so iam going to be doing bottom end work here with in the months ....but i have a few questions i need answered before i can get going with it....so i was wondering if there is any way i can stay with a stock bore of 81mm cause i really dont wanna pay for the work for someone to oversize it to 81.25. Also will the pistons i plan on getting the ctr pistons be okay with my head? i have a b18c1 engine so yeah. Also if i do have to bore it out bigger will i have to do any work on the head because of the bigger pistons? Another question is will i also need to get new injectors or will i good tune solve that problem?

check the link tell if u think i should get this...everything looks good but the pistons are not a acutally honda brand so idk just check and tell me what u think i should do i need some help on this one

 

if the cylinder walls are still in good condition all they may need is a fresh hone to clean them up so you can stick with the stock bore size.

are you really set on ctr pistons? look into jdm p73's or p30's as alternatives .

 

why p73s or p30s?

 

wont i make more power with the ctrs? yeah ill just get it horned out then i didn't realize that thanks.....so did any of yall check out that link on that ctr piston seat? and if i should get it even tho its not honda made pistons?

 

http://cgi.ebay.com/ebaymotors...ZWDVW try this link sorry guys

 

i did want to get the p73s at one point but ppl where telling me to go with the ctr pistons cause ill make more power

 

what cams are you going with? that'll help with the compression ctr's make.

 

s2s2 or maybe stage 1 not sure yet...but headwork is not till later...i just wanna get my bottom end built up cause right now my engine has 162k its time for a rebuild so i might as well get some good parts in there

 

ctr pistons in a b18c1 will bring compression close to 13:1. you're going to need one hell of a tune to pull this off on a street car.

 

are you sure man i checked it out and it was like 11:4....**** i might just go with the itr pistons then

much more accurate than most online calculators. but these numbers should still only be used as general estimations.

 

so what pistons do you suggest i go with man?

i still wanna use this car for dd for 3 more years you know

 

p30's or jdm p73's. just play around with that calculator and find something you like.

 

so arnt the p30s ctr pistons?

 

ctr's are pct
p30 are jdm b16a

 

so will i have to get new injectors for this build and also what should i get it tuned with?

 

stock injectors are good up to ~190whp. possibly more with a bump in fuel pressure but you're just making things work harder.

find a tuner and see what they recommend for tuning

 

no the P30's and PR3's are both B16A

 

how much whp do you think i could make with p30s and with new rod bearings,main bearings,and thrust bears...and like new rod bolts. and tuned

just with that bottom end work how much whp do you think i will maybe make like 165 or so?

 

im not going to make a guess because it's pointless to do so

 

yeah i guess we will just have to see... do you think i would be save buying one of those kits that comes with all the bearings and stuff rings and washers....when the pistons are not honda made?
