Brake booster solution I may have to mess around with different master cylinder boxes to get it dialed in. Its called a "super small booster", tuner people use them as a way to make room for turbos and ITBs. I haven't been able to find much info on properly setting it up on a miata yet, but I know its been done.
Years ago I was not impressed with the small diameter boosters, they didn't seem to help much. It was almost easier to modify the brake pedal ratio and go manual, but then again, its been a 'few' years, things have probably changed. You are progressing well. I'm betting that is going to be a fun ride.
Lesson learned: do not use aluminum for a shift linkage. I can not keep the jam nuts on the rod ends tight. Gonna have to get some steel round and try again. The muffler and exhaust tubing came in today. Looks like it's gonna work perfect. Waiting on V bands to come in, then I'll try my hand at mig welding stainless.
I called my welding salesman today. He says I could use the normal co2/argon mix but it wouldn't be that great. He said to use "tri gas" which i believe is argon helium and co2. Told him no way im buying a full bottle of the stuff just for a few small welds. He thinks he has a partially filled bottle he'll loan me.
Nobody should have this much fun with a rotten Datsun Tires may have been wider even if the width was the same. When it comes to width tire manufactures are a bit loose on what width is. Sometimes its actual tread width other times its sidewall width. Sometimes a tire manufacture will make cheater tires for a popular race cl***. That '245' tire might be closer to 255. If tread was worn down enough it may just be the illusion of a wider tire due to sidewall vs tread width.
