Oops...was writing while the other post were up I guess. There are mainfolds around that would let you keep the AC. Think that
www.fullrace.com or whatever has some on their site that would let you keep it. But if you're wanting to go 10 psi I'd say go custom and get Hondata for an EMS (AEM EMS is way more expensive and I know a few people with it and they have nothing but problems.) And go with at least a T3/T4 turbo for good spool and boost, anything smaller wouldn't boost fully thru your rpms, i mean it'd max out too soon.
