Studs from the head to the manifold are most likely a different thread pitch then whats in the taco taco. I don't remember what my T3 tacotaco was but on a street car you should be fine using studs from ACE hardware.

I used some M8 studs I bought from autozone, with no problems. They had them in stock, they were a touch longer than needed but worked fine.

I was thinking about trying to take the car to a track day in the future. Was just curious if their was any inconel stuff available, I'll have to poke around some more.
anyway both pumps came in. The Amazon pump looked like it could fit but I had to return it asap. Got the plug and pump from priority Mazda. How should the plug be installed? Does it just pressure fit in?

Should give you an idea of the quality of the cheaper pump, also said made in Taiwan

I just sort of pressed the plug in then hit it with a hammer a few times.

Patsmx5 should be able to give you the specs for the t3 tacotaco manifold studs tomorrow when he gets his in. If you are even going to think about tracking the car. The TSE Inconel studs are the only ones you should be looking at. Savington was the first to the market with them, and is the only person who has proven them to work. It is one of the few products that I will not recommend getting from anyone else.

Hopefully savington has them in the right size. Also should I do the reroute?
Do you happen to know what size the plug for the wastegate signal line is for on the ebay turbos that you use? Hopefully switching that to the cold side should help with spool

No clue on plug size. I go to advance and buy a little pack of various sizes. Then I use that to plug things whenever i need plugs. Reroutes are good. I would recommend it if you can afford it. Not sure if there are any cheap spacers for sale currently.
