In a quest for more power while breathing though a stock ITR muffler (getting pulled over with the Mugen) and running California's lovely 91 octane ****, I built a new engine with slightly more displacement.
Specs on the motor:

1994 B18B sleeved by Dan Benson to 85mm.
Brian Crower 92mm crankshaft.
Cunningham LS rods.
Import Builders custom 85mm 2cc dome pistons with a 1.120 compression height to accomodate the longer stroke.
Honda bearings.
Blueprint Mfg. LSVTEC kit.
OG B16 head ported and massaged by Tom Fujita aka Portflow.
(Another awesome job Tom!)
Portflow valve springs and retainers.
Stock ITR intake valves/Rev stock size exhaust valves.
Skunk2 Pro 2 cams.
GE cam gears-intake at +6, exhaust at +5.5 (indicated) .
Import Builders ported ITR intake manifold.
RPM 70mm throttle body.
AEM ITR CAI.
RC 440cc injectors.
SMSP B19 header.
Mugen mid pipe (no cat).
Stock ITR muffler.
Tuned on Hondata S300.


There is more in this motor; this was a quick tune to get the A/F, ignition timing, and cam timing close. At 191 tq/275 HP this thing is one of the strongest B-series motors that we have seen running pump gas. It's actually better than most K motors as well. It is stupid on the street with the stock tires-first and second gears just want to spin. Time to switch to the AEM EMS so that we can use traction control

Way to go Todd!

x2!

 

Great numbers! Just for reference what does your average k20 engine with cams, bolt-ons and tune make on the dyno?

 

When I saw this thread, I knew I would not be disappointed.

I'm probably your #5 cheerleader.

 

a beast for sure. and choking pretty good on that muffler and pee water gas. i wish i could here it run.

A stock 06 RSX-S with Intake and KPro made ~ 155/213. The average K20 with I/H/E KPro cams makes 160-175 tq and 225-240 HP depending.
A fully built high compression K24 race motor made ~200 tq/ 305 whp.

 

Another great motor of yours.

 

very nice,

 

Im impressed

 

you're crazy Todd

congrats!

 

WOW! Congrats!
Sick #'s!
This is WHP/WTQ correct? because it says "flywheel" on the top of the dyno graphs.
Were the 440's even close to being maxed out?
What was your final static compression calculated to be? around 11.8 ish I presume?
That is truly amazing #'s for 91 octane

 

Dynapack reads hub HP. The 440's are not maxed out on pump gas, but getting close to 100% duty cycle when I tried race gas.

You build some sick motors man.

 

Very nice. Always look forward to reading your posts.

Who said 92mm cranks didn't work! mine is for sale if anyone is interested im me.

 

Wow.... Nice build... Drop that in a CRX and win some races..

Awsome build as usual..

 

wow very nice thats just insane

 

C.A.T.

 

is this car going to visit a 1/4 mile? i wanna c trap speeds for this car/engine, much more realistic than any dynograph could ever be

 

B series still has the power to hang with the new guy k great numbers there. I bet with some more tweaking and tuning you'll get even more power. Thats on 91 octane in cali to, pretty amazing

 

Dammmm

Amazing.
