i am putting a turbo on my 5.3 right now im am spinning 6700 on stock rod bolts should i get arps before i go boosted, i thought i was a good idea but i was reading another tread and a menber on here said it wasnt a good idea just wanted to get everyones opinion. motors stock rotating accembly and i plan on running 10-12# daily

 

Someone's gotta know if arps are good or not and why

 

Do you like spun rod bearings?? Many builds that use ARP rod bolts end in failure after few miles, unless you are planning on removing the engine and letting a race engine machine shop install the ARP bolts....I would leave the stock rod bolts in place.

 

I can agree. I always see people changing rod bolts. I feel that if the engine has any amount of miles on it, that is is broke in. Removing the stock bolts, even if 1 at a time will more then likely take the current load off the bearings, you will not get that back after you add the new bolts. What cam are you running to turn 6700, still make power, also what intake set up? Stock truck intake starts to fall off around 62ish. I would not spin it as hard. If it was getting fresh bearings, then that would be nice to know you had the added insurance. I say this alot, because I have seen it. Alot of other things take a **** before the rod bolts let loose.

 

im running a tbss intake with a 92mm throttle body and the cam is a 219-227 .609 .613 112 what should i turn the rpms down to with boost or just run what in doing now

 

normally your gonna shift out with boost alot lower..
but it depends on your turbo size and your exhaust, usually on a stock motor with a T4 turbo, say 76mm, 5500-6000 is gonna be good.

 

ya its a 76 with a 4 inch dp

 

I would bump the shift points down to 6200- 6400ish

 

still no on the arps then

 

It is 50/50, I think I would keep the stock ones in there, thats me though.
