(1) Performance as defined by either power or effect on power
(2) Hypothetical comparison of $/power between $100 muffler and $500 cat-back
(3) Some of these might be somewhat more effective ONLY when all previous bolt-ons have been executed

** (Of course a Turbo or VE are higher performance value than all bolt-ons)

Great places to search are this forum, www.se-r.net, the old SE-R Mailing List, and that other forum.

(At the time some links go to sr20forum, sorry 'bout that)

what is the wayne cox hp trick?? i never herd of such a thing.

Dont forget the best mod. Walbro 255lph pump. Since 90% of the factory pumps fail prematurely cuasing down right dodgy performance.

Thanks for the great info, I should probably get one

That really is a grey area of maintenance, if we're talking NA DE (which we are). A baseline tune-up is a given, also.

:oDon't know what you mean.

nice thread

I'm going to add hyperlinks to content, and would a good thread to redirect newbies, esp. if it were stickied.

That would be nice

Hasn't this thread been stickied already?
