Thread: About to order a BUNCH of stuff...need some opinions

Ok well I am about to order a bunch of stuff and the main question I have is...With an engine with just over 100k (very well maintained) be ok with a 3.2 with supporting mods? I know the varibles and everything on this but i'm talking more like can the stock head gaskets handle that much boost?? And if anyone can point out anything that i missed in my mod list like gaskets ect or other suggestions...LET ME KNOW!! Thanks fellas


ALL FROM ZZP
autolite 104's
aluminum 1.9 roller rocker package
comp cms 105 springs and retainers
zzp 3.2 mps
new belt for 3.2 pulley
fullsize intercooler
supercharger coupler
pacesetter coated headers
billet fuel rails
ported stock throttlebody
ported blower and lim


Just to let you guys know i may decide to get the billet throttlebody from zzp also instead of the stock ported...and i plan on getting the most out of the car with stock heads and cam....maybe some nos one day also

ok well i already have the valve cover gaskets but what makes the aluminum gaskets better...or are they??


And the tranny has been real good to me so far...no slipping or anything...yet

It's more important to get a good AFR and ~17 or 18* of timing and then find the right pulley to make those other two things happen without knock.

Well i'm also going to have a fullsize intercooler...witch i didnt see in your mod list...I have to pick a pulley size when ordering because there is no way i'm putting that press on 3.8 back on there....so thats why i went with the 3.2 as a starting point...good choice?

I'm running the plastic intake gaskets myself. Aluminum is better for long term, but I doubt my car will go that long without me ripping into the upper end anyway. I also don't run Dexcool, so one up for longevity.

Thanks, what about the stock head gaskets....What pulley size or boost psi do those hold up 2?

cool...what about the egr...i plan on deleating it so it wont clog the supercharger but how do i do so....Pcm and engine wise..just deleate the egr sensor from the pcm or disable the ses light? and what are some ways of blocking it off at the lim?

and also is there a way to replace the springs to 105's without removing the heads?? anyone ever done it on the 3800's before?


I know there is an air compressor fittng that screws into the spark plug hole...is that all i need? and a spring compressor? will any valve spring compressor work?

I'm running on FelPro gaskets right now. No idea what they can hold, but I'm fine right now.

Well i would like to remove it compleatly because of the ic install and it possibly clogging the ic. so as far as blocking anything off in the lim or headers or anything...what needs to be done?...i will take a look at the thread anyway...thanks

ZZP 78mm polished TB ordered
S/C coupler ordered
MPS 3.2 ordered

S/C is inlet is being ported to match the 78mm TB
S/C outlet is being ported as well
S/C is being polished and snout bearings replaced along with the installation of the mps and the coupler.

All the above work is being done by brian (AKA reptile)


I also just ordered ---


al-104's
stock modified rockers
comp cams #105 springs
comp cams retainers
comp cams valve locks
new belt for the 3.2
FS Intercooler
prj fuel logs
pacesetter coated headers


So once everything gets back from being ported and polished the build will begin...If any one has any tips or tricks about anything that is about to be done be sure to let me know...or if you think i forgot something. thanks
