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.

Here come some pics- being only slightly more computer literate that a rock, I didn't realize I had a re-size function availible with what was already on the laptop. Oh well, live and learn. Maybe this is a good advertisement for SDS. So easy I can do it!

So far as progress, spent the afternoon finishing up on cleaning and lubing up the door locks and internal door mechanisms. Had one of the plastic odd shaped thingies give way on the driver door, so it seemed a good time to go thru both doors. Got the ITB "hats" placed, and have the intercooler perched on some boxes to find a good location. Tomorrow is a big road day for me, but wednesday should be a soft day at the real job, my wife is out of town that PM, so I should be able to work on the car, eat pizza, and toss back a few beers, all with great success, so expect more pics late wed.

I've included some photos of the L and R sides with the ITB hats and intercooler. The perspective of the photo makes the 2" inlet to the hats look like its angled way down and away. In reality, when you figure the drop off the intercooler for the new charge pipes, things should line up pretty well for a dual hump 90 degree elbow, 2 of which are on order.

The boost gauge is from... a subaru. Why I haven't just done the whole subie swap is beyond me- the reason for this gauge is its small size, and its case is rubber, so I can trim the back of the gauge off 1/4 inch or so, and it'll fit the short space avalible between the dash and top of the steering collum, with out overhanging and getting in the way of the steering wheel.
