see thats what im asking if i should skip the cam and get rockers first but also whats the largest rockers i could use now and with an aftermarket cam

Depends on the rockers and what cam you choose. Don't bother diving into the valvetrain until you realize what you want to do to the car. A cam will be fine enough without rockers. You need to decide on which cam first, and what your setup is going to be.

If you go with a GT2 cam or something, you cannot use high lift rockers. Same goes for boosted cams. Some guys run a VS with 1.7's on the intake side, but that is as high as it goes. The XP sticks with 1.6's.

ok then do you have ny idea where i should start looking for a centrafugal S/C setup

Zuul has the Novi kit on his car, and has been really pleased with it (as far as I know). He hasn't been around in a while, but you could PM him for some details. I have never dealt with one, I went with a Top-Swap instead.

ok thanks and i think i was talking to you about the TB spacer and the gasket from easyperformance i just installed the gasket and did a 60 mile round trip doing 80 when i got home i left my gp running and put my hand on the TB and it was cool to the touch my water temp gauge read a little over 180 at the same time

is it possible to replace the gen3 m90 with the gen5 version?

Yes, your TB will be colder, but JB welding the hole shut will accomplish the same thing.
Or you could do it the better way: http://www.grandprix.net/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=1;t=010841#000000

I just JB welded the hole, though.

yes but you need a different LIM than the one you have.

i have a n/a 3800 im just wondering if i could go straight with a gen5 now that ordonez got me stewing over whats next THANKS ALOT!!! jk lol

yes, as stated you will need a modded LIM... I'd suggest searching for more information.

ok ive decided way down the road i want a CSC kit besides a beefy tranny what else should i plan on getting b4 then

With the basic CSC kit, you won't even need a beefy tranny.

The VS cam goes very well with CSC too.

If I were in your shoes, amcsocold, I would sell the wizaired, MSD packs, and PCM. Call ZZP and see how much it would run for a novi 1000 setup. You can run GTP injectors.

i got the msd cause one of my coils went bad the wizaired box is sold and the pcm is custom tuned now

ok. well you won't need that particular custom tune or the wizaired with a turbo or centrifugal supercharger.

since this thread is about inj sizing,

what do people think of me upgrading to 42.5's i will be IC'd as well very soon and i just want to make sure im going to be able to drop pulley soon
