Hey guys so I am looking to modify my ALH 2003 Jetta I am about to weld a GT2056VK turbo to my OEM VNT15 manifold as I've seen that some kits are basically that and they want $1300.00USD for it. So my plans are since my VNT15 housing has been scrapped ever since I replaced the VNT15 core because of a stuck VNT and since I did that the exhaust housing was kinda rusted and a chunk around the cast manifold sealing surface chipped off with the turbo core. So I installed the new core I bought on ebay anyways and upon doing that had a major exhaust leak AT THE TURBO MANIFOLD and been driving around for a year with zero boost and like 50hp. So I finally had some time and picked up a KKK KP39 turbo from a BEW at a local scrap yard not far for the time being so I can still drive around while I attempt to weld the 2056 turbo I bought on ebay from a Mercedes Sprinter Van with the OM642 engine. I also will be fabricating a Darkside Development style race manifold from a extra ALH manifold I have.
So my question for tuning aspect is what program do i need to modify the tune on my engine ECU.
What size injector should I use with the GT2056VK turbo ? (I already have 205s is that big enough?)
What size exhaust. I was going to fabricate a 2.5" down with a 2.25" exhaust back to some kind of muffler.
Any of you have a recommendation for a front mount intercooler ? I assume I need a same side style of intercooler?
You can see how black this turbo was from the leaking exhaust housing
