450cc Injectors in RS

[mint567]

Will the 450cc injectors out of a gst/gsx work fine without having to get a new fuel pump on a NT?

So were they your injectors?

I havent had time to check really busy with class. Had a test yesterday in accounting I didnt know about but I think I did good. but I am really guessing it is them or fuel pump/gas tank. I Have had them cleaned and it helped for a little bit and now it is acting back up. I saw a set of 450cc injectors for sale (50$) and was wondering if they would fit. They would be an improvement over the 390cc I beleive that is in the rs/gs. These injectors have 137,xxx miles on them and last time I had the fuel filter changed it was extremely dirty...

you will have you still out the seats for the injectors. i was going the same route and didnt, i would get a varilble fuel regulator to ajust the pressure.

wait. gst/gsx injectors will work in a gs/rs?

[hillbillyboostin]

they wont, i was going to put 4 450cc blue cap injectors in my 97 eclipse gs but the seats was to small to fit the injectors. instead of boring out the seats to fit them, i just bought 24lbs venoms.

they fit just fine... you need the low to high impedence converter though! the seats are the same size... the O-rings that go on the injector tip was probably still in the head and one was still on the tip of the injector thats why it didnt fit, i used 450cc's in my RS for a month without any problems, then i went to 550cc's.
