WTB Challenge Priced Intercooler, other various turbo parts

Looking to go from nitrous to turbo for the 2021 challenge and planning ahead. 

I need an intercooler for sure. One that can flow enough to support 600ish hp. Ideally one with a top outlet. 

Also need a wastegate. I have universal intercooler piping i got for free. But any piping with flanges attached that people want to give away or sell for cheap, ill take what i can get my hands on. 

Gt45 turbo. I can get one new on amazon for budget price but wont say no to a used one either to save money. 

I already have a set of factory ls manifolds i can weld some v bands to, but wouldnt say no to a good deal on some aftermarket manifolds. 

I will be at the challenge this year. I will have money on me so if you see this and want to clear out junk or give stuff away, Let me know. Thanks in advance!

I have a wastegate somewhere around here.  If I find it I'll bring it.

I also have the mother berker of all turbos.  I'll text you a picture so you can see if it'll work.  I think Patrick told me no LS could feed it.  Want to prove him wrong?

In reply to Stampie (FS) :

Let me know about the gate. interested. I am still thinking on the turbo. dont think it will work. but maybe with some help from spray.
