Thread: running a 3.25" pulley

I have been following the thread about the ebay headers and want to buy them in the next day or so. I am not going to need a tune to run these headers correct? From my understanding these are just simple bolt on mods but please correct me if i am wrong. My goal is to run an 3.25" pulley and i have about 500 bucks now to start modding so i want to do that correctly. I plan on the headers, new colder spark plugs, wires, 180 t-stat, and FWI. Will those be enough mods to not have too much KR with a 3.25" pulley. Now, about KR, how do i measure how many degrees i have? Do i have to buy a scanner of some sort. If it makes any difference i work at a honda dealership so would they have any scanners i could use? and lastly, how do i go about getting my pcm tuned, that is, who is good, can i do it myself, etc.

yes that is what i have herd

You should really invest in a scanner like an Aeroforce so you can keep on eye on things all the time. No one can say whether or not you can run a 3.25 with the mods you listed. I highly doubt you can safely. You may want to add rockers and/or an intercooler to that list. As far as a tune try to find someone close to you that can tune it.

A decent cam would put you in the 3.25" pulley range perhaps.

an I/C would put you at 3"

Its been one of those days...

yea i wasnt sure if i was being a little to optimistic in hopeing that i could run a 3.25 with the mods i plan. i will just plan on running a 3.4 because i just want some more performance without having to blow to much coin...if it would take rockers or intercooling or camming it out to get to a 3.25 than that is a little more than i want to get into for now...it is my dd while i am in college so i just want it to be a little more fun till i get out of school nd can buy something i really want. Is it possible to do the mods i plan with the 3.4 for around 500 bucks?

hahaha that was what i was thinking too

thanks for all the help...however, no one addressed the issue if i am going to need a tune for the headers...which i am certain i dont but i just want to cover my bases....i am probably going to get the headers before i throw on a smaller pulley.

no tune needed for the headers, but one's needed/recommended for the pulley drop.
