same here interested in peoples experiences and info

**JDMirza** · 06-30-2008, 03:18 PM

Yep, this is being everything on a stock b20(bottom end) and example using a b16 head on top -- other then changing stuff like the water pump, timing belt, studs, etc. the required stuff.

**Grimm Reeper** · 06-30-2008, 04:01 PM

B20V's are as reliable as you build it. I'm still working on mines just to make sure that I get everything right.

**Grimm Reeper** · 06-30-2008, 04:02 PM

Here's a link www.b20vtec.com check out the site, they inform you of everything.

**scttydb411** · 06-30-2008, 05:17 PM

i tuned a guy's b20vtec w/ jrsc then he changed it out for turbo. it was pretty reliable and was making appx 300whp.

**southside** · 06-30-2008, 05:48 PM

Just dont try to take it to 9grand from every light.

**all-mota** · 06-30-2008, 06:59 PM

as long as a stock bottom end b20 is not revved like a gsr they are fine. built they don't have any issues either they run fine and are reliable if you don't cheap out when you build them.

Damn man, you are a lot of help. Thanks a lot. Reps.

**JDMirza** · 06-30-2008, 08:06 PM

What kind of pistons do you guys recommend, and internals like valvetrain and any other oem or aftermarket performance parts ?

**Vteckidd** · 06-30-2008, 08:30 PM

A stock B20 is just as weak as an LS motor since they use the same internals (rods, crank).

A stock b20 block you treat just as you would a stock ls block, keep the RPM or Revs down. Keep it under 8000rpm an it should last as long as you maintain it.

Built, the b20 is great for NA because you get a 2.0l.

Turbo id stay away from the B20, ive seen 2 or three crack a sleeve under moderate boost. The b20 sleeves are known for being thinner an weaker than the LS/GSR/B16 sleeves.

Is it reliable? depends on how you drive it. If you are going to do a stock b20 block, VTEC head, then like i said keep the RPM down. If you rev over 8000 it will not last long.

a set of rs machine cast type r style pistons some eagle or other good rods and the factory crank with be fine. throw a vtec head and some good size cams and valve train in it and you should make around 200whp. thats enough for most people and can still be driven daily to keep it reliable.

**Got Milk?** · 07-01-2008, 12:27 AM

GL on the build Mirza.

**JDMirza** · 07-06-2008, 05:19 PM

Thanks.

**DecoyOctopus** · 07-21-2008, 02:56 PM

thats why i said rub cheeta blood on it, and pick up your ****ing fone

**j0nbunklah0m** · 07-21-2008, 06:02 PM

my freind has a b20v and boy that **** pulls. and so far no problems with it.. gl

**mitch lab** · 07-22-2008, 08:12 AM

depends on how you build it.

**tippatone** · 07-22-2008, 09:40 AM

I just got some Toda cams, valve springs and retainers for a B16B i brought to do the B20/Vtec conversion. It will be a while before i put it all together, i plan to build this motor right the first time

**IndianStig** · 07-22-2008, 11:53 AM

yah.....it wishes it were an h22 but in the end it just fails.

**Tech5** · 07-22-2008, 01:23 PM

agree

Whoa now, no need to lie to yourself about the k killer stuff, definitely not the case, but fun none the less. I had a b20vtec w/ GS-R head and a b20b all stock for 60k miles, and believe me, I had fun with it, no problems, but now I have a k20 and wouldn't want to go back.

**Thighs** · 07-23-2008, 06:23 PM

just man up and swap in a SBC.

w3rd. K20 is the ****, its a new generation. I drove a B20vtec, wasn't impressed with the redline. It was also an LS tranny so I was twice as bored.

**JDMirza** · 07-23-2008, 09:09 PM

Alright thanks for letting me know.

**JDMJAYDC2** · 08-11-2008, 08:08 PM

i beg to differ on the k killer it all depends on the build i know of a guy right now with a b20 vtec that kills and i mean kills k swapped cars but he ****s money so im sure that b20vtec has the best of the best

That was the problem. Plus, I'm assuming it was in a DC. That didn't help much either.

I think this was the problem once

**G.C** · 08-11-2008, 11:54 PM

my heavy prelude with stock jdm h22a was even with the b20vtec civic from a dig. We were Neck to Neck. I dont know how to drive well yet so i spin a lot.still learning. I'm pretty sure if its from a roll i will get him. Not saying i will but we'll see bout it soon.

Must have been a sorry driver in both cars,and b20vtec must not have been built ****ty.

**Captain-Obvious™** · 08-12-2008, 11:27 AM

my buddy used to have a fully built b20 vtec w/b16 tranny with high compression pistons and all that...and a real good tune and that car dusted all challengers...

**Decepticon™** · 08-12-2008, 01:42 PM

CR-Vtec FTW

**turbob20** · 08-21-2008, 06:44 AM

mostly when a b20 fails its a b20z or higher compression motor then puttin a vtec head ontop of that makes cylinder pressure even higher b4 u start to boost. i personally have run a b20b 8:8:1 with a gsr head on 8-10 psi for over 4 years and was tunned by scotty at mainstream and makes 258-278whp on the dyno dependin on the psi bump and i always stay under 8000. shift at 7500.all i have done diffrent is use arp rod bolts as the rodbolts are under greater stress as a bigger piston is being slung up in tha bore at that velocity. 81mm as compared to the b20 84mm piston. id say do a b20b low compression on 8 psi and keep her below 7500 with out the rod bolts..
