ok put my zex 59300 cam in my d16z6 today. im using a stock cam gear. checked to make sure the cam timing was perfect like 10 times. everything lines up right at TDC.

my valve clearances were a mile and half off! the bottom of the screw is at like the top of the nut.

but what gets me is when i went to set my ignition timing. i had to advance the dizzy all the way to the front and it was still 2 degrees short of 16 degrees. so i had to drill the holes out on the dizzy dizzy so i could advance it more. advance is towards the front of the car right?

but i know people usually get a adjustable cam gear when getting a cam, but i thought stock cam was perfectly fine? there are tons of people with this cam and ive never heard of having to drill the holes out on the dizzy so you can achieve 16 degrees. is this normal with this cam?

anyone have stock d16z6 cam specs?

Are you sure you got the 59300 cam, and not the 109300??

Sounds like you have the 109300 cam??

no it said 59300 on the cam and on the box. bought it brand new.

bump.. wtf

The valve clearances being off after the cam install is normal. They need to be readjusted.

Now the dizzy adjustment.....I have the same damn problem and I still don't know what's causing it. I have the ZEX 105300 in a Y8.

If you are using an obdI chiped ecu setup for engine management, the difference between the cam timing if the z6 head and the Y8 head is different, the cam gear of the Y8 is 1/2 tooth off causeing the timing to be off.

There is a good discussion on pgmfi.org on this subject right now. http://forum.pgmfi.org/viewtop...t=135

it's a little confusing, but it may hep you..

mike93boost

that is not my problem though. i have a full z6 engine and the z6 59300 cam. had to drill out the holes on the z6 dizzy to get timing set right.

i just want to know if this is normal when using a stock cam gear with this cam or what??

other than that this thing runs like a bat outta hell now.. huge top end gains..

drintegra

Yeah sounds like you got the wrong cam. I have a d16z6 with the correct cam but the Y8 camgear, and for me to set the cam at tdc it was off at the gear by 5 degrees.

no i have the right one. it says 59300 on it. you have yours wrong because your using a y8 cam gear. the keyway slot on the y8 gear is offset about 4-5 degrees compared to the z6 cam gear. timing is way different on y8's.

i have had this problem on my old motor and a friends motor (both sohc), the timing belt seemed to line up either a little advanced or a little retarded, but never dead on. if i could not get correct timing out of the dizzy then i would move the belt one tooth at the cam gear.. problem solved. the timing would be right in the middle of the slots at the dizzy. and the belt would line up a little to one side or the other. always ran like it's suppost to (250+ hp on greddy kit)

have you called zex (or whoever you bought it from) ?

the only difference should be the lift/duration of the cam, if the timing has changed, i would say its a wrong cam.

maybe it was mis-stamped?

well my timing belt line up perfectly TDC..

Tad

yeah, probably a cam for a different sohc motor then.. like maybe a 1.5 or something.

Which would explain why with everything lined up at tdc, using the stock cam gear, CAM timing would actually be off.

Might have to send it back or get an adjustable camgear.

this is just a guess though...

mike93boost

well my cam timing is dead on. its my ignition timing that was the problem. i had to drill the holes bigger in the dizzy to get the igniton timing at 16 degrees.

car runs and drives great though..

Tad

oh I see,
feel a boost in power over your stock cam then?

make sure u got the right one
the 92-95 and 96-00 ones are 1/2 tooth different
and 1/2 tooth is 4.75 cam degrees wich could mean thats what off timing and adjust wise

drintegra

I know about the 4-5 dgrees being off I put the y8 cam cause it was free, but In your situation you have the right camgear and, presumebly the right cam, yet your timing is way off consequently that is caused by either your cam being off or your gear. It has to be one or the other, or re-check the timing marks on the timing belt side to make sure everytihng aligns. ALso milling will cause your timing to be off just not that off. good luck

mike93boost

checked the timing belt side a good 10 times. everything lines up TDC perfectly. its not a tooth off, ive done that before and it barely ran.

mike93boost

this is going nowhere.

they usually engrave the part number where you line up the cam and the cam gear check the ends. I know for my cat cams they did.

yea i know..

THIS IS A 59300 CAM PERIOD.

mike93boost

lets say i have the y8 zex cam. what exactly is different about it? i held it up to my stock z6 cam and it looked identical. i know the stock y8 cam gear keyway is 4-5 degrees different fromt he stock z6 cam gear.

basically. cam timing is dead even at TDC and ignition timing is at 16 degrees even though i had to modify the dizzy. is this okay?

drintegra

no cause you the dizzy is overall timing the cam is ofcourse cam timing. You need to adjust your gear 5 degrees one way or the other. Just trying to help and it is worth a try. I did this and mine workks fine.
