| These are going onto our latest project car. Here are pics comparing the 1820 RR to the TDO5H-16G turbo. These are NOT the same turbos that come in the 300zx PE1820 kit, those have a smaller turbine. It is hard to tell, but the 1820RR's turbine is slightly bigger and has 11 blades vs. 12 blades on the TDO5 turbine. Compressor wheel is larger, compressor HOUSING is huge. This turbo in its internally wastegated version has put down over 350 AWHP on a WRX. We will be selling these with tubular manifolds, but likely only if we install them. We will sell to other shops, though. I do not have the time to walk people through the custom work that is required to make these fit.
