Camshaft Spacing

FriendlyTurkey · #1 09-04-2009, 05:13 PM

I'm looking at doing billet camshafts for my EG33 with four cam gears driven off the timing belt much like the EJ205 and EJ257. Has anyone measured the camshaft spacing compared to the EJ DOHC heads? The idea behind this is to eliminate the internal gear drives.

Here is an EJ with 4 cam gears.

I'm putting a EG33 in the back of a VW golf I have. Mid engine and ~2200lbs I estimate. These pictures are with a EJ18 mock up. I have the EG33 in R&D build up stage.

Found this article that was interesting. Note the four cam pulleys on this prototype for the EG33:

I have been meaning to toy with this idea for a long time... Adjustable cam gears are always nice. Not to mention you get rid of the scissor gears. You would need to use reground exhaust cams for the intake cams.

Have you verified the clearance between the gears Tom? I haven't had a chance to pull my head part to give this a try.
