Went to the dyno today w/ my buddy's stock b20/vtec and made 453whp 300torque @ 19 psi. Setup are simple, Nippon stock low compression b20 cast pistons stock rods and bolts. Head is a b16 w/ dual springs and retainers and ITR cams. Fuel used were mixed of 110 unleaded w/ 93 octane pump gas. Here's the video we took today.

Took the car to the track tonight and see what she does in the 1320 and here's the video:

is that a new record or something lol that seems exceptionally high for a stock block, how high did he rev it? im stunned the sleeves held up to that much abuse.

 

not a record with race gas

 

8k and no, I don't think it's a new record at all just sharing the info.

 

good numbers.

 

Thanks, I've tuned this car on the street first but now it gets to the point where it's getting squarely on top of 4th gear pull so we decided to tune it on the dyno.

 

Most all the failures on stock b20 blocks I've seen are thrown rods. Stock rod bolts can't handle the rpm and extra power. Cracked sleeves are usually caused from excessive cylinder pressures. If you have no detonation and do not beat on the engine too hard it will last.

 

w/o block guard ???

 

Without block guard.

 

hey vic where was it done at....

 

What snail did he run? Im looking to run something similar. I have a stock itr head, but im planing to run forge internals in the block.

 

It was done at Reinhart Automotive in Orange park by my house. Dennis the shop owner is an awesome guy he even ordered pizza for us to eat when we took a beak lol. I'm taking my car there and some cars that I've tuned on the street to use his dyno.

 

Did you tune it

 

Nice numbers. I'm hoping for something similar on a low budget side build I've been working on.



*Facepalm* He said that.

 

Hahahahahaha my bad

 

It is an old discontinued Innovative 61mm ball bearing w/ shaft play lol. Your setup should do good numbers when it's tuned.

 

the rex moves i was in the car today,but damn its all over


nice tune vic

 

Thanks, when are you going to the track?

 

Its not a stock block if you have low compression nippon pistons...

The b-series "vitaras"... nice car man... seems like yall built it well... The pistons should hold over 500... I dont know bout the b20 sleeves tho

 

Took the car to the track tonight and got what the owner wanted, to run 10 second in the 1/4. Congrats to Lembo the car owner/driver, good job buddy and good driving. Video is on the top of the page.

 

How is the car running now

 

Running strong. I know most of us are thinking that how long will this motor last knowing it's a stock bottom end lol I guess time will tell.

 

my personal theory is that honda put thousands of man hours into the development of these engines i dont know how much i want to **** with it (even though i have a ls/vtec). these engine are put together so well

 

Nice numbers.

 

great #'s. That thing must be insane to drive on the streets.
