I have a set of 272 cams for my s13 sr. I have read that the exhaust cam will be way off timing with the stock sprockets, does anyone have knowledge or experience with this?...I have done countless searches, Thanks

don't quote me, but i thought that was only for true for certain batches of the cams that were produced....

don't count on it tho!

I've heard that the timing is usually off with these cams. I had a friend who has a set of 264 and his timing was off from the get go...

Yeah, you should buy a set of cam gears to go with those cams... that's what I did. After that, put the degree wheel to time them properly!

Thanks for the responses guys. I will get a set of sprockets, but I dont have a degree wheel because I bought the cams used. Do any of you know where I can get one or have any other suggestions?

Timin is off big time. You need adjustable gears, a dial gauge, and a degree wheel. Took me 8 hours to get it all figured out. Good luck!

8 hours to get the timing figured? hopefully i can get it done quicker than that. ^^^what was your timing before adjusting your sprockets? which BC cams do you have?

tacoboy · 04-26-2010, 04:44 PM

272's. Its a VERY strenuous process, and you need to know how to do all of the math in order to get it right. Remember, it's not crank timing, its cam timing, not as simple as moving a CAS...

FYI, degree wheels don't come with a new set of cam... it's not like a clutch alignement tool...

And also, you have to know the entire process, and make sure you know it by heart, understand it so if something happen, you will know why. It also takes a dial gauge. If you plan to do that yourself, I hope you know how this work.
