They do fit. From what I understand that evo 10 injectors are 600cc and you need to repin the injector clips with 93-98 la sc300 clips. Correct me if im wrong

RSX injector:


EVO injector:



It looks to me like the EVO injector is a denso style 11mm inlet, while the RSX is a 14mm. You'd need a custom fuel rail, minimum.

Those are evo x injectors, wasn't he asking about evo 7/8/9? I agree, the newer injectors that come OE are fantastic. There's one OE application injector that can be modified to flow over 1000cc/min.

I use decapped WRX injectors on my MR2 with E85 and they work really well. They idle better than stock.

I understand he asked about evo 7/8/9 but I don't see any problem fitting them if you can fit evo ten injectors on a k20a2

The issue is that the injector bodies are significantly different between the 4B11t EVO X motor and the earlier gen 4G63 EVOs. The later injectors are much closer to the RSX injectors which is why they interchange so easily. Evo 7-9 injectors won't be as easy. They use bosch style clips, and the inlets are smaller than the K20 rail. Granted, rail extrusion isn't exactly expensive so a custom rail might only run $20 worth of materials and half an hour in a drill press, but still..
