B20 turbo
 

I want to hear from people who have ACTUALLY done it, and their input. Not "I have a friend.." or "I know a guy...", unless you were involved in the actual building/tuning of it.

If you have turbo'd a B20:
1) What is/was your setup?
2) Did it blow up? If so, how much boost?
3) If it hasn't blown up, how long have you been running it?
4) What would you do differently if you did it again (and don't say "build a b18")?

Re: B20 turbo
 

B20's suck balls. Jeff Frank (Abaz the creator of this website) who I have been friends with for a few years had a B20 and his blew up. Our HMT tuner Dave Lee (Leed) has tuned a few B20's, he is a good tuner, and B20's have blown up on him before as well. The B20 sleeves are worthless and crack very easily even with good tuning. The mono sleeve design is a lot different than other honda sleeves. Get yourself anything else, B16, B18, whatever...

Here are some info on the sleeves...

Re: B20 turbo
 

While I appreciate your input, you didn't conform to my request.

Re: B20 turbo
 

What else do you want to know? I gave you all the info you need, if you were smart you wouldn't get a B20 (just trying to help you out man). If your going to be a sissy and run like 200-250whp you will probably be fine, but if you plan on pushing the block to 300-350whp or even building the motor with forged internals, you will be fucked. It sounds like you have made your mind up on getting a B20 already, so stop posting and go do it. You will be thinking of me when the sleeves crack. ;)

Re: B20 turbo
 

Although beerbong has a point about the integrity of the B20 motor, I have seen many do well with it. Ofcourse going to like 300+ HP is not recommended and it will probably blow before that but it is a good daily driver motor if you take care of it.

My friend has a b20 we got off of a JDM dealer and it has lasted plenty, it was initially NA, then sprayed with 75 shot of Zex :S, and now with boost. He has a log mani, 3" down pipe from CRP, external Dump tube, and a t3/t4 60 trim. The car was street tuned and halls ass with the b16 tranny. Like it is way faster then with the 75 shot, and that was running low 14's. Good Luck and boost f-what every one else says the torque is sick, and if you tune it well and don't go crazy it will be pretty fast.

Re: B20 turbo
 

sleeve it or you will blown this engine.

Re: B20 turbo
 

I have a b20 and probably driven it for around 6 months with turbo. It runs pretty good for a street tuned car and I am running on 5 lbs only. I went to the track recently and ran a 14.3@103mph with a 2.4 60 foot and a horrible alignment. I know b20s aren't the best for boosting but hell if it blows I can get an ls block for like $500.

Re: B20 turbo
 

8psi with a good tune/decent sized turbo = safe gaysauce b20.

Re: B20 turbo
 

Re: B20 turbo
 

My b20b has handled well! It started off all motor then 60 shot nitrous and now boost. Ran 14.0 with the 60 shot. Now with the t3t04e 57 trim 50 a/r comp. housing and .63 a/r turbine housing it has run as fast as 13.3 @ 7 psi. Running on the street for 5 months now. It's an excellent setup for street. No problems at all!!!! Just do it, You'll be happy you did!

Re: B20 turbo
 

13.3? 7psi? That's ------- ----- on a b-series...

Re: B20 turbo
 

On street tires. I don't think so!

Re: B20 turbo
 

Sorry man, it's -----. I have made like 5 passes with street tires on my car and ran 13.4, this is a stock D16 and full interior ex coupe. I was running 9-10psi, so on higher boost and more practice I'm sure I could have hit a 12.9.

Re: B20 turbo
 

We here at HMT only like people that boost a minimum of 10psi. B-series motor boosted = at least 300whp. ;)

Re: B20 turbo
 

ARRGH! BBKA STyle b20 = poop

Re: B20 turbo
 

Wow great info. I was contemplating on running a b20vtec with webers in an EF with like 282 duration cams. But know I don't think I will. So say a B18A/B bored 20 over wouldn't that compramise the strength of the sleeves too though? I really need to do more reading...

Re: B20 turbo
 

You can buy sleeved blocks for less than $1000 nowdays, just cruise H-T and you'll find the sponsors selling them. Atleast I remember some people selling them, however they are bare blocks.

You'd be doing good to get a B18 block sleeved with 84mm or 85mm sleeves, I can't remember which one yields the best results.

Re: B20 turbo
 

Ok, one last time - I appreciate and understand what you guys are saying, but it's not what I asked for. I didn't ask about running 300whp on a b20. I didn't ask if I should run a b18 or b20. And I sure as hell didn't ask you if you think less than 10psi is gay. I am trying to show you guys respect, so I didn't ask a question that has been asked and answered a million times (b1X vs b20). I asked a specifically targeted question. If I want 300+whp, I'd get an STi. I have a B20/vtec and was just kicking around the idea of boosting it for shits and giggles, and for the experience of boosting an engine. My next build will be a serious power endevor. This is just my daily driver.

The useful info I got from the thread so far is 220-230whp is ok, on about 6-7 psi. Any other experiences?

Re: B20 turbo
 

::) The ------- question has been answered, 8 psi good tune decent sized turbo. Nobody is going to give you there exact setup because nobody runs a b20 ---- pile. Sorry for not spelling it out completely for you.

