We put a RD logics turbo 2 pipe on it and its in a HPI R40 that was owned by a professional racer, I got 2 of these motors NIB for $160 each from a close friend whos ran gas for years...he said they were bad fast.
The 5 port modified one or it was a 3 port is just shy of power to the NS12 so it has about 1.45 or more HP. Regardless this is a great motor to use for the track and is on par with the OS .12 TZ and other mid range engines.
Trying to live every day like its the last....
I wouldnt care. I still run one with the Palmaris BRB P/S set. They work far better than most other engines in our climate. I would just be happy if I could find a new one for sale. For some reason, every 11mm crankshaft on the market just disappeared after the NS12 came out.
