waz up?
I have a 98 prelude.... MY question is if the h23 block has to be resleeve for aftermarket pistons. I planning to run my direct plate system with 150- 175 shot. I heard if i were to place a h23 block on my motor , i was told that i would gain more TQ to the wheel. i just want to know if this a good idea or should i think about a different route. My plan is a h23 block with JE pistion ,eagle rods, and 150 -175 direct port plate system

The H23 will make more torque, it has a longer stroke. I made 160wtq with an H23 VTEC setup...which is about 20wtq more than most comparable H22 all motor setups...

As long as you're getting aftermarket rods/pistons/sleeves it will hold up, but I wouldn't want to rev it tooooo high.

 

if i were to use ARP bolts ( i think hat the name) for the rods to hold better would it run a lil bit better and safer. When i get aftermarket pistons for the h23 do i use the H23 compression ratio or do i use the h22?

 

stock tq rating on the H22A is 152 ft/lbs

 

it's not the strength of the end caps that prevents higher revving on the H23, it's the rod/stroke ratio that increases piston speed over what is recommended

 

uhhhh, drift 152 ft lbs of torque is at the crank, he was stating that it was at the wheels.

 

Yeah 160 at the WHEELS. That's about 190 lbs-ft of torque at the crank.

And the stock rating on an h22a is 158 or 156 depending on the year

 

P.S. Eagle does not make rods for the H23

 

does crower make rods? SO what compresson do i use?

 

Here a question does h23 block need to be relseeved? also what would happen if you dont resleeve the block w/ aftermarket pistons?

 

what misc. parts are need in the h23/h22 vtec swap?

 

Si(h23a1) = 156 lbs/tq
VTEC(h22a1) = 158 lbs/tq
