What should the next mod be for the most gain at the lowest cost?

I have done

1.6 RR, CAI, LTs, !cats, !muffler, Spec 3, Spec steel flywheel, nitrous, all the free mods, OBD1 covnersion, tuned, short throw, some other small crap.

anything else to do before I make the jump for a cam install?

 

How about a stronger rearend with gears if your budget allows, or just gears in general. Also, some rear suspension pieces like an adj. torque arm, lca's, a panhard rod, and some good tires will help.

 

I have some Kumo Excsta MXs their pretty sticky for a street tire, with some 18x9.5 C5 wheels. I also have DA Konis in back and SA Konis front with a strut tower brace...but thats all I have as far as suspenion goes. I would love to get a rearend...but from what I am seeing it will cost at least 2k and thats a bit steep for me right now. I would consider 373 gears, but from what I hear the bigger the gear the more fragile they are...and I don't want to risk a rearend rebuild right now.
