B series vs H series

[GWInquisitor14]

Ok so today me and this other kid in school kinda got into a lil arguement on which engine is better, the b series or the h series to turbocharge. Now I'm saying the H series cuz its got .4 more Liters so you can get a lil bit more torque and w/ 4 cyl u want as much torque as u can get. Hes saying the B series because its got a better built block with thicker walls nad better internals. Well were were talking about both vtec engines, so like a GSR motor vs Lude Vtec, not the LS. i was saying there ins't much of a difference. Then he said that the H series has an open block and i dont really know what htat means so i was stumped there. So if you could just kinda clue me in on whats better and why.

An open block (or open deck) is one that there is a gap all around between the sleeves and the block itself. But not all H-series motors are open; my buddy just got his H22a sleeved and it was a closed deck. Not to say that there aren't open deck h22's cause there are. I don't know how well the stock internals of both the GSR and H22a are compared together. But if both blocks were sleeved, low compression pistons, rods, etc; then I'd say the H22 just based on the 15-35 extra hp.

As far as I know, all B and H series motors are open deck. When you sleeve the motor, yes they close the deck. It would be dumb to have reinforced sleeved with a open deck, kinda defeats the whole idea. It is common knowledge that the internals of a B series are stronger than the H series (espicially the ring lands) and yes the cylinder walls are thinner. That doesn't mean that the H22a will perform weaker under boost, its all in the tuning. I have seen numerous cases where with both B and H series motors will push 400-500hp bone stock. Is it smart, not really but I can be done. My vote is for the H series considering both motors are sleeved and have forged internals. The larger displacment and stroke gives the h22a alot more torque compared to a b16-b18.

So when they resleeve the block, do the old ones slide right out then new ones are put in and those ones touch the side so the cylinder walls?

[DeleriousZ]

well when they sleeve the block, they usually re-bore the cylinders, then drop in the heavier sleeve that is made to fit the bore size you selected

So pretty much ud take the H series over the B series?

i believe u guys are missing a very important question. what vehicle is the motor going into? for the strip, the h22 is a very good idea, but good luck trying to install it. also the wieght of the h22 in a civic or integ is not good for a daily driver especially on the turns.

i for one would rather have a b-series motor anyday, its not too big so theres no cutting or fabrication. if u want a bigger displacement, u can always bore, stroke and polish it, and of course the internals in the b-series are stronger. basically u just can't go wrong, whereas the only main benefit from the h22 is the displacement and extra wieght on the front end to help put the power down to the wheels on the straight away.
