Boosted 5.3 Hey Guys
Its been awhile since Ive been on. I have some questions hopefully ya'll can answer for me. Here is what i have, a 5.3 i purchased from the boneyard. I have completely disassembled it and its ready for the machine shop. I am going to be putting it in a 71 Chevelle. I am looking for a reliable 500rwhp. I am going be putting a turbo on it. I am also trying to do this on a budget. I would like some input on:
What cam (I was thinking LS6)
What heads (I was again thinking LS6)
What size turbo (I aint got no idea on this)
And what kind of boost I could run
Thanks any help would be greatly appreciated.
I will be keeping ya'll posted on the swap.

You dont need LS6 heads. maybe just LS1 heads, I have 6.0 heads it drops compression down to 8.6:1 but if your on a budget pass on the LS6 heads. You'll get beyond 500hp without them.
The Master Power T70 seems to be a good choice for the 5.3, people making over 600hp with them.
Mines a complete stock shortblock w/ 6.0l heads, Master power GT45 (kinda laggy) 15psi boost, 50 shot of spray, a cam i had laying around 224/224 112 and its been reliable for going on 3 years beating it pretty good. Makes about 640rwhp.
My friends BMW he put a 5.3 in it, budget build, 6.0 heads, MP T70, hasnt finished it yet though.

I made 490rwhp on 9lbs through a 4l80 unlocked 3500 stall, and have had it on 12lbs before. Stock long block with a GT2-3 cam. Granted I was doing all that on pump gas and lost a ringland, no reason why a forged bottom end wouldnt hold it all day.

Can anyone tell me if these will work on a 2002 5.3 with 2000 853 LS1 Heads? Why do they say 02-04 LS1?

yes they will work,, but i would go with mls head gasket.. muliti layered steel,,, hold up to a lot more power.. like 50 bucks a set.. at gm performance.com.. im running the 853 heads on my 5.3.. with ls6 cam. im at currently 13-14 psi,,with meth injection.. i did run out of injector with the 42lbs..i switch to 60lbs injectors.. i have no dyno numbers.. good luck..
