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.

I've had way to much of my real job to deal with so far this week. Tonight the trailer comes to haul the car to the dyno for final fabrication and tuneing. Last night, got the puke tank installed, interior put back togather and cleaned up, and routed most of the vac lines for the rising rate FPR, blow off valve, and to the turbo for the boost controler. Need a few "T" and 90 degree fittings I couldn't get from the hardware store at 11pm. So, alot of work done, but not alot of photo progress. I'm going to try to get to the car by 1-2 today, switch into mad mechanic mode, call in a little help, and try to get things as done as they need to be by 9-10pm tonight. I'll shoot photos and load them over the weekend.

The thermostat/sandwich plate adaptor is a mocal, purchased from BAT in Florida. It mounts between the oil filter and case. When using the good quality OEM filters, the filter does not extend below the engine mounting bar, so no worries there on a lowered car. The combination oil cooler/thermostatically controlled fan came straight out of the summit racing web site. Its a B&M part # 70298 in the cooling section of the catalog, if you have one. It comes with the cooler, fan, and thermostat to control it all. Just add key switched power and ground, and you're in business. No mounting hardware was included, you have to come up with that on your own.
