I finally made it to the track yesterday. I got passes and managed to go all the way down the track! lol. I've shot myself in the foot with the huge tires. The car bogs really bad on the launch but I still managed 11.94 at 117.8
That's on unleaded race gas and with the junk Holley! It's not a race carb with down leg boosters or a racing beat carb. Just a stock double pumper with a choke that I calibrated to run on the 13b. Car was really rich. Showing lambda of .87 at the start of each gear and .82 by the top of each gear.
I'd like to lean it out some and work on the launch. Not sure what more improvements I might get out of it. Still running split timing. I didn't try messing with any of that. Was just concerned at getting the cobwebs out and just actually going through the motions and making it down the track. I haven't made a pass in a decade.

Try installing a small jet in your flow control valve.
I'm down to a .019 from a .024. Was running a 6puk and now on a sintered disc. Had a .022 in it when it was doing the wheels up thing on the sintered disc. Now with the .019 the front wheels stay on the ground and it the cars feels so much more drivable. Still run very low 1.3 60 ft times.

You are using the Clutch Masters flow control valve? Where did you get the smaller jets? I called and they didn't have anything other than ones it came with (.050, .040, .030). I asked for blanks but they said they wouldn't sell those either.

What sensors did you have to add to go FI? i know the E&J takes a TPS. What else did you have to add? How does it run compared to the old Holley?

Then I got the Fueltech and rewired the whole car to have the Fueltech control the timing but still use the Holley for fuel delivery. I just wanted to see how fast I would go with the Holley on a Pport. The Fueltech controlling timing was a bit nicer than the locked distributor timing, and it had the really awesome side benefit of being a terrific datalogger. When I wired the car, I just wired it as if it already had fuel injectors and the various sensors. The injector harness uses a Deutsch connector to simply unplug from the rest of the main harness. So basically all I did was plug the tps in and plug in the injector harness when I bolted the E&J on.
The Fueltech will run the car with nothing more than a TPS and a crank sensor, but you can add all the other standard sensors to not only log, but you can have the Fueltech do various things based on what the sensor tells it (example: pull timing if water temp goes above a certain value).
Ive lit the car with the Fueltech and injectors, but somehow managed to get very unlucky and had a bad injector that would fire intermittently. That was tough to figure out. I ended up sending them to be flow tested to find that out. Ive ordered replacements, but haven't even tried lighting the car again yet. Its very loud so I usually tow the car somewhere out of town to mess with it.

Well I finally got around to putting a turbo on the RX3. I just turboed the 13b pport motor that was already in it. I tuned it myself and I have no idea what I’m doing lol. I’ve never done this before. I spent the afternoon on the dyno and never managed to turn the boost up. I started at 20psi and ended the day at 20psi. I only revved the motor to 9500, I’m just afraid to hurt it. The motor isn’t balanced or reinforced in any way and it’s 6 port plates.
I made 547 at 20psi (uncorrected. I live at 4200ft elevation but I’m not convinced that matters with a turbo). I’m hoping that I can tune more at the track and add maybe 5 or 10psi of boost to it with this motor. Who knows, I may have to go back to the dyno to dial it in more.