Re: B20 turbo
 

And one last time, I answered your question already. If your going to be a sissy and keep it under 250whp (sounds like that is your plan) you will be fine. So build a homemade kit and boost your damn ---- already. Oh and post pictures and videos. Tune your damn ---- also.

Re: B20 turbo
 

No way man I love B20's. :-*

Re: B20 turbo
 

If no one runs a b20 turbo, then the thread should have no replies. If you don't have one, you should keep you damn mouth shut. Didn't your mother ever tell you not to speak unless spoken to? asshat.


I know you answered it already - but since you seem hellbent on runnint 25lbs of boost, I got the impression that you have not boosted one yourself - therefore, I was also not asking you your opinion. However, your opinion is much more pertenent and useful than the other douchebag. I have the tuning side covered (just got my ostrich in the mail). I'll be sure to take pics and do a write-up when it's done.

Re: B20 turbo
 

:-X :-X :-X

Re: B20 turbo
 

There is another pet peeve of mine. The fact that I have never boosted a B20 doesn't mean ----. The facts are still the same wether I have had one myself or not. I swear sometimes I want to get a B20, just so I can blow the fucker up and say I have had one.

Oh and I'm not hellbent on running 25psi. I just don't see the point of going through all the trouble boosting or swapping in a B20 and only running like 5-7psi and making a measley 220whp. If you want to do it for fun? Then that's great, it will be a good way to learn, but don't expect much from it. Shouldn't be that difficult since you already had the B20/Vtec in your car, so build a nice custom kit and your good to go.

Re: B20 turbo
 

My pet peeve.... newbs coming onhere, asking a question, getting the info they want (maybe not in the form they want) and getting all pissy over it!

Re: B20 turbo
 

I know way too many people that will talk ---- about this motor, that motor, tranny, turbo, etc. The only people I have learned to trust are those that have done it before. I believe what you are saying to be true, but I don't want to take the chance of the info turning out like a bad game of password. I appreciate that you chose to answer my question with good and useful info, rather than just telling me that its a stupid idea.

A pet peeve of mine - people that think they are hot ---- because they spend their life on a message board. Grow up.

Re: B20 turbo
 

I spend more hours in the shop building parts, manifolds, and motors then you do sleeping at night. I work a regular 44hr a week job and a good 30+hr shop week at night. And people on here will vouche for my work.

I personally don't have any experience with this motor, I just hate when people with a 4post count run their mouth off in the forums.
Sorry man, not to be rude or seem like I was bashing you, but but the only way to get what you want around here is to show a little respect and graditude for the answers you get.

Re: B20 turbo
 

When you come online and look for answers ------ by "word of mouth" thats something you just have to learn to deal with. If that's not something your willing to do, pick up a book and figure it out for yourself. ;)

Re: B20 turbo
 

That's why I always post good info when I talk about something. ;)

Re: B20 turbo
 

The only reason I have a low post count is because of all the good info that can be found here by searching. This is how you can tell I'm not a complete noob - I know how to use the search function.

Re: B20 turbo
 

WTF is that??

Re: B20 turbo
 

You don't remember the game password? It's where you have a row of people, and the first person whispers something to the next person, and it continues down to the last person, where he speaks aloud what he was told, and everyone laughs at how wrong he is.

I know this guy who ran 6psi on a sleeved d17 for 250hp -> a friend of a friend ran 10psi on on a sleeved d16 for 270hp -> this dude I met once ran 15psi on a sleeved d15 for 290hp -> I heard of a guy who ran a stock d15 on 25psi for 300hp.

Moral of the story, I don't trust anyone unless they have done it before. Would have a heart transplant done buy a doctor that has never even witnessed the procedure before?

Re: B20 turbo
 

you are one dumb ------- ------ sureshit331, you ask a question get good answers and get all pissy. I hope your ssac wastegate diaphram rips and you crack every ------- sleeve in that pile of ----. Remind me to "help" you as much as possable in the future ::)

Re: B20 turbo
 

exactly...but thats the same as whats going on here to some extent. these people have seen b20's blow up (if you were around a while ago you would remember abaz's) with moderate boost. The reason most of us dont have first hand experience is because we've seen how poorly they react to boost. But go conservative and youll be fine but wont make much power...hopefully you will get some first hand stuff from someone running a low boost b20vtec

Re: B20 turbo
 

remind me to never ask that question again

Re: B20 turbo
 

your a ------- faggot

Re: B20 turbo
 

they dont like cyl pressure. b20's always crack in the same spot, iits just they way they are made. theres nothing wrong with the motors, just dont go crazy, 10psi 250ish max hp... i wouldnt even go with one NA with more than 12:1 cr. if i was going to build a turbo motor id go with a b16 or b18b. for what its worth theres people making 240hp+ NA with these motors so honestly just build up the motor NA

Re: B20 turbo
 

That's called Telephone, nignog. Why would it be called password? That's a gay name.

If you must stay with the B20, sleeve it. :)

Re: B20 turbo
 

I didn't take the short bus to the special school, sorry.
