Okay, here we go. I'm having a B20 built to handle up to 700hp. My goal is 550hp but i had it built for 700 to be on the safe side or in case i want to boost a little more. I'm wondering if you all can give me your suggestions on a few turbo's. I don't want to have to boost over 40psi but I want as minimal turbo lag as possible so I can utilize a wider powerband from the turbo. All suggestions for my setup will be appreciated.

 

The precision website says the SC61 is rated up to 680HP, that seems to be in your range.

 

holy ****, let's hope you don't have to boost over 40 psi. what kind of engine management will you be using?

 

Hondata for engine management. Also, I don't want to go with the SC-61 because from what I've read, you don't reach full boost until your about to shift. And thats on v-tec setups. <----- correct me if im wrong

 

Maybe a T3/T4 with like a .60 compressor AR and a .48 turbine AR

 

Oh yeah, btw, my C/R is 10.4:1. Any other suggestions?

 

Why not go standalone? Hondata is a great tuning device but to get the best power off of less boost you need better management. I suggest getting a standalone such as AEM EMS.
40 psi will give you well over what you are looking for. Don't get ahead of yourself. Make sure you do alot of research before moving forward.

many will disagree with this, but lets not get into that discussion.

I have an EMS, but haven't installed it yet so I can't give my .02 on it.

From what i've read Hondata and the AEM are very comparable.

 

your b20 will have no problem hitting 20-25psi before 5500 on a sc61 which gives u plenty of room for a decent powerband

this is not accurate. i get full boost by 4500 (10psi).

 

i good equal length manifold and properly sized downpipe can reduce spools times as much as 700-800rpm lower also
