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 |

Something to think about: Because of the expansion and contraction of the exhaust manifold you have designed I think you should put in some Stainless Steel bellows so the manifold does not crack.
My 2-liter with turbo at 7 lbs. of boost made a lot of power and the exhaust glowed red after hard running. This was back in 79 or 1980 or so. I had hydraulic valve lifters in the car and the only thing wrong with my engine was the parts supplier did not sell me harden lifters. Every few hundred miles the vales would get out of adjustment and when I pulled down my engine the lifters looked like mushrooms. Bob B |

Bob B That design isnt to be taken to seriously... it was a group project, not everything was my idea. Thanks for the advice. |
