Here is the bottom of the IHI S/C.

There are two oil compartments for the front bearings/gears and rear bearings each with a feed and return hole. On the mazda, these are fed by thin engine oil, and those guys complain about it leaking out of seals and getting gunked up. Whether I plumb to engine oil or seal off and make an internal bath of S/C oil, I need to figure out what fittings I can shove in here. I didn't grab the lower bracket from the junkyard, but here's what it looks like (the IHI just sits on top)

Here are some up close pictures of the holes:

Can any of you identify what fittings I need to plumb or seal these, and where I might find them?

first thought would be to yank out the brass tubes and see about tapping the case for NPT brass.

...or get somebody to braze some fittings onto those existing nubs.

VEMS + SC + Nitrous
 

So I just go my VEMS PNP from Peep, and it got me thinking again (dangerous).

How about low boost SC + low shot N2O + no intercooler? As I get older complexity of projects is a turn-off. Was thinking of a low shot Wet N2O system instead of the SC initially.

do some research if pre-SC or post-SC injection is better.
that stuff comes out cold and does some "intercooling" on its own. pre might keep the rotors cooler which might help general efficiency? but post would help take the heat out of the charge.

both :evilgrin:

update i guess...
last weekend i finished welding my intake manifold and primed it.
yes, it's got stacks inside, about 10" from stack entrance to valve seat, and the D plenum is big enough to roll a tennis ball through. about 0.75x displacement for plenum volume.

yesterday i was making new brackets to mount my AC condenser and intercooler, so i can then start "laying pipe" (plumbing the IC).
light at the end of the tunnel...

thanks for the update!

Looking good Spencer!

My current plan, in order to avoid yet another custom elbow and vacuum connections, has the supercharger going pretty far back. It fits ok, except it's going right through where the dipstick needs to go. Has anyone had any success bending or otherwise relocating the dipstick?

Thought I might show some progress photos of my S2 SC build, I'm using a Rotrex C30-94, with 100mm pulley, giving about 5-6PSI, No intercooler but a modified oil coole cylinder tyo cool down the Bypassed air which gets heated by the SC then gets diverted to in front of the SC, therefore a potential builup of heat can occur,

The SC ann Nissan Quest alternator are coupled together and both hang off the factory alternator mounting points, the SC has a front and back mounting brackets made out of 6mm Aluminium (tried to find Aluminum here in Oz but couldn't find it) the effect is a rock solid setup

Some shaving of the alternator was needed

With the AFM in place

very clever!

Can you put a turbo in a 1983 Porsche 944
 

Can you do this to a regular 944, and what would it cost?

Yes, I would personally get all 944T factory parts as it would be the simplest method. 944T rods, pistons, crossover, headers, downpipe, exhaust, turbocharger, wastegate, oil drain mount, oil pan, intercooler, pipes, injectors, intake, wireharness, both ecu’s, diverter valve, and a few other components. Getting all that you used will cost you... more than you want but honestly around 3-4k with you doing the work and mostly stock used parts. You also need to consider power goals and if you want low boost like 7psi or want mid around 15-18psi, which would make a difference in cost of what you may want to get. Then you would want to upgrade brakes and suspension as more power shows other weaknesses in the driveline. This is a dangerous slope, hence why the supercharger and the v8 swaps are tempting. I believe the supercharger can be done cheaper and are good for someone wanting insta power but looking for a little more thrill. The v8 can be the same cost or more depending on the level you want to go and quality of the build.
