the b20b only makes 126hp is this becaue the ecu and intake manifold? if i put my ls intake manifold and used my ecu and injectors would i make the same power as my ls but with more torque? this is a serious question. becaue i cant seem to find any b20z's for sale and i hate buying an engine with less hp then the one i had before..

 

im pretty sure its because of the compression ratio on it. the manifold does account for the low hp. if u decide to throw all that stuff on, get it tuned, u might be able to pull some more power out. the b20's arent high hp cars by itself. u need to do alot of stuff to it. hope that helps.

 

let me inform you. the newer b20b's came with 146 or so hp and more torque. the older ones came with the 126 or whatever you were saying. and yes. the ls intake manifold will be more efficient on power. so you dont need a b20z to get more power. although they have higher c/r. just get a jdm b20b and you are good to go.

 

I have a full turbo kit for my ls all i need as a downpipe and a exhaust and $$ to tune. so i was thinking the b20b would be good becasue of the low compression. the jdm nd usdm b20b's have the same compression. also one more question. would it be safe to run my stock ls ecu and injectors with the b20b? i need to drive it for a few months before i can put the turbo on.

the bolded statement is a very BACKWARDS move...

 

well i am goign to go turbo in the near future. and i realized the lower compression would be better.

 

same thing here i have a b20 i'm doin all the internal valves spring pistons rods but i was wondering how much to boost with stock sleeves or should i just resleeve

what you should have realized is there is more to it than that and downgrading your motor just for lower compression is backwards...ive yet to see the type r owner sell his engine for a gsr motor or the gsr owner sell his gsr for an ls motor...compression is not a culprit...you got some more research to do, or if you researched, you didnt understand what you read

 

memphis is right. get good tuning and the compression shouldnt be an issue. hence, people turbo ls/vtec motors all the time. they just have good tuning and do all the work correctly. no half assing. b20 sleeves though are an issue. if you are going to turbo a cheap motor. might as well stick with a b18b.

 

oh. and yes. use the ls ecu and injectors. actually.. you HAVE to use the ls injectors.

 

to answere ur first question, the ecu and im hurt power drastically. before i went b20vtec in my DA and it was jus a stock b20, i would bull on stock ls's by like 5 cars. no doubt about it, b20 makes more power after switching im, ecu, and injectors. now moving on to the whole turbo idea, DONT DO IT ON A B20. keep ur ls and boost or get a b20 and plan on sleeving. but, if ur gonna sleeve a b20 its pointless might as well save ur money that u would spend on the b20 and jus sleeve ur ls. ls is much better for boost. ive seen some b20's crack sleeves on 220 whp. (its normally due to a bad tune though) therefore i can not stress how important a tune is. my car is completely out of tune right now cause im runnin a stock p30 on a b20vtec and i kick myself in the *** for not having it tuned yet. also, the issue with b20's is not how many psi it can hold, nor is it the compression the issue is the tuning and the amount of power ur gonna make. just dont exceed the power limits of stock sleeves and dont run a boosted b20 untuned. nuff said

 

i am not just getting a b20 just out of the blue, i cracked the ringlands on 2 pistons on my ls it had 160k miles. i just wanted to get a b20 because of the up in torque and the lower compression. and i am goign to get a super good tune this time. actualy im gettin a b20b put in tommarow. thanks for all your help.

i am not an idiot so dont talk to me like i am. what i realized is that i am just goign to get a b20b because the fact that it has lower compression then the b20z and also i cant seem to find one for sale anywere.

who spoke to you like an idiot???? you presented yourself as someone that had a half assed knowledge about his future turbo plans...had you taken the time out to understand the concept behind everything you would know its unnecessary to go for lower compression especially when youre talking about the stock compression of a b18b...the b20 has sleeve issues...not the prime choice for turbo...so not only are you downgrading on power but also reliability (ironic isnt it? the fact you thought youd be more reliable with lower CR)....nobody called you an idiot...you presented yourself as such...

 

i hate threads like this. people come in and ask us an opinion on something than completely disreguard what we tell them. if ur jus gonna go with ur own opinion than dont ask! but dont forget to come back in here in a couple months and holla at us about how ur sleeves cracked and you dont know why. i would recommend going all motor b20vtec ftw

 

yeah..i wouldn't recommend boosting a b20 unless you have reinforced sleeves. save your self some time and money do it the right way the first time.

 

just do what i did. i found a b20b for $565 and swapped it over. since its an OBDI motor you will need to swap out the oil pumps because it doesnt have the crank sensor. besides that the intakem mani with injectors t/b and fuel rail form the b18b will need to be used. again OBDI to OBDII the b20b JDM motor doesnt have all the sensor hook ups. once you have finished this swap you now have a spare b18b to build. remember to get new IM gaskets and all your fuilds and filters and probably a front main seal when you tak off the oil pump. it took me friday afternoon at about 12:30 to 9:30 then saturday form 11:30-9:30 then sunday an hour to get her done. i am a weekend mechanic with limited tools too. the motor feels great. i really didnt have an acurate comparison though because the b18 was shot when i bought the car. i know i am in need of a tune now though so the next thing i am buying is hondata.....

that was my main question nd that has been answered. so this thread is over. thanks

 

well the difference in power is not from the IM and injectors at all. the difference in power is from the lower compression the b20b has. even though its a larger displacement than the b18 the b20 doesnt make power in the same area either. the bore and stoke are different and so is the compression not to mention the different cam profile and they share the same head, so the b20b is bottlenecked because of head flow. that is the reason for the difference in power. i made my statement because if you planned to stay OBDII then you will HAVE to swap the IM and ect. regardless if it makes more power or not. so the answer to your question is NO it wont make the same power but will make more trq than the ls motor.
youve got an attitude man. you need to chill. you ask for help and then try to act like you know it all when your obviously not understanding/listening to what you being told. NOW THIS THREAD IS OVER!!! LOL

stroke is identical. and the ls cams are slightly more agressive. thats only about 2 hp difference. the powerloss is mainly due to the im and ecu.

actually. the b20b makes more hp than an ls motor. and torque. and the b20 head flows just the same as an ls head. the b20b is superior in my mind to the b18b besides the thin sleeves. lets not even get into the pr8 head.

serious. i was in search for one..but never could get a hold of one. what was the deal neways? why did honda decide on that head design for such a small batch of motors?

cause in the nonvtec search for power the honda gods blessed a few souls that drove Mom SUV's...assuming itd never be discovered by us

haha...eh..now i just needa find a way to please the new woman.

Goals: 1. Find out what was up with honda and the pr8 head
2. Please the woman.

oh..and find out why i sold my integra.
