Which motor for future turbo?, my first post. Options

[sgray944t]

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!!!

The C2 (mine is a 91) and C4 didn't start until late '89, they are 3.6 liters and are popular swaps into early 911s...the wiring issue has been resolved with a few companies making kits...the biggest pisser of a 3.6 if want to turbo it is the high compression as delivered from the factory, it is in the 11:1 range...they do have twin-plugs right from the factory so that is a positive (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) The 3.6 motors from the 993 would be nice, that is when they started using hydralic lifters so no more valve adjustments, that is a good thing.....

i missed a 'late' between "in the" and "80s". (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

Up until 89 they still used the 930. Strongest of them all pre-existing the 964.

The 993 and 964 use the same block (964). Only difference is the 993 has air injection into the exhaust, later got varioram and variocam. Turbocharge that and WOAH you'll need new undies. Benefit of those 2 is that they did make a turbo 964, and did make a turbo 993 (equipment already exists).

Fun with the 964 and 993 include: Once the air injectors on a 993 get clogged you get to have a lot of fun not passing smog with a check engine light and a new top end. Or when the drive belt for the twin distributors goes bad. Or when the speed reference sensor goes bad (wont run right). Or the cold-air intake sensor goes awry. Oh wait, that last one's only on 996s and boxsters.
