I'm still working on my motor project... So much that I probably won't torque the heads back on until X-mas
work is killing my VW hobby)
BUT, I was wondering will all this talk of 103s.... Is there any thing I can do to my motor (stock 914 d-jet 2.0) that will give a good bang for buck ratio that won't require cracking the case or machining? Ratio rockers? Slip in oversize cylindars? MSI? Jacobs bug pack?
I'd like to have a relatively stable reliable engine when done.
I assume you are going to keep the FI? (Please do!) If so, 96mm P&C's are a start (about 5hp). Set your CR to 8:1 or 8.5:1(about 5hp). If your car is a 75-76, junk the heat exchanger/muffler for a 73-74 set up with SSI exchangers and good muffler(about 5 hp). MSD ignition is nice too. Then take it to a good dyno shop to tune the FI. When done, you Will actually feel the difference!!! Cost about $1000 if you shop around and don't forget to put in a new clutch/pressure plate while the engine is out.

76 914 2.0L (with the above mods)
so, ummmm...... which ones are the GOOD ONES?? 96s that is. i see in a european motorworks ad (is that the same as "eurorace"?)
kit includes JE forged or Keith black hypereutectic cast pistons, light pins and spiral locks.
$325 1.8 K/B 96 piston lit
$349 2.0 96 piston kit
$550 2.0 JE 96 piston kit
are the forged the ones to get?
AA automotive products has
94 flattop piston $189*
95 racing piston $229*
96 for 2.0 $329*
96 for 1.8 $309*
94 std for 2.0 $229*
* = lightweight piston with slipper skirt design
are these things any good? would the 95 racing piston give too high a C/R for a street engine? how bout the flat top 94s?
i'm eventually gonna rebuild one of my 1.7 &2.0 bus cores with a 71 stroke, but i like all these choices of piston size but don't know which one to choose. this engine will be in a street bug, i'm shooting around 100 or more HP and trying to keep it cheap too.
