I'm in progress of putting my on3 kit back together on my 351w. The on3 kit was for a 302 based motor. I've already noticed a few issue and was already expecting it like. Cold side Cross over pipe, and headers against the strut towers. Got the header issue fixed. Then the charge pipe coming out of the fender to tb. Turbo sits a little higher due to deck height.

Wondering if anyone in here has gotten the 302 kit to work on the 351. If so what all did you do? Do on3 sell single pieces? Thanks! #ad

Your best bet would be to make the pipe yourself . At least you know it will fit not its supposed to fit if you get it from on3 due to variations.

 

x2, and i'll take it a little further... you're better off to build it yourself, or mock it up, and have someone weld it for you if you're not welder. Another comment i'll make is if that's On3's 76mm P trim turbo i'd leave room for an upgrade, a h,c,i 351 will definitely like more turbine than that.

 

Probaby what ill end up doing. I agree with on3 351w version fitment.

Yeah the turbo I have is on the small side. More likely be making the piping my self, and have someone weld it up.

 

I am putting a 302 kit on the 351 in my sn95. So far the headers fit, but I am going to have to extend the crossover and lengthen it to clear the balancer. I am also going to reroute the cold side from passenger side to driver side instead so I don't have to squeeze the piping over the turbo. Of course, I also don't want a huge cowl hood, so that was a factor for me. My engine is sitting back in the K-member one inch as well, so I am blocking off the waste gate tube and moving the waste gate to the center of the crossover. [emoji106]
