hey, just wondering....what cams are in the ZE, are they kl31? if not what are kl31's in? thanks

KL31's are KLZE cams in the straight neck manifold ZE. The curved neck KLZE's have KL01 cams.

That's why most people say, if your going to buy a ZE buy a straight neck, Because the 31's are more agressive

more agressive = more hp

yeah but they do have a problem with crack retainers

I know my curved-neck ZE has 01 cams, i've seen them myself when i removed my valve cover to polish it...but it was a known sacrifice when i bought it, the car is still fast as hell. With some research, I realise that's it much easier to get cams afterwards than it is to get an intake manifold. Most companies or even wreckers will not part the intake manifold without the engine.

Personally, I haven't been in a huge rush to replace the cams...it would be beneficial for drag racing since the max torque (4800rpms, KL31 cams are at 5500rpm) is lower the rpm range that the car stays in while racing, however for autocrossing which I would like to do next year, would use more lower-end power, so they may be beneficial, who knows.

Ideally, I would love to try some Interprep cams and get some 11:1 pistons.

So what significant HP difference is recognized by having KL31 cams over KL01 because I see the torque/powerband. I've heard that Interprep name before on this BB. Is this a viable alternative instead of getting KL31's.

Actully moving the KLZE cams to differnt than stock postion's
gains can easily be made, its not so much the duration of the cam
more the opening and closing and center line relationship to the crank
that matters and oh going for longer durantion cams are a waste of time.
260's would be the biggest id go on the KLZE

Note, once you start playing musical cam settings this is when you want
TOTAL adjustability and to do this on the k8/KLZE you have to do a
bit of machining though the cam gears are only pressed on the cam's
themselves the exhuast cam can be setup up to be totally ajustable
though you are going to have a noisy gear set as the friction spring
gear has to be removed.....

So if anyone has any answers to where i can get a straight neck klze vs. the curve neck where would i go about getting the straight neck. someone help because i am going to order the klze within the next few days thanks.

You can get either engine anywhere they sell jdm engines. Most likely they wont know what you are talking about though. Go to noyanusa.com and tell them you are looking for a straight neck ze and they will know what you are talking about and they are a reputable place.

Could you put KL31 cams into a curved neck for a performance increase?

yes

correct me if i am wrong but i have heard that putting the kl31 cams in the curved necked klze can cause the rods to weaken. i have heard that the engines tend to go more easily if abused more often. not saying that the engine with the kl01 cams would not go if abused.

How can a change of cam's cause a metalurigal change in the
base componet of the rod's.....

Answer B.S.

Peaple might have thrown a rod cause of over rev's but more
commom with this engine is lack of oil to the thrid bearing and rod...

ya and the kl01 klze is the same exact thing as the kl31 klze...just different cams..why not swap them
