anybody heard of a V-TEC conversion for the 914. KEP could probably come up with an adapter if he doesn't have one already. but, will a front drive motor work with a rear drive tranny? does the crankshaft spin in the same direction? anyone hear of any other front drive engine conversions? my 914 deserves more power than i can afford to get out of my type 4 motor. for the cost of nickies and upright cooling and head work, etc. i could have a turbo vtec setup.

First, my little rant about the gearbox was sarcasm, for those who didn't get it. Flipping the R&P causes no problems, because the 914 runs a 901 with the R&P flipped itself.
As for reversing the spin direction of the engine, it's possible, but there's a good chance it won't work. First you'll need to get some backwards running VTEC cams made up. Good luck on that. I suspect most cam places will look at you like you have three heads when you ask for it. Second, most modern engines have offset wrist pins to reduce the thrust loading on one wall of the cylinder while the crank and rod are driving the piston on the upstroke. This only works one way. You'd need to reverse the pistons in the bores, at least, to get this to work while the crank is rotating in the opposite direction. There's also a good chance the cam drive won't work when spun backwards, either. There are some engines (primarily Italian) with toothed belt cam drives that will skip teeth if you turn the engine over backwards BY HAND, let alone actually drive it that way. |
