4g64 timing help
Hello every one,
Let me give you a ba ground on this built. I blew my 2.0 and decided to go with a 2.4 4g64 I'm doing the 64 with a mivec head and an Evo 9 timing belt. The machine shop assembled my motor and timed it with a degree wheel. Can you guys based on these pictures tell me if I need to retire or something again the machine shop degreed my engine based on the cam card that came with my gsc S2 cams. Please help me out befor I install the engine or is there a way that I can tell everything is timed good? Thanks In Advance oh and my cam gear is fidanza if that helps.

Looks off to me.
The intake cam mark should be perfect to the valve cover mark, Its either on or its not.
And for the intake cam, even if it needs to be changed cause of milling or headgasket thickness. The mark should still lign up to valvecover.

Yeah i agree timing is off. The cam marks if degreed should line up just like stock. I used a 4g64 timing belt on my build but the lower timing stuff is off as well. I am sure you did away with balance shafts, but i would have set that up where everything mark wise lines up. How many times did you turn your motor over? I think it is suppose to be like 6 times or something lilke that if i remember correctly.

The machine shop is the one who did everything they trimmed it and assembled it. I told the shop about the whole -3.75 degree for the exauhst cam. But the owner kept telling me we degreed the engine based on the cam card and also told me top dead center is top dead center and that we degreed the engine based on the cam card. I'm all confused I'm not sure what to do. What they told me was that the could get it as close as 1 degree to top dead center. I called GSC because that's what my cams are and I told them about the 1 degree top dead center and they said that is very good given the fact that you're doing a 2.4 and that there are so many moving parts involved. So now I am all confused

why is the exh cam not installed using the evo hole of the cam gear? i can see the dowel in the other hole. the crank doesnt appear to be @ tdc either based on from what i can see with the notch in the timing plate. i forget which way you need to set the cam on a 4g64 with an 8/9 belt. simple search.

Well you need to find pics with the fidanza cam gear like you have, the advance/retard goes the opposite way as AEM/HKS gears, and each gear is a half tooth off from the get go... I hate fidanza gears... it is weird that it is in the DSM dowel pin hole as well...
For set up, the exhaust gear needs to be around 3.75* retarded if you are using a 63 belt, 3.75* advanced if using a 64 belt...

See that's what the shop told me they said the cams are degreed all you need to do is to line up the I take and you're at top dead center. They told me that the exauhst Sam is a degree off or degree close to Top dead center. I really want to put the engine back in the car but so t want to do it and everything is wrong and I have to take it back to the shop. Does anybody have a fidanza camgear 2.4 set up so I can see what I need to do? And can someone explain to me what's the point of degreeinng the cams? I mean if your timing is going to
Be off what's the point lol
Thanks everyone

re read post.
Ive never degreed a motor so my answer is probably useless.
Now that I re look at op pics, I guess if it was degreed, timing looks ok maybe 2 degrees advanced?
