Easy Greg. You should know about the Miata's before you freak out. The 94-97 motors are IDENTICAL. When you order a crate from Mazda, you get the same thing for any of those years - from oil pan to head... the ONLY difference in the cars is the change from OBD-1 to OBD-2. It's 100% software.

Since this modification is legal in IT, there is effectively ZERO difference in the cars in IT-prep.

On edit: Talking with Bowie Grey and Mike VanSteenburg on the 1.6 vs. the 1.8 - neither can decide which one they would think will be better. Bowie chose to rebuild his 1.6 instead of building a 1.8 and Mike told me just yesterday that he thinks his 1.6 will PROBABLY turn out to be the better racecar.

Um...HUH??? OBD-1 and OBD-2 cars are very different with an open ecu rule. 2380 no restrictor 040 over header intake really good brakes really good suspension hoosiers oh and rear wheel drive...so why is my integra 215# heavier??? I have been racing SM for a few races now and the top guys are turning laps close, but not better than top ITA times...in a SS type class! Imagine if the effort was put forth on those cars for A. I am bolting lead to my car...staring at my SM...thinking...
