hello,
I am an automotive engineering student at the University of Windsor. I am trying to somehow incorporate the restoration of my 914 into my education somehow. After talking to many of my professors a few of them are suggesting I try and turbo the original 1.8l type-4 came in the car. I have the entire case completely apart, down to the crank, and am at the stage where I'm getting ready to start blueprinting this engine. However, it seems that turbo type-4's are not very common, and I do not seem to understand why. I am ready to take on the challenge, however, I would love some advice (combinations, etc.). I am thinking that I will keep stock crank and rods, and get some JE forged pistons (not sure of size yet). Was also thinking I port the stock heads. However, beyond that, i have planned anything. cheers, Blake |

Member ejm on here built a 1.8 liter turbo four as well. IIRC, he used the turbo off a VW 1.8T, likely for the same reasons McMark did. He also ran CIS from (I think) an Audi 5-cylinder motor, using the 5th line for extra enrichment?
Member Evill Ed built a 1.7 turbo quite a long time ago. When the 1.7 started having problems I believe he bumped it up to a 1911cc. I don't remember the engine management, but he did have water/methanol injection to help with temps. Another member here owns that car, and may have made improvements since. Good ol' SammyG from Pelican built a 2.0 turbo. He used a draw-through carb setup. He admitted it wasn't optimal, but it did work. I think I remember that the car and engine were sold separately, and the turbo setup didn't go with either. Finally: "Everybody knows you can't turbocharge a 914!" That is a quote from an old "european car" issue, which was widely derided at the time by those of us who had seen (or a few who had built!) the above cars. It's become a catch-phrase in many on-line 914 circles. --DD |
