Okay, this is another B20 question. I have a B20B4 block which is the lower compression model form the factory. I have also picked up a set of Weisco pistons (84mm) and some Eagle 3/8" Rods. I was going to have my B18B sleeved and install the parts into it, but my budget has taken a major hit recently. I guess my question is, would it be worth my time to build the B20 block with those parts and boost it? I want to make enough power to get a 95 EX coupe into the 12's. Can it be done reliably with that setup? I will also be using a ported B16 head for the build. My turbo setup on my EG hatch that I am trying to sell ran a 12.88 before the stock pistons broke/melted. That was a 2.1 60' and the car weighing 2275lbs. with me in it.

I don't need anyone to tell me to do a serch or flame on me and call me a noob either, so save it for some one who really is a noob.

So you also have a b18 block?


If so put your pistons and rods in the b18. You can make enough power out of a b18 to get into the 12's without sleeving it.

B20's on the other hand is a crap shoot if you dont sleeve it.

civexturbo

Yeah, but I can't afford to get my B18 sleeved right now. The pistons I got are 84mm, which is the size for the B20 bore. I would have to get new pistons for the B18 to use it.

oh sorry i didnt catch that

so a b20 block is ok if it is sleeved, because i am going to run a similar set up. Forged pistons, Forged rods and boosted at about 20lbs

also, is a non vtec block worth building??? I have heard that if you are running forced induction that vtec is almost usless, can anyone help me on this!!!

B20's rock.

Im currently running 15psi daily driven, T3/T4 57trim 63ar. CRX with a B20 on stock internals tuned by myself. My best so far in the 1/4 mile is 13.1@113mph with a bad 60ft and a horrid 330 on street tires @ 14psi and spinning em hard... If tuned correctly, the motor can handle the boost, just like any other Honda motor.... PM me for more info.

!!!FISHER!!!

b20's have to be one of the funnest motors ive had in some time.... civexturbo you know how it goes on a stock b20 block that you can get into the 12's without any real crazy set-up.... and blaze45 i think 15psi is a little much for a stock block dont you think, and you should be pulling better times then that, maybe get some slicks...... i had a stock b20b 8.8compression on 8psi with slicks in my eg and i ran a 12.8 all day long

Group Tenacity

I went 12.01 all day with a bone stock b20b at 14psi on 22" slicks 4 years ago... The motor is still running strong in my commuter car getting 100 miles a day of commuting... its all in tuning...
for the original poster, if you can afford to sleve the block then do it, as everyone knows the b20 sleves are pretty thin, so eliminating that weekenss in the motor would be a big plus...

Not tryin to make excuses, but I was on street tires and if you read my post closly you'll notice that I had bad 60fts and 330s cause I dont have any traction. I also am a very inexprienced driver and have only made about 9 passes since I've turned the boost up from 7lbs. I have some 24.5x8x13in slicks this year so hopefully Ill be able to pull a low 12 second run, if not an 11 second pass if the clutch holds out. Too much boost on the motor? Impossible! lol as long as you have it tuned for what your running, it'll hold. I was thinkin about turning it up even more but Im running pretty high injector duty cycle as it is, so Im just gonna leave it alone.

B20's are garbage, anybody who tells you different is an idiot. Sell your 84mm pistons and buy some 81mm pistons for your B18 block.

Blaze45

lol I was wondering how long it would be before you'd be along.

beerbongskickass

Well you stupid tards just don't seem to understand...

Blaze45

Everyone whos posted in this thread hasnt had a problem and their setups they seem to running fine. If mine blows you'll be the first to know!

beerbongskickass

I don't care about your gay setup or if you have had problems or not. This guy wanted to know what he should do with his engine build, I let him know the truth. It's not worth it to waste time on a shitty b20 block and he should go with the b18. The all mighty BBKA has spoke... end of thread.

Saying your boosting your b20 daily on stock block with no problems is like saying your ******* a prostitute with herpes but you dont have any blisters yet.

Its just a matter of time. Good tuning is like a cereal box condom. Its just going to delay the inevitable.

dunt waste your money waiting for the b20 stock sleeves to let go, focus on the b18. you will boost the b20 over sum pistons you bought oversized?? sell the pistons and boost the b18. you will have a piece of mind that the extra 3mm thickness of the b18 stock sleeves will benefit you more towards liability.

blown b20 -VERSUS- selling 84mm pistons for 81mm pistons

think about it...

Well I tired to keep the thread somewhat friendly instead of imature name calling and poking fun of other peoples setup but I guess were all still in highschool. JDM turbo DC dont post useless and wrong information. The B20 sleeves are actually thicker then the B18s. Jeff @ HMT measured them himself and verified it. The reason why the sleeves are a weaker point on this motor is because of the single cast monolythic design that Honda used to get the 2000ccs of engine. I tried to keep thread somewhat friendly, but everyone seems out to bash on the B20s, just cause a few have cracked sleeves.

What positive technical contribution did you have to this thread? Everyone thought that the H22s couldnt handle much power on the stock block, but the last time I saw One-fabs H22 it was well over 500whp on stock internals. Guess that doesnt have anything to do with tuning.

Each person is entitled to thier own opinion, all I ask is we keep the thread on topic with relevant information to the original posters question. Im not trying to step on anyones toes here, but it seems like Ive done a pretty good job already, and for that Im sorry to anyone I've offended. Beerbong, I guess we'll just have to agree to disagree.

Blaze45 I don't get it. You seem to know exactly why I keep saying the B20 sleeves are worthless (shitty sleeve design), you even said it yourself, but you still act like B20's are worth boosting? That makes absolutely no sense at all!

Each person is entitled to their own opinion... Your opinion just happens to be wrong.

Well I guess I really dont get it myself. I had the motor, swaped it in, planned on boosting it, boosted it, and for some strange reason it hasnt blown up yet. I guess Im just sharing with others my good fortune Ive had with the motor. Others havent been as lucky while others have... I dunno.... What I do know is that Im beat. Its been a long day and tommorow isnt looking much better, Im off to bed.

dang that's tuff

shoryuuu

i dont c y people hate on the b20. i know like 3 people with that swap, boosted it, and have no problems.

!!!FISHER!!!

hey beerbongskickass you need to respect what blaze is doing here, hes askinf for advice and not someones ******* comments, im guessning youve had some luck with b18's, then that fine for you.... ive owned three b20's and ive put them through hell and back and ive sold every car that i had them in and they still ran the same as stock.....so just take a deep breathe and kick back another brew and relax
