Are there any 550 side feed injectors from other manufacturers (i.e. MKIV Supra TT injectors) that will bolt in place of the factory 370cc injectors on an SR20det? I searched but didnt find a real answer from anyone.

Im in the middle of getting my SR swap running, and now im considering an upgraded T25 based turbo/550's/AFC2 combination.......but im wondering if theres an alternative to $$ new injectors.

Any help appreciated

i dont know if the injectors would work, if u want cheap injectors that are larger i would go for the z32 tt injectos, they r bigger then the stock ka and will wokr, the q45 injectors <2001 are the same as the ka injectors so dont bother with them

just to clear up, the 300zx tt injectors are the purple ones (same as sr) and they only came on models 93+ (iirc). I don't know any other manufacturer who shares the same injectors with nissan/infinity.

The mkiv injectors are not the same. The best bet is to get a fuel rail and regular top feed 550 or 50lb inj. There is really no other options other then buying expensive sr20 injectors from heavy throttle or something.

if the link doesn't work just search in the advanced 240 thingy for "850cc injectors" you will see something about rx-7 injectors......
