    Turbo Kit ??

    I think that any of the main brand S/C’s out there are going to make you happy. The trick is, to find a kit that includes the hardware to add additional fuel to make it go. Not many stock ECM’s can deal with a two or three bar MAP sensor. So, unless the kit has some way to figure out the...

    Turbo Kit ??

    Hey thanks, It will probably take a S/C to satisfy your “need for speed”, with the Duramax diesel in the next stall. I had the Vortech on my 95, B4 the turbo’s. It was awesome. There must be some of those kits out there somewhere. If you find one, be sure it includes the injector...

    Turbo Kit ??

    I would doubt that there is anything currently made for that engine intake style. The Banks, twin turbo’s are a bolt on system for a small block chev, but first you would have to go through the engine, getting ready for it. It also requires a “4150 intake manifold with port injection. They...

    Guys guys look :p

    If you are doing a dyno pull in 1st gear on a 4L60e, I think you have to divide the results by the gear ratio, or 3.06 :1 The dyno's are expecting a pull in 3rd gear or 1 ro 1 ratio. If you did pull in 2nd gear, divide by 1.65 They also generally track torque along with hp. 5200...

    Trans problem after new exshaust

    Sounds like just driving it, may be doing more damage. As mentioned earlier, damaged wires, either burnt, or cut, on the main control cable that plugs in on the passenger side of the trans. I would go straight to a tranny shop and have it checked. They have a tester, that can read the...

    NIB Trans Controller "TCU" on Ebay

    The TCU is a separate computer that controls the 4L60e or 4L80e trans. It comes with a program for your laptop to set the parameters of the trans. You answer the questions in the setup as far as gear ratios, tire size, etc and then set the speeds you want each gear to shift at and so on...

    NIB Trans Controller "TCU" on Ebay

    Anyone looking for a TCU (transmission control unit)? This control runs circles around any shift kit on the market. I spotted a (new in box) unit on ebay. Search under “TCI TCU” It’s the complete kit. I have been using these controllers for years. It can do either the 4L60e or...

    shift kit??

    There is a unused circuit that would do the same thing if you could find it. It is what became the “Tow Haul” or “performance” circuit, in different models. It is a black wire in the transmission harness that if grounded, takes the trans pressure up to the preset amount. I have...

    U joints

    The U-Joints without the grease fittings are considered to be stronger, since they don’t have the cross drilled holes for the grease. They are solid……… :)

    Bad Ass 2dr Yuk

    Hey thanks, It is kind of a side project. It is the daily driver and tow truck, so it’s kind of a part time thing. Eventually I plan to see if it can keep up with the Camaro, but that is a moving target, because the Camaro is ready to break into the 10’s. My next phase for the Tahoe is...

    Bad Ass 2dr Yuk

    I’m pretty sure I used a deep pan from Summit Racing. It adds about one quart. I was mostly interested in having a drain plug. I have tried several electric exhaust cutout’s. The QTP (quicktime) lasted less than one day, and is built like a toy. The DMH is pretty good, but it has two...

    That's awsome It sounds like he is running a stall speed TC around 4500 rpm's :)

    Keep it forever???

    Just past 50,000 miles this past year, at this rate, 12 yrs B4 I hit 100K. Plus, after rolling with the “twins” , GM would have to start selling a 2dr with twin turbo’s to peek my interest. Then again, a new one, would probably look like a jelly bean anyways……… I’ll just stick with what I...

    Maybe you guys are rushing things a bit. The Mayan Calendar for the end of the world shows December 21, 2112 as the magic day. Personally I would make a stand at home rather than taking a vehicle that gets 8 miles to the gallon for a limited drive to nowhere. :)

    pic of my hid fogs

    I'm all for HID's, but I think there should be an effort to use a lens to keep the law enforcement people happy. Otherwise, you will more than likely spend some extra money on repair citations. Many states are starting to crack down on non OEM HID's. Just my .02

    heat now?

    Sounds like the thermostat is not closing all the way.

    11 Codes! SES Light was blown? Ran fine yesterday.

    OK, so let’s review the chain of events. Your truck was running great, you decided to have some exhaust work done and immediately after the exhaust work is completed, it runs like crap. The codes are showing O2 sensor problems. We are guessing that an Arc Welder was hooked to the...

    11 Codes! SES Light was blown? Ran fine yesterday.

    The question is, did they use a "arc welder", to do the work on your exhaust? Arc welders have been known to do damage to electronic equipment on vehicles. Especially if the ground cable is in the wrong place and not well connected..........

    What thermostat to run??

    There seem to be a lot of guys running lower temp stats here. I’m not sure what the reason would be in the winter, but I would like to point out that oil does not lubricate as well at lower temperatures. I once bought a new chev pickup truck that came from the factory with a piece of...

    Any one running oil breathers?

    There is always a certain amount of air/vapor, that gets past the rings, from combustion. It is directly proportionate to the combustion chamber pressures and the wear factor of the rings and cylinder walls. In a normally aspirated engine in good condition, the vapors are normally handled...

    front diff wires cut need pinout

    I just went out and checked my Tahoe. It's a 95 and it's manual for engaging the 4 wheel, but the plug and front actuator, looks the same. Looking at your picture, if the upper left pin were pin #1 and the upper right, Pin #2, the middle, # 3 and lower left #4 and lower right #5...

    front diff wires cut need pinout

    The generic diagrams from Haynes do not show the “pin outs”. What you could do is check out the wires with a meter to see what does what in what switch position and then take a +12 and ground clip lead and touch the pins in the actuator. They obviously change polarity to reverse direction...

    Any one running oil breathers?

    You should not remove the PCV for any reason. If you have enough "blow by" that it does not keep up, you can add breathers. The PCV will keep the crank case fumes at a minimum while the engine is at an idle. Forced induction engines often have positive crank case perssure while under...

    Have you had...

    Most parts stores will have the brake tool. It has a curve in it that makes it much easier to use then a flat bladed screw driver. Jack the wheel off the gound enough to turn, then tighten up the brakes until the shoes start to drag. Then turn the other way until is stops dragging, while...
