2,8?
I have looked at a movie on google and i heard a man said he had drilled the engine. Someone her who has tried it? It make sense if you use 1,9 pistons.

Well, I dont know the language they are speaking, but you couldn't use 1.9 TDI pistons, and I didn't know of a 1.9 IDI engine. I would also be suprised that there is enough material in the block to bore it oversize enough to get 2.8 liters. The max overbore pistion thats sold is 1mm, which ends up increasing the size to about 2.5 liter.

I'm skeptical too... there was a VW 1.9 IDI engine made, not sold in US but available in Canada. However, it had a taller block than the 1.5/1.6 family, and a longer stroke as a result. There was never a D24 made with a taller block, so I don't know how you'd make a 1.9 piston work. Sounds iffy.
Looks cool, wish someone knew what they were saying...

I know what they are saying and it is in a very funny dialect also I think the guy had a few drinks before making the video
 , Anyway he claims 260 hp and that is a little bit to much I think... normal output with the mods he claims is about 200... he sais bigger pump head bigger turbo bigger nozzles etc... but it looks very nicely done! He is running on cooking oil...

I dont now thats why i asking. I have 94 1,9 td with mechanical pump. I have heard about a 2,8 in bigger vw lt. i understand what he says in the movie and he says 2,8. But i think hes turbo is little to get 260 horsepower.

Guess it would depend on the pin height of the piston, but still you have the problem of the material needed to cut the block that big.
Stock bore is 76.5mm I did some research and found the 1.9 IDI AAZ engine is 79.5mm bore x 95.5mm stroke. Even if the piston did have the correct pin height, the stock 86.4mm stroke with a 79.5mm bore would get you 2573cc engine, so not quite 2.6 liters. You would be talking a 3mm overbore! Thats .117" cut into the block! Thats alot of material.. For argument sake, the math is cylinder dispacement equals: bore x bore x stroke (in mm) x .0031416 / 4 Multiply that result by 6 cylinders and you have the engine size is cc. 79.5 x 79.5 x 86.4 x .0031416 = 1715.53225 answer / 4 = 428.88306 428.88306 x 6 = 2573.29838cc Jason

The block would have to be taller, as George said. The 1.9 was a different block compaired to the 1.6 family, which is what our engine is based on. The stroke difference is almost 10mm! I think he had a few extra drinks that day!
