TC 78 on a 346
TC 78 on a 346 I plan to eventually buy a Turbonetics TC78 once I get my "turbo debacle" sorted out. I believe I have found the shop I will buy from, now I just need to pick the turbine housing size.
It will be a stock LS1 346 short block through a 4L80e and a 9" rear end. I was thinking .96 A/R for now, with the option to buy a larger housing if/when I redo the stock motor and go for more cubes. My hot side plumbing has an undivided T4 flange on it, and I wasn't sure at what point they go to divided housings.
They told me that the could upgrade me to the larger "T" compressor housing for about $40, and that it was only slightly larger than the "TC" (I want to say I was told about 1/2" in overall diameter). Sound right? My hot side was originally built to accommodate a Master Power T70 while keeping the radiator in the stock position (which I've already planned to go to a vertical for other reasons) so if it's much larger than the MPT70, it might be too close to my crank pulley.
Thoughts?

The smaller housing will spool slightly faster but will fall over sooner at the top end due to backpressure.
