Turbo manifold

[Si Speed 317]

Try a precision 5858 should get you to your power goal fairly Easyer. I run a 6262 and I'm around that power with 9 psi

I run a pt5558 .82 and manage 460fwhp at 1bar

Pretty much anything around gt30 sort of sizing works well

Both of these, well all 3, are great options. The goal here, [MENTION=1228]sstream[/MENTION], is to not barely make your power goal because your system will be limited in one or more aspects for the future when you want to make some more power. It will also result in parts not lasting as long/lack of safety for your motor. A GT30R, PT5558, PT5858, and even a 6262 will all hit your power goal and make over 500whp as well. And that's at less than 20psi for all of them (depending on supporting mods, of course). The importance is not the power you will make, but HOW you will make the power. If you use a little GT28R, which I had on my first build, you will have great mid-range power in your powerband but will be limited at the top end due to our higher redline. If you go with any of the 3 we all suggested, as examples, you will still have great power mid powerband but really pulls up top. And when you're racing/spirited driving, you're at the top of your powerband nearly the entire time.

I suggest a sidewinder or top-mount manifold for your setup. Do you know what is available around you? I KNOW we can make this setup work. The option [MENTION=1230]Gerry6262[/MENTION] could work: http://www.ebay.co.uk/itm/320781364573
