Oh yeah it is.. This is why I've always done Top mounts...
Its not using a standard To4S compressor housing however, and I also plan on offering the low mount with a GT35R turbine wheel mated to a billet 56/57mm compressor..
That with a .82 turbine housing would be a nice autoX/street combo.
I am also in the middle of putting the turbo farther forward, more near the motor mount. I am trying to avoiding a terrible turbo flange entrance angle. It adds a lot of lag in my experience.
For those that aren't aware that is always a downside, unless you are running a tube chassis car or sandrail...

well all the usual forum ego flagellation aside, it's not for me to tell you how to do your thing, so I will only suggest that for a low mount setup you may want to reevaluate your general philosophy about turbocharging a rotary engine and also reconsider some of the more recent discussions we've had on the subject lately. The suggestion is based on many comments I have observed being made over the years both here and on RX7Club.
I don't deny that the top mount has it's purpose and function. However, trying to more or less duplicate it in a low mount is maybe not the way you would really want to do it IMO. Based on my own extensive experience in autocross I think your relative comment is perhaps not entirely an accurate assessment. Further, I would suggest that my own experience tells me will work the bestl for an autocross application directly translates into what most people would be absolutely floored over and amazed to have in a street application.
for your consideration with no disrespect intended ...

Cold plugs usually foul faster with street use. We do however prefer to use the NGK " race " plugs which last considerably longer. It really depends on how cold you go, and how you drive.. If one is driving like a grandma a lot and only do small pulls on the street you can get away with hotter plugs.
I did just make a long writeup but it was just deleted, and I don't feel like retyping.
Get yourself a Vbox and you can determine your shift points based on acceleration rates..

I am in the middle of building 3 different low mount turbo systems; one is even for an S2 car. Unfortunately we are very behind as I've been out of town for the modified magazine shoot out, and I am the only one here who fabricates.
It looks like the cold side turbo outlet pipe is welded directly onto the turbo from this angle. Also is there going to be a hard line from the engine side of the turbo to get at the water inlet/outlet?
