I have a 88 GTU and bout to purchase a 89 RX-7.. I have a good feeling that its GTU also.. how can u tell that its a GTU? second question.. assuming that its a GTU what is the difference between a S5 and S4 GTU? any significant increase in power..... i heard that S5 engines have lighter rotors... is that true or a myth? https://www.nopistons.com/forums/pub...#>/biggrin.png

the 88 gtu is a base car with turbo seats and mirrors.



in 89 the gtu is a base model. but in 89 you get the 160hp engine with lighter rotors, power windows, power steering.

so theres nothin really special wit the 88 GTU but mazda went further wit the 89 GTU.... hmm what if the 89 don't have power windows is it still a GTU??

88 GTU is the base model with all the good performance stuff, 4 piston calipers, vented rear rotors, slightly stiffer suspension, different gear ratios, lsd, cool interior, etc.



89 GTU is the plane jane base model, no lsd, but Mazda made a bunch of stuff standard equipment in the S5's.



There is the GTUs wich is the same concept as the 88 GTU.....

15" alloy wheels, cool spoiler, a nicer interior, anti-theft alarm, some say power windows and stuff, but my boys 90 GTU didn't have power windows, also I believe sunroofs were made standard....



Def no LSD on the S5 GTU

Just get a diff from an S4 GXL, it's good clutch type LSD, and it's a straightforward swap.
