New to k20's, looking to Turbo

[Si Speed 317]

Yea thats what the guy at compturbo said I needed. I thought a ct2 or ct3 5858, 6062, or 6262 would be plenty. And I plan on using the log mani for a while longer. I've seen them do fine up to 500hp. I'm just shooting for 400-430hp

Bad idea.

Please be aware your log manifold only has a t25 flange (very small) so that big turbo will not mount to that manifold and will not fit with an adaptor (would hit cowl) also those large turbos are designed for use with an external gate which your manifold doesn't have. And where have you seen log manifolds make 500hp on a k series?

And idt I have a boost leak. Pipes are welded. I just think that Dyno was garbage bc my car pulls a lot harder than 268. If I really have 268 than 400 will unbolt my damn seat

So if your pipes are welded, theres no chance of a leak? You yave no coupler connection points, no couplers for your intercooler? No vac lines?

What turbo manifold are you using? The leak could be in so many places, could be a loose coupler connection. Unless all your charge pipes are welded together? Which if they are, that's is honestly dumb as fuck...

Right, what manifold are you using? Pat, my .02 is that you're being cheap in the wrong ways. You cheaped out on a turbo. No bueno. But you not only cheaped out on a turbo, but a manifold too? And now you're willing to buy a big turbo (which needs a t4 single or twin scroll flange) on a smallsmallsmall T25 flange? Not to mention the turbo won't even fit

I very strongly suggest you rethink things. We're trying to help, and you're not listening very well. You get what you pay for in every aspect of life. There are budgets and ballers, but in the end there is one timeless concept that one should always abide to:

Fast - Reliable - Cheap.
Pick two.

If it' fast and cheap, it's not reliable. If it's reliable and cheap, it's not fast.
If it's fast and reliable, it's not cheap.
