If you want to stay N/A, your not gonna do it with out the PI Swap. Then Pullies, T/A, 4.10/4.30, LCA's, Springs, Longtubes, Offroad X pipe, struts, clutch, aluminum D/S and loose as much weight as you can on the car. As long as you practice there is no reason that combo cannot put you in the 12's on slicks, possibly DR's.
Your still restricted by the heads. Spend that money on heads first, then save up for a N.O.S. kit. Your still gonna be disapointed even on the bottle with those heads. Seriously the biggest improvment you can do to your car is PI heads.
I forgot to take pictures, but I simply wrapped a sturdy chain around the strut tower brace, and then bolted the chain to each cylinder head.
This provided ample support while the K-members were swapped.
Don't know if all STB's would be strong-enough though - the MM brace is pretty damn beefy.
Well did mine this past Sunday, it was pretty cool. I supported the stock K member with a jack and 2x4 and lowered the K with 2 other jacks. The new one lined up great with longtubes and all. Took about 5 hours taking our time.
