I need some engine mod guidance
I have posted asking something similar to this before, but I continuously fight with myself about which way to go for engine mods- boosted with H/C or just H/C. I have bought stuff to go one way, then decide a different route. I know I need to come up with a plan and stick with it, but as soon as I do, I change my mind a few days later. The car is not a racecar, but I do enjoy "spirited" driving and bragging rights. The car isn't a daily driver, but isn't a garage queen by any means.
I need some sensible reasoning to go one way or the other. I have most parts to go either way:
Boosted
Procharger P1SC
FMIC
Ported LS6 heads
comp cams blower cam(230ish/.570ish
Ls6 intake
Kooks Headers and X-pipe
KB BAP
42lb inj
N/A
Ported LS6 heads(might sell for TSP 5.3 stage 2)
TSP Torquer V2 cam(232/234, .595/.598)
LS6 intake(possible upgrade to FAST 90/90 if I go this route)
Kooks Headers and X-pipe

How much power do your want ?
That is what you have to ask yourself and then take it from there. I would try to get a ride in various guys cars before making up my mind.

. I am very indecisive. I was a little concerned about the added cylinder pressure of the S/C.I stopped into IPS Motorsports this morning and talked to the owner and he said that the P1SC should be fine. If I decide to go the N/A route, do you still happen to have those 5.3 heads?

Send the car to A&A or ECS and have them throw some boost on it. With either one of their kits you can get over 500 rwhp safely. I have the A&A kit on my 02 Z with 5 psi, it makes 540 rwhp, w/o meth.
I've always liked big cubes and staying N/A, although after having a few S/C'd cars there is nothing like it. IMO
It is a BLAST!

My concerns are keeping the engine together(of course), FMIC making the car run hot, more complex and added cost to tune.

Yeah, I know it is up to me. That is the problem . I am very indecisive.

If I decide to go the N/A route, do you still happen to have those 5.3 heads?The way I looked at NA vs SC was the same way I looked at the 4 wheel drive option when I bought my CTS. 4 wheel drive would be nice when I really needed it but I really don't need it that often. I don't want to drag the 4 wheel drive hardware around the 99.9% of the time I don't need it.
Just my $.02

As a matter of fact I do have the heads. A&A (West Coast Cylinder Heads) Stage 2 w/ Comp 921's)

What were the specs on the heads again?
I am pretty sure I would be happy with 460RWHP. What would I need to change in the N/A list to get that? Would your heads help over the ported LS6 heads?

Really depends on wether or not are six speed or auto. Give out point in Auto's is around 400 - 450 on stock parts. Six speed good to about 450 but needs an aftermarket clutch. Skip the new heads and cam and use that beef up drive train.

When I started my engine mods i just was planing on a cam and springs. But then all of the rest of the stuff I bought used form my buddies and ended up spending alot more than I thought. If I knew I was going to spend that much in the end I would of put a blower on it. But I love the idle.

My car is an MN6 and I'll probably run the current clutch until it goes, then upgrade. I already have the parts I have listed so to skip that step, I would have to sell everything and start all over. However, if I go with the N/A set-up, I may sell the P1SC kit which will free up a bit of cash for me.

So the more you throw at them the better they are!
So I slapped on a P1SC and picked it up to 591 RWHP! Now I'm satisfied and man it is a world of a difference and totally awesome!
7.6 PSI of B@@ST! on a 3.85" pulley and my H/C set-up!

right now, I am thinking of maybe beginning one of two ways
1. Install the ported LS6 heads and Torquer cam along with a 2pc timing cover. That way, I can change the cam fairly easily if I decide to add the P1SC.
or
2. Install the P1SC only and see if it is enough for me. then possibly sell everything else and beef up the drivetrain. i can then add a blower cam and heads if I feel the desire. Only issue I have with this route is that I won;t have the exhaust sound I want
