Currently working on a turbo build plan, I have a couple questions on what turbo and maybe head work if I need it. Let me break down what I have planned so far.

B18C1 sleeved to 84mm
B18C1 head mild PnP
OEM Crank balanced, polished, and WPC treated
SK2 intake manni port match to head
TB w/ TPS and 4bar 73mm tapered down to a 71mm
-plan on port matching the manni to TB also
SK2 Fuel rail
RC injectors size??? thinking 800?
Buddy club cam gears
Supertech spring&ret
Supertech Valves
Eagle rods
HKS BOV SQV
Mishimoto intercooler
Hondata s300
CP pistons 9.0cr

I was wondering what would be a good turbo more the specs a/r and trim. I was also thinking of over sizing my valves by .5. from what I understand that will be able to move more air in and out so allowing me to use a larger turbo with out creating too much lag??? I'm planning on custom pipes on the intercooler, downpipe, and turbo manni all the way out back.


I'm still looking into my other parts:
Oil catch can
Wastegate
Wideband AEM UEGO or Innovative
Fuel pressure reg.
Fuel pump

As far as the Turbo goes I was looking at a garrett gt3071r. I've been reading on the subject plenty but obviously not specific to my situation.

Thanks for the help ahead of time.
