as long as its starts 2 spool at 3000rpm theres nothing wrong with that, if it starts 2 spool at 4000rpm, i would go insane personally.
You bought a cheap turbo, dont expect 2 much bang out of it, if u want 220-230rwkw go for a gt2530. but u would have to go back to the factory manifold or get a adapter made up as you have the hks t04e manifld made for the rb20/25det.
With people with the hks manifold, did it fit stright in as in you didnt have to remove anything 2 fit it in
as in aircon!
anything above .64 on an exhaust housing is too big for a 2L.
