Hi.

I've been trying to decipher what kind of turbo would be the best match-up for my h22a, with moderate (around 5 or 6 psi) boost, and one having a boost threshold at around 4,000rpm, give or take.

I bought "Maximum Boost" by Corky Bell, and it has been quite helpful, but I get a bit lost in the "turbo selection" chapter..

Thanks in advance..
