Doritofu Posted July 1, 2015 Share Posted July 1, 2015 So I've done my research and figured out that when building an FJ20, the best thing to do for low power is to get a set of S4 Rx-7 turbo injectors, but as is the case when building a car, they showed up and something's wrong. these pictures should illustrate: stock: new: and the hole that they have to fit into: so as you can see, the gap in the intake manifold is 9.8mm diameter, but the width of my new injectors is 10mm. Theres a counterbored hole above the 9.8mm one that the O-ring sits in, so what im thinking... Should it be fine for me to drill out the lower part of the hole to 10mm as long as i leave the top part the same so that the O-ring still fits? Cheers.

R3spct Posted July 1, 2015 Share Posted July 1, 2015 Yup, i had same issue fitting these to a GTIR fuel rail, but i think i had to go to 11mm to get the o ring to have a nice fit Quote Link to comment Share on other sites More sharing options...

Now i can drill them all out and get this thing one step closer to running. Quote Link to comment Share on other sites More sharing options...
0R10N Posted July 1, 2015 Share Posted July 1, 2015 Jesus christ, that is a large signature file. Have you taken into account how you will convert from hosetail to top feed injector type? Quote Link to comment Share on other sites More sharing options...
Doritofu Posted July 1, 2015 Author Share Posted July 1, 2015 Large sig because is imporant, haha, but yeah, I'll probably get rid of it soon anyway. I was just planning on removing the entire injector w/ hosetail and then just putting a new piece of hose onto the fuel rail and clamping them to the tops of the rx-7 injectors. I've heard that it's a decent enough way to do it. Do you see any problems with that idea? Quote Link to comment Share on other sites More sharing options...
