hey guys, ive posted up some tonight and this week, though i just got my 94 little over a week ago. i am not new on things EXCEPT the p pump. tomorrow (well later today/saturday) im planning on doing my fuel plate and was thinking/and advised that a 100 plate is best way to go. ANYHOW, i have a friend who does metal work, and am thinking maybe to go to him with the stock plate and have him make me a copy (or two even) so i can grind it down without fear of messing anything up...

so any detailed advice on the p pump mods is greatly appreciated, as i plan on bombing the truck ASAP. already have gauges installed (did em day after i got the truck) so i can monitor any changes-

thanks in advance,
-jeremy

 

jeremy-

i ground my stock plate myself. first and only one so far tho. i used a cone shaped carbide bit in my 90* die grinder at work. i took my time doin git. let the grinder feed itself instead of me pushing it. just make sure you get all the burs off it so the arm isn't catching on it. i'm pretty happy with it. it's kinda like a 10 but the hook at the top is smaller. i'm also including a general reference sketch of the basic profiles. it's been floating around various forums for years.

 

Thanks for more info johnny- havnt gotten around to doing the plate today, though it will be soon

 

Jeremy, it is not hard to do at all. Just take your time and you will be fine.

 

not sure of what you mean here .do i cut off the pressure from the waste gate completely or restrict it, thanks

 

whats the deal with the afc washer?

 

you can do either, but if you get rid of the wastegate circuit on your turbo you'll have to learn to drive by your boost gauge. keep the boost under 35 psi!!

the boost elbow screws into the turbo side of the line feeding the wastegate actuatator. there's a little allen head screw on in. i'd recommend this route myself.

 

so what do i do with the allen scew ? and you say driving by the turbo boost sounds too confuseing i may forget to on many accasions

 

here's a DIY boost control valve that gives you infinite control over the wastegate.

 

it may be confusing. that's why they ccreated wastegate systems. Lol. basically you'd have to keep your eye on your boost gauge and make sure to keep it under 35 psi.

with the allen screw on a boost elbow you screw it in and out. this increases/decreases the holding pressure of your wastegate valve. the harder the valve holds the more boost you build.

the valve set up that chris just posted would be used insead of a boost elbow and would cost you about $5 to build.
