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 |

I have done a low boost turbo set up before. I did this 100% by myself with lots of research on a -6 3.0.. I ran 6 psi of boost using a 3.2 intake and megasquirt.. I was not a megasquirt expert but it worked fantastic for me.. I did blow that engine up when the wastegate signal line melted as it was too close to the exhaust. I then built a 3.2 short stroke out of it and went with a divided housing turbo and dual wastegates and bumped it to 9 psi with 8:1 compression ratio.. It was extremely reliable but the learning curve was expensive.. The type 4 project will be fun for you and for us to read about.. Enjoy the process but be prepared for set backs.
And just because I can I will share my 3.2 ss picture you will notice a few things changed along the way with exhaust and the intercooler.. |
