stanzione88

Hello im going to install my turbo kit this weekend on a stock b16a motor, and would like to know if there is going to be any benefit on installing GSR cams (no cam gears) on the stock head. I ask this because i already have the cams with me and the car is going to be tuned next week at lujan motorsport in Miami.

Im going to be using:
LOG MANIFOLD
60-1 TURBO
TIAL 38MM 0.7 BAR SPRING - 10psi
RC 750'S
2.5 INCH DP, 3 INCH EXHAUST NO CAT
2.5 INCH PIPING
PRECISION 600HP INTERCOOLER
OMNIPOWER MAP SENSOR
STOCK HEAD

Also tell me how much hp can i expect for, from what i have seen aroung it should be around 280whp.

Please let me know,

i think the set up sounds good execpt the 2.5" downpipe,i think that you will be held back by it.

Yes there will def be a difference. Some say up to 40hp on a boosted setup. Do some research theres plenty of comparisons out there. Check out evans-tuning dyno library. What are you running as engine management? I think 280 is about right. Thats a pretty big turbo for that kind of power, whats the a/r. But to tell you the truth I think the high revving b16 loves the bigger turbos

im running crome, turbo is .63 A/R.
what im most concerned of is that the valvetrain will be able to suppor the gsr cams...
I think 2.5 inch d/p will be good for now, i plan on adding some pistons and rods on january and turning up the boost.
Also can i run the b16 cam gear with gsr cams?

i think the jdm b16a cams a slight bigger then the gsr cams

stanzione88

i believe gsr cams are bigger than b16 cams, correct me if im wrong... thats why people upgrade from b16 to gsr cams.

jdm b16a cams off the sir2 are bigger than the gsr

JDM B16A SiR2:
Intake opening: 15
intake closing: 45
intake duration: 240
exhaust opening: 40
exhaust closing: 7
exhaust duration: 227
overlap: 22
intake valve lift (mm): 10.7
exhaust valve lift (mm): 9.4
intake/exhaust valve springs: Dual/Single

vs.

USDM B18C1:
Intake opening: 10
intake closing: 40
intake duration: 230
exhaust opening: 40
exhaust closing: 7
exhaust duration: 227
overlap: 17
intake valve lift (mm): 10.6
exhaust valve lift (mm): 9.4
intake/exhaust valve springs: Dual/Single

All cam timing figures are the high rpm lobe. All figures from Honda, which are based on 1 mm (.0394") lift at valve

I do have a siR II b16a, the one that comes with 170 hp... so b16a siR II Cams are better than gsr and i should not replace them if we go to the specs.

I read this article long before this thread, but I didnt know if there really was a difference in the USDM B16a cams and the JDM Sir II B16a cams. According to the chart above the JDM B16a cams have a higher duration for the intake opening/closing and for the exhaust opening/closing than the USDM GSR cams.........

But then again I really don't know what I am looking for with theses specs so I am most likely wrong but I had to ask

BrothaSit

you should be fine with your stock b16a cams...save up and get something better than gsr cams IMO
