I see a lot of people use the DSM 450 injectors, but are they really necessary? Couldn't I use something off of one of the lessor DSM's or maybe a prelude and still be fine? It would be nice to hear some experience from anyone using other injectors. If anyone knows the rough whp/boost limits of these injectors that would be very helpful. I am looking for options for my 2000 Si that I hope to get up to 260whp on a stock engine.
Thanks for the help

 

you better get 450's if you're looking to make over 250 whp, i wouldn't use anything smaller for over 200 whp cheaper solution? they're only 50 bucks, have you priced namebrand 450cc injectors

Here are the reasons I was looking for other options:
possible free injectors
easier install (i was hoping i could just pop in the prelude ones)

 

get the free ones, sell them
sell your stock ones, and you'll have enough money for the dsm 450s. i got mine for $40 at dsmtrader

 

FC rx7 injectors (2nd gen) had 440's on the NA... earlier years had low IC late (88.5+) had high ID... but i doubt the injector clips are the same...

just know there are always 7's in the yards...

You can get 450's for $50 and they take about a half hour to install and they're good for some very decent HP. Why complicate the easiest part of a turbo kit?

 

Agreed, I paid $60 shipped and they are worth every penny.

 

Ford redtops 310cc. With a little dremeling on the end and 2 O rings stacked they fit right in.

 

Bizzar can you take a picture of one of those done and ready to fit in and post it? I'm curious. I can get brand new 440/42lbs Ford injectors dirt cheap.
