Aftermarket injectors/stock primary rail. Will they fit?
Hey guys,
Just as the thread header states. I cant use an aftermarket primary rail for my top feed injectors i bought due to modification of intake manifold for hood clearance into 3rd gen.. Question is, Can I use aftermarket side feed injectors in the factory primary rail without major hassle?

Not aware of any aftermarket sidefeeds. You might be able to get away with installing the FD 850 secondaries but the primary rail will need to be modified. The stock 20B sidefeeds are not the same as the FD primaries.
Another solution may be to just run the stock primary rail and injectors, then just run even larger secondaries. It really depends on you HP goal.

Nippondenso 850cc Injectors
I saw these but Im worried about them fitting the stock rail. Im running 1680cc secondaries, I do not want to create that large of a disparity between primary and secondary injectors, Im running a microtech and heard that they suck when theres a big difference between primary and secondary sizes when it comes to transitioning on your fuel map.. This car is going to get regular use so that is a factor.. Power goals are 500hp range base, and 600hp range for high boost. Running a Borg Warner S475 so I can move the air..

Those are OEM FD 850's, not aftermarket, see my first post.
You have the option of sending your stock sidefeeds out to RC to be enlarged to 850cc.
The transition point on the Microtech can be tuned regardless of injector size. Problem is that many people are not in matrix mode for some reason.
