Thank you for replying to a 10 year old thread.
I think the bottom line is, you can’t make it much better.
Wring her out in every gear and shift at red line, I don’t think you will really need a more.
My ‘85 feels like it has a turbo when I go wot at 6k to redline, the ‘91, not as much, but the 4v breaths better, and has better power already.
