I was going to let Mike stand by his statement, because I wager that julie COULD disassemble a turbo, because if it hadn't been for the siezed exhaust housing bolts requiring an oxyacetalyne torch to remove, a monkey could do it. But my turbo is an early T3 off a Lebaron, NOT one of those tiny, pansy-ass mitsubishi turbos. This one actually has potential. The "revised intake" meant an intercooler, which is why the small Mitsu can make the same power, as the early turbos were non-intercooled, and in fact had the throttle body BEFORE the turbo. Damnedest thing I've ever seen. If your throttle ever stuck open...
Anyway, it had a little bit of shaft play, so I disassembled it in preparation for a rebuild. (A T3 kit off Ebay is like, 60 bucks, and that's with 360 degree thrust bearings) I also did some research on T3/T4 hybrids, and found that really all a T3/T4 is is a T3 exhaust, a T3 center section (which is actually the same, t3 or t4) a T04 backing plate, and a T04 compressor. (you can even port the T3 comp housing and use that, if you want)
So that's what I had planned to do. Plans change. So now I have this turbo and this enormous intercooler, and nothing to put it on. Sad. Sell to you cheap.
I also have the stock exhaust manifold and 02 housing. I was going to practice welding on it, but hey, if you can use it, I throw it in fo free.TurboOmni08 Wrote:One more thing, I heard I can remove my balance shafts to make more power, what are balance shafts (I know what they do, but not how they are physically attached to the engineÔÇÖs internals.) and is this true? IÔÇÖm assuming all 4-bangers have them.
You can probably check out HowThingsWork for a lesson on balance shafts. They're usually connected only by a belt. Most inline 4's have them. Some, of course, do not. The early GM Quad Four is a horrific example. It didn't get balance shafts until 1995, and basically sucked up to that point. It didn't rev, it shook like a diesel, it was awful.
Now, the reason I made the distinction about inline fours, is that all H-4's, a'la Subarus, are naturally balanced, and do not require balance shafts. In fact, all H engines are balanced this way. I-5's normally have a small balance shaft, and I-6s do not need them, as they are naturally balanced as well.
If you were going to remove your balance shaft(s) I would make DAMN sure that your crank, rods, and pistons were both light and perfectly balanced. Otherwise, your bearings are going to pay for your spirited driving. Me, I'd leave it in. You don't have much to gain by removing them. On an N/A car, I'd be more inclined to try and get around them, but on a TC car, I mean shit. There's many easier ways to get the 3HP or less it takes to spin a balance shaft.
(oh, and Scotty, I think I'd sooner remove on of my balls than remove the balance shaft on a QR25. The things got a what, 100mm stroke? Jesus. People are stupid, I don't care what JWT)
