will i notice any significant power loss by using the dx cam, fuel pump, and distributor rather than switching all over to Si parts? napa quoted me $130 for an 86 prelude fuel pump which would probably be my best bet for a pump. Trying to save cash where i can here but if it'll be a significant difference i'll spend the money for a new pump smile.gif

You will have to downshift while going uphill. And yes the dx cam is ground different than the Si cam is. So from what I have been told, it will decrease performance. Plus, what are emissions like in your area? You may not pass emissions without utilizing the auxilary valves.

The entire tool selection at Sears or the contents of a Snap-On truck will do you no good if you do not know how to use them.

I use an carbed Accord pump with excellent results. I think the carbed prelude one is the same.

Can you use the DX cam in the SI head? The Si cam is much better though.
