Hey Guys, I am in the process of building my 2.4l and have done a lot of reading/research here on the forums. Since I am a bit paranoid and would like to just get a confirmation that I did the timing correctly, I wanted to put a quick post up and just get it verified. These are with Fidanza cam gears and s3 cams .

The crank mark and the oil pump mark are lined up. (not shown in picture)

In the pictures below, The black mark on the cam gears is lining up with the mark on the valve cover. (for the exhaust side I got a bad angle). We took the cam gears and retarded it(towards the intake) approx 3.75 degrees.




Here is the exhaust side..same concept!







I'm hoping I got it right.

Thanks in advance!!

 

They are not correct, you should be lining the centerline mark on the cam gears up with the valve cover marks, it is the mark on the purple/red part of the gear underneath the hash marks 'that are on the black part of the gear' The gears need to be rotated 90* counterclockwise.

 

90zcrex is incorrect, the fidanzas have dsm dowl hole and evo dowl hole. If you look closely they are in the evo dowl hole, and the fidanzas turn opposite of the AEM gears, and the fidanzas labeled a half tooth off from jump street...

the camgears look to be set up correctly...

 

thank you for your response! Greatly Appreciate it!

 

Oh sorry didn't realize these were different for evo and dsm.

 

The picture shows where the marks should line up on the EVO cams.

 

You are correct on how the cam gears are incorrectly installed. The fidanza ones are incorrectly marked for the EVO and DSM holes. However, in the picture shown, where the cam dowl and marks line up with the valve cover are correct.

This is assuming that the crank is lined up as well.

 

The picture below shows the black circles being lined up correctly but the blue circles show that the timing marks are clocked wrong. In other words, leave the cams where they are, move the gears to the other dowl hole and set your timing.

 

What you guys are failing to see is the fidanza gears have a dsm hole (not labelled) and evo hole (labelled evo) and when in the evo dowl pin hole the toming mark is 1/2 tooth off... they are terrible gears period...however in the picture his timing is correct regardless of how other gears are set up these are "special"

 

So very often i c on here mostely every one that post says degre 3.75 . This us not correct on all 4g64 blocks as it depends on the cams tdc and also if the block or head had bean resurfaced . I had a machine shop build my bottem end and assembled my head and we came up wit some different numbers other than "3.75 "

 

When in the evo hole they line up just fine when layed over top of the stock gears(albeit the hashmarks are 90degree clockwise, but that's by ****ty design), but when in the dsm hole they are a half tooth off.

 

Same thing. Just a little paranoid. people say just turn it over a few times and youll be good if nothing hits, BUT my lifters are bleed so it doesn't give the valve the full extension.
Just need piece of mind. 2.4 94 galant dohc gs belt








Thanks guys

 

If I remember right you actually need to go the other way with the cams with a 64 belt.

 

you need to retard them, which my timing shows I did. I was more inclined to make sure that this is indeed setup correctly based on other people that had this set this way as well

 

Your gears are off. Im guessing you are running the fidanza gears. You are a half tooth out. Based on your pictures, the part with all the timing marks is on the side. They should be at top dead center.

Refer to my previous post on the marks and where they are circled.

The HKS cam gear I posted is correct. With the 63 belt you advance the gears and the 64 belt you retard the gears. This does not change your cam timing. This only makes up for the added slack in the belt depending on what one you use.

If you cam dowl lines up with the mark on the valve cover, your cam is at 0* of cam timing. Then you can start playing with the cam timing to make more power or what not.
