Well first I will introduce myself as this is my first post. I live in Raleigh, NC and have decided to build up a 914. My dad has lots of experience with Porsches of all types and suggested a 914 as a relatively simple and very fun car. I have been reading this site for a few weeks religously trying to learn everything I can. Im buying a 914 with the intent to swap a 911 motor in it. I am mainly interested in the 3.0 or 3.2 conversion, eventually to turbo. This is where my question comes into play. I have read Iamchappy's thread about turboing his 3.0 motor, and it seems like the 3 liter has no problems accepting boost. However I havent come across anything about turboing a 3.2. Is there any mechanical reason for this, or is it just something no one has documented? The reason I ask is that I am probably going to install the motor in its NA form first, then gather the parts for turbo over time. I think the higher hp of an NA 3.2 would hold me over until its time to turbo, however if turboing 3.2 motors is not ideal, and the 3.0 is a better forced induction motor, I would rather stick with it. My final goal is somewhere around 300hp give or take. At this point I'm thinking that the 3.0 is the better choice because its been turbocharged more often than the 3.2 and therefore I will have more support when problems arrive. Im also fairly sure the 3.0 can give me the power goals I'm looking for relatively easily. But please enlighten me, Im still learning about this 914 thing so I can use any comments you might have. Thanks alot guys!!!

Building the Turbo has a big cool factor, but to build it on a 911 3.0 can get very pricey.
Most 3.0 are close to 25 years old so figure on having to rebuild the motor which gets pricey, than all the Turbo stuff you need to fabricate..... more $$$ If you do it right you will eaisly spend 10k - 12k. If you are looking for lots of power and grunt just drop a stock 3.6 motor into the 914.... lots of power and reliability, and will cost you less in the long run. Also Big Cool Factor (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) If you still want to turbo a 3.0 find the 3.0 that has the lower compression pistons I believe the lower compression motors are 8:1, Turbo applications are better with Lower compression |
