What I've done to my car this week!

[Richardnz]

I’m on my 3rd series 3 and all of them did it a bit. The only one that didn’t was my first 7, a series 2 that I had 25 years ago, I’ve never known why. I always just change gears and live with it. Any explanation would be welcome though.

Online some people suggest its the valve in the airbox which fails, although I'm not sure, I don't fully understand all the emissions gear anyway haha, I think a lot of what you read online is for USA versions which worked differently and had cats that needed to be kept at the right temperature, which of course UK cars never had and had a 79-80 style emissions gear throughout the model's life.

Interesting, KIMI 2 (S2) bucked very noticeably on throttle lift-off, and I couldn't find a solution, so normally just changed down a gear.

KIMI 3 (S3) does it too, but not so noticeably.

I think it's a fueling issue because non of the 5 Elford turbo equipped engines I've driven have bucked whereas quite a few of the Nikki equipped engines have done....some worse than others..... the Elfords seem a much smoother engine to drive

Have to say mine also does this, I've always thought it was the diff and was hoping to cure it when I fit my LSD, but reading through this thread it now appears it will not.

Moved them around and took this picture..... oh, and used Gus for work a couple of days last week

since I fried a bunch of stuff.. (about 3-4K worth) it is now parked till I decided what to do next...

tuner is talking AEM infinity, which would allow me to run 2 step, in gear boosting, on the fly map change, and once I have the 8.8 built I will also be able to setup traction control...

but for now...

I bought a replacement engine for the aging 12a.

The choice may offend some, so viewer discretion is advised.

Not a rotary, but still a good match for the car, all aluminium, 3.6l v6 with direct injection. Weight is comparable to a 13b turbo, but more than the 12a. The goal is to get it as low & far back as possible.

323hp in stock form, revs to 7200. Not as revvy as the 13b but the read line is basically the same as the 12a, should be a rocket with this much power in a lightweight chassis.
I was looking into staying rotary for a long time, but I just couldn't justify the kind of money that turbo engines are going for these days, & the Renesis would need an expensive aftermarket ECU to run or the cluster swapping in, and in the end it usually doesn't even dyno at its rated power.

Continuing on with my restoration of my 1985 RX7 GSL-SE I did the following.

Replaced burned out light bulbs in the HVAC logicon so when a button is selected the light above it lights. Mazda had 9 available left in inventory in North America. Bought 5 of them. The bases on the new lights did not fit for some reason so I had to remove the new lights from the new base and installed the new lights into the old base.

Replaced the the burned out back lighting to the rear defroster and hazard switches that flank each side of the instrument pod. Since Mazda does not make replacement bulbs for these switches and wants you to buy a whole new switch that is no longer available this repair involved unscrewing and removing the light located on the right side of the switch cluster that lights the two switches. Then removing the existing burned out back light from the light base and installing a #2174 wire base terminal light into the old base. Then reinstalling the light bulb back into the switch. Easy process.

My rear defroster switch was intermittent in operation. Disassembled the rear defroster switch and cleaned the switch contacts with DeoxIT 5% Spray Contact Cleaner and reassembled the switch.

Sent out the clock to get repaired. The clock was missing digits on the right side of the display. I tried to fix the clock by disassembling the clock and cleaning the clock display contacts but this did not fix the problem. Found a company called autoclockrepair.com that will fix the clock for 35 dollars and give a lifetime warranty. Currently waiting for the clock to come back.
