thanks for the help guys
btw i am in and around Jacksonville and Wilmington nc if u know a good shop to put this together let me know

 

Just use OEM honda

 

You will not find JDM B16 or ITR pistons oversized. I looked for days when I built my last GSR. Pr3's are your best bet for the most compression.

P30 pistons. Standard or oversized. $54 each.
Rings are another $32 per piston.

 

any problems with the pr3s on gsr rods and i only need .20 over

 

are thay the jdm ones or usdm ones

You want the motor to last 100,000 miles? Put stock VT in with R cams.

What bearings are you using?

 

OK, Let me clarify. in 81.5mm and up is what I was basing my stament off of. And holy ***** batman...$400 for a stock piston? No thanks. Buy a set of forged and pick your CR

 

USDM, but i have not found any documented difference between the two. Only heresay. The part # for the JDM pistons is 13020-P30-000.

 

Those are JDM P30's

 

The JDM P30 pistons and USDM PR3's are different if thats what you're referring to

 

honda OEM everything just the cam and valve springs are aftermarket and the ex valves witch are flat faced

 

i am with u i would get Nippon before spending 400 for pistons i am trying to do mostly OEM parts

 

Honestly I would run it at 81.5 or 82mm with PR3 pistons. I had that setup in my old car. 82mm GSR block crank and rods w/ pr3's, B16 head w/ ITR cams and a B16 tranny and it ran consistent 13.9's on street tires with 2.1 60's in a ex coupe that weighed almost 2600 with me in it. My CR was right at 11.4:1

 

thanks that was what i was looking for around there i was going to run blox type B's or skunk2 pro 1s. any problems with the pr3s someone on the form told me thay wareout faster cous of the small end of the gsr rod being smaller than the b16s

 

Tell that someone to go pack sand, that's the most moronic thing I have ever heard. My ran my GSR w/ B16 slugs for 25k and it was still going strong until the day it was stolen. You can't go wrong with more displacement and more compression, within reason of course.
As for cams....Unless you have a lot of stored knowledge somewhere, or have someone do the build and install for you, I would not touch the pro 1's. They are an animal all of themselves. Stick to the Skunk2 tuner lineup or somethijng similar, they are easy to tune and use and always deliver. Plus you WILL HAVE TO build your head to run anything of that nature. Do some searching and reading.

 

heads built valve springs new OEM intake valves port mached just looking for cams and i am going to have it put together by a machine shop that does Honda's and ill put it in and bring it to tune i have built a few Ford and chevy motors and a lot of honda bikes and one b18c1 just had itr pistons and cams i was just throwing out some ideas on a good mostly OEM build

 

To be 100% honest, putting in bigger cams and a bigger TB is nearly pointless with the P30 IM. Smallest Bvtec IM. All that air is just going to hit a bottle neck before it even gets to the cams to breathe. Look into a ITR or Skunk2 for your setup and that alone will free up HP not even cams will get you.

 

how about a blox or old str intake i have both in my shop
