  1. You must have never heard Blitzvinning drive down pit road….
  2. I paid points for this exact swap, but if we can get a different interpretation then 25 points is 25 points I can use elsewhere.
  3. I think it is 7 with redundant relays. Still that seems a lot to me.
  4. I built an electric actuator for the variable intake when I installed the MS3Pro on my car. The bracket broke so I wired it open and couldn’t tell any difference at all, its intended to switch over around 3000 RPM and if you are driving a rotary at that low of an RPM on track you are not doing it right….. The best thing you can do to a rotary is to install a well mapped modern ECU, the fuel burn stays about the same but you get a lot more power for the fuel you do burn. Stock 80’s EFI goes crazy rich at high RPM’s on these cars.
  5. $80? I see about $500 worth of relays, circuit breakers, and switches in those pictures. Another thing I am working on is to simplify my car, I think I can get it down to 4 switches, start, run, wipers, cool suit. Those plus a push to talk on the wheel would seem to cover anything I would want to switch on or off in the car.
  6. Like everyone else I agree that it sounds like you have a blockage somewhere. I will give a nugget of advice that could save you from a lot of frustration down the line. When you install second gen rear brakes on a first gen car you have to flip them right for left. There is a R and L cast into the calipers but if you install them this way the bleed nipples will be pointing down and they will never bleed. I got lucky since I didn’t even notice the R and L in the calipers and just installed them with the bleed nipples up like any other caliper, but a friend of mine followed the marks and was really frustrated. The reason you have to do this is because on a second gen RX7 the rear calipers are mounted in front of the axle and on the first gen they are behind the axle.
  7. This is a perfect example to show why I will never build another car with relays and switches. https://ecumasterusa.com/products/ecumaster-pmu16-power-management-unit?variant=8318139269181 Up to 16 circuits fully programmable, communicates with the ECU over CAN so you can trigger things depending on inputs or conditions determined by the ECU. You can have up to 12 switches with only a 4 wire CAN connection to the box, I want simple and compact.
  8. I ran the Maxxis on my RX7, which weighs about the same as most Miata’s, back when they were the only 245-15 game in town. They worked very well on my car and we were able to set FTD at some tracks with them, the secret for a light car is very low pressures. I ran about 22-23 cold and not more than 28 hot, any more than that and the centers ran hot. One thing about the Maxxis is that it has a relatively deep tread depth, if you can get a set shaved down to 6/32 or 7/32 they would be less susceptible to chunking.
  9. You will have that problem no matter what until you lose one of the bars...
  10. BW supplies many modern OEM applications, generally it is pretty close between us and Honeywell as far as who is the largest turbo manufacturer and it varies by market. EFR turbos are made by BW, actually built here in our plant in Asheville. EFR turbos are not up to the same standard as a state of the art OEM turbo. Different auto manufacturers have different levels of turbo expertise, some are very good and some are working on it. Every program we work very closely with the manufacturer to develop the turbo exactly to their goals, some are more conservative and some are more aggressive to try new things. Auto manufacturers have looked into building their own turbos, but as far as I know they have all gone back to working with one of the 5 or so turbo companies out there.
  11. Plugged for racing, but very helpful for individual cylinder tuning. You would develop your base tune with a sensor in the downpipe, then install sensors one at a time for each cylinder to develop an individual cylinder trim for the base tune.
  12. Very true, the turbos that are available to most people are not very good, even EFR turbos are based on 30 year old aero. It is possible with a little work to fit a modern turbo onto an old engine…
  13. Na looks like standard recessed fender mount assemblies. https://www.summitracing.com/parts/jzp-350-250-03/overview/
  14. I disagree on this point, I always want my fuel fill port on the opposite side from the driver changes. If you ever watched the S10 guys fuel with the stock fill port located 6 inches behind the drivers door it was a nightmare, you had 3 guys just about rubbing shoulders and the fueling guy was always having to make room for the drivers getting in and out of the car.
