I was wondering how this setup would be if it were turbo charged my hp goal about 350
B16a block
Gsr head port and polished
Ctr pistons
H bean rods
Arp rod bolts
ARP head studs
Nippon racing rings
King bearings
.009 cometic head gasket
Ferrea flat valves
Skunk2 dual valve springs
Skunk2 titanium retainers
98+ ctr cams
Skunk2 intake manifold
Aem fuel rail
Aem fuel pressure regulator
750cc injectors
Walbro 255
b16 transmission
p28 with Crome chip or Hondata s100

 

looks good, might wanna change out pistons (i believe you need to anyhow with aftermarket rod) also no need for port./ thick head gasket/ aftermarket valves..........your goal will greatly depend on the turbo system itself

 

Yes CTR pistons are a no - no because of the very high compression ratio.
Get some nippon racing "turbo" pistons (pr4 type) for 350whp max or if you want more than that go for normal forged pistons from the big names.

 

If you going as far as rebuilding the bottom end, just save a little more and get a decent piston/rod combo. There are a lot of good packages that dont break the bank and then the rods or pistons won’t be that weak link anymore. Something like below is put together by a shop that knows they’re stuff and you know will work out fantastic. I just talked with them and the deal applies to the B16 also

High compression cast CTR pistons are terrible idea. S2 intake manifold, fuel rail, fuel pressure regulator, and port and polishing the head are not necessary. Re invest that money into more "required" areas of your build to make it more complete and reliable.

Flat faced valves aren't good for turbo engines. They're to bump compression on N/A setups.

Get something better than Crome. And no idea where you're getting the idea of trying to use S100.

Get proper forged pistons from CP, JE, Wiseco, Arias, or SpeedFactory. And get either Neptune RTP or Hondata S300 for tuning.

 

i agree , get a S300 and be done. Also save money on the port job and get better rods and pistons, I’m over 600whp on a stock gsr head

 

OP, WHY did you post this TWICE ?!?!? Please ask a MOD to merge both of your threads together. I responded in the other one.

 

Friend of mine did quite similar setup (by numbers), turned healthy B16 n/a to forced induction. But he was used forged pistons.

And even there, very stupid way to bump because it is increasing valvetrain mass, which is more critical factor than some minor change in static compression ratio value. Only place where these have theorical pros is the exhaust side, where the flat profile is helping for cylinder scavening. Sorry for OT.
