here is my build then ill get to question.
p75 head port matched to s2 im and 3angle valve job
s2 im
hondata im gasket
crower valve train with 404's
buddy club cam gears
440cc injectors
68 mm tb
str fuel rail and fpr
balanced and polished crank
stock rods polished and shot peened
block guard
11lbs flywheel
stage 2 clutch
ctr crank pully
arp hardware
block bored 20 over
4-1 race header 2.5" stright through exhaust
the question is iv looked at 3 compression calaculators there all diff, looking for 12:1 cr. i have been told go with ptc pistons, i also been told p73 jdm pistons, give me imput because on the calc's there diff ranging from 11:1-13.5:1.any POSITIVE info would be great

tb no, injectors no, and ctr pistons no... and since your boring 20 over just run srp 10.5:1 pistons since they are common in that bore size. everything else you have there is close to my setup and for what it is moves...props for doing this build
Starrfire
01-17-2010, 10:13 AM
use jdm b16a pistons, p30's make more compression than jdm itr's but less than b16b's.
11.7:1 at 81.5mm bore. stock injectors will work fine. Throttle body is iffy. 65 mm would be the largest I would go on a mild setup like this.
cprtyler
01-17-2010, 11:27 PM
ok so p30's put compression at 11.7:1 thats close to what i want any other suggestions as fuel pump and ignition?

im figuring around 150-165 hp (trying to keep realistic numbers in mind) i already have a turbo lsv in makes also, but with this build its something not many ppl do, right now till i can up grade i have a hydro ls tranny but when i get funds ill get a lsd type r (atleast thats what i want). the reason i was wondering about ignition set up is because my car was acting funny when i had platium ngk plug in the car, i put ngk copper in it and ran great, the pulse star plugs (which are amazing in my other car) are platium. i checked both gaps on both plugs and it was same cap,rotor,and wires. do u think a accel coil or msd box would suffice? i would like more numbers around 180 but still wanna use 92 octain if any one has any more suggestions lmk

Starrfire

Also what you don't need is the rods shot peened and polished, but ARP does recommend you get the big end re sized. I did per their reccomendation.
Balancing is a good thing though, just make sure you have everything in the rotating assembly, well minus the clutch and flywheel for obvious reasons(out of balance possibly with the change of a clutch/flywheel selection). Just make sure you have your pistons,rings,crank gear, crank pulley and bolt and you should be gravy. GL with the build. It should go smoothly since its a really simple engine.

all piston brands are common in that bore size.
I would save money on said parts and get some forged 12:1 pistons. Then you wont have to calculate your CR and you wont have to worry about weak pistons. MAHLE makes some nice b18 high compression pistons
cprtyler
01-18-2010, 11:55 PM
ya it is a common size but those are real pricy lol and im deff not a high roller like most lol i have kids and wife so basic oem pistons will have to work till i hit the lotto lol!
so starfire basically just balance and blue print the motor is what ur sayin?
Starrfire
01-19-2010, 01:36 PM
yep, the forged pistons like they are talking about won't fit on a stock rod anyways. Not without re bushing them and even then I don't know if they can because I don't own a machine shop. I just know that the Rs machine pistons are okay, just get the hole bored to them because they run a little big. The 81.5 mm piston I got was 81.5mm, not meant for an 81.5mm hole like most would do.

BABY J
02-18-2010, 10:01 AM
Stick w/ the 81.5mm bore if your cylinder walls look good. ALSO - have your builder weigh the rotating assembly (loaded) - it will need to be ULTRA balanced considering you have a reworked crank and intend on 1) high rpms and 2) daily driving. If that crank isn't spot on you will know b/c the mains will go to shit and possibly the oil pump gear - but I suspect Brian/Doug at BC know what they are doing. It'd be almost disrespectful to get one of their cranks turned right outta the box just to check - depends on how anal you are.
The next thing you need to consider is the head - so far it sounds like the weak link to your setup. These are the 2 affordable guys that I trust - tell either one that Baby J told you to give them a call:
http://team4piston.com/ (ask for Luke - he is the MFactory All-Motor Insight driver, and his brother is Josh - they do good work - they start w/ a CNC port (they have good CNC programs) and finish it with hand work - flow bench numbers are shipped with your head.
www.stewartengines.com - Jim needs no introduction. Here are his head programs : http://stewartengines.com/headwork.html
Jim will hook you up w/ a hand-port and he is the REAL DEAL. Flow bench numbers are shipped with your head as well.
-- If time is not on your side - then go w/ Luke - they are fairly quick. If you have more time - go w/ Jim. He is "slow" but he's a perfectionist - it will be RIGHT before he sends it back. He's an artist - artists don't like to be rushed - LOL. G/L

