Ok I知 new to the ls world and I figured this would b the place so I知 building a turboed luv with 5.3 btr stage 3cam 96 pound injectors gm performance valve spring and now I知 worried the turbo I have is not going to work my gol is 700hp I知 running water to air Intercooler so wuts the thoughts on this turbo will it get me there any advice is greatly appreciated
I am a newbie two turbos playing with 5.3 getting crammed into a Chevy luv i知 new to turbos I have a BTRstage 3cam gm performance valve springs 96pound injectors on3turbo 78-75 my goal is 800hp to wheels I can weld and fabricate I just never played with turbos with this turbo get me where I need to be or is the turbo to small
Does anybody have a turbo suggestion to run with that cam. I have already installed it in the motor and test started it so there痴 no way I can send it back
Rpm rang I知 not Sure what it will be going into is a 1972 Chevy luv Back by two speed powerglide the turbo specs are compressor Ar 80 and turbine ar.96 it痴 a on3 78\75 3inch exhaust with bosh1000cc injectors I have 2 walbro 450 fule pumps and btr stage 3cam I do not have a toqueconverter yet wut would happen if I use this turbo for now as starting out Thanks for the reply痴
I have no knowledge of turbos Other than you want the straightest path for oil drain and a good supply line of oil to the turbo I know nothing about compressor maps Do you have fabricating background and engine building I have just never played with turbos or any forced induction
I figured I壇 look here means it痴 an LS based motor and everybody seems to be quite well knowledgeable and anytime you go looking for anything on the Internet you see a lot of LS one tech sights given to healp find answers and so far everyone has Ben Quite helpful. It may seems that I may have to sell the turbo I have get a bigger one or buy the same thing and run twins I知 guessing. That or my other option is to stuff my stock truck cam back in my 5.3 and being my first turbo build I知 hoping some people will tell me do and donts with building a turbo motor
I know Horse power realize on cam what kind of power numbers when I start came with this turbo Mek could I get away with twin 78-75 or would it just b best to go with s400
What GM performance valve springs are you referring to?
I would just sell the cam and get a z06 cam for $100 and use the turbo you got.
If you start trying to get a turbo to match the cam you're gonna open a whole new can of worms. With a big enough turbo for that cam the boost is gonna come in way high in the rpm range, then you gotta build the rest of the motor and power train around that.. gears, stall, valve train, rod bolts for higher rpm etc etc.
It would be better to use the turbo you have and get the right cam than try to build everything to one wrong part.
