im information hungry on the 1990 year for the GTUs. Im fixin to buy one here soon... as soon as the money comes in and i wanna find out everything i can... im psyched about gettin this car cuz i know its THE Rarest RX7 to hit US soil...

Um, what do you want to know? They are NA FCs basically. Just a rare model. I believe they have suspension like TIIs (LSD) and aluminum hoods on all of them, but thats all. Also they only came in red, white, and black.

yea, i konw a guy in west palm who is selling one.. the body is rough on the pass side cuz someone side swiped it in a parking garage, but im not worried about it.

I guess i know everything there is to know already:

1990- only 100 units admittedly produced

smooth case NA tranny (not T2 tranny)
revised 5th gear ratio (shorter than other NA's)
4.30 Viscous LSD rear end (GTUs only)
Crank windows
Manual locks
No-tilt steering
Power steering
No factory sun roof
Factory Aluminum Hood
T2 16x7 Mesh wheels
Cloth interior only
No rear seat
AC optional
No rear wiper
Tire inflation sticker on door jamb recommends "205/50/R16" tires.

thats all i can think of right now. apparantly they produced the GTUs model to celebrate their huge winning streak that began in 1979? in the IMSA/GTU manufacturer's class with consecutive wins. the GTUs apparantly could only be had by selecting a combination of option and wasnt a model trim discussed anywhere in the dealer literature (That i have seen so far). In 1989 and 1990, the only trim levels discussed are the GTU (base model), TurboII and Convertible that i have seen in the RX7 Owners manual.

in 1990, i undestand that they only produced 100 units because that was the required amount of units to be produced in order for Mazda to be eligible to compete in the IMSA GTU class of the Manufacturer championship... a Homologation series. I guess 1990 season was the last year they competed in the IMSA GTU series.

Anyone else think of anything i forgot?

also the rotors are TII rotors but lighter

Solar Specialist

I do not believe so. That would mean it had lower compression and thus, less HP than other NAs of the same year.

MATHIS

From What I know is that the rotors are forged and weigh .2 lighter theirfore most racers use the engine to run higher boost or nitrous

Solar Specialist

The GTUs has the same exact engine as the other NAs from S5. They all put out 160bhp stock.

MATHIS

check with kilo he said something else

seventhgear

im with ryde or die.. all s5 engines had lighter rotors than s4 rotors.... yet i do not think there is a difference in any s5 rotors. no that i have seen or heard of.
