lol, i dunno about the fuel thing, i haven’t hooked my wire up yet. mine runs richer than hell as it is though, i need an aftermarket FPR…
anything’s possibly with a big enough budget, lol. i have heard of the NEO being a totally different motor wiring wise compared to the normal rb25. it can be done though. the biggest thing on the 20/25 was how the intake ran over the engine. on the rb20, the BOV would hit the hood if mounted with the r-32 x-member. but yeah, it should be possible though.
