Well looks like you forgot to INFORM us of what you really have.
$800 is cheap, even if a second hand HKS item (goodluck finding one at that price)
You could prob get a bush bearing turbo rebuilt for $1300
Or wait for a second hand Highflow to come along
but here ya go:
turbo kit
Turbo - buy lines, dump etc.
turbo
Stock turbo's don't "suck", many have lasted 250,000+km and 15years.
