I can understand running sans oil for a quarter mile. Not so much 30,000 miles.
To be fair, I have never used one of these comp turbos. Just seems like the sort of thing that everyone, from F1 to heavy equipment manufacturers and OTR truckers to the OEMs would be using if there was really something to it.
I will admit, however, that the temptation to build something like this and then attempt to run through a CA smog check with it is tempting. I wonder if there would be space to cut a hole under the stock air filter box and bring a charge pipe up into it...

dont laugh your *** off - yet
has anyone played with a rear mount turbo on a miata ?
sure its easy enough to put one in the engine bay
but what about one under the trunk, running low boost and no intercooler, purely letting the length of the pipe work function as an intercooler, max 0.5 bar or so
I think it would be simpler and not sure of downsides at this stage as its just an idea - biggest headache will be the oil feed and return issues - but theres comp turbos grease filled turbo to make that problem go away,
I am guessing it will be cheaper to do a rear mount for sure
whats the obvious thing I am missing ?

NEW SETUP, NEW LAYOUT, NEW MOTOR, OLD TURBO!!!
my 1990 Mazda Miata with a rear mounted GT2256 Variable Vane turbo, 460cc redtop injectors, LC-1 wideband, and Megasquirt Plug and Play ECU, this has been "Built" the right way. should be good to 21psi once i get the coil over plugs installed.

no the original turbo is a GARRETT GT2256variable vane from a mercedes..
the new turbo is a GT2260Variable vane from a Sprinter Van.
the oil pump is from Turbo Werx
the setup was good enough for 18 psi and i leaned out the number two piston on my third motor. looks like playdo.
everyone is encouraged to contact NUTMEG MIATA CLUB to question members concerning my car. it is known.. that's all that i will say right now.

If you were to do a rear turbo there are only two ways to go either drop the cash on a comp turbo that is oil less and people have had good sucess with or use a regular oil cooled turbo and use a scavange pump with an oil tank and a cooler all mounted under the car. You can mount the tank in the trunk. The tank method works well and has been proven to work but requires lots of fittings and lines the comp turbo is the way to go but they are around 3k just for the turbo you can buy a really nice pre-made kit for a miata for that cost.

If I were to do one, I'd keep my cat on the stock exhaust, tune horribly, and have the cat break-up into the turbo on the dyno after running my mouth online...
...oh wait.
...oh wait.

There's that minivet guy I've seen on CR that has his turbo rear mounted, but I think that was more or so because lack of room.
