I've read "a lot" about the type 4, but still have some questions. My father worked on these engines when they where new, so he's teaching me how. I'm looking to build an type 4 engine with these parameters:
1.8l case 96mm cylinders 78mm crank Some questions: 1. If the stroke of the crank is increased, how does this affect the cylinders? Are the cylinders shimmed to the new stroke? Does someone make "78mm" cylinders"? Are the pistons/rods shorter/longer to make up the difference? 2. Should I look for a 2.0l case? From what I've read the cylinders fit in the 1.8L case. Are there any other benefits to the 2.0L case? 3. If I decide on 103mm cylinders, where should I send the case? (It will need to be machined for the crank anyway. Unless I decide to take a grinder to it (IMG:style_emoticons/default/biggrin.gif) ) 4. There are a lot of 'kits' to buy. Should I go with a kit or buy the parts separately? One advantage is kits come with gaskets, etc... I have more questions, but this will get me started. Thanks |
