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.

Good things come to those who wait... well, I've been working on this project way to long to sit back and wait for it to finish itself. If I'm lucky, I get a couple hours a week, one night a week, so its been slow going...

As our novice driving school is this weekend, I have focused the last couple weeks on getting it n/a ready, and doing it RIGHT the first time, rather than slapping it togather and haveing to re-do a bunch of stuff.

So, not alot of turbo ready photos this time around, but getting some of the bits and pieces in place.

A friend of mine, (not dave h, the fearless fabricator) who is a welding genius (how many of you have welded stainless left handed up inside a 2' round tube about as far as you can reach while looking into a mirror to see what you're doing?) is retiring end of this month, and welcomed the small projects I had, such as the turbo to exhaust adaptor, I/C adaptors, and a few other odds and ends. Much cheeper rates that the shop the car was going to, plus I get to have a hand in the project, which will stay much closer to home. The car WILL go to LSE performance for the dyno tune once all systems are up and operating.

Current status pics- one is wireing to the starter, had to extend some lines and of course shrink tube and shield the lines, next is another view of the starter install. The next is the hot start kit. I know, lots of you say you don't need this, and with the mini gear reduction starter I probably don't need it, but with the added heat of the turbo down there, I thought it couldn't hurt, and besides, I have used one for years with no problems. Last is the power to the oil cooler fan, adding a fused connector, and taking power from the jumper to the hot start solinoid.

I've got a few vacuume lines to buttton up, need to attach the rear sway bar again, get it on the ground and give it a bath, and I should be ready to go for the weekend. Not bringing the sticky rubber, why waste it on the newbies, they'll have a thrill ride enough on a short, twisty course in a 30+ yr old car that keeps up with the new stuff, and beats up on a fair number of those newfangled water cooled cars.

I'm expecting, with my work, house projects, welding time, dyno time for this project to extend to mid summer. Bummer.
