Sleeved B16, 81mm Pistons Low comp, thoughts?
My buddy has a sleeved b16 and crank for sale, for $900. I'm not sure who sleeved it, I believe benson.
Anyways, can I get some feedback on this potential setup? Goal is 500+whp.
B16 Sleeved block (81mm)
Eagle rods
CP low comp pistons
B16 head (stock TB, intake manifold)
B17 cams (I heard these are more aggressive than gsr cams?)
Precision 5857 billet wheel, .63 ar
1000cc injectors
water methanol injection
Large fmic
I plan to run as much boost as I can with this turbo. I have considered selling this turbo and going with something bigger, but if I do, I'm sure I'm going to max out my fuel pretty quickly.
These are the pistons, I am buying them from my friend as well, they are brand new. I believe these are 8:5:1 or 9:1? I'm not too sure.
Ideas, thoughts, criticism wanted!

B16 Sleeved block (81mm)
Eagle rods
CP low comp pistons --which is what compression?
B16 head (stock TB, intake manifold)
B17 cams (I heard these are more aggressive than gsr cams?) Umm.. no.
Precision 5857 billet wheel, .63 ar there's an entire thread on the capabilities of that turbocharger. About 560whp is all you'll get, so yes... 500+
1000cc injectors
water methanol injection Cool. Just use a single injector via the throttle body, and use good methanol
Large fmic Ok.. which large FMIC?

Depends upon the use of the car and turbocharger

Gotta stop buying parts from "buddies" who aren't sure of their own purchases, much less pushing them onto you to make a buck or two. So be sure. Know what you're getting .. k?

Be careful what you wish for.. you just might get it.

Re: Sleeved B16, 81mm Pistons Low comp, thoughts?
He said the pistons are 9:1 compression, would you say so? (pic in original post)
after this reading this table, it looks like the b17 cams and gsr cams (94+) are the same?
http://asian_e.tripod.com/Honda_Engine_Specs.htm
Should I tap the TB? is there a port I could use? I was told I could run the water/meth nozzle in the intake piping before the TB.
FMIC.. 31x12x3, ebay -_- but from what I researched, I should be okay. I know this isn't large compared to some out there.
Thanks for the feedback.

Part number and serial number will only tell you. just because it "looks" like its one compression, doesn't mean that it is. different cranks, rods, etc, will change that compression quickly. See if its 9.0:1 compression based upon a B16.

The B17 camshafts are no different than B16s.. you're wasting your time
Should I tap the TB? is there a port I could use? I was told I could run the water/meth nozzle in the intake piping before the TB.
Do NOT tap there. 3-6" before the TB into the I/C pipe. no direct port, no pre-turbo. Simplicity... Simplicity, Simplicity.

That actually is large, but the question is the amount of efficiency. In this case, only time will tell on that one.

Well I got these b17 cams with the b16 head I bought. Should I resell these and get gsr's? I don't have the money for a ITR valve train.
The pistons are connected to b16 rods. He was going throw them into the sleeved block, so I'm pretty sure its 9:1 with a b16 head, but I need to identify them some how.
Thanks again buddy!

). Scrounge up some money and get some GS-Rs and be done.

Re: Sleeved B16, 81mm Pistons Low comp, thoughts?
without the piston spec sheet from the manufacturer we can't tell you what compression ratio they will produce
flat tops are normally 10:1-11:1ish depending on things, the dis your pistons have look like a typical 9:1 piston but without that data sheet, who knows
there should be a part number on the pistons somewhere, this will allow the company to supply you with the data sheet, it's also the number they need should you ever have to order nee rings.

Re: Sleeved B16, 81mm Pistons Low comp, thoughts?
unless you plan on running a cam like the GSC T1s (great cam, they show great improvement on every setup I've seen them on) then the gsr cams are your best option. they are basically itr/ctr cams with less lift but the same duration.
I know people that are making 800+ on gsr cams, not saying that a good cam like what GSC offers wouldn't show a huge power improvement at that power level but it is proof that the gsrs can hold their own

What about valve train being used? Stated above that "You dont have money for ITR valvetrain." Were you talking about cams or the valvetrain itself (Springs, retainers, valves, ect.) I would highly suggest not to use the stock valvetrain if your goal is 500whp+.

Re: Sleeved B16, 81mm Pistons Low comp, thoughts?
i might have to put this in my sig wantboost.
Duration being the same is irrelivant. there are different lobe separations and lift its a totally different camshaft profile LOL SMH. Dont give off misinformation dude. the itr/ctr will outperform the gsr cams hands down. BUT the gsr cams will and have been known to make PLENTY of power.

Get some pistons with higher compression ratio. It will be a slug out of boost with 9:1. I know what your thinking, but safety is all in the tune.
