What should i do next for more power?

[Ctallman]

I bought my truck my senior year of high school, (3 years ago) when it was 2 wheel automatic. I put an NV500 in it a year later. Then last winter i bought a parts truck, put the dana 60 under the front, 205 t case transfered from 23 to 29 spline, swithed the transmission from 2 to 4 wheel, and had the driveshafts cut & lengthened. After that i turned up the pump, got PODs, a PDR HX35, 16cm housing, open air intake,south bend, & gauges. Im looking to get 4 inch back to my dual 5'' stacks now. What can i do after this? oh yeah, any good exhaust websites for 4'' that actually list a 1993? Ill try to get some pics of the "pipes"!

You're ahead of me, so these are just thoughts for your consideration:

1. ATS or better exhaust manifold & porting.

2. VE pump 3,000rpm (some call it 3,200) governor spring.

3. O-ring the head. Wherever you're going, you're going into the territory that needs it. Put in the 60# valve springs while you're there.

4. Dual turbos? Custom rebuilt VE pump for more fuel?

Hopefully, one or two of the high-torque folks will chime in on this one.

1: Sounds good as far as the truck. If you already have stacks, I would just piece together 4" back to the stacks. You can source this from a local big rig parts house, maybe a Napa parts house. You'll need some flex, a short radius elbow or two and maybe a few inches or more of straight 4" tubing after the t-case before going up to the stacks. I believe one site for exhaust pieces is www.airflo-online.com or something like that. For a 4" kit with 3" downpipe straight back/no stacks www.bigexhaust.com. I just got rid of my stacks and went with their kit minus the downpipe as I built my own 4" dp since I have a 4" turbo.

2: 3200rpm gov spring is a nice cheap mod. Grind your afc fuel pin for more fueling.

3: Hx40 or HTB2 4" turbo would be nice.

If you want to stick with a single turbo you can do an HTT stage 3 or 4 upgrade. Easy to do and relatively inexpensive. My son and another friend locally have done this (on 2nd gens) and it supports hp into the mid to upper 300s.

Past that ya better listen to bgilbert and some of the others who have disappeared into the tunnel :-laf

Bomb on.

Thanks for the info, ill start with the governor spring and 3 piece manifold, whats the dead KDP mean? i havent read up on that

 

[bgilbert]

I'd say hold off on the high dollar ats manifold. Power can be made with stock. Only way I'd upgrade is if mine was shrunk and or cracked. The $400 can go somewhere else. Port and polish maybe to the stock if you wanted to go that far.

A KDP (Killer Dowel Pin) can really make for a bad day. but very easy to fix do a search for KDP and you will come up with many good thread's about it.



I would go for some more pump work. A hand full of guy's one had already posted here are really getting some good fuel out of the VE's. I would talk to GREENLEAF or BGILBERT about that. or you could p-pump it :-laf





alos not to get off the subject but Bill how's the 66 working for ya?

Working good so far. Should be on a load dyno this weekend in St. Louis so we'll see how good the clutch holds with a load . With the wastegate hooked up I was hitting 36-38psi, unhooked I've seen 42psi, and more fuel to go. I hope before the dyno I can see if I can get more timing out of it and give it some more fuel . One these days I'll come across a IC that holds air.
