Im looking for 400 - 450hp to the wheels on a stock block with no more then 15 - 17psi. Can this be done? If so, what turbo will be the best considering my power goals and supporting mods listed below. Id like as much low end power as possible without sacrificing my power goals. I know...I know...Im trying to have my cake and eat it too. Any help is appreciated.

maybe A-Spec's 500R...closer to the 400 number

 

^Sounds like a good guess to me. The 500r did 448@14psi with a large street port. So 400@14-16psi is probably easily within range for stock ports. pwwatkins just got a 500r installed and tuned on his car with stock ports. After some calulations he came up with aprox 405hp not sure what boost setting though, either 13 or 17 psi not dyno confirmed though.

 

Yeah, that was just the rx7.com fuel calc. I'm hitting 1.1 bar. I will get some dyno numbers in a little less than a month, once I get the twin power. I ordered the twin power from widegtr about 2 months ago and am still waiting.
