I am in process of purchasing my 5th 914. I have not owned one for @ 10 years and miss it vary much. Can anyone tell me what the differance between a 1.8L and a 2.0. What is required to make the 1.8 into a 2.0 All the cars I have owned were 1.7s or 1.8s My first one was a 1971 my dad purchased in 1972 and sold it 17 years ago with 40 k on it. My second car was a 1973 and I drove it into the ground fallowed by a 1974 then a 1975 . I sold the last two when I got married. Big mastake getting married and selling my cars.

A 2L engine = 71mm stroke, 94mm cylinders, and 2L heads
A 1.8L engine = 66mm stroke, 93mm cylinder, and 1.8L heads You can add a 2L crank, pistons, and cylinders to make a 1.8 into a 2.0. At that point you might as well consider 96mm cylinders and maybe even more stroke. I agree with Joe. Buy a 2L car if that is what you want. Building engines isn't cheap. |

Can anyone tell me what the difference between a 1.8L and a 2.0. A little less than 200 cc's (IMG:style_emoticons/default/biggrin.gif) crank 66 vs. 71 rods length pistons and cylinders 93 vs. 94 heads spark plug location size 15-20 hp give or take What is required to make the 1.8 into a 2.0 new crank, rods, pistons, cylinders, heads, tin, possibly heat exchangers, efi if you want djet with the 2 ltr. maybe more maybe less (IMG:style_emoticons/default/beerchug.gif) |

You can make your 1.8 L a 2.0 L (1971cc) by changing the crank, rods, and P&C's
you can run your heads and the rest. Although the 2.0 heads are a better design and will give you a little more power. |

He has a good idea, stay away from dealing with rebuilding 2.0 heads, they are a discontinued rebuild only availabilty now,, a pain.. |

That is all I am referring too as just a warning of what could happen... (IMG:style_emoticons/default/smile.gif) |

(IMG:style_emoticons/default/smile.gif) buying replacements of most items on these cars of ours is not cheap. but rebuilding heads from len was running 600 this week + parts. most of the opinions i have read on here about head work state that you need to have a shop that has a clue as to the type 4 heads before you allow them to do anything. |

(IMG:style_emoticons/default/biggrin.gif) another option is to keep all the 1.8 internals and 1.8 heads and use larger pistons and cylinders, the "norm" big bore kit yeilds a 1911cc...this will be a short stroke motor, it gives up a little bit of torque compared to a "real" 2.0, but it is still a very enjoyable engine... |
