52mm turbos? I thought the ebay gt45 was a 69mm turbo with a 1.05a/r t4 housing

denmah used a gt35 ebay turbo in twin setup and was too small. IMO this turbos are to small. Not sure on the power your looking to make tho.



Denmah made like 500whp and 820tq and like 15psi on the white 2500LD

ebay gt45 specs. If you building a max effort build then the ebay gt45 will be what you need a twin setup. And a 3-12 cam would do a hell of alot better the any stock cam.

What kinda power you trying to make?

I had the same turbos denmah used. I ran like 20 degrees timing and was over boosting in the 25-30psi range and running lean. It honestly felt like a big block. It's instant power it's rediculous. Those were 61mm comp and 62mm turbine. For your 5.3 the cx racing gt35's will work out good. I wouldn't get those gt45's you posted. It honestly depends on the power you want to make and what you want to do with the truck. If I were you I would get the on3 70mm turbos in .68 ar and get cam and converter made for you so spool doesn't suck.

6-650 max

6-650 max can I get that? Gonna be running twins with intercooler

Those cx racing gt35's will work out good for you then. Just keep stock cam or ls6, ls9 it don't matter it will spool fast either way

smokeshow

iTrader: (17)

This information is misleading. I made twice the power on the same boost, same turbos and same engine. There were other issues with his setup.

rollwithit

What cam did you run?

iTrader: (3)

Yea he had a big tick cam and ran the turbos to hard on the 6.0

Once again, this is not a eBay gt45 turbo... different specs. My a/r is 0.68 the specs you listed are different than mine. And the other guy, its not a gt35 either.. were discussing a t4-.68 a/r gt45
