I have a 95 Nissan 240sx SE with the KA24DE motor. I have found a awesome affordable mod that can be done to the KA. I sent my TB to
http://www.maxbore.com/, and the work was done by Jorge Pugliese. He does some amazing work, he bores the TB to the max then realigns the TPS sensor. He has a lot of experience with Honda TBs so I took a chance with my Nissan TB, but it was worth it I felt gains all throught the power band. I also have a CAI and ported and polished intake mani. But it was a real noticable difference in throttle response and in the over all powerband.
