low or high compression?

turbulence23 · Post by **turbulence23** » July 27th, 2007, 5:48 pm

i recently places a ZE in my mx, and gotta say... its sweet

but what i was wondering, how can i see if i have a high or low compression ZE??? ( maybe thinking about boosting)

it's a curved neck ZE, but how can i tell for sure if it is high or low compression? do i need to get the head off?

did it come with curve neck or straight neck manifold and what cams were in it?

it came with the curved neck...

KL31 is written on the cams if i think about it, when i changed the valve gaskets i looked at it, and believe it was KL-31..

If it has kl31 cams and its a curve neck, then someone swaped the curve neck on it. therefore its got the 10.0:1 compression pistons

u could run a compression test just to see, but that doesnt tell u for sure...
But still a good thing to do...

so kl31 cam is for highe compression, and KL.. is for low?

there is not a possibility to boost on the high compression at tall?

yes there is a way... Your rods and valve retainers are weak though... You can build a kl-de/ZE hybrid and then turbo it. Or just run your ZE at 6psi max stock internals(not much safe over 30k miles...) Go on probetalk, forced induction section, and reaD!(archives)

ya ya im waiting to see if my ze vlows up, im getting a de or millenia ze and going hybrid. Those things are a dime a dozen locally.

not sure where I got this but somebody on this forum made it...

gives compression stats on these stock motors
