Turbo selection help. 4.8
I am currently starting a build of a 1987 Silverado. I will be using the tick performance stage 2 4.8/5.3 camshaft 219/223 , ls9 head gaskets, arp's, stock 4.8 bottom end with factory heads. I am having turbo selection issues. Any recommendations would be appreciated. Thanks for your time and help.

I run a Tc78 with a 68mm turbine on my 4.8 and like it a lot. I had a gt45 on it when I first put it together and it had a little to much lag for me. The 4.8 dosent have much *** outa boost and that with lag make for a lazy street car imo. I think this turbo would work well with your set up and cam.

Thought I saw a thread about the 80mm on here at some point. They seemed to be pretty bad as for the price but no first hand experience.

I have read and read until I was actually running circles. Lol. Lots to take in when you are new to turbos. I ordered a on3 7875 T4. Gonna give it a try as my first turbo build. Thank you for all the help. I will be posting a build thread the next few weeks.
