What a difference!

I am hauling a lot more ass than I was now!! whew! I just got my opel started again after a few months of gutting out some parts and it flies!! I added the sprint manifold and ported my intake manifold.

I am running the sprint to my stock head pipe with no muffler right now and its loud!! but I did that so I can drive it to the muffler shop and they can custom fit my side pipes. It seems with the head pipe length the backpressure is fine..

but what a difference! I recommend this to everyone! :D

I notice that you didn't use the wedge shaped piece on the intake manifold floor, is there much of an advantage of adding it?

My impression is that the wedged piece on the floor of the intake manifold, in addition to the reshaping the starts of the intake runners, will decrease the net interior volume of the intake manifold, and thereby increase intake charge velocity, which improves throttle response and torque.

bob did a fine thread about it and others came up with diff takes to do it

Ahhh yes! I have seen these threads

actually those threads got me to where I am today! That wedge seemed a bit tough for me to fabricate so I opted not to do it. Maybe in the future -

I couldnt have done this work myself if I didn't have this site!

bq97, I have left the jets stock from when I bought it. I really need to get a colorado opeler to help me with that, Im sure I can bring some more power out of it with different jets here in the mile high. I got lucky with my motor being the high compression 1.9 - I had no idea until another opeler looked at it.

My 38 was about 250.00: killer deal from a land cruiser shop, brand new - I'll try to find the link.
