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.

Mark, only had saturday to get to the car, family ruled for sunday/monday. Hope to get it installed tomorrow night and see how it goes. It looks great, and your customer service has been beyond great.

JPB- you best stay hidden behind that couch lest the mighty 914T smack you down!
(although I really DID think of T1 power, lets see, lighter, alot more been there/done that to fall back on, re-build it monthly when you hit it with the boost... hmmm.. nope)

This brings up an interesting thought- patience or money, which do you have more of? When I turbo'd my ford focus, I bought a kit, it was all there, to the last nut and bolt. Got it done and on the road in one long evening after work. No kidding. This project has taken FOREVER, although I will admit to being sidetracked with auto cross, gutting to the studs and re-doing our master bathroom, (10K in materials and still counting the labor...) golf, family, summer, but still, when it takes a day just to machine up 2 flanges for the exhaust in/out, and all the thinking, ordering, fabricating, re-fitting, re-doing when a better solution presents itself, well, I can really appreciate the one box solutions offered for other cars when it comes to turbos, and actually am quite amazed that the kits offered are as cheep as they are, in the 3-5k range, when I think of all that has gone into this project.

Time for bed. Gotta get an early start to the day to make an early appearance in the garage, for more progress and pics.
