How hard do you think the start will be with the lower compression. Also I heard that reducing the compression increases MPG's, do you know if thats true.
lol, ok, that makes a little more sense. my first thought... HOLY CRAP, a 24/26 hybrid wasn't enough so he had to do a 24/27 hybrid! it would probably still work wouldn't it?
how do we lower our compression? h/g spacers?
I do know that I drive torque, while listening to my friends prattle on about horsepower.

I'm wondering if that K27 cold side would bolt up to the K24......Quote from: Rabbit on Roids on May 27, 2009, 10:54:48 pmhow do we lower our compression? h/g spacers? Nope, got to keep the flat part of the pistons close to the flat part of the head so the squish and quench do their thing: cooler pistons & better turbulence in the swirl chambers.The bigger 1.9 swirl chambers drop the compression from 23:1 to 19:1. The bigger ports are a bonus.The lowest CR from off the shelf parts is a 1.9 head on a 1.5 block (1.6TD block with appropriate 1.5 parts in it) which yields a CR of: 17.68:1 I wonder how bad the combustion process would get hozed up if the flame pockets in the pistons were machined deeper.
not quite sure...but now, knowing that i can build a 1.5 with 17.5 compression, im going to...should be able to run quite a bit more boost with lower compression right?and it wont be nearly as rattley either. or is my thinking not right?and will it still start on normal glow plugs?or would this engine be addicted to starting fluid?
30* is about all the colder it ever gets here, so i doubt it will be much of a problem.and also, i located some 1mm O/S pistons from a fellow dubber, 50 miles from me no less.and they are german mahles no less...now i just have to talk him out of them.
