I am currently running a 3.4 with a CAI. Also, a 180 stat. I currently have HP Tuners so I can tune my computer. I wanted to know what is the next smaller pulley and if I am going to have to change my injectors?

Thanks

I wouldn't go farther with out rockers at least.

you will need rockers or a cam with stiffer valve springs and OR to go any lower pulley-wise. If you slap a smaller pulley on there now you will see massive KR and boost stack.

= KABOOM

Agreed, dont think about a 3.2 (safely) until you have headers and a cam. you wont need to change injectors until you get down to the 3.0 pulley size.

thanks for the information. I guess I will do the lifters next. What kind of cost and what lifters do you recommend?

?

Your stock lifters are fine up to about .530 valve lift (stock cam with 1.9 rockers is .490)

Sorry I meant what rockers should I get. Where can I buy them from?

Thanks
