Need help piece turbo together

[Si Speed 317]

budget $4000 ...want to push around 300ish hp ...hopefully i can work something out with my direct port and still have my nitrous spraying til the turbo spool up..any thought and idea?

thanks for your time/help

Keeping spray and boosting is going to murder your 300who goal. Lol.

In all honesty I don't see that ending well for your stock pistons and or rods. You'll go through plugs left an right.

I didn't go turbo so I can't say what's your best route but I CAN say an external gated setup is way cooler. Lol

^ This.

And as Adam said, you're going to annihilate that goal of 300whp very easily. How much were you pushing with your direct-injection setup alone?

When you say "hopefully i can work something out with my direct port and still have my nitrous spraying til the turbo spool up", it made me realize something. With a small to mid size turbo (from a Greddy turbo to a GT30 or 5857) You'll spool stoopid fast. You won't even need the nitrous to support it. If you go with a 6262, then the bit of lag could be defeated with your nitrous, but even then you won't really need it. And, if you're using a 6262, you'll be able to push 500+whp without a sweat. And that's before nitrous, unless you only use nitrous to increase spool speed.

And it can be done for close to $4k, but that all depends on what setup you go with. Let's get some of this stuff answered and we'll go from there.
