Hey, I picked this car up in early February and finally moved into a place with a garage so I can start working on it. It is a '93 with approximately 80k miles on it and an FMII kit and link. I have taken it to the track for a few sessions, but always ran into overheating issues a little ways into them. We originally suspected an issue with the cooling system, but after I pulled off the heat shield last weekend I noticed a massive exhaust leak at the exhaust manifold which I am very suspect of. Considering all of the coolant lines and heater core in its vicinity I think it might be my culprit. I am waiting to get a new gasket so I can get everything back together and try to get it out to the track again. At the least, fixing this leak should help me pick up good power (previously the car felt quick, but not as fast as it should have at ~14psi) and significantly reduce my spool up. The mod list is detailed below and since I have bought the car I have thrown on a set of wheels (the team dynamics ones that are on all the Spec cars) with shaved RA-1's and put in a Corbeau seat that I'm not terribly fond of.
Also, a friend is recomending I go with a liquid gasket rather than the OEM deal at the exhaust manifold... Does anyone have any experience with this?
This is my first Miata so take it easy on me! Previous cars were a T28 1.8t Audi A4, 20g wrx Sti, and a twin K04 Audi S4.
