i am thinking about building a b16 for my daily driver ek. right now, i have a 16a2 head from an 00 si and a jdm b16a block. I want to replace the pistons for some .25 ctr pistons and shotpeen the rods. Is this the best way to go? What suggestions do you guys have? thanks

 

I would do somthing like this

bottom end :
balance everything
ctr pistons
shotpeen rods
new bearings/seals

head :
port/polish
ITR intake manifold and TB
00 ITR cams and valvetrain
thin headgasket

lightweight flywheel , a nice 2.5" collector header and GOOD exhaust

tune it a bit with fuel and cam gears and it would be very fun and fast.

best of all OEM goodness......

 

Nice and reliable

 

wouldn't worry about the rods. Stock will handle a NA setup just fine.

 

Depends on the builder, always.

 

I learned that one the hard way.

 

for piece of mind shotpeening cost almost nothing.......

 

good suggestions!

TodaSi on th eboard here had a B16 with Toda Spec C's that made sick power, so you can always upgrade to bigger cams down the road after using Doc Cortez's suggestions

 

we'll find out next year.......

 

I'm rebuilding my B16 in an attempt for 200+ whp. So if that is your goal then here is a bit of insight.
according to JUN
You can bore to 82mm and install some 12.5:1 comp pistons
Install JUN III head
Install Hondata
Tune
200+ whp just like that...
Now, mind you, I'm one to go a little overboard so I want to bore and sleeve the block to something bigger if I can. I would definately shot peen the rods, after destroying the piston in my old block and the rods being perfect, I am an advocate of shot peening. Balance EVERYTHING you can.... it makes a difference. If you have the funds get a lighter flywheel, better throttle response is a happy time. It's all about what you want to get out of the car though. Don't take any advice too literally until you decide what you want out of the car. I'm just going for an all around runner... 1320, Solo II, Street... maybe a little drift as well... for me that's over 200 whp.

 

thats a BIG goal.

why stop at 82mm ?
sleeve it and bore it to 84mm , get a 1.8 that revs to the moon with that rod/stroke ratio.

no way.

you said drift and you own an FF , perhaps you should edit your goals to go with the car you have.

a 200 WHP B16 would be more than just a JUN head and 12.5 C/R......

 

I have a friend who built his B16A using almost all OEM honda parts and put down a little over 200whp with dyno tuning of course. The motor was setup for grip racing of course.

Complete stock type-R head w/intake manifold BUT used a B16A TB.
Spoon camshafts (if you didnt know, these are made by Honda for Spoon)
Adjustable camsprockets
OS CTR pistons
Thin heagasket
Mugen 4-1 header
Reprogrammed P28 ecu (using infamous mugen proggy)
Lotsa dyno time.
Made a tad over 200whp.

 

thats very impressive for a tiny B16 not highly modded.
do you have a dyno chart ?

and LOTS of dyno time probably isnt a strong enough word

 

dang, 200 whp on a 1.6L, thats about 125 hp per liter. I'm just building a daily so about 170-180 whp would've been good enough. on g-speed.com, I saw Omniman's b16 pushing 180whp with mostly oem parts-ctr pistons, itr cams & valvetrain. he made it seem almost easy. thanks for the input

 

yeah, b16's are fun the play with.

Dr. Cortez: sorry I don't have his dyno sheets.

 

 

...das OK.....

 

This is awesome. I plan on using a similar setup with my b16, only I'll probably use stock p30 pistons. I am very interested in learning how to make more power through blueprinting only, so the guy that built my lsvtec is going to show me how to blueprint. I'm still an amatuer, but I'm dying to get some real experince.

I'm hoping for around 180whp....BTW is it very easy to pull 120lb.-ft. of torque to the wheels with a b16?

 

I have to ask if he used the B16 TB on purpose or just hasent upgraded yet ??

 

curious myself

(nice numbers tho)

 

he didnt have an ITR TB at the time, but from what I remember I think he tried and ITR TB and it lost a little power. The B16 TB made a bit more power because of its venturi effect.

 

thats what I was getting at , I'll have to dyno both and find out

 

word..let us know how it goes.
