Engine is a stock '91 TII w/Mazda ECU, FCD, custom FMIC, Bosch 61975 fuel pump, 80mm DP, 3" exhaust. The air tube for the CAT is temporarily blocked (no CATs)....
Using probably the most inaccurate oil pressure gauge, the one in the dash ;-) I got: @ ~180 degree F oil temp ~20# @ idle ~60# > 3000 RPM (steady, on the...
Sounds like when the thermostat in the e-shaft nose opens, oil is bypassing the oil rings. Mileage? Could have weak oil ring springs or dead o-rings. I still...
The engine was "new" to me when I installed it... rumor had that it had ~12K on a rebuild. When I had the pan off, the claim appeared resonable... There is no...
I still have a set of '91 5 spoke GXL wheels for sale...ya cheep bastards ;) hehehehe Cory ... From: Randy To: RXTech@yahoogroups.com Sent: Friday, November...
I'm not 100% sure of this, but I think it's closed loop until you pass a certain TPS threshold (80%?), regardless of RPM, while the secondary injectors come on...
My guess is based on the S4 NA but since closed loop stops at 4000 RPM and the secondaries don't open until after 4000 RPM, I would say they are probably...
It's a decent question. I know my S5 went open loop at around 85 mph, which IIRC was about 3800 rpm and should have been when the secondaries kicked on. Never...
The S-3 (GSL-SE) ECU is only in closed loop at up to part throttle and up to 3800 rpm. The problem with running closed loop under heavy load is that the ...
I'll throw in my $0.02 since the scope of the thread has expanded to behavior of other generation RX-7's. ;) Here is a map of what the FD3S does in terms of...
I ran these tests myself on my S4. You can hook up an LED or lamp to the test connector to show rich cycling of closed loop. It's more difficult to read than...
Great chart! I'll have to see if I can find the respective S5 version... Based on all the feedback and my initial opinion, I'd say it's a bad idea to increase...
The new year is upon us. New Year's Eve is a time to celebrate the end of 2006 and the start of 2007. Balloon drops, champagne, music, and kissing that special...
Hi guys, Have an '86 GXL M/T and there's a rubbing-like noise coming from the rear end that is just driving me insane. Here's the story: 1. All of a sudden,...
I've read several articles over the years regarding Mazda's development efforts with hydrogen as a fuel. One indicated that the rotary engine seems to work...
I had a friend who had a propane turbo 12A in his Rx-7. At the time (mid '80s) it was one of the CA smog loopholes. It was a clean installation and from the...
I need some help on my Mazda History, so I thought I should go to the best source I could find, and that's the rotary community. So please, share your...

I don't know if this was a first or not, but the Mazda 626s of the '80s had a nifty rig where the dashboard vents oscillated back and forth. The term you may...
... That feature I don't remember, but I do remember my sister's '79 626 was the first 4 door car with trunk I ever saw to have the back seat halves fold down...
... I do remember the oscillating dashboard vents. My wife's '85 626 had them. I also remember the trunk lid came all the way down to the bumper. It made it...
Just wanted to say thank you to everyone who provided feedback about Mazda's innovations. The Mazda team was impressed with the message, and asked for a copy...
