Well, you appear unhappy over the fact that I gain personal enjoyment from alcohol and video games, which...makes about as much sense as **** on a mule, just sayin'.

I need help with charge piping diameter.

Those of you who had followed my build (98vtec, H2b prelude), know my setup but I'm having a hard time choosing between 2.5" or 3" hot and cold side charge piping.

H22
89x90 10.5:1
Crane Rollers .440" lift
S366 T4 .91 single scroll
30" runner turbo manifold

Basically, the goal is to reduce any amount of lag which is why I've designed the runners in the manifold as long as the are as well as why I'm considering 2.5" piping.

@850 what are the power goals?
I thought I remembered reading somewhere that a guy with an h22 switched his charge piping/ic setup from 2.5 to 3 and had a significant increase in power.

2.5" inch is fine bro, that is what I am currently running.

Agreed. you don't need 3" for your build.

2.5 is plenty. Period

FWD drift season is finally in my area!!! Oh yeah, going to be greasing up that handbrake lever for sure; gotta love winter beaters and/or track cars in an open field , never seems to get old.

Since we touched on secondary tensioners in 1158s thread it reminded of this picture.



This is a clockwise rotation B16 developed for the Atlantic series open wheel cars. It kind of flopped and this engine has been for sale for quite sometime. There aren't any photos of it with cam gears and a crank pulley installed so I'm trying to figure out exactly how this would work with appears to be a stock length timing belt.

Not really surprising that it isn't selling. Honda kids say they want unique, but it's more like "we all want the same unique". Give them something truly new and interesting, and they don't care. Something like that, though, let's be honest. It belongs in a museum.

Is it possible that the oem tensioner isnt used on that setup?

No oversquare b series builds :

I could be wrong, but isn't "oversquare" just a fancy way of saying more bore than stroke? The B16A2 has 81mm bore, and 77.4mm stroke, so uh...

I wish I could find one of my old timing belts. I would mockup that arrangement with cam gears and a crank gear and see what happens. Obviously with the engine being CW the stock water pump wouldn't work. I'm assuming the plan was to use a "blank" pump to use the water pump gear to space the belt apart from itself on the intake side. I would imagine being a legends car it used some form of electric or other mechanical water pump.

This engine was built to use carbs and had an output around 240hp. The major rework was the cylinder head. They machined new rocker arms and had cams made to support the CW rotation.

I know the shop that currently has the engine. I wonder if they would be willing to provide detail shots of that secondary roller/guide pulley. They just used the coolant jacket plug on the head. I can create a fairly accurate mental picture of the individual components that were used and how it was assembled. It would be fairly easy to estimate and recreate the design in solidworks

The main interest for me is using that layout to eliminate the water pump entirely. My engines will be using DC EWPs. My last build used the GE electric pump setup and it worked well but I don't think GE sells their pump blank separate. I know Meziere does though. Even though it's just a water pump gear on a ball bearing shaft with no rotor it has very little parasitic drag. Eliminating the blank would be ideal but probably not worth the time and effort.

I could say with certainty that the layout above would eliminate belt "whip" inherent with camshafts that have high lift and aggressive ramp rates. I really like the Endyn tensioner compared to the vibrant. It just seems to be a better engineered product. Although I'm biased because I've been a fan of Endyn for quite some time. I had a set of their Rollerwave pistons back in the day and they were amazing. I try and emulate their finishing techniques on all the Pistons I've used.

I plan I having them port my VTEC cylinder head for the 2l engine as well as using a set of their Rollerwave Pistons. You can't buy them anymore without a head package because the head has to be machined specifically to fit the piston design. They have a piston I think would be perfect that will let me run a slightly longer rod without changing stroke. Should be an all around improvement, especially with a slightly better rod ratio.

m4xwellmurd3r

Thats correct. Over square b series suck. Gutless wonders imo.

They have their place in displacement restricted classes but for a street car id prefer a bigger stroke.

A custom 84mm crank might be interesting though. According to the zeal calculator, an 84 crank, b18c rods, and some slightly taller (1-2mm taller compression height) pistons would get you back up to good compression numbers without poking the pistons out of the hole.

Never liked a B16. Drove a few stock SI's once. I think my LS could take em lol

m4xwellmurd3r

I know an ls could take them. Way more torque. Pair it with a short ratio trans and the ls even in stock form is a pretty quick setup (quick, just not fast)

ls joker

a stock b16 delsol kept up with me back in the day with my cammed da on stock ls tranny.

Picked up the band saw used for 65 bucks.

Vise for 35

And swag plate for 55

Got me a nice vertical band saw now

Oh, thank goodness you are back! Maybe you can help me decide which clutch to use or something? I was reviewing some datalogs, but for my no-fawks-given winter setup I think I will choose the cheap CC setup. Nomsayin?

(Naw, just joking, I didn't need your help at all, but I took this picture just for you, cuz NoBuildThread! )
