Does anybody know if nissan and toyota side feeds are intercangable? I have a 4age 20V that uses side feed injectors. IF I cannot get them cheap, I'm going to make my own rail and run top feed injectors.

 

They are not interchangeable, the only ones that I found that fit the 20v is from a 3sgte or 2jzgte

 

Diameter of the injector body and plugs are different.

They are not interchangeable unless your VERY good at fabbing. I.E. - This is fuel, so don't just give it a try unless you know what your doing.

 

I got a set of new sard 800cc injectors for my 20v for around $400. I also planned on doing a custom fuel rail and converting to a top feed system, the main reason I didn't go through with it is that you will have to relocate the throttle mechanism and linkages because of the quad throttle setup. Another thing is you have to do is get a sleeve machined so that you can install the top feed injectors in the stock injector bungs to get the same angle and depth. In the end converting would probably cost around $400 anyway.
