I have my Suzuki running pretty well. I hope to get a run or two this next week with the G-Tech on it to see what it will do. It feels like a 13 sec ride. With the NOS it should do 12's (YeHaw)... But I don't have my 6 ports hooked up yet (they are wired open) so it feels a little low short on power below 2500. It definately wants to pull right past the redline. With the 5.13 rear gears it's pretty quick shifting in 1st and 2nd. I broke my speedo cable last week so I have no sense of speed.



I was thinking about going with an electric speedometer, But according to AutoMeter, they don't make something that will work with the Mazda Transmission.



For those who haven't seen it.... Take a 1990 Suzuki Sidekick with a blown motor (They are known for spining bearings). Yank all the running gear and replace it with a 13B and transmission from a RX7. Well that's what I started a few years ago. I orginally was going to keep the 4 wheel drive and Mazda EFI electronics. But it was much easier to dump both.

Project Zuki

 

Good work. You may want to try VDO for a speedometer. Intellitronix(now Norksdog) makes sppedometers as well.

 

Either of these work with the Mazda Transmission?



I wanted to keep the factory gauges, but I think I am way beyond keeping it factory looking... I have a big ol' shift light on the dash with guages for my vitals (oil pressure, water temp and A/F mixture).



I decided today I will be looking for new seats.

 

If you want it to work you should be able to make it work. Most of those are universal. I've seen RX-7's with Autometer speedometers.

 

Probably the mechanical series. I emailed Autometer and they said they work with electronic sending units in most of the newer cars, They said if it has a cable drive they have a universal sending unit but it is not metric, which I assume the Mazda is.

 

You could probably rethread the hole for standard.

 

Well I drove down to a truck scale to get a weight of my Zuki. I was a little disapointed. 2400 lbs is the weight with 2/3 tank of gas and the hardtop on. I was hoping to be closer to 2200.



So now I am wondering, what is the weight of a RX7? Not the curb weight... but has anyone weighed theirs?



I had planed to make a few G-Tech runs, The damn thing wouldn't turn on. I checked the fuse and it was good. So I drove back and tried it in another car, still nothing. After about an hour I tried it again and it works. WTF



So maybe tomorrow I will get some decent runs. I plan to head to the local drags this summer (an hour a way) and get some good runs on the bottle. I'm shooting for a 12 sec 1/4. But I think I am dreaming as I am 200+ heaver than my projected weight.



Looks like 2003 will have to be the year of the Turbo for my little project.

 

Got my G-TECH working...



The Cigerette plug has 2 little plastic tabs on it. Not sure of their purpose but they lock the spring down and kep it from making contact. I cut them off and it works fine again.

 

The weight of a rx7 is anywhere from about 2600 lbs. to 3200 lbs depending on the year and model.

 

you probably started with a 160 horse motor if you got a 13b(stock).



Did you go with a Haltech and eliminate the AFM?



What kind of exhaust?



with minimal mods you should be able to get into the high 13's with the haltech and a good exhaust probably low 13's, maybe even low 12's with enough traction and good driving and a very well tuned engine.



Good Luck and sweet ride.
