gst injectors, ??? about making them fit

[baxsom]

Ok so i am buying the parts i need for a megasquirt project
and decided to go with the GST 450cc injectors
mainly because i got them for next to nothing
the MS will handle the low resistance so that part is covered
but the next question is how do i make them fit into the rail
i found some threads where it says to use the 420a O rings
but that just doesnt seem to want to work
do I need to just push harder
also these are the blue top injectors and there is no O ring on the bottom
the stock ones will not go over the cap
so do i just leave the bottom of the injectors O ringless

Honestly... sell those and get the correct ones. I too was offered larger injectors but for a 4g63 rail for next to nothing but turned it down because it is just too much of a hassle to deal with. People say they fit fine, but I just dont see it.

eBay them and buy the ones that fit into the 420a rail. seriously.

i am beginning to believe that it is true

i finally got them to go into the 420a rail but i am not sure about the bottoms
i just dont see it

i found these online

does anyone know if they are direct fit ]

55 each for 50lb injectors seems like a pretty good deal

I have never heard of them
BUT
I like the price, now Iam thinking of getting them but it dosen't say if there for the 420a??
also
Hahn and acell have injectors for the 420a also

i know i got my 270cc's from hahn
and i am not sure what accel part# matches to 50lb injectors
they are just so expensive
i was linked to the racetronix from the 2gnt site so i am hoping that they fit
they do have what looks to be the same size O rings
i just wish i could find dimensions on the website

i know for a fact hahns fit perfectly
but if i can save a hundred bucks on injectors by going with the racetronix then so be it

here is a link to the dimensions

so if anyone just happens to know the oem 235cc dimensions and they are close to those above please let me know

The best rule of thumb is you get what you pay for.
I did some searching for some 50lbers or less for you, didnt turn up much on any dsm boards I got to, but I did find Delphi 550cc injectors on ebay for $255 shipped...

i have been scammed too many times on ebay as of late

a couple of people on 2gnt.com have put in injectors from the racetronix site and so far have not had any problems
each of those people even used the low imp ones and put 420a O rings
but i got one of my stock injectors out of the toolbox and the measurements come pretty close to the high imp injectors offered by them so i believe that they will fit
best part is
they are new, and flow matched


i have pretty much given up trying to save money on this car
every time i get a used part off of ebay or try to save a buck here or there
something went wrong and it cost more to fix it
