I was considering doing a head job and changing the pistons and cylinders on my 1.8 liter while I have it out. (IMG:http://www.914world.com/bbs2/html/emoticons/huh.gif)
What are the oem cylinders? 70 mm? I have seen people peddling "94mm" I am not looking at doing dual carbs right now. (IMG:http://www.914world.com/bbs2/html/emoticons/screwy.gif) Can I go larger and still use the stock L jetronic Fuel Injection system that I have kept well maintained over the years? |

I am looking into 96mm's w/ stock heads. Again I am trying to avoid converting from oem EFI to carbs.
Can I stay stock fuel w/ 96's and upping the valves? What adjustments if any would have to be done to EFI and timing to accomodate this increase? I was told that going to 96mm's I would have to watch the compression? Do they mean stroke> What is stock stroke w/ the 1.8 93mm's 70mm's? Therefore what do I need w/ the 96's? I was also trying to avoid cracking the case so I am not interested in doing a cam right now. I really appreciate the input, (IMG:http://www.914world.com/bbs2/html/emoticons/pray.gif) Thanks Pete (IMG:http://www.914world.com/bbs2/html/emoticons/beer.gif) Attached image(s) |