Steer clear of the ITBs for a daily is my opinion - but Luke @ Team4 Piston runs them on their Insight and can offer some additional info.

this is a email i recived from crower today just wanted ppls insight, below is my email to him also
I apologize for the delay as I have been out in the shop. We make the
pistons custom for each kit so we can do any bore and compression ratio you
choose. The 12.3:1 is a little high for pump gas. I always recommend 11.5:1
but customers do run the 12.0:1 on 93 octane. No reliability issues as the
kit is fine for the daily driven vehicle. Everything is in stock except the
pistons -14-21 day lead time on those. Give me a call @ ext 101 if you have
any questions or wish to proceed. Thank you for your interest in BC
products.
Thank you,
Dustin Spencer

Subject: Stroker question
Hi i know that u must get these questions all the time, i have a b18a with a
p75 obd2 head that has be ported polished 3angle valve job, has a skunk 2
intake manifold w 68mm tb, password jdm power chamber intake with velosity
stack, the valve train consists of 62404 stage 3 crower cams with ur valves,
springs, and retainers, with buddy club adjustible cam gears, im running rc
440 injectors with str fuel rail and fpr, i have stock distrubiter with
accel internal coil with nology hot wires and pulse star plugs. The head and
all parts are brand new. Now my question is if i was to buy the crower
stroker kit thats a 92mm stroke and bored cyl to 81.5mm i want a comp ratio
of 12.3:1 is that attainable or is that to low for this kit?i dont want to
run race fuel I have a block guard with a obx oil pan thats 5.5qts, my other
question is can this app be daily driven or is it to much on the motors
bottom end to daily it? I want a powerful street car and built stroker 350's
all my life and dailyd them and would like to do this with my new passion.
Any and all info would be great.
Ps i have a ctr crank pully, 12lb flywheel, stg2 clutch, and integra type r
oil pump

03-02-2010, 03:44 PM
yeah he is right anything in the 12:1 ratio will need race gas...
cprtyler
03-02-2010, 04:52 PM
ok im confused now does it need race gas due to the larger stroke because i hear of guys running 12.5:1 on stock stroke using 93 octane with tune? dont get me wrong im not using this kit now just going to use my pct pistons but wanted to know ppls input for a futur build
BABY J
03-02-2010, 07:24 PM
12.5:1 is about the limits of pump on 93 octane. But that is all relative to other things like timing ... you can run higher if you want - but you'd have to pull so much timing that it'd be useless. If this car will see DD duties then keep it around 12.0 or less. Also remember cold starts on high compression can be a bitch --- you only need 1 good explosion to get the engine going but finding it can be tough. Also your ignition system has to be up to the task of punching through the compression as well
Don't confuse yourself by trying too hard sir. :)

440cc injectors will be over kill. ITR's put down what, 185whp stock? Why would you need injectors bigger than that? Also, you should've ordered an OEM coil.
Starrfire
03-28-2010, 01:34 PM
Yeah the coil is a bad idea, they are not gonna help. Actually it would probably do nothing at all. Honda ignition systems are very hot anyways.
The injectors are a waste of money, you aren't going to make over 190 wheel so you spent money just to say you had injectors on it.
Plus I don't think the 13.1:1 cr will be very becoming for a wheezing engine. P30 would have been the way to go. You are effectively making the engine less efficient by splitting the combustion in half with ctr's. The way to do it would be just flat top 10:1 pistons with a modified combustion chamber. So basically you should have bought some different pistons b/c you won't make a marginal increase in power from them, just problems.
