Im looking to get sum new pistons and rings. Trying not to get too crazy with parts and cost. Was wondering if any bseries pistons will fit my b18b1 as long as the bore dia is 81mm. Or does it have to be the non vtech ls pistons? Does the gsr vtech b18c1 pistons fit the b18b1? B18c5? Or what pistons from what series xan i use to give me a lil higher compression rating for all motor? My goal is to make an all motor, just a lil qwick street racer, nothing pushing 500 hp or more? Im just looking to upgrade injectors, fuel rail, throttle body, pretty much just easy minor bolt on parts. I figure im changin out valve stem seals, may as well start from scratch w a motor w 150000 miles. Sorry for the rant, not familiar w civics. Just got mine two weeks ago. Thanks for any help at all.

 

whatever you do, dont drop a "vtech"....

i mean no disrespect and my intention is not to discourage you but some of the guys on here wont go for the noob questions like that for obvious reasons so before they reply to you and you get upset or at the very least get discouraged by them.. dont.. dont let anyone discourage you.. your just going to have to hook up with someone who at least knows the basics and has been around the block a few times but not someone who thinks they know what their talking about that has no experience but someone who has years of hands on experience specifically with honda's and b series engines.. who can teach you the "ropes"


anyway, back to your questions, a set up i had back in the day...


b18b1 block
- 81.50mm CTR pistons/oem rings (sometimes blocks have to be bored out/honed to a bigger size hence the extra .50mm)
- ARP rod bolts (A must in my opinion.. probably the cheapest insurance in the world, adds strength for the higher rpms and higher power band)
- ITR oil pump

b18b1 head
- crower dual valve springs and retainers (comes altogether in a kit i believe)(HAVE to have them if you install more aggressive cams which you'll want to because thats what creates a lot of the power in a four cylinder is the flow of the head)
- crower stage 2 cams (basically bigger so obviously increases horse power due to the engine breathing better (adjustable cam gears are needed for the tuner)
- Blox Intake manifold with a bigger throttle body (you want to match the size of the inlet on the intake manifold to the size of the throttle body)

Just remember, do not run an engine like this on a stock ecu and think its okay in the mean time until you get the money to tune it, if you dont have the money to get it tuned then don't drive the car cus you will cause damage if not ruin the engine altogether... a set up like this should be broken in on a dyno as well as tuned on a dyno before you drive the car at all.. otherwise you'll run too lean because you added a bunch of air to the engine without adding fuel.. the tuner adds the proper amount of fuel obviously along with adjusting some other things too.... A MUST.. not up for debate or procrastination plus you want power right? nothing makes more power than the right tuner tuning the car... for whatever reason it usually takes people some time to believe that... ive seen people blow engine after engine because they didn't wanna tune the car... easily the dumbest thing anyone could do.

that set up was just an example and im half asleep anyway right now but i remember when i first started posting on here and didnt know much and was easily discouraged so i thought i would bull **** with you at least if nothing else and maybe you'll learn something...

now the set up i listed is from a long time ago and i dont remember much in general lol so im probably not going to remember much from my old "nonvtec" all motor set up

so for whatever that stuff is worth, hopefully maybe gave you some food for thought if nothing else

 

Thanx after, im just trying to find out facts, i can ignore bs now, should u tune it everytime u add something or just when u start adding major stuff like cams, valve springs, and major stuff like that? Cause as of now i just wanna add sum good pistons for my motor later when i do drop alot of parts into it. And how can i find a dyno tuner by my house or area? And could i just chip my ecu or does it have to actually be dyno tuned? Im really interested in learning all of this. Not just throwing stuff on and hey i got a civic. What hp were you running on your car at the time? Im looking to max mine at like 225-300 Nothing tooooo crazy. Thanx for the tips im deffintely gonna do this correctly.

 

tune your car for an intake or something very minor.. no. But swaping out pistons isnt as easy as just swaping out pistons.. you'll have to take the bottom end of the engine to a machine shop so they can properly hone if not bore and then hone the block and assemble it correctly with the new pistons/rings... but the thing is if your going to all that trouble then most people would recommend changing a lot of things.. gaskets/oil pump water pump etc and they are right.. the main thing is you have to know what you want in order to start to move in that direction.. from what your telling me it sounds like you need a lot more food for thought before you spend 1 more dollar.... i thought an aem cold air intake couldnt possibly be a waste of money but it turns out the intake was the least of my concern for making power and i quickly realized after doing some research that there was just about no point in getting a 200 dollar intake because in the end "you have to pay to play" theres no shorts cuts and no easy way to do anything and as much as you might be thinking.... well i just wanna do this and i just wanna do that real quick... the car world just doesnt work like that.... you'll hear people say.. "if your ganna do it, do it right or dont do it at all" and its 100% true so with that being said.. your weeeell short of research and the proper amount of knowledge to know what you want yet but thats fine and that's normal... like i said, it'll take time and research.. that is if you want any more than 5 or 10hp (excluded a shot of nitrous but even that has to be done right and not for beginners)

225-300 basically is impossible unless your civic has forced induction (turbo charger, supercharger etc)

guys spend thousands of dollars and months if not years of their life to get to 300hp in their civic so just keep that in mind....

i recommend surfing through honda-tech and checking out builds.. your most likely going to land on a lsvtec build given their simplicity... it was the first motor i wanted to build and here i am years later building another one...

if its a daily driven car i would keep it simple and step up your knowledge on lsvtec builds with oem parts, thats going to be your best bet and they are a lot of fun for an introduction build... forced induction is harder but again with more research and knowledge you may end up going that route who knows....

no matter what, i wouldnt spend one more cent without sitting in front of that computer for the next month at least and doing some research.. getting familiar with the "honda scene" and the b-series motor... once you feel more comfortable you'll know what you wanna do and you'll start to move in that direction

 

to answer your question about how much power i made... not enough and it was way too much work for a little more horse power, not worth the effort at all.. it was fun but i should of put more thought into it... i was anxious to do something, anything but i quickly found out why people tune their cars...

i didnt tune my new engine (the ctr pistons/crower cams etc) and i tore it down later and it looked awful!!! it ran extremely lean and was going to fail any day.. all because i didn't think i really needed to get it tuned right away blah blah blah same ol story so knowledge is power... except if your me then you just cant make up your mind lol jk

 

Lol i understand what ya getting at. I know what i want on my car for the goal, and yes it will take sum time for sure and im exploring honda tech a little more now that i know what im doing on here. Lol thanx for the advice. Imma start hunting for a dyno around my area so i can throw my stuff on all at once and drag it down there ad get it tuned. Names daniel by the way. Take it easy pimpin.

 

This thread makes me feel like the smartest member on this forum. Do some research kid, I'm sick of reading these dumb threads. It's been covered a million times.

 

Please don't use CTR pistons....Please.
