Stroking the B16b


So what's better p73 Or p72 using a ls crank micro polished and rebalanced?

ls crank I have no idea.

I have experience with gsr crank, only 1lb/ft of torque (less) difference on the dyno compared to a jdm b18c one.. The good thing is that a gsr crank costs 100$ :nice:

I bought the Ls crank for 30 took it to my local shop they knife cut,reblanced and did a blue print on it, so what i im asking is what pistons are the best to run a p72 or a p73 just want comp to be ok cause later on im going to go boost?
 
The B16B is the same block height as the B18C, its just the rods and crank that are changed to give a shorter stroke and hence the 1600cc capacity. HTH

O I didn't know that.. So basicly a b16b with a stroked bottom end is actually a b18, just have the wrong engine code stamped on it really.. Yano what I mean..

Ok so I'm defo thinking about doing this as I have a gsr crank n rods, can I use these wiyh ctr pistins in a b16b?...I'm assuming a stroked b16 is a more powerfeul engone than a b18c ? Because of higher lift cams n higher bottom end compression ?...


Can I just open the sump n install the b18 parts or do I need to change anything for the timing? Or just plug in a b18 ecu ?
 
Actually does that mean that in a b16 that the pistons don't reach the top of the block if it has a shorter stroke ? Or in a b16 does it has long rods and shorter throw on the crank to shorten the stroke and b18 has short rods and a longer throw on the crank to allow the rods to have a longer stroke travel while having the same distance ?

Depends of how much boost you want, but the p72 pistons will give you a compression leven of 10.6, which is ok for boost.

If you're going to boost like crazy, you better get aftermarket ones, wiseco, etc, with low compression level. :nice:

Yes you can use the B16B pistons with that setup, but it'll boost the compression to a 12.1 to 12.5 level, you'll need a good tuner and a fully programable ecu to drive safe with pump gas :)

I have a apexi power fc which will stand up to the job I think..

I'm definitly stroking my b16... That's a lot of compression for a standard engine,
I'd say that's a 200bhp b16.. :).. Ha

But have I ever read that the b18 timing belt is bigger ? :/

The B16B uses the same timing belt a B18C, :D :naughty:
 
is there a difference in size of the cam gears then?

anybody have a thread here with a sucessful stroked b16b with dyno print out?

All b series cam gears have the same size. :nice:

I have successfully stroked my B16B.

stock b16b and ecu = 135 whp 99 lb/ft torque
stroked b16b hondata, hytech and mugen intake = 170 whp and 119lb/ft of torque.

Dyno located at 6000 ft above sea level, number might seem to low for USA / UK users.

good luck.
 
170 whp , sounds like a good difference, what was that at the flywheel?....
what pistons did u use?
 
im gonna go with pct pistons oem size ,itr crank and rods, lightened flywheel and bottom pulley with power steering removed... that should be around 12.5 compression

with a good map i should see over 200 at the fly.....

much better ecu than power fc.... how much of gains did you feel driving the car on the road ?

and if you were to do it all again would you do it differently?

sorry for all the questions but your being so helpfull

Imagine having like 30 whp+ is just like driving another car. Also 20 pound of torque more, i really felt the difference.

The only thing I would change is to get a better header, not a ebay replica one.
 
i have just noticed my piston to deck clearance is only 0.006 according to the compression calculater you gave me the link to... is this okay?

ive heard of a good few lads putting pct pistons into there b18c's for more compression with no issues at all......
