best replacement would be a evo 3 16g turbo..
you can go cheap like this... https://www.amazon.com/Turbo-Turbocharg ... B00GTC0J18
or get a true oem one like this...https://www.extremepsi.com/store/produc ... t=0&page=1
first one is cheap china bay one.. some have ok luck with them.. some blow in first 50 miles... its a game of chance with them...
second one is a mhi.. which is a real replacement.. not a knockoff.. I have 1 of these on my 1.6 with a FP manifold.. works great... but I bought mine back in 04 when they first came out and only paid 550.. so they went up a lil but not too bad..
you can still find them for sale on tuners just make sure its the mhi one..
