Project Turbo 914 begins..., (yes, I know you can't turbo a 914) Options

Just a little teaser on this winters project. Last winter I dug into this little update:

This winter will be phase 2. This photo will show some of the goodies under the tree, which will soon be under/on the car. The WRX intercooler has one round inlet on the back, and 2 smaller oval outlets under the opposite end tank. These will each exit and attach to some CB performance turbo "hats" for the ITB's that have 2" tubes welded to them. Some silicone elbows, and we're good. The intercooler will mount on braces running across the engine bay to support the intercooler as close to the GT lid as possible. I'll see how it goes, and probably do some yarn tuft testing to see about airflow in and around that lid, but I could always use the SDS computer to switch on either a puller or pusher fan below the intercooler based on boost, if needed. The turbo will mount on a custom flange/adaptor to be built to connect the turbo to the collector of the Kerry Hunter exhaust system. The turbo is a small Garrett VNT. The compressor map looks like a good match for this motor. I'm expecting the VNT turbo to give good low rpm thorttle response. Starting out at 5-6 psi, I'd be happy to see 10 when I'm done, but will tune to run safely on 93 pump gas and see where we end up. Off the back of the transmission, where the factory exhaust hanger mounted, I'll mount a similar hanger to support the turbo and exhaust system. A Tildon differential pump will return the oil to a willing valve cover. Oil will be taken from a "T" at the pressure sending unit on the case. There is a blow off valve to be added to the intercooler, and a mocal thermostat/sandwitch plate adaptor for the oil cooler, which has a thermostat controlled fan. I'll be adding an ignition switched relay for power to the fan and scavenge pump, so both will have power when the key is on. The pump will run continously, the fan when the thermo switch tells it to. Add some pressure side stainless or aluminum tubing from the turbo, thru the back engine tin, into the round inlet on the intercooler and we're done. Except for another trip to the LSE dyno, for some additional tuning. I'll keep posting as progress would warrent.

Final cuts of tubing, and the masked welder in action, adding beads to the aluminum ITB hats, intercooler adaptors, and to the mild steel IC piping. Good to have friends with skills... and now, just needs clamps.

914 Joke of the week. My friend Ron, the welder, goes into town to hunt down a flange to use to mount the turbo to the kerry hunter header collector. He stops at the one muffler shop in town, and runs into a guy who used to be on his fastpitch team, Steve. They catch up a little bit, and Steve asks Ron what he's looking for. Ron says he needs a flange to match a collector, shows him the collector, they find one thats close, just needs the mounting holes hogged out a little. Steve asks whats it for? Ron says "I'm putting a turbo on a 914 Porsche" Steve says "No, really, whats it for?"

Moral of the story: even in a town of 8000 with one muffler shop, a guy with a shaggy beard and no teeth knows you can't turbo a 914...

... what am I thinking?
