I just bought a 99 gtp and it has 1.6 roller rockers...i want to upgrade to a 1.8 but i want to know how difficult it would be and if i should invest is push rods or would it be alright with the stock ones?

they are super easy to change. If you pull your sc you could port it out too.

if i did get my supercharger ported where would be a good place to have it done. I live in Abilene, KS is there anywhere close? and how much do you think it would cost me?

How do you know the car has 1.6 rollers?
If you're positive, does the car have any other modifications?
01-14-2012
port your sc yourself it'll only cost you about $10-20 for bits and everything

Receipt for parts and shop....it also has cold air intake headers cat back exhaust and high flow cats and plug wires....I don't know how to port it

Putting stock rockers on would be the biggest upgrade you could do short of modded stock rockers.

What else would I have to do to put 1.8's on it?

I suggest re-reading darkhorizon's post. IMHO it wouldn't be worth your time to do it, unless you got a geat deal on some roller rocker 1.9's for it. Even then gains would only be decent. I only have HS 1.9's on the car because they were already on the car when I bought it. If the rockers were stock I'd have just bought modd'ed ones or looking into a cam swap.

Well I don't feel like pulling the whole engine so I think i will just leave it be...thanks for all the help everyone
01-16-2012
why pull motor?
01-16-2012
because rockers and springs...
....donny.
01-16-2012
What car is this in?
01-17-2012
99 gtp
01-17-2012
Then why would you have to pull the motor?
Alt, belts, tensioner, coil bracket.
Maybe a few brackets for some sensors on the back side.
Other than that, theres nothing in your way.

I would have room to get the cam out? And get a new one in without pulling the engine? This doesn't seem to make sense
01-18-2012
Why do you have to pull the cam to change the rockers?
01-18-2012
I think he's on the subject of cam swaping, I think. If that's the case plenty of members have lowered the cradle, pulled the cover off and swapped the cam.
01-18-2012
That's what I was talkin about and do you have instructions for that?
