My 1994 (yes not a Tacoma) 3.0 pickup is getting a 1998 2RZ-FE engine along with a 1987 R151F turbo transmission and dual transfercases. I was reading up about problems in the past with factory manifolds cracking so I am considering getting some headers for it. I was looking at Summit Racing and I noticed that the Thorley headers for this (and the 3RZ) application are not Tri-Y, but rather 4 into 1. So which headers would you guys recommend? My truck is pretty heavy sitting on 37" MTR's so I want to try to get the most power and fuel economy from the engine possible. I noticed the OBX headers on Ebay, and I don't want any Pacesetter's! I already have them on my other truck.
