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.

We've got a group buy going on our headers if you're interested. 304 stainless steel primaries, 1/2" thick steel flanges and steel collectors, whole header is ceramic coated.

Only thing is we can't guarantee that the header will fit, seeing as how it's a motor swap, and that motor was never offered in that body style. i'm sure you're already aware of that.. finding ANYTHING to work in swap vehicles is usually an interesting task. the 2RZ is a much better motor choice than the 3.slow though.
