I'm a sucker for this stuff I guess. The TT engine build has started! Here it was as just a stripped down short block at my friend's house. It was nasty, rusted so bad you couldn't read anything on it, and flaking badly.  I cleaned it up with a wire wheel and oven cleaner/garden hose at home, brake cleaned it, set it on fire, and painted it. It's not perfect, but it's a lot nicer than it was. I also used a drill hone instead of letting a shop do this one. It's a cheap rebuild for moderately low power goals.  Most fun of all was seeing how badly it needed a rebuild. The rods were bent and twisted fairly badly. And that's just with the stock turbo! I'm glad they didn't see a GT28 or GT35 get used on them.  The crankshaft is in, main seals are changed, all new main bearings. Next step is pistons and rods. I'd like to clean up and re-use the OEM pistons. They're $500ea from the dealer, or around $700 for a set of performance ones. The stock pistons are fine for 500hp, and I didn't see any signs of cracking or much wear. Just dirty. All this work is because I actually just have to do a clutch job. But pulling the clutch involves pulling the motor out of the car, soooo... While I'm here! ![]() |

Is the crank definitely straight? After seeing those rods, I’d be taking a second look! lol

The crank SEEMS to be straight. These 1.8T engines are known to have the stock rods bend, never heard of a crank issue. It's a forged crank that people use at 4x the stock power level

Definitely not as pretty as my eclipse motor, but the block is together. The pistons are clearly re-used, as they're $500ea to replace, or I have to buy 800hp rated ones in the aftermarket for $900. They're factory forged though, and with a little more cleaning, they'll be fine (just gotta get the last nasty carbon buildup off). They had minimal wear with the original skirt coating intact. BC Racing rods, clevite bearings, OEM pistons, deglazed cylinders more than honed, ugly gross and ready to go. Everything moves nicely without any binding. New front and rear main seals as well.   |

I made an absolute mess of my driveway. If anyone has cleaning tips, I'm definitely interested..... I can get it clean, but it's gonna be a LOT of scrubbing with my current method. ANYWAYS... Motor is in, car is very close to driving. Just chasing down where the last few plugs go, battery in, intake manifold on, bumper and wheels on, and it can go on the ground. Today was a nice 14 hours of working on it. Worth it for a neat daily.  Engine swap 2 of 3 for the year; almost complete! Next up, a B6 Audi A4. |

Today the car hit the road. For some dumb reason my new o ring in the coolant line off the head doesn't seal, but that's it. It's a nice smooth motor, and revs out happily.

Very nice! No weird noises hopefully...lol. Every time I do any serious work to my car, I’m always worried I’m going to hear something that I shouldn’t during my test drive...haha

Me too. But it seems ok. Just has that leak. I'll try another o ring

Oh, I never updated this...
The problem was that the coolant pipe temperature sensor housing was cracked. My O ring I tried was fine, the crack just went around it. The next day I took the pipe off and ordered a replacement when I saw how ruined it was internally, and it's been fine since

Yeah, me too hahaha
The car is driving well now that I put a Walbro 450 in, and should be doing about 270-280hp within a couple weeks. Then, when I'm bored of that, I'll be upgrading the turbo. I'm not fully decided on which, but probably a "500hp" K04 hybrid my turbo builder makes. It's a tad bigger than a GT2860r, so I can't see it doing more than 400hp. But I'll try it

I think exhaust restriction is going to be the issue. It's internally gated and designed to be run that way
The intake side seems like it would easily flow the power. Exhaust in curious. It's small, but it's a 9 blade, and it's made by a guy who builds some really neat stuff. He built my friend a custom turbo on the spot, and I think that's just awesome.

Nothing beats the ingenuity of people to build custom stuff. Exhaust restriction from turbo housing or pipe?

From the turbo housing. It's a 52mm, but that could mean anywhere form 250-500hp in theory depending on how well designed
