Hi All

Im building a special engine for my G1Cab, its a 1.8 PL 16V, that have been bored up to 83mm, and got pistons and pistonrods from a 9A corrado engine, and a Crankshaft from 2E, at the end i also got camshafts from a ABF..

So in the end it should be a fast 2.1L 16v

Im in the process of assamble everyting, and i have now mounted pistons, pistonrods, and crankschaft.. but when a insert the oil/ignition drive rod, then when i try to rotate the engine, number one pistonrod hits the gearwheel on the oil/ignition drive rod

How do i fix this? can i grind something of the diameter from the gearwheel, og e couple of mm of the inside of the gearwheel?

I really hope that you can help me here..

Kind Regards

Welcome Back

Sounds like a nice setup you've planned

But I''ve some trouble understanding what exactly the pistonrod No.1 hits. What do you mean by "the gearwheel on the oil/ignition drive rod"? And, to exclude any misunderstandings, pistonrod No.1 is the one next to the toothbelt, the most left one if you're standing in front of your car or the most right one if you're sitting inside your car.

Hi Chris, and thanks :) ( i have to ask here no one else knows anything but you guys :) )

Hmm ok then its cylinder 4, check this picture:

and i wrote wrong, its called a sprocket ;) and its the end og the pistonrod that hits it... :(

Hi Morten,

That's what I expected, the cylinder you were talking about is usualy called the fourth (4.) cylinder

Well, as far as I know, the only problem should be the block itself, which needs to be grinded here and there for the crankshaft to rotate freely. I've never heard of problems with the oilpump. But, just a hint: the 9A shaft driving the oilpump als well as the 9A oilpump itself have different part numbers than those of the PL/KR. There might be a difference. I guess it's easier to start with a complete 9A block, this way I had no problems.

As far as I know, there are a few persons here who made a similar conversion. But I don't know wether they are capable of taking part at an english discussion or not. Give this thread one or two days.

Hmm ok, ill hold my breath, and hope for some answers.. :)

Ok, dann mal in deutsch, vielleicht kann jemand helfen:

Morten baut einen neuen Motor, bestehend aus einem auf 83.00mm aufgebohrten PL Block, 83.00mm 9A Kolben + Pleul und einer 2E Kurbelwelle. Jedoch stößt sein 4. Pleul beim durchdrehen an das Zahnrad der Zwischenwelle. Kennt jemand das Problem und kann etwas dazu sagen? Am Hochblock vom 2E kann es nciht liegen, da die 2E Kurbelwelle identisch mit der vom 9A ist und Pleul sowie Kolben ebenfalls vom 9A kommen.



Gruß
Chris

Hier gehts um einen ähnlichen Fall:
forum/showthread.php?t=280396&highlight=kurbelwelle

Allerdings sind wohl trotz des gleichen Hubs der 2.0 Motoren nicht alle Kurbelwellen gleich. 2E und 9A haben wohl verschiedene Teilenummern, vielleicht liegts schon daran?

Welche der folgenden Motoren sind Hochblöcke?
9A, ABF, 3A(audi) 053105101H
2E 053105101K

ABF und 2E sind Hochblöcke, 9A und 3A nicht.

a Danish guy knew the answer, you have to grind 5mm off the sprocket, and you have to do it on the inside of the sprocket.. now you all know :)

OK, but I advise you to do it in a mashine shop. Remember the high rotation speed, an unbalanced mass as a result of wrong chipping might destroy the shaft.
