winter project questions

**screamingreenmonster** · 10-29-2009

my plans are as follows for my gtp over the winter. I would like to put 1.9 ratios rockers in it intercooler it and possibly spary it with a little nitrous but i have a few questions

First with 1.9 ratio rocker whos are the best to buy and do i need anything else other than the rockers bolts and valve cover gaskets. One store buy valve springs andother store says you don;t have to if you not shifting over 6000 rpms.

Second with the intercooler wheres the best deal at for and intercooler. Zzp seems to be the most resonable as far as intercooler wise. Along with a inter cooler whats the lowest pulley size i can drop to with messing with injectors and **** like that. My car has cold air induction plugs wires msd coils headers 180 thermo 3.4 pulley custom tuned pcm and full exhuast with intercooler and rockers i should be able to run a 3.1 or 3.0 pulley right?

Finally nitrous yay or nay? im still up in the air about it. I really want to spray the car with 55 shot to get that instant boost of power but don't want to hurt anyhting internally either. 3800 performnace has a zex kit that sounds pretty safe and for the price seems very nice.

Any other mods you think i should do let me know

Thanks

Dan

How about posting in the right section to start?

And it is a supercharged car...you get full boost the second you stab into it...there is no waiting.

Just an FYI, when you're looking at going with a 3.0 or 3.1 pulley, you had better get yourself a set of bigger injectors. I made the mistake of not doing so, and I chipped 3 pistons. If you don't want to change injectors or risk blowing something up with your stock ones, don't go smaller than a 3.2.

Well...we can debate it like always you know...but I was running a 3.0" before the injectors went static...so I think that is another one of those...depends on the car deal.

But...I still wouldn't take any chances.

^ Agreed. He said he didn't want to mess with injectors or anything of the sort, so I figured I'd give the safest advice.

your gonna need fuel rails as well. At this point you might as well grab some 42#'s. I have 1.9 yella terra roller rockers and i like them. I'm running them with L76 valve springs, they seem to work well. There is a lot of debate on that. For $85 from the stealership, its not that bad.
