I probably should have joined 914world and started posting earlier but I have been reading and learning ALOT about these cars already from whats posted in other threads. For that, I thank you guys. I have some catching up to do. Heres my story.
I picked up my first 914 a few months ago as a project car that could eventually serve as a track car or weekend toy. Out of the many different types of cars that would make cool projects, I ended up with the 914 in my crosshairs after I discovered that not only they were mid engine but v8 swaps where not uncommon. Other factors include I had never came across one in the wild, which makes them rare to me. I also like the idea of following in my fathers footsteps with a mid engine european car. He had a Lotus Europa in is 20's. Jumping back the v8 idea though, the added weight of a more powerful drivetrain is at the center of the car, meaning there is a minimal increase in the rotational moment of inertia: the car should retain it's handling characteristics better than a v8 swap in a comparable sized car with a forward mounted engine. After investigating several craigslist ads that turned out to have missing titles, a friend pointed me towards a local Porsche shop that was known for 914's. Bingo. More 914's than I expected. A few short conversations led to a cheap car that needed some work and was up for grabs. Heres what the '75 2.0l car looked like prior to being yanked out of the weeds. On the trailer headed home Some of my buddies and I broke out a pressure washer and the car looks good for sitting outside for a year or two. The car did not have the original engine or trans installed when purchased. Although, they were included in the sale. Some tinkering around got some of the electronics working off a jump start box Now heres the fun part. A month or two later, I came across a craigslist deal that would add some originality to the project. An 5.3l L83 out of a 2015 silverado with only "15,000" miles for $1200. Would an engine with 15,000 miles still have the assembly grease in between the rocker and top of the valve? (IMG:style_emoticons/default/confused24.gif) For those of you unfamiliar with this engine: It's NOT an LS, its part of the EcoTec Gen V family. The next generation of Chevy v8 that shares some of the architecture with the LS but with direct injection and variable valve timing. Also its an aluminum block which is different from the Gen IV 5.3 truck blocks which were cast iron. Rumor has it that GM is offering a stand alone kit for the gen V engines which, while costly, would simplify the install a lot. Quick specs: Stock 380hp and 416 ft-lbs on e85 fuel. 11.0:1 compression ratio ~400lb dressed. Anyone know how much the original 2.0l engine weighs? At this point I'm sure most of you have thought: "What does the hell hole look like?" The rot is the worst of all the ones I have viewed online. The only saving grace is that after selling the original motor, trans and wheels, I have made back the purchase price of the car and have a few bucks in my pocket. I have some experience in fabrication and plan on being a sheet metal pro by the end of all this. Heres a shot of the floor pans and fire wall area. At this point the car is stripped and ready to be mounted on a rotisserie. Lots of bracing prior to mounting on the rotisserie of course. I have more pics and more details but that should do for now.

@914forme Thanks for the suggestions! I will likely experiment with various versions of stiffening with the new computer and stress analysis (FEA). It will likely be over engineered but it makes me happy. (IMG:style_emoticons/default/piratenanner.gif) Still waiting on the computer to come in.. Lenovo needs to get their act together.
Since the rust extends all the way back to the suspension console and I'm working in the area, I started looking into the raised suspension console option. After some research on the 914 simi trailing arms, I can't convince myself that's the way to go. So.. I'm looking into a 996 suspension swap. The rear has a multi-link setup that looks promising. I'm picking up Boxster front suspension components tomorrow from the junk yard. Basically whats in the following pic, except for the struts and rack/pinion (IMG:style_emoticons/default/idea.gif) Lots of head scratching ahead of me. Bought some of the best suspension books known to man and will use Optimum K suspension software. http://www.optimumg.com/software/optimumkinematics/ |
