Rite now im running 404's in my LS. basically i got the head done, and just need to do my bottom end cause its stock. I'm going to do an engine rebuild because my engines about done.

I was about to just sell my cams, and run simple LS turbo, but seeing nicklk running in the 12's on his 404 turbo, changed my mind, so ill be doing the same thing. My bro gets an employee discount at Honda so i'd love to use Honda parts to save alil cash. I just got a few questions though.

Pistons...? What should i get?? i was gonna use P30 pistons in my NA setup, but since im going turbo is that too much compression?? should i go for PR3's??

LS Rods and ARP Rod Bolts ok?? im only gonna be revving up to around 7500, maybe 8000 if i can.

Im only gonna be running around 6-9PSI, so what kind of turbo should i be looking into? cause im not looking to run high boost at all.

dont know of many people running this combination, so i'd like to get more info on this from the people that do know, thx

if you insist on running OEM pistons i would keep your stock LS pistons and boost on those. the lower the compression the more boost you can safley run on pump gas. just have your engine builder bore the cylinders and set the proper ring gaps for a turbo application.

but i would save up for some forged pistons and rods. boost is addicting and your gonna want more . and the more power you want to make the less chance your gonna brake something with good forged internals.

If your gonna go turbo, I would much rather spend the money on forged internals verse stock OEM, dont get me wrong OEM is good but for turbo, you will get addicted and the Highest Ive ever seen OEM internals go is about 10 psi and the piston cracked in about 2 weeks. Just spend the money on forged internals and pick a turbo for your powerband i.e lag and spool time and whatnot.

well, i'm probably not gonna run more than 8lbs of boost cause, ive yet to see anyone run that high on 404's. I'll idealy run 6lbs. nicklk is currently running 8lbs, but he's on forged internals.

i think he's running 10:5:1 compression, but wat will PR3's yield me in compression.

The 404 cams have great lift for turbo apps, they just have a little bit much as far as duration. However, you can dial out most of the over lap with a good set of cam gears, and make great power on them. You should leave more of the over lap if you plan on reving high, but the general rule of thumb is that the less overlap will make more power down low, and more overlap will make more power up high... For drag racing apps, I normally just worry about up high, being as you should be in the upper RPM range for the entire run...

Can i install the crower 402T's before im even boosting?? since i was gonna put in new valves,springs,retainers. And if i can how would my car run?? 00 LS

the 402T cams are designed more for boost, but will be fine all motor.... You will notice a power gain over stock due to the higher lift, but the benefit of the cams will be much more noticeable once you put some boost to it... No harm in installing them now tho
