I'm in the process of rebuilding my engine, its taking forever since I have to work and do it on my time off but I'm finally half way there.

I got everything out now I'm a little stuck. do you think a boosted B16A at around 250hp will be oke as a daily driver on a re-sleeved (with stock sleeve) block? or would it be too much I've read a lot of people running a lot higher on stock and that's it depends on how good the tune is but, as its my daily I'm not sure to go forged or stock pistons.

For Forged pistons and rods would CP Pistons Eagle Rods be good? and they says it fits all the B16 series engine except B16B but it says 99-00 B16 now im pretty sure mine is older a lot older, would these still fit?

 

Stock at 250 is fine.

 

Would there be a problem if I put rods with the length of 134.3 instead of 134.0? would this cause the piston to hit the valves?

 

I always believed they were the same rod but were too lazy to say .3. Anyhow, .3mm is only like .012" and there is at least .020 in an undecked block so no piston to head contact there. Your motor builder is really the guy to ask, might get misleading info like mine.

 

Got a set of 81.5 srp forged pistons for sale cheap

 

why re-sleeve with stock sleeves?

If the current sleeves aren't damaged then doing this serves no purpose... If they are damaged and cannot be fixed with an overbore then your best financial move would be to buy another stock bare b16 block

 

For your power goals, there is no need to even install ARP head studs...that block (provided its in good shape) will easily handle250whp in stock form

 

Could do nippon cast pistons. You can order them machined for use on stock or after market rods. They are similar to stock pistons but have thicker ring lands. To me its a good in between choice stronger then oem but less expensive then forged.

 

^^ Interesting, but too much work for something the stock engine can do with no additional benefits. I never understood switching out one cast piston for another in a turbocharger application.. what, for "lowering compression?".. Unnecessary.

Stay stock, tune well, drive on.

 

Think is how I look at it.

Every honda piston is made with the same cast material, correct? There is a thread out there called "highest horsepower on a stock block" There are ls/vtec setups, gsr, and b16 setups pushing 600+whp, all with cast pistons. Call me ignorant, but if these setups can handle this kind of power (who knows how long, and every setup is different), why can't mine? I personally, will not push over 500whp with my coated NPR pistons (made with a different cast which absorbs heat better than honda's cast)

But in the end, if he is only pushing 250whp, keep it stock... the block can handle 300whp+ easy, if anything, do arp rod bolts and arp head studs.

 

But see, you answered this question yourself immediately.(highlighted). You aren't them.. and they aren't you.. so why take the risk? What... just to prove something to someone else you don't know? I don't know how often you plan to tear this engine apart to save a "couple of bucks", but it makes no sense to tear it apart just to put in another set of cast (regardless of type/company or whatever your definition of "heat absorption is..*shrug* ) if the plan is to make better power at a later time. You do it once, and correctly with a planned setup, you'll never have to ask that kind of a question again.

As for using Headstuds and rod bolts for this power level... again.. completely unnecessary as long as the engine is in good mechanical health, and hasn't been separated. Save that money for better tune and continued mechanical health.

 

Best response in whole thread. Thread over.

 

A couple thousand bucks

 

^what the **** are you even talking about?

 

ah i guess its like the vitara phenomenon, offers a more than stock but VERY budget minded.

ive often thought about giving those nippons a try on stock ls rods/arp replacement studs. while it may not really allow me to run more power, it might be more forgiving at the same power level...just throwing ideas out there

 

The Vitara solution, well, it was what it was, and its going away, now that the notion of lower compression being "better" is out of the window.

I guess I don't understand How it can be "more forgiving", especially for the effort brought to tearing it down..

Seriously. I don't understand...
