what can be done with a 1.7 Options

[i love porsche]

so..in the distant future....i will be rebuilding my 71, 1.7 engine, if all goes as planned i will send it to jake, but what can be done to a 1.7, is it as easy to modify as a 2.0?

should i just get a 2.0 block and send that instead......any ideas/suggestions

im looking for about 150 hp and 150 torque, if possible, nothing crazy, i want to keep it as stock as possible in the sense that i want a t-4 that isnt way much higer than 2.0L

150/150 is hard to achieve w/o going pretty whole hog down the big engine route. Jake can get that out of a 2270 (well, the 150hp bit, anyway). 150ft/lbs of torque is very hard to do w/o a turbo or building the engine up to a 2.4 or thereabouts. Torque basically scales with engine size (normally aspirated). 150 could very probably be done from a 2.0, but you're looking at a revver motor to get there (hottish cam and lots of port work).

To give you a frame of reference, a 2.4 911T engine makes 140/140, more or less. With a stock 914 gearbox, such a engine will light up the tires in the first two gears. Indeed, even anything past 3/4 throttle in first will light up the tires, even w/o slipping the clutch, and you can make gentle starts in second even uphill. 140ft/lbs is a lot of torque for this car.
