looking for any free mods i can do to my 93 lt1. also i need opinions on CAI(ex. brand, wihch to stay away from) thanks.

 

Only one thats worth any time is the tb bypass. not free but costs like a dollar. As for the cai, just stay awat from the cheapo home made ones on ebay. lingenfelter is good, k&n, moroso, slp depending on what type of look you want as they are al pretty equal performance wise.

 

Use the the search button and type in free mods and you will come up with pages of stuff.

 

i like the moroso cai. how does tb bypass work? is it possible to port the throttle body at hpme or no?

 

moroso is good. you can port the tb but its usless unless you putting out 600 hp. the tb bypass involves disconnecting the coolant hoses from the tb and connecting them to 'bypass' the tb. Supposed to lower intake air temps since the hot coolant heats up the tb. i think throttle response improved a bit when i did it.

anyone have one of those? will that help?
im thinking of getting that when i get my intake and when i do the bypass and clean out my throttle body.

 

yes, TB airfoils are great. Try eBay, you can get one for a much better deal.

 

I would also buy a 160 t-stat and add a manual fan switch. That helped my car out.

 

if you can get an airfoil for like 10 -15 bucks go for it. if you pay any more youre just wasting money.

 

where do i get the vaccum caps for the tb? i went to lowes and couldnt find any..

 

You can get the caps at autozone they have rubber and another type. I got the "other type" thought they might last longer than the rubber and they are different colors, all though no one will see them anyway

 

whee done with tb bypass which took me about 20 minutes.
