Competition comparable physical size turbo?

[GOTSOOT]

What turbo would be a good replacement physically for a set of PDR twins using an HX-40-HT3b replacing the 40 for the top turbo. I beleive that their is enough play in both the hot and cold pipes to allow for some differences. thanx thinking a HTT HTB2?

bubba-
any complaints? how does the H2E flow?

I know the H2E does work on the ol' 7. 3 Powerstrokes

An H2E is close to a Hx52 i belive. I used an HT60 for the large charger on mine. It flows a bit more air than a HT3B. I like it so far but Im still testing stuff.
