i have a lot more ??? thanks for any help.

1. A p-pump is an inline injection pump on the 94-98 12v engines. The advantages of the p-pump are ease of adjusting and changing timing with proper tools, more rpm's with the proper govoner springs, and the biggest, more fueling. Your end result horse power goal and how much money you want to spend on an engine is the thing you need to figure out first.

2. 4b's are good engines. They do take mods well. The biggest complaint i know of on them is they tend to vibrate a lot. This can be helped and reduced by a fluid dampener, or an ATI dampener.

3. The manifolds flow more than you'd think. Plus keep in mind the exhaust pressure is usually the same as boost pressure or more, so those small ports help drive the turbo harder in stock form.

What else?
