Now i'm goin with a set of MPH N/B Cams or VT 2's, and goin to a 100-125 dry shot. I know the stock injectors are only good to about 315 rwhp or so... So i was wondering... what size to step up too? Was think'n the #30 for a minimum, and also what fuel pump do you guys suggest... i was thinking the SVT Focus pump. Where can i find install instructions and where are some good prices for the pump and injectors. Any other suggestions would be great.

Here's a link to the "how-to" for the Focus Pump. Randy Stinchcomb over at Modular Depot has a good price on them usually.

http://www.freewebs.com/dndgarage/focuspumpinstall.htm

Doing 36# or 42# injectors right off the bat would probably be more benficial to you, especally since based on your mods in the future, it sounds like you have some big plans.. I'd be surprised if they stopped with the 100-125 dry shot & cams.

Remember you'll have to get the MAF recalibrated if you do bigger injectors, so keep that money free.

Where do you plan to cut your setup off at hp wise? If you order the cams from MPH, just order the fuel pump from them as well. The install is cake, it's a direct replacement for the stock pump.

Well i would like 315+ rwhp and 350+rwtrp N/A and 415+ rwhp and 550+ rwtrq with spray... a 100-125 shot and MPH cams should just about put me there.... and i dont have ud pullies, tb or plenum or intake, elec. water pump, and still runnin stock cat back!!! So its very attainable.
i made 280rwhp and 310 rwtrq right now N/A and 315rwhp and 405 rwtrq on a 50 shot. Yes its a 50, my car loves the spray and makes big trq for some reason.

i would like my car to be a very fast street car that handles well and looks good...

why do you ask where i want it cut off at?

The cutoff should drive your injector choice. You don't want to setup for 350 hp and then have to sell them for larger injectors 6 months from now. If I were you, I'd go w/ 42's, they should handle the HP you're looking for.

Randy Stinchcomb runs the Ford Parts section (or Liberty Ford) on the modulardepot.com forums. You have to register to post. I was referring him if you needed the focus pump.

http://www.modulardepot.com/forums/forumdisplay.php?s=&forumid=21

www.BuyFordRacing.com is about the cheapest place I've seen for 42 injectors. I've purchased them from twice and no problems either time. They have a special for a 90mm LMAF and 42's for $319
http://www.buyfordracing.com/shop/product_info.php?products_id=532

or $260 for 42's
http://www.buyfordracing.com/shop/product_info.php?products_id=360

There is always ebay of course, just have to do some research and make sure it's a reputable seller.
