i got a b16a2 engine block that i'm rebuilding for a nice daily..should i just go OEM b16a2 internals again or what would be a nice set up for a nice power n compression? thanks

 

Get P30 pistons if your looking at OEM parts. Locate some ITR/CTR cams, a good header, IM and exhaust, get it tuned and you should be happy. What kind of budget and power are you going for?

 

not too much as far as budget...sumtin simple..thanks

 

What's considered to be "nice power?"

 

Start off with CTR pistons/CAMS. AKA build your own B16B.

 

Thats impossible w/o a b16b or b18c block.... and CTR pistons SUCK as far as fuel burn is concerned.

 

if you understood how flame propagation works in the cylinder then you would understand that statement is false. dont get why people bash ctr pistons. me and plenty of other people have made a lot of power n/a with them

also all of the high compression n/a motors running on alcohol/methanol/ethanol/q16/c16 have pistons with rather large domes

to the OP
i would switch to PCT pistons in that b16 along with throwing in some ctr cams/springs/retainers
if the PCT piston was good enough for the b16b from honda its good enough for you

 

Alcohol/meth/ethanol all combust and burn easier then convention gasoline, which is also why MPG is terrible using them, or even a mix like todays gases. Ot allows the fuel to burn cleanee/hotter and more complete.
Im not trying to create an arguement, just my experience with the CTR pistons have never been top grade. MOST motors I have seen torn down running them the pistons were caked in unburned crap and such. In a B16 they do work pretty well as apposed to a 1.8, put I still like the P30's or a custom dome over them.

I know/you seem like your a reputable tuner so I dont second guess what you say. I know we had a headbutting clash about the supertech VS, but thats just an opinion thing. No hard feelings from me.

 

I don't know but my friend had PCTs .10 oversized(81.25) in his b16a/b16a2 head 97 h/b, crappy i/h/e with a CTR tranny and we through in my CTR cams and guess what, **** pulled pretty hard untuned. Imagine if it was dyno tuned with proper bolt-ons. Everything else was stock.

 

from what i hear there is notin really diff for them pistons his has now to p30s but i really dnt know

 

There is quite a defference in the PR3 and P30 pistons. PR3's have a small dome, flat of the top. P30's have a larger dome thats a bit more "peaked" The compression difference if he were to bore the motor and run them would get him in the 10.5:1-ish range. The PR3's will be at 10.2:1

 

The difference between the pr3 and p30 pistons is only.2 of a compression point. Visually there is very little difference between the two pistons. There is a large difference between the PCT (CTR) pistons and all the other honda pistons. They are the heaviest stock pistons and large domes aren't ideal for flame propagation. The only motor I would consider using them in is a b16 though.

 

so the questions is which would be better??...the OEM B16 pistons or the B16B for a nice daily...

 

since running supreme from the pump is required for pr3 or p30 pistons you might as well go to the PCT pistons and get more power out of the fuel.

pr3 pistons put you around 10.2:1 c/r
p30 pistons puts you around 10.4:1 c/r
PCT pistons put you around 11.9:1 c/r

going from pr3 to p30 pistons is useless...that whole 0.2 difference in compression will do nothing....going from 10.2-10.4:1 to 11.9:1 however will give you a bump in power. plus later on down the road if you decide to go to a bigger cam you will at least have the compression to run it. all i see is win win with the b16b pistons here.

 

B16B it is?

 

LS crank!

 

You are retarted. Never in a B16A block.

 

why not? Or at least a crank with a longer stroke

And don't call someone a retard when you can't spell it.

 

Call me out on a typo, cool.

A GSR or LS crank will never go in a B16A, EVER. The static CR of a B16 w/ a LS crank is sometthing like 35:1. You would need to have some sort of SHORT and I mean SHORT rods produced.

1.8 cranks go with B18's and the B16B
1.6 cranks go with B16A's.

This would be about like running a B16A crank in a LS or B20, about as useful as a poopy flavored lollypop

 

Well if your gonna say a ******** comment you can at least spell it right. You should just find a more tactfull way to correct people unless you have a habit of making fun of people with retardation.

I forgot the deck height is shorter on the b16a, I would still find a crank/rod setup with a longer stroke, or just go with a bigger block.

Or he could just go with what you said and get a miniscule diffrence in cr by switching his pistons, what do I know im just a retart right?

 

pct pistons - bumps compression to about 11.8:1
type r cams
type r valvetrain, or aftermarket upgrade
tune.
