You have a Super Eta, like me.
Here's what I think you should do: Get the top end off of an I engine (head, throttle body, intake manifold) and slap it on the Super Eta Bottom end.
You're redline will raise to the redline of that of a 325i, and you'll have the torque of the eta.
Not only that, it's even more ideal for a turbo.
That's what I'll be doing, minus the turbo, since I don't have money for that.
I'm spending on my money on upgraded bushings, shocks, springs and the works. That will give me more fun.
I'll get to my car later, no time now.
OHH, by the way. There's no chip for the Super Eta
, so that ain't gonna happen. If you go the stroker route like I said above, you could throw in a 325i ECU, which is my plan, and get a Jim Conforti chip that you would normally get for an I engine.
Also, what "Racing seats" are you getting? Stock seats are heavy, but not getting true racing seats will not lighten your car much at all noticeable.
What have you done to lighten your car? Remove AC? Remove the tar from the pass compartment and trunk? No spare? What did you do?
What the hell are Cool Willy pads? They sound like a maker of frozen ice cream treats??
What are you replacing your fan with, since you're removing it?
