo run???.....2mm or 3mm.....

All Turbo II apex seals are identical (2mm). Housings and irons are interchangable.

The only things that aren't interchangable are the rotors, counterweight(s), and flywheel. Make certain to get the proper rotors, weights, or flywheel for your series (S4 = 87-88. S5=89-91). As long as you use parts from the same series and model (Turbo II; T-II's use different rotors, side irons, and flywheels than their NA counterparts), you can mix and match all you like.
