180whp will cost you a bit more then a grand.
I would suggest at the least, a 60 trim t3 for that. You would want a hybrid, one with a .48 a/r on the exhaust side... for the money it would cost to make one, you could get a t3/t4 50 trim, and make more power. *shrug*
Expect to pay 450 for a used 50 trim t3/t4.
You could easily get a cheapy DSM sidemount, wrap it up front and use heater hose from Amazon hoes, this will hold 8psi. Anything over, and it'll break. (personal expierence). 8psi should be good for some extra power. Around 170whp on a D series vtec engine. Very close to your goal. With some tuning and such you'll work great.

You will need injectors, 310cc recomended by me, an FMU and an S/VAFC for perfect fuel tuning.

no need for a walbro pump just yet.

Your most expensive items will be the

manifold, turbo and downpipe.

I could probably get in touch with my friend who makes manifolds in canada for right around 300 bucks shipped to your door. He is not a business, he just used to sell them on ebay.
