i have a chance to buy 2 60mm turbos for my 5.3. the exhaust are 1.15 . isn't that large? or would it just move the powerband up?

I'm no expert, but that seems pretty high....I'm doing twin 62s with an .8x A/R...i don't think your 5.3 can spin fast enough to get the full potential. But don't quote me on that, I'm still learning my self...

would i be better off with 1 then? this is all new to me also. also can you mix them, like 1 with a exhaust ar of 1 to have lowend and topend?

Those are big A/R's on the turbine housing especially if going twins. A MasterPower turbo is $699 brand new and has a 1 year warranty. A single MP T70 turbo on that 5.3 should put it into the 9's in a lightweight car with traction. Upgrade the cam and valvesprings while you are at it. Rod bolts as well if you got the extra funds.

Hmmm... good question, on one hand you have a 60mm turbo, which i see usually used in twin applications, but the AR is soo high that its hard to say when you see boost...

on a V configuration, no, but on a straight 6 thats typically what they do..

I love how people with no real knowledge on the subject always feel compelled to add their 2cents.

and it's lovely how you come in say something with no help added. But you would need to ask yourself where do you want you powerband. With an AR like that you will mostlikely see your boost and powerband near the top end range. Think of those highway supras. Check out the sponsors webpage (forcedinductions) and read up they have some helpful info on there but if you need to ask anyone try to get ahold of Jose on here to get some help. He is wondering around on here somewhere
