I have a masterpower T70. My goal is to make 600 to 650hp. I know I can get this out of a 5.3L, however I don't want to be pushing the limits. Do you think it is okay to get this out of 5.3? Or should I get a 6.0? Please post your thoughts on how I can get this horsepower number... thanks

 

If I can get 400hp out of just the motor, I should be able to pull around 600 with about 8lbs. of boost. If I hit 600 with either one, what would you do to make it more reliable? I heard the rods are only good for around 500, so I'm planing to change those... anyone have an opinion on which motor I should use?

 

Read this... 600rwhp out of a stock 5.3 with only a 01 Z06 cam and a MP T-70 turbo

yeah, thats parish. They got those numbers with race gas and like 12lbs of boost or something like that... I forgot to mention that I only want to run around 8lbs.

 

okay so I'm leaning more towards the 6.0

should I run a ZO6 cam/springs like most do with the 5.3?

Is their anything I need to do to a 6.0 for it to run 8lbs? or is everything pretty solid for that low of boost?

 

10+ lbs here on a 212,6xx mile 5.3L
ran 8 lbs from 70k miles up to about a year ago...
only upgrade required will be injectors and fuel pump...IMO...

 

superado, what are you putting out hp wise?

 

i run between 9-12psi on a completely stock 6.0, just a cam. Im making about 670hp(crank). All you need is the zo6 cam and a fuel system and it will take alot. I dont even run a intercooler, just pump gas. If you can get a 6.0 cheap enough its a no-brainer, but the 5.3 is just so cheap its hard not to go that route.

Article I read said he bought a used Ls6 cam for 60 bucks.

 

I have a 5.3 I am currently building for a 1999 Camaro. I am going twins with LS6 cam and a good tune. I am shooting for 550HP!

 

parish used a ZO6 cam/springs and 50lb injectors

I can get a 6.0L for about $800 bucks... but I can get a 5.3L for a measly $400...

I'll prolly go with the same cam set-up, but I'm going to use 60lb injectors. Their 50pounders with at like 95% cycle duty!

so, here's the set-up so far: 6.0L with 60lb injectors, Z06 cam/springs, T70 turbo, 10.5lbs of boost, 93 octane.

should I go with a different set of rods? or will they be alright?

 

same thing?

 

yea they're the same... I was just listing his mods.....

anyway, will the rods be okay?

 

yes they should be ok...it's the piston(s) that will go IF anything...
there are guys running stock rods w/ forged pistons making damn good #'ers...

 

Ya, rods are plenty strong. I've seen 10 times more broken ringland from detention on stock boosted motors then broke rods. If my 4.8 can make 500+ at the wheels with 12 psi, pump gas and windshield washer fluid for meth, I think with 70 more cubes you should be able to get 600. Maybe not with 8 lbs, probable more like 10-12, but a stock motor and a Z06/LS6 cam with a good tune should hold it.

 

Any more info on stock rods and aftermarket pistons?

 

front or rear mount.

 

are you asking me buddy?
front mount, a lot like this

 

what should I do for a fuel system? 6.0L, 60lb injectors, T70 turbo.....

can I use the stock '93 v-6 camaro tank with a 'in tank' fuel pump (larger one of course) or should I sump the tank and put an in line pump on? I have no clue how big of one I need, so some gph numbers would help too...

 

Yeah guess I forgot the ?. Cant really help just was curios on your setup.
At least I got you a bump this evening.
