If I get to the end of this NA build up, & find I'm still hungry for more powah, this diff's going to get replaced anyway. I can say, jumping from 3.9 to 4.3 gear makes a noticable difference in highway driving, even w/ an auto tranny. Yes, a manual swap is one of the items that will be part of this build up.
Nice, let me know how the car turns out after the swap.

I think that I'm leaning towards a Tii swap. I'll either take my chances w the compression or try to find one that has good comp. I'de like to get a miata diff in there too

Did the TII conversion.

I will never go back to NA unless it's a streetported 20b.

How much money do you have?

If you do have a little extra, do the TII swap, since despite what alot of people think, is MORE expensive then porting an NA. ****, a ported fresh NA is nearly the cost of alot of 'good' j-specs. (Check out Kevin Landers' site).

If you have the money to spend: Do a TII swap.
If you don't and just want a little extra pep: Stick with the NA and get a good port. Too many streetport jobs are these **** ports based off a TII port (which is different and if I remember correct, is what Argx has since last I heard Racing Beat doesn't sell NA templates).
