Rear mounted turbo?

Actually, the quoted passage disagrees with what you said:
Because everyone who is making decent power here runs a speed-density system, not the AFM.
BTW I wasnt alluding to you when I made that "*****" and "crap" statement.
The point is, unless someone tries this setup (near the cat, not near the muffler), speculating on its performance is of no consequence.

JT and 18psi, how tough do you think it is for Subaru to switch the position of the intake and exhaust ports on the cylinder head.........not very. With that they could have drastically shortened exhaust manifolding and also run a front mounted intercooler very easily.
Even with all those advantages they still didnt do it. I think its beyond me and you to speculate why. I'll take Corky's approach and say that Subaru knows a thing or two more about turbocharging than any of us here. Hence nothing wrong in copying their layout and giving it a shot.
Speculating that one layout or the other is "*****" and "crap" without trying it, IMO, is stupid. But hey, no harm in following convention for the majority of us.

as far as "dont hate it till you try it" here's a nice little link for you\/
he tried to convince us rear mounting is superior in ever aspect. so i got tired of it and banned him.
I did love his comments like (from his tuning video on youtube) "ran autotune on spark map last night, so that's worked out" 3:00
watch at the end in "boost" slowest 15psi ive ever seen, in matters of spool and speed of car.

pipefather, im really not trying to start anything or argue with you, my opinion is that rear mounted turbo on miata's is kinda dumb, lets just agree to disagree and everything's cool...peace

lol WOW.....that looks like complete *** not to mention slower than a snail. hahaha id love to read some of the threads with this guy defending that setup

Me neither, but did you even read what I said? The dumbass in that video mounted the turbo ALL THE WAY in the back of the car, and anyone who thinks their spark map has "autotune" shouldn't be allowed within 3 feet of an ECU. He likely made another hundred thousand compromises in system design, and here we are taking that as the benchmark for an alternative layout.
I, on the other hand, said it might not be such a bad idea to mount it in place of the cat, thus making the header length somewhat equal to that of the Subaru.
And the whole point why Subaru was brought up, was as an example of how they considered this to be not such a bad idea, I mean if it was, they would have changed the layout by now. Even the WRC cars have the turbo in the same exact place, look it up.
Again I'm not saying this is optimal, but it could be a good solution for someone who is on a really tight budget and doesnt want to spend money on a manifold and downpipe.

I got a rear turbo! Powered by Bean burrito's and unsweet tea!
Guys anything can be done if you like the battle. But there are so many used parts that you can bolt up easy. WHY!
I tried to make my own A/C bracket on my 300 hp CJ-7. 2 weeks later I just spent 275 dollars bought a new compressor and bracket and was done in 2 hrs. A/C was alot nicer than playing with it.

i've done quite a bit of research on this and will be doing a remote system, but it's going to actually be a front mount system. two smallish turbos and a seperate oil cooling system mounted ratrod style.
i know this sounds thrown together, but i actually put a lot of thought and research as well as doing some drawings and before all's said and done i'll probably have my bro draw it up in autocad.
to those who doubt

Autocad FTW, but drawing something that complex would be beyond me. Designing a 3'd drawing of a house was cake(it was pretty cool, could do a digital walk through and stuff, I miss cad.) Your brother must have skillz that killz

JW here...what happened to this kurt rohmer guy. I cant see any of his posts in this thread ( https://www.miataturbo.net/forum/sho...+Rohmer&page=4 )
...did he get like hardcore banned or something?

Cliff's notes:
255 lph had come loose in the tank, used a new nut and bolt to secure the stock brass base- blazes through 7k in first 3 gears. major hairy on top of 4th and 5th.
time to go to the dyno for tuning and pulls.
still popping a major silicone coupler around 17psi... 1 out of every 3 times. fabricating a couple of bolt holders to keep the pipes together and taking the strain off of the silicone coupler. P.I.T.A.!!! but it should hold to 21 psi (my goal).
