  1. Hey guys been a while but lots done this month and it's running. So here is the down pipe getting welded

    I've had a few issues, it was falling on her face under boost and struggling for rpm so new plugs gapped down to .032 and some plug grease on the ends solved that. It still has a hesitation under boost but it isn't tuned yet. Ill get a few more pics and videos up with final price and hp once everything is figured out.
     
  2. Well its time for an update, I have been working some bugs out over the last little while.
    First was tuning, 06 pickups did not have room in the computer for a custom operating system so I now need to go to the wreckers and pick up a used accelerator pedal, tac module, and wire, then upload an 05 computer program and cos.
    second was boost. I wasn't seeing near the boost I was hoping for, but after talking to a few people I changed some springs around in the factory gm 6.5 waste gate actuator and that solved the problem. 6 psi in first, 9psi in second, 12psi in 3rd and 4th, 7psi in 5th with the cruise on at highway speeds when its called for. turbo is building boost around 1800rpm and is completely spooled by 2400, it starts dropping off again around 4800.
    third (completely related to 2) I am now however running out of fuel on the stock injectors when the engine is working good, but I have a set of 56 pound injectors just need to order a set of ev1 plug ends.
    So im still driving this thing everyday which is a little sketchy since it has no tune but the afr readings are pretty good. My fuel millage is still decent if I behave, last tank of premium got over 600 kms on a tank. According to my iphone dyno, I have seen an average jump in horsepower from 220rwhp to 250rwhp, a gain of 30 horse at the wheels untuned. My 1/4 mile has dropped from average 17.3 to 16.7 but I havent been able to really push it yet. I cleaned up the exhaust this weekend so it is now 3' turbo back through a magnaflow muffler, it sounds good and you can hear a nice turbo whistle at lower end. I will get some better pics of what it looks like now and see about a video tomorrow, I am very pleased with it now and cant wait to be properly tuned. its going to be awesome.

    knightracer_08 shared very nice pics. I think all the pictures are looks like saying something. It's very nice to see engine our other parts.

    Thats a huge build! Very cool seeing it done to a standard cab short box too. I've usually see it on extended cabs

    Holy hell! That's a cool build! Might think about increasing exhaust size though. 3.5" would be pretty optimum for your build. 3" is pretty stock and restrictive with the tubo.
