Hello people.
I'm a noob here, but been around cars for awhile. Recently acquired a 75 914 that is very clean and going to do the Subaru conversion. Car will be used mostly for track events and some odd miles on the street. The question that I had, is how does this car respond to high horsepower? In stock form, the EJ257 will put out 300 at the crank and I'm wondering if it makes sense to tweak it a little more.... I've seen a few conversions done here and read through a ton of threads. Some very helpful info here, but I haven't read anybody's feedback on what the chassis will do if throw 500hp at it? Besides all the supporting mods necessary to handle the power, what will the driving dynamics be?? Maybe it's not worth to do anything except just the engine swap, but since it's going to get a full cage, big brakes and aero, maybe go big (IMG:style_emoticons/default/driving.gif) David |

right now I'm coveting a 2.4
but your going to need a 3.6 to get to 300hp with reliability and pump gas |

but your going to need a 3.6 to get to 300hp with reliability and pump gas Oh yeah... the gas. With a computer listening to the knock sensors, it will advance the spark until "hears" a knock. The higher the octane the more advance you'll get... therefore more power per stroke. One of the differences in the Porsche DME between the 3.2L and 3.6L engines is that the 3.6 computer can retard the spark on individual cylinders, and with dual spark plugs you get a longer burn. More power again. The difference between regular, premium and race gas is noticeable. |
