I have done a ton of searching and stuff, but some things i dont know.

I am going vented opti, cloyes timing chain, and csi h20 pump.

a.) I know i need a 95 timing cover, pigtail opti adapter, 95+ opti spark itself. Now does the new opti come with the vent lines? And if so, where do they run to? I thought they went to the intake manifold, but where do i attach?

b.) What cloyes chain do i need? Can someone give me a part number?

 

Cloyes double roller chain part # Roller Chain 220-9-3145
Vent attaches to the CAI...Mine is right in the elbow...

 

>I had to get mine seperately .

 

You are aware that you will need a '95 up cam or modify your '94 for the vented opti to fit. Here's a site with explanations.

I know about the cam, thanks for the heads up though. While i am at it i am replacing the cam, it just wasnt releative (well i forgot about the dowel pin) to this post, so i didnt mention that.


On the vent lines, can anyone be more specific on how it attaches? Is it with a hard plastic 90º elbow? I think i have seen one of those on our cars before, but didnt pay too much attention.

Part numbers for the vent tubes please?

 

BTW, Hi jeff! Wlcome to the "other" board. lol

 

The number for the opti vacuum harness is 12555323. The thin vacuum line connects to the bellows, like you said, and the thicker one connects to the intake manifold on the drivers side.

 

do i have a spot on the intake manifold, or will that have to be drilled and tapped?

You guys are great!

 

On the '95 it taps in under the brake booster vacuum hose. Maybe you have a plug there. If not, get a T fitting and connect in to the EGR vacuum source, to the left of the brake booster line

 

will do, thanks!
