You'd think that it wouldn't have taken me 11 years to look at the engine code. I have a '75 2.0. Just assumed the engine was original to the car.
Finally looked tonight and saw the following: So I have a bus engine? (IMG:style_emoticons/default/barf.gif) A 1976-77 2.0 liter Bus, according to the interwebs. Confused because I only see 3 studs on the intakes. If it was a bus engine, shouldn't there be 4 studs? What little I do know: PO had the engine rebuilt by a well-known local shop. Was rebuilt with Hydro lifters Oil dipstick located at the top. Engine pulls to 5500 rpm (I've read that bus engines aren't capable of this) I replace the flywheel with a 914 flywheel when I replaced the clutch. I thought I read where the busses use a different flywheel? What do I have, and is there any chance it was built to Porsche 2.0 specs? Now all I can think of is finding a proper engine.

I see late 2.0 heads. Likely 2.0 motor built in a bus case. Hopefully it doesn't have bus pistons.

Hopefully it doesn't have bus pistons. (IMG:style_emoticons/default/agree.gif) Seen this more than once, low compression bus pistons and hydraulic lifters make for a great update! ^^^ That's sarcasm btw ... (IMG:style_emoticons/default/dry.gif) |

(IMG:style_emoticons/default/dry.gif) I picked up on it. (IMG:style_emoticons/default/dry.gif) Would the engine pull to 5500+ rpms if it had bus pistons? |

Would the engine pull to 5500+ rpms if it had bus pistons? Well, it could. The compression ratio doesn't affect breathing that much; the cam and valves and ports and exhaust and such are really what determine where the engine makes power. Lower compression more or less means less power throughout the RPM range. But frankly, it would be pretty weird for someone to swap over the heads from a 2-liter 914 and do the work to move the dipstick and such while leaving the low-compression Bus pistons in there... --DD |
