I have a 93 z and was wondering what are some basic free mods that i can do to the motor that will have a decent hp gain ?

 

tb coolant bypass is one, supposedly b/c the tb doesnt get that hot as when there was coolant flowing thru it, you get cooler air into the engine. which helps net some hp

 

relocate the IAT to the end of the air filter
port/polish/descreen MAF (controversial) i did mine???
remove AIR/EGR emission (no HP gains just clears up engine bay)
remove cats put a straight pipe in place of it.
cold air induction if your really creative
remove front swaybar (drag racing only, not x cross)
and of course the most effective; weight removal

 

**relocate the IAT to the end of the air filter**
Is that the Air Temp sensor,.? If so where do we locate it? Noticable difference ?

 

well first off he doesn't have a maf sensor to port...it's a 93

now then

moving the iac closer to the filter will not really pick up any hp from all that i've read about it (seen it on 3rd gens, and 4th gens), but i does supposedly give crisper throttle response. the idea behind it is to give a "true-er" reading of the air coming in before it gets heated by the intake. this theoretically give more power (real world maybe 1hp).


the tb bypass is a good mod in genereal specially combined with a $15 160 degree thermostat to lower engine running temps and then redirect the coolant through the tb to prevent heat soak

if you are interested i have a 160* thermostat and a set of underdrive pullies from my totalled 96z. i could give you a good deal on them for a nice cheap boost. check out my "for sale" page on my web site in the sig.

 

sorry about that didnt realize it was 93 until now....
