Crazy idea talking with friends this morning

[TerryBPP]

How about a VW bug with a subaru in it? Cheap tub, light, and sleepy.

Jack,
I like the way you think....

Apparently, the factory had a bad run of crankshafts. The crankshafts were machined just slightly out of spec, and as a result the main center thrust bearing on the crankshaft wears prematurely. When this happens, the crankshaft will move or "walk" every time the clutch pedal is depressed. Some people have complained of difficulty in getting the car into gear (manual transmissions) and the diagnosis has been the same: a "walking" crankshaft. The crank can walk so much that it pushes the crank sprocket and the trigger plate forward and causing the trigger plate to come in contact with the crank sensor, thus breaking it. When broken, car won't run because ECU needs signal from crank sensor to know when to fire coil and run injectors!

Mostly a 1995+ 2nd generation motor problem. Something the factory is VERY aware of. Get a 1st generation 6-bolt to reduce the likelihood of that problem. Stronger bottom end too.

KTL do you have any information of this Porsche 911 Mitsubishi 4G63...i know there is one around

[KTL]

Nope. Only saw a picture once when a topic like this came up. Might have been an eBay post.

I only know a little about my 911 and a little about my Laser. Put the two together and I haven't a clue.

There are a couple ways of looking at it though- purism and potentialism.

The more the cars are changed around, the more rare and valuable the stock-configurations will be, but the historical signifigance and community numbers to maintain public interest in the model will be lost.

Example: gradually the Model A community all decide that lowering the chassis, installing rollcages, and putting 295's on is the norm. Result is the 10 people in the world that didn't hack them apart have cars worth millions(to those that will buy them), but nobody really cares, and the history is lost.
On the other hand, F# history because the Model A chassis is super lightweight and has track potential. The factory itself has changed/bastardized configurations endlessly. What's holding up progress?

I stand upgraded. Thanks,

If the engine crankshaft is in the center of the clutch (like a 911) one could assume the sump is all below that making the CG potentially lower than a 911 engine .
