Default WCHC why is the B16 the flavor of the week???

Hey guys, I have been following the threads here and on NASA forums about the current builds and rule changes that have taken place over the last few months. And I'm suprised to see on the B16 in so many builds. Is it because the build costs are a little lower? The torque of a B18 or K20a3 isnt worth the 100-150 LB penelty? I have no dog in this fight I was just starting to think about either building my LS or doing a swap for TT here on the east coast and have been very impressed with the build I've seen and just figured I'd ask why the B16 was chosen.

Thanx for taking the time.

I think people like the light weight of it, and also people have been getting some impressive power numbers out of it. (the B16a)

If the power numbers are really as good as it seems, i would think that the B16a might get hit with some weight.

But really im not sure that it is the flavor of the week around here.

SoCal (that i know of)
Benny has a b16b (the CTR motor)
Rennan has a B16a
Jeremy (or the orange EK he owns) has a B18c5
Jeremy's EG coupe had/has a B18b


in NorCal
Liam has a B16a
Brian Z has a B18c1
Bob G. has a K20a3
jimmy C has a k20a3
Austin has a B18b
Vito has a B18b
Mike L. has a H23a
Mike U. has a H22a
Chris S. has a B18c5
Dave W. has a B18c5
Dan W. Has a B18b

I know... I've followed your build as well over the last 2 years. I just posted the WCHC because of the attention the other thread was getting.

ZUL8R what is your set up? i have a stock B16 right now and i have a extra one laying around and i was just wandering what a good set up is because im a little confused if i should keep the P30 slugs in it or drop some PCT's for the bottom end?

i ran a b16 last season and if i hadn't broken a retainer it would still be in there. i also couldn't get down to weight w/o going crazy (i like my blower motor in the rain) so this season i'm going to try something different.

That's interesting that you couldn't get an EF to 2250...... There race weight in ITA is 2275......

Something has got to be off.....

I don't think the PCT/CTR pistons are legal for Honda Challenge in a B16A because of the need to modify the small end of the rod to use them, better to keep the P30's.

They aren't legal in H2 unless you're using a B16B block. Each respective block must use the OEM piston for that block, or the stock 0.25MM overbore, if another piston is used it must...here's the exact rule:

7.1.C(H1-H5 General Rules)
Factory replacement pistons or the exact equivalent shall be used. Exact equivalent shall be defined as the same dome/dish/valve relief configuration, weight, ring thickness and location, and pin location as the OEM replacement piston. Wrist pins and method of retention must also conform to OEM specifications. In the event that a .040 factory replacement piston/wrist pin is not available, the oversize pistons/wrist pins shall not weigh any less than the largest size OEM piston for that engine.


And here is the H2 specific Piston Rule:

10.3.B(H2 Specific Rule)
“Aftermarket OEM” replacement pistons and rings are allowed but must be identical in every manner to the OEM Honda/Acura part. Note: Piston size must not exceed OEM sizes.

This is correct!
To many people are making the mistake of not reading the entire H2 rule set!
H2 is NOT H1!!!

You can't mix and match parts. If you build a B16a, it must have all B16a internals except for the cams and valve springs/retainers.
If you build a D16z6, you must use all D16z6 internals and not A6 pistons with a Y8 head.
That type of thing is meant for H1 only...
