Which Pulley and Plugs

[lawadm1]

2005 GTP

I'm installing ZZP headers and catted downpipe with 3in exit to ZZP resonator and ZZP catback, and I already have the CAI, and autolite 605's

With the above mods and stock pulley, should I stick with the autolite 605's, or can I go to the 104's?


Next up:
3.4 or 3.6 pulley?
Autolite 605 or 104 plugs?
stock or 180 tstat?


Anything else while I have everything torn apart?

I would probably go for a 3.5, I had the ZZP 3 inch DP and was seeing 6* of KR on a 3.5, until i started mixing e85. I doubt headers would eat more than 6 * of KR, but thats just my .02 Somone with more experience may be able to give a more definite answer.

I would run the 605's.

I like 180° t-stats because they keep the transmission cooler.

And you'll probably still have kr on the stock pulley from time to time. I'd leave the stock pulley on til you get some mods that make a difference.
