wow so much hate!

This turbo setup is fairly common on the v8's, in particular the ls1/2... (mainly US cars) and the ford boss motor's for the xr8's (bit the xr8's mount near the subframes/just under dash area, and yes it still does work, given maybe a slight increase in lag and the extra weight of the additional length of piping.

Generally speaking, for a Honda or Import to go this way there is no major benefit apart from a more 'sealth' setup. A downside that people have with this setup is the cast iron housings cracking when going thru puddles or rain due to the uneven heat temperatures that the housings get from the water splashes etc. A solution to this has been to create 'shields'.

There are a few cars out here, i have seen a couple fords here in melbourne that have been running these setups for a while (twin turbo - small turbos like gt28's) and are running in the 10- low 11s brackets, so it must work!

Once again, the only reason these are rear mounted is for either
1. Sealth Setups
2. No room up front
3. Possible better weight distribution

For a honda to go this setup, i see no reason as there is plenty of room up front, and will most likely be more efficient. For a ls1/2... they respond very well to small boost whichever way the turbo is mounted. The closest honda to get a 'rear mount' setup is the nsx, but that's cos the motors up the back!

Ideally mount the turbo up front, if that cant be done, mount around the gearbox or a rwd car, if still no room then try up back as a last resort if you really still want to turbo!
