Yea jspec.com or probably pandgarage.com can. You will have to call them and tell them what you want, then maybe wait weeks or months for them to go to or call there hook up in japan, find the part at an ok price then come back and sell it to you. Im sure there are some die hard CA fans over in japan. Like we have ka fans here lol. Minorities unite!!!
im sure he could do it for around that much. Get a leak down and compression test. FMU, mani, t25(or some other junkyard found turbo),dp,bov,exhaust. Shit you may not even need exhaust if your that tight on money. Atleast not right away. If you get what im saying. No intercooler, i would prolly just stay at 5 psi for insurance issues. It really depends on what you wanna risk lol. You could get a new fuel pump too. But i would be quick to upgrade as soon as possible. Like a safc or get a chip with maf and bigger injectors. Are you still saving and just want to get a small setup going for a "at the moment" setup, or is this all you really plan on doing? Cuz i would for sure just get a small intercooler and better fuel management and a tune of some sort. If thats all you plan on..then you can up dem psi's a bit too which is always a fun factor right!!
you could always gut your cat to, to help free up some flow since you have 2 1/4" stock pipes. It shouldnt be loud with out it anyways. Plus your turbo'd so exhaust db's go down naturally. Just make sure emissions test isnt coming up lol. But it may not matter.
*question* What else is done to your car?
