But for your stock 5.3, I would get this and call it a day.

Trick Performance Products Turbo Kits

 

its not a 5.3 anymore

6.0 LY6

 

1st: Change ur sig.
2nd: Upgrade to stage-3 or 4..

 

whats the advantage of having two turbos insted of one?

from what I understand, twins spool faster and dont fall as fast as a single

so the power band is wider .

another quistion is , jurnal vs. ball bearing . whats the best for me?

I read in the BW catalog that both s300sx and s400sx are jurnal bearing and they do spool fast!

 

Just an FYI.
These primaries are larger than the 1 7/8" primaries on my other truck.
The tubing is thicker than 16g. Probably 14g stainless. Just estimating by holding a 12g 1 7/8" tube.
I had to enlarge one manifold bolt hole; just a tad too snug.
Other than that they fit fine and the rest is up to you.

 

man Im really considering buying these for a future twin build!!

 

good to hear this!! so they well withstand the weight of turbos and plumbing

i will be going turbo as soon as the funds allow me , what do you think i should go with ?
twins or singal?

 

I'm thinkin twins. But what A.R. would work with twins 68. AR on exhaust side and 70 on cold side?

 

I've got two GM4 turbo's from the 6.5 turbo diesel (for my 6.2L K5) but the thought of TTLQ4 was too enticing. I just jumped in here to say that these are smallish turbo's when used as singles but might work great as twins.
