Default Turning Up A 12 Valve

Ok, ive searched though here figuring id find a thread on this but couldnt find one.

A buddy just bought a '98 12v and he wants to turn it up. I would like to find detailed instructions on how to turn up a p-pump. From turning the starwheel to grinding the fuel plate, everything. Pics would be great too.

Thanks in advance.

When I ground my plate I used a 90* air powered die grinder with a cone shaped carbide bit. After I was done I used a wire wheel and sand paper to smooth it out perfectly. Alot of guys just use a grinding wheel. Use the chart above and make what you want. a 10 or 100 seem to be the most popular.

He wants to go all out. If he needs to buy a turbo to keep it cool he will. As for now, he wants fuel and lots of it.

yeah there's always that one too.

Wyo,

Get him to pinpoint a number first. 400, 500, 900? It's easier to tell you how to get there if we know the destination.

Yea i agree thats the only way to go, then slide the AFC housing forward and take the spring out of the back of the housing

Thanks guys, we got her turned up, he just wanted to slide the plate up all the way for now. Way better power, barely any smoke. We'll probably be grinding the plate soon because he has the bug now .
