How to port and polish a turbo exhaust housing

I'll fill this in later. The "book" I typed in this field before didn't save. Come back later if you want to read more about the theories behind porting and polishing.

Porting an eBay 20g turbocharger
The price of this turbo will make it a popular purchase, so I figured I'd air out some tech about ways to improve it. This thing is not for everybody. I wouldn't feel comfortable bolting it on my car the way it comes out of the box. I could complain about its flaws except that so far absolutely none of them have been a deal-breaker for me. To me it's like an empty canvas. I promise to eat those words if it happens, and share my poop. Usually I can easily correct these flaws myself and so can you. BUT! If this thing turns out to perform well with what I do to it... It could easily be a cheap, quick ticket to an 11-second car. Something you could do with a free running 1g, a hacksaw, and about $500 worth of fuel upgrades. Yeah, that would be ridiculous, and I'm bolting it onto a well-modified car... But that being possible speaks volumes for what a DSM can really do. This is no big deal to me. I'd rather guinea pig my car for you in HD so you guys can decide whether or not you'd spend your money on this. Really it's an experiment because this isn't my daily-driver, and it contributes to building a better Colt. Tools I used involve: Scratch awl Milwaukee model ???? 1/4" straight-shaft electric DIY grinder Cone and ball-shaped double-cut burs 180 grit high-speed flap wheel Dremel with a flex-shaft and a tiny 320-grit flap wheel a zip tie 10mm combination wrench tiny flat-blade screwdriver (00) for the e-clip on the wastegate compressed air

2g GSX How-To: Attempting turbo swap with WTF ending
Okay. Now I've seen it all. There's an old adage that states "if you want something done right, you have to do it yourself". Well, this video both confirms and debunks that theory. A lot of that depends on each person's definition of "done right". You can't do things by-the-book with aftermarket hardware. Sheldon bought this car with a pretty full mod list and it ran great at the time, but by the time we got it to the track, we couldn't beat a 16-second pass. Despite the laundry list of troubleshooting we both attempted to do through tuning and testing, we couldn't determine why it was around 4 seconds slower than it should be running. I started having doubts that a "ported T-28" was what was on the car, and there's no easy way to tell them apart without removing it so we opted to install a 14b... since plenty of people easily run 13's with them. Stick around for the plot twist.





How to Rebuild a Turbo - Part 1 of 2
Rebuilding a td05h 16g turbo. This process can be applied to many journal bearing turbochargers. :) It definitely comes in handy to know how to do this when you are in this type of hobby. 4/25/12: Small explanation on the balancing of the rotating assembly since I get so many comments regarding it. This particular turbocharger, td05h, has its rotating assembly components balanced separately. This means each individual part (compressor wheel, turbine wheel/shaft) gets balanced separately. This allows for easy interchangeability of parts in case they need replacing. This is why I am able to install a td05 20g wheel on this turbo without having to balance the entire rotating assembly. THIS IS NOT THE CASE FOR ALL turboS OUT THERE. You need to research whether your specific turbo (if it's not td05h) was balanced as an assembly or "component balanced" like I explained above. I hope this information helps. Good luck in your projects.

4g63 Balance Shaft Elimination - bearing modification
This is the first part of a two part series about balance shaft elimination on 4g series engines. This video details the bearings, the other video will cover the front case modifications. I've already got a low-def video of the front case mods, and I plan to re-shoot that one in HD when I'm in the assembly phase. It's linked in the video. The balance shafts are designed to cancel out harmonic vibrations caused by combustion and the spinning rotating assembly. They may offer a greater degree of comfort to the driver and passengers, but with that comfort comes a price. Often, when a 4g63 timing belt gives up, it's because the balance shaft belt breaks or comes loose and takes the timing belt out with it. When that happens, it can total your pistons, valves, damage the crankshaft, wrist pins, timing belt tensioner and crank angle sensor. Basically, it can total your motor. The balance shafts also have a combined weigh over 10 lbs and both are driven off the timing belt making them additional and heavy rotating mass. If you've got a lightweight flywheel but still have balance shafts, you have your priorities mixed up. So here's what you do with the bearings. It's easy. You can do this at home. You CAN do it with the motor in the car, BUT DON'T. You must enjoy punishment to do this like that. The end result will slightly increase your oil pressure, but usually not enough to cause concern unless you have a full-circumference bearing turbo, ball bearing turbo--with your oil feed coming off the oil filter housing. The head feed would be better in that case because it's regulated at 15 PSI.

Installing a T-28 turbo on a 98 Eclipse GSX
This is an easy install. Everything is in the same location as on the factory turbo, and bolts right on. Those of you who have never installed or haven't upgraded a turbo yet might find this video more useful than those who have. Torque specs from the factory service manual are listed for what's most important. It's imperative that new turbo bolts are used with new FACTORY turbo washers. They're a specially designed spring washer, and are single-use. Use of other kinds of washers may cause bolts to break or vibrate loose. This turbo was on the car prior to this installation, but it received a port job to match the burly EVO III manifold. We installed a head-feed turbo oil feed line rather than use the factory hard lines connected to the oil filter housing. Some argue that the oil pressure from the filter housing can be harmful to the life of the turbo, but IMO, that only applies to turbos with full circumference bearing center sections. Either way, the Stainless Steel line is cool. I'll post the part number for the plug needed to block off the old line location.

Installing an eBay 20g
I'm reviewing an ebay 20g TD05 internally-gated turbocharger. You've seen me open it, assess it, and port it. Now I'm going to install it and see how it fits on my car. Its dimensions are close enough to a Mitsubishi turbo that it fits well, but it didn't play nice with my aftermarket stuff as the video illustrates. You'll see what I mean... The wastegate actuator nipple aims straight toward the compressor housing, and I don't like it. I fixed it with a pair of pliers and an allen wrench at 5:55 in a way that's far less likely to break it. The flanges and bolt centers lined up fine and without any issues, though others have claimed to have had them with this turbo. The compressor cover is an obvious giveaway regarding identifying this turbo. It does not wear the cast-in designation TD05H that the Mitsubishi turbos do, but for $228, what do you expect? If you chose to go this route, just manage your expectations. Be aware that it might not bolt up perfectly to your particular car, and be willing to fix what isn't perfect.

Tuning 102 - Idle Tuning
Setting base timing, fuel pressure and ISC motor using DSMlink v2. Getting the idle speed and baseline settings correct is crucial to achieving a good tune once fuel and timing adjustments begin. If these values aren't satisfied or have failed in operation at idle, there is little chance of achieving a consistent tune once the throttle comes into play. Like in Tuning 101, none of this is relevant unless you've fixed ALL of your Boost leaks.
