H&C or ProCharger - Which one first? Poll
). Not sure what cam+heads to get with the procharger though. Below is what I currently have for the car. So what would some of you LS1 veterans do Procharger first, then H&C later? H&C first and procharger later? I'll worry about the trans, driveshaft, diff when i get there. I figure if my trans gives way then it's a perfect excuse to send it to FLT for rebuild to handle more power.
Car and Current Mods:
01 WS6 T/A 4AT 60K miles
-ARH LTH's w/ catted Y
-Magnaflow Catback
-FTP Lid
-Nitto 555r 275 front/315 rear
Mods in the Box (going on soon)
-UMI panhard bar - on car adjustable
-UMI LCA w/ relocation brackets
-UMI tunnel mount torque arm
-UMI subframe connectors
-Yank SS3600 torque converter
-B&M Trans Cooler
-KYB AGX front and rear shocks

i would highly suggest beefing up your tranny and rearend first that way it takes the abuse. makes no sense to spend X amount of cash to have your tranny give out during a tune or on the way back.. build your tranny and rear end to take the abuse.
but if i had to pick, i would definitely do a H/C setup first. its cheaper, plus depending on yourset you might be happy with the power it makes
Procharger -> beef up/rebuild trans and rear end -> H/C/I for more power. Only intend to run about 8lbs of boost.

I vote H/C because I have seen quite a few procharged cars making under 500. With the right H/C/I you will be making the same power with less issues due to boost, such as heat, extra crap all over the motor, weight etc etc...
Go with a big single turbo instead
Good luck keep us posted
Oh and if you are going to do it right match your heads to your cam get a good FI cam that will work well with the correct PC.

i would pull and sell or store the ls1.
and drop in a upgraded lq4 6.0
build your fuel system and drive train. for the abuse of forced induction.
the stock lq4 can handle 10psi on pump gas as is with correct tune and adequate fuel. and fmic. assuming the engine is healthy and low miles.
the 6.0 can also make more power than an equally prepared 5.7 ls1.

Those are very impressive numbers on a completely stock bottom en LS1. What it comes down to is tune. There is a lot more potential on the lq4 you are right, but if the op wants to use his fairly "new" ls1 then that is the way to go. I don't doubt your expertise or your knowledge on this but...this will save the OP a few dollars.
