Getting close to finishing the engine for an ‘86 turbo. He’s also a 914 owner (IMG:style_emoticons/default/beerchug.gif)
Soon it will be on the test stand and once it’s running, we will convert to electronic ignition and coil on plug. I can’t remember the compression ratio but I recall it being a bit more than stock. The real hero of the build is the cam and turbo upgrade. Cams are turbo SC and the turbo is highly modified and builds boost 500-800 rpm’s earlier than stock. We’ve built two similar engines and they are a hoot. Hopefully it will make the owner smile. Attached thumbnail(s)

Yes!!! One of my favorite builds on here was Chappy’s turbo. I’ve always wanted to put a 3.0 turbo in a 914, forget all that intercooler piping

With 180,000 miles on the engine, it was leaking oil from every interface/hose, blowing smoke out the exhaust, and had an intermittent miss on one cylinder. Turns out the Beru spark plug caps all cracked and one was making intermittent contact causing the miss. Didn't help that I cross threaded #2 spark plug. (IMG:style_emoticons/default/dry.gif) Mark also rebuilt the transmission. For items needing replaced, Mark said 'All the consumables were consumed'. Here's the progress thread of the rebuild on Pelican: 1986 930 Engine R&R Attached image(s)

The shop that rebuilt the turbo said it was one of the worst they had seen. Maybe Jerry will post pics of the old parts.

@mepstein
The new heat exchangers connect the exhaust of the passenger side bank to the turbo from the front of the engine whereas the OEM exhaust crossed over at the rear of the engine. Will this help the breathing of the turbo? You mentioned the builder of the new heat exchangers but I don't recall who it was. They look fantastic.   |

I’m pretty sure they are B&B’s. Reasonably priced and work well. We’ve used them on a different turbo build and got good results.
