I believe i recall reading we cant run 2nd gen injectors in 1st gens but my question is why??

 

Beacause the thread on the body is 14mm X 1.50 thread pitch or somthing like that and the thread on a 1stgen body is 12mm X 1.50 thread pitch. Pop pressures are different also.

But the 7mm tips will interchange.

 

I thought i read some where that the spray angle was different but I could be wrong.

 

IC spray angle is the same as p-pump.
