It does not matter what holes.

Fidanza is not talking about any errors.

Your balance shafts could be out of phase in the most extreme condition if you were in there messing with the timing belt at all.

The holes do matter, one is marked for evos and the other is for dsms. Use the wrong hole and you will be a few degrees off. If you don't believe this, go compare a stock dsm gear and stock evo gear, the tdc mark in relation to the hole is slightly different. Fidanza had 2 holes on the gear for a reason, ask someone there who is knowledgable.

so can someone post pictures of dsm gears vs evo gears to compare so that we can gain the knowledge for the betterment of the evo community?

I agree with this statement. I have comparred the dsm gears to evo gears. Car will most certainly run fine, but each cam will be a few degrees off. It is possible for a setup to actually like the misaligned settings.

EDIT ! please look at my following post.

I have spoken to two different techs at Fidanza. The phone number and extensions are posted in this thread for a reason. Contact them yourself and have your debate with the manufacturer.

so have you come to the conclusion if the fidenza gears are safe or not?

I just checked the gear differences on a dsm engine. I set the stock dsm gears at tdc, locked the cams in place. then swapped in a stock evo gear. Everthing still lines up. So my above statement is incorrect, and the techs at fidanza are correct. The two holes in the gears are simply 90 degrees apart. Since there are 48 teeth on a gear moving the hole 12 teeth is not an issue.

What is nice about this is you can use dsm cams in an evo or visa-versa. You just have to move the timing marks 12 teeth to the left or right depending on which switch you are making.

thats what i figured. i checked mine out last night because i was in fear of them having the timing problem like the one from post 1 (which they don't. i also used a level surface and a level to check that they were true which they were). the tdc mark above the evo hole is 90 degrees off from the timing chart. it shouldn't matter what hole you use as long as you set the timing via the chart

Why dont people just degree thier cams? Seems that would solve any problems associated with this anyways. Also, as for the gears whining, wiggling or vibrating. I had the same thing... this was the result:

That is a better version of "Whats wrong with this picture"

Wow, looks like you overtorqued the retaining nuts... J/K

First one I have seen that broke.

For the record Fidanza has agreed to swap these out, however their blue and reds are out of stock.

Guess it's silver time.

yeah. i looked at those pics and thought the same thing. the cracks look like they came from way over torquing the nuts. what did you use? 45 pounds of torque? lol. supposed to be a max of 15.

TTP Engineering

iTrader: (465)

Um, no max of 3.75 ft-lbs=45 inch-lbs. 15ft-lbs will break all the nuts off.

yeah i knew it was 45 inch-lbs. i never did the math to convert it though. i had read in other posts that it was 15 lbs max. i never did that conversion either. i never sat there and thought about it. just thought they were the same value. just on a different scale. good to know though. thanks.
