East Tennessee Region SCCA

Works great when I can't see on my commute in the winter because my defroster doesn't work because I have no AC. Been there, done that.

I bought my miata with both high and low AC pressure the same. I got the r134a recovered and replaced the expansion valve and condenser first. That didn't fix it, so it was the compressor - I got a used one and put that in. I also replaced the receiver/drier and all of the relevant O-rings. I vacuum...

Fastech looks like they're worth checking out. Thanks!

I'm looking at megasquirt + turbo in the next year on my Miata. (I won't be autocrossing it.)

Are there any recommendations for a shop in town that knows how to do this sort of thing? I looked through the services recommendation sticky, but I'm looking for kind of a specific thing here.

Whoops: mods, I meant to put this in general not road racing.

I am nearly finished putting a junkyard engine in my 97, I kept everything straight but this. It's the bracket for the alternator and starter wiring. What does it bolt to?


Can't figure it out to save my life!

Yes, except oil pan on. Thanks for the tip Bob, but I ended up saving my sanity and grabbing a 350 lb-ft Kobalt electric impact from lowes for $150. Saved my sanity and helped me get a stuck caliper pin loose too!

I'm guessing no, but I need to pull the crankshaft bolt on an engine that's already on a stand without flywheel, I am trying to avoid the rope trick, and I'm trying to do it by Sunday. I'm referring to a tool like this: http://www.flyinmiata.com/index.php?deptid=5681&parentid=0&stocknumber=3...

Well... I realize this has no bearing on whether it's actually a bearing (I'm HILARIOUS) as I've been told by other people who know miatas better than me, but the compression test looks pretty good for a 16 year old engine. Spec according to haynes is 128psi minimum, 182 standard, 28psi max variance...

I'll definitely drop in a replacement over a rebuild, just because of cost. No garage until possibly Aug 9, so I'm twiddling my thumbs until then. https://www.youtube.com/watch?v=li2lQj1rHlo I dunno, quasi-internet-confirmed exhaust leak videos I've found sound similar. I'll also mention that I did ...

Thanks, really good to know! I have a truck, I'd rather just run and grab an engine to skip trying to ship it, I bet that's not cheap. A buddy of mine pointed out I could simply have an exhaust manifold leak screwing up the tune etc. I need to do a compression test and pull the exhaust manifold... W...

Yeah, it's sounding like dropping a new-to-me motor for the time being is the way to go. I think it's always been making this noise, but it was quieter before so I assumed it was HLA tick... the fact that it got louder is probably bad. I should hopefully have a garage after Aug 9, so I'll be able to...

I went to TGPR last weekend for a track day, and blew my radiator. It was on the start of the cooldown lap, I cruised in at like 2000RPM. Car definitely overheated, when I pulled into pit and came to a stop it died. I trailered it home. New radiator was put on tonight. That let me fill up the coolin...

Does ETR ever do this?

I sold my Rotrex-supercharged truck; I've got about 1/3 to 1/2 a bottle of Rotrex STX150 traction oil. It's backwards compatible as far as I know, and works with any Rotrex. This stuff is about $100/liter. I'll sell this partial bottle for $40 or so, you can use it to top up as you lose oil over time.
