building a SR20 stroker, need some turbo advice.

[zavala]

hey everyone,
just looking for some insight on to what turbo might be the better for what I’m looking for. going to be using a Brian crower stroke kit with 86mm(bore)x91mm(stroke), now the whole point of me doing a stroker is to get rid of as much lag as I possibly can but still be able to run a decently big turbo. I’m been looking hard at the GT2871R and the GT3076R, wanting somewhere in the 400-450whp range with a really sickening spool. also should I go for internal or external waste gate for that much power? below is a list of what I’m working with so far so let me know what you think

list:
SR20det S13 red-top
BC 91mm stroker crank
BC econo rods
CP piston
BC 272/272 cam
BC stainless valves (stock size valves, anyone have any links to info about bigger valves?)
BC valve train kit
Greddy oil pan
"Jun style" intake manifold
850cc inject
ect.

the list goes on longer than that of course but that's pretty much the main things I’ve got going now. I know that it seems a bit extreme and expensive and that no normal car owner would take it upon himself to do this himself, but I’m a seasoned mechanic and own my own shop so feel free to let the technical jargon start flowing. thanks, Justin
