It has always surprised me that the DE was up classed entirely.

I guess my view on the OEM 15HP difference even if widened to a 20HP difference in IT full build is that the full class up wasn't justified.

One explanation given to me was that at the time of classing DOHC was considered so high tech that it just had to be ITS. No idea if it was any basis or not.

I have been told that DOHC or not the throttle body housing is restrictive to ever experiencing the full benefits of the DE head. As well I have heard that there aren't any known S14's that can make ITS weight.

I am just curious with all the process activity why those running the DE in ITS wouldn't have asked for an ITA classing with a weight some X pounds over the E motor? Too heavy? Want to run the S chasis in ITS against the Mazdas and Bimmers anyway?

Just hypothetically what would the wieght of a KA24DE 240SX be under the new process if it was ITA instead?
