When I built my truck, I didn't know that some trucks came with alloy front pipes that point forward. I also didn't know that these were compatible with the FE-DOHC block. When I was in the USA I spotted these pipes while looking around the junk yards there, found a mint one, and brought it home to NZ. I thought I'd share some pictures here of the stock pipe, my modified stock pipe, and my new slightly modified alloy front pipe. The alloy pipe is not only better flowing, but also significantly lighter, and factory made to work in a RWD application, in summary, perfect! I recommend the alloy pipe to any RWD conversion including mx5s and rx7s and anything else that needs the coolant coming off the front, not facing backwards.
Pics here soon!
