It is possible to bore an 88mm 17 block to the 93mm 19 dimension, but it is not a very good idea as the cylinder walls get real thin and lose their roundness when they heat up. I had a -68 17S Olympia A coupe a long time ago that some previous owner had bored to 93mm and I remember that the oil cons...

Of course we need a kalender 2019 !

There are also the usual oversizes 88,5mm and 89mm, or you could use std 88,8mm pistons from a C26NE, but you need the connecting rods too as the compression height is different.

It should be possible to bore it to 88mm and use std 17S pistons.

The carbureted exhaust manifolds have heat ports that lead exhaust gases in the intake manifold for heating, while there are no such things in the fuel injection exhaust manifolds. 004 (2).JPG Picture of the heat ports in the intake manifold. It is possible to use a fuel injection exhaust manifold w...

Yes,normally when there is fuel in the carb, but if the car stands a few days and the fuel has evaporated from the float chamber, you can choke as much as you want until the fuel pump fills the float chamber. The culprit is our modern gasoline which is oxygenated and formulated differently than the ...

The fuel vaporizes from the carb if the car stands unused for a longer time so it takes some cranking to fill the float chamber again. One effective fix is an electric fuel pump that fills the float chamber instantly when you turn the key.

I don't quite understand what you mean, but the jetting numbers are for both barrels when it is a two barrel carb. And there are two different carbs a DGV has different jets than a DCD. There are also separate jetting tables for single or dual carbs.

nur mal so theoretisch...

passt ein ab fgst-nr GSE-Getriebe an einen ab fgst-nr. 2,5S Motor?

also rein mechanisch, nach dem Tacho muss ich eh schauen, da defekt...

Yes, it will fit.

Hast Du nicht einen 2,0er Kopf ? Dann passt ein 2,4er Krümmer nicht,weil die Kanäle anders liegen. That is not true, the exhaust ports are the same in all cylinder heads, it doesn't matter if it is a 15N or a C24NE. The front pipe flange bolt pattern is different on the C24NE exhaust manifold compa...

Einige Motoren brauchen sogar einen gewissen Gegendruck, um ihre Leistung zu bringen. Yes, if we talk about two stroke engines. But a four stroke engine doesn't need back pressure, the less there is of it the better. The right diameter of the exhaust system on the other hand is very important, if t...

Choose Polyurethane instead of Teflon, Teflon is too hard.
