best years and models for spec e30?

[euroshark]

Just wanted to add two things:

In 88 the e engine did become the super eta, but only in the E28. The M20B27 stopped in the E30 chassis in 1987.

And in addition to having different heads, the eta and i motors also have different pistons, rods, and crankshafts, as well as different electronics.

an "eta" is the early model 84-87 m20b27 "e" engine (revs to 5k)

in 88 they made the "e" engine into a "super eta"

the "i" and the "e" engine have different heads, and they rev to different rpm's.

the "i" engine makes a lot more horsepower, and around the same amount of torque.

but only in the E28.

This is VERY incorrect. In 88 both the e30 and e28 got the super eta...

For real? I didn't see that in the books for some reason... Well, I stand corrected!

Edit: Something in my brain told me I had a 50/50 shot of being wrong... lol

Time for beer.
