I dont want to go vtec.. so i was wondering what mods to do to make some power? I am considering Crower cams as the first mod, but what else will make some decent power on it?

in my experience bigger cams and high compression hit hard on the LS and B20, headwork helps a lot too, in addition to a good header. I've yet to try a good intake manifold on one though.

 

What cams and slugs would you recommend?

I am looking at the JDM ITR (2.5 Collector) for a header, and ITR for Intake manifold.

Plus i have a YS1 LSD to put the power down.... added bonus

 

goto CSi:Southwest and ask Val what he did.

 

I recommend Crower Cams and the Skunk 2 Manifold for the LS , as well as 4 into 1 DC JDM Type R replica header.

 

checked out "Val's" mods and stuff... pretty impressive stuff..

anyone else have any input?

 

i would go the nice untravled road of jun 2 intake and type r exhaust.

 

i hear that is a good combo with a vtec motor, but im going no vtec...

 

I would definately, without a doubt, get a crank case ventilation system, like the one Endyn offers. The MOST overlooked thing when doing a B20 build up, vtec or not.

 

what about CUsco catch can?...is it any good?

 

it's fine, but it won't work on the B20, as there are no openings in the back of the block for crank case ventilation. Remember, this motor was designed in no way shape or form for performance, just hauling kids. The Endyn kit comes with fittings that replace the access holes in the block to use as crank case ventilation.

 

can you clarify this for me please?

crankcase ventilation? ( i searched on endyn's site but i could not find what you are talking about)

I have a 99 JDM B20 in my car and it has the crankcase breather that goes from the valve cover to the intake.

 

if i were you, since you arent going v-tec, i would first work on freeing up all the airways. Stage 3 port and polished head work, JG manifold, headers, and straight pipe exhaust. Then i would work on valvetrain with titanium springs and retainers, valve job, high lift cams (i run the crower stage 3 cams, they are great). The i would run Arias 12:1 pistons with eagle rods......i have experience with all these parts, thats why i recommend them....thats what i would do, always remember if you dont have v-tec work on having the least restriction and rotating mass as possible....hope this helps

 

what is the idle like with the 62403's? is it pretty rough or is it just a bit lumpy?
Also, where do those cams make power to? and what kind of fueling are you using?

Thanks Mang

What you have is the valve cover breather. This is different from the crank case breather.

The crank case ventilation on most B series blocks is a black box. This box plugs into a vent which leads into the crank case. This box seperates the oil and keeps it in the motor, but does not remove the oil vapor from the air. That's what a catchcan does, and is used in addition to the valve cover breather. Without it, you get crank case pressure, which has to go somewhere, and that's usually right by the rings, then forcing oil up with it, combusting along with everything else, effectively lowering your octane, and increasing the chance of knock. This will also shorten the life of your rings, and cause your motor to burn a good amount of oil, even with perfect compression and leak down numbers.

 

I agree w/ John. The PCV system is an important aspect of a proper B20 build.

I have the Endyn catch can installed, and in the past 300 miles(breaking in the motor), I emptied the catch can once and I got about half a quart of oil from it.
BTW, I opted to plug the bottom as opposed to running a continuous loop, the way Endyn gives it to you.

My B20 setup will be dyno'd very soon.... it's in my 92 CX. I'll post results once I get the dyno runs in.

B20-VTEC Motor
*GSR head ported by Endyn
*Skunk2 manifold ported by Endyn
*CRV block w/ Eagle rods and Endyn pistons (12.3:1)
*JUN2 intake cam, ITR exhaust cam
*SMSP big tube B20 header w/ 2.5" catback
*Hondata Stage 4 w/ RC 310cc injectors

Should be nice.

If you're interested in B20's... I posted either earlier this week or sometime last week about my friend's motor. For what it was.. pretty stock.

B20 / 11.3:1 compression, stock ITR head and cams, DC JDM header, 310cc injectors and a Skunk ECU. 202.8 and 153.0 at the wheels. Definitely

 

Thanks for your responses.

On the topic of going with a vtec head, im not too keen.. I personally do not have the tools to properly do something like this myself, and i don't trust any of the shops around here to do it. Honestly the shops around here really suck ***. I figured by keeping the motor non-vtec, i would avoid a lot of the hassels encountered when doing a ls/vtec type of swap. I do want a reliable motor, and from experience with the locals, i dont even want to try it. There are too many people getting screwed around here, and i dont want to become a statistic.

 

There ya go...non-VTEC B20

11.4:1 Compression
Crower 62404s
Skunk2 intake manifold
CAI
JDM ITR header
Tanabe exhaust
no cat
Chipped LS ECU / S-AFC

 

But, I never burn oil...ever.

 

WOW.. i had no idea.. i mean i knew i needed to integrate the breather in there somewhere but i thought a cusco would be fine.. guess not.. haha.. good thing i dropped in here.. i have a B20/Vtec built from the ground up ..waiting to be put in..

B16 head mild p&p
+1/2 mm oversize stainless valves..
tit. springs&retainers
JE B20/B16 head 10.5 pistons
head milled to bring C/R up to 11.0
arp head studs and rod bolts
custom grind Crowers.. identical to JunIII w/ a bit longer duration for the longer stroke...
stock rods for now.. until i can find lighter ones than stock....(any ideas??)
Skunk2 manifold
310 Rc's
...... umm i think thats it.. GS-r tranny w/act 6-puck 11lb flywheel...V-AFC .. SOHC mugen prog in a 95 GS-R ecu.. so it wont look fer knock sensor.... going into my 1993delsol s ..haha.. delslo no mo! haha how hard is the installation fot the endyn breather kit as i will be buying one ASAP.. er at least as soon as i can get offa this fukin ship...out here 10 miles offa the coast of pakistan...bastard bin laden...ughh. suks.. may isnt coming soon enuff.. haha let me know about the hook up and if anyone has ideas on rods... tenks

 

This is exactly who i was going to recommend. Now if you want to go Vtec, let me know.

MikeK: Any chances you have pics of the IM ported by Endyn? I'm contemplating if I should have my B18A1 IM ported with stage 2 headwork or if I should look into a skunk2. Skunk2 = more power up top (shorter runners) and the opposite with the LS IM.
