So I just picked up a del sol for my dd. d16y5 with z6 cam, gear, and rocker assembly on a p28. traded some rpf1s for it so wheels for a car. good deal. anyway... my question is how many degrees does the z6 cam have to be adjusted in the y5 head to compensate for the timing difference? things a pretty quick little single cam after about 2 to 2500, but GUTLESS under it. I know it has to be adjusted to compensate, my question is how far advanced or retarded? Im pretty positive it needs to go advanced, but correct me if I'm wrong..

 

Come on someones gotta know???

 

Congratulations on buying someone else's headache.

 

Don't understand why you aren't timing it properly instead of guessing.

 

Ok I wasnt asking for anyones hating. Its a car for wheels. And its pretty clean and sohc. I needed a dd because my 12:1 gsr wasnt cutting it mileage wise and I dont want to put all the miles on a track season motor. Im already on axis ogs so im good in the wheel dept. Anyway....

For any who cared to know I advanced the cam gear one tooth and tbe distributor all the way and showed at 17 atdc so im guessing its around a 7 degree advance. I was trying to see if anyone had the exact number so I couod do the math until the cam gear comes in. But for those who dont know the z6 and y5 cams begin lifting at different times so the timing with the cam will run like its a tooth or 2 off when everythings lined up perfectly. So you have to advance to compensate. On a stock gear 1 tooth + distributor advance should work untio you can get a gear. Then im guessing its around a 7 degree advance. If I find the exact number ill post it if anyone else can find it please post.

 

use the y5/7/8 oem gear. problem solved.
