Does anyone know the maxium size I can bore a b16a to? I was planning on boring to 82mm, and I just wanted to know if that would be safe for a street motor. I just wanted some opinions on this, good and bad. Anyone running this set up? I have searched.

thanks

 

if i were you i would call golden eagle, i have talked to them many times about bores and strokes for blocks. they will custom make you any piston size you want

 

also want to know.

 

the reason why I ask is because I am thinking about the b16 stroker kit from eagle. Its seams to have a good r/s ratio from what I have looked at. I think it comes with 82 mm pistons and I am some what on a budget. I happened to get a bare b16a block for free.

 

is this going to be a all motor...motor

 

the max bore size recommended on a non-sleeved block is 82mm.
if you sleeve it, you can bore to 87mm(full racesetup) and 84mm for street is fine.

i highly suggest doing the sleeving over the stroker since its simpler. the eagle stroker kits are good, but for similar amount of money, you have a SLEEVED block already.

I know people are going to argue about R/S ratio and all, but honestly, how important is it really. we turn street lsvtec motors up to 9500rpm and pushing 220 hp to the wheels. no problems and still reliable. r/S ratio is a good thing to follow in theory. but not necesarry to make good power and to make a great motor.

 

the only reason for the stroker kit is because the block that I have is bare, ,no pistons, crank, rods. I would have to buy all that and the sleeves (I'm a cheep ***). But i will ask what is the going rate for a sleeved block from exospeed?

 

sleving service is $880 and includes the bore to size you want, hone, hot tank, deck,

 

thanks. I will have to think about it.

Okay you ready for option #3?
-Buy an LS crank and rods... cheap.
-Order custom pistons that have the pin hole made smaller and also moved so that you can use the LS crank AND the LS rods in your B16 block that is shorter-than-a-B18-block. I lost the thread but there are guys offering these pistons for about $650 a set. You may also need a bushing installed on the rod ends for the smaller pin.
-This setup gives you LS displacement and retains your B16 block. done. "poor mans stroker" I guess if you compare it to full setup from Crower, Eagle, etc.
-This would also work with GSR or ITR crank and rods instead of LS crank and rods, but be sure to be clear to your piston mfg'er on what you are running!

cool huh? not like you have more $$ but iff you did, you could combine the poor mans stroker with a sleeved block and run 84mm pistons for a 1.9+ liter motor in a B16 stamped block... NICE!

 

go with 84 sleeved block. the bore gives you more displacement than the stroke, dont make me break out geometry. as someone else said you can use a stock ls crank, and custom rods and pistons and have thebest of both worlds. i think honda tuning did it, although they used the probe kit.
