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")?

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...

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

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. ;)

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.

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.

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