itr pistons in ls long block = piston slap and eventual cylinder failure?

is the dome jus too damn tall?anyone running these pistons with a non vtec head? speak on it peoples

 

I'm also wondering this, I am running a ported and polished non vtec head on my b18 with crower stage 3 cams and I am looking for more compression.

 

i've seen ctr's in a ls block itr would be fine...the cylinders should not give unless being boosted on somehow...or unless you have alike a .20 over block...or something...and if you put that together with stock pistons ur stupid...

 

so ls rods itr pistons (oversized .25) in ls block=stupid?

i also jus saw on inline four that toda makes gaskets that are thicker then stock to lower compression that might give jus that lil mm that the piston needs to fit in nice...

if this set up won't work im considering gsr cranks and rods and ctr slugs....

 

We have done LS block CTR pistons with non-vtec head and it ran very well, don't understand why the ITR pistons would hit! You might want to check if the ls head that you have has been milled alot, thats the only thing I could think of.

 

wierd yea the local guy at a shop should it wouldn't work (he was a tech at honda) i dunno what to do. id really like to talk to people who have done is and if worse comes to worse actually measure the bottom to the top and get an idea

 

it works fine. Piston slap is when the pistons are loose in the cyclinder walls and making noise.

thank you for clearing that u i though it was whel there is clight contact between the valves and the piston. lol i guess that would be piston you jus got tko'd....... and not jus a slap on me

 

[QUOTE=ambition]so ls rods itr pistons (oversized .25) in ls block=stupid?

i meant that using stock bore pistons is say a .25 (my bad) block is bad there is gonna be slap...

 

if you put stock bore pistons in anything that is bored out you wont get slap you get mad blowby and 0 compression is what you get....there is no seal.

CTR piston in ls block is fine I had that in my old b18a. itr has less dome than ctr and less that p30 and pr3 for that matter.........ITR is the least of your worries.

thanks for the replys everyone! im looking at a newly rebuilt ls block the sleevs were bored .30 is this kida odd? is it too much of a bore? will i get the right seal if i use ctr/itr oversized pistons(.25)?? by my math thats still .5 of a difference.......
