Injectors?

[Tman1gtsi]

I have some what I think are 660's in my trunk that I got a while ago, and I now have an scm61(that I want to sell or trade) and even though I am not running lean, I don't feel safe with the stock injectors, The question is, why when I put the 660's in, did my car not run at all, lots of sputtering and whatnot, but with the stock ones it runs great, I am looking for someone who I could possibly meet up with to help me find out what size the injectors are and if I could have them flow tested or cleaned. It's just that I am busy lately and am looking for some professional advice (Note: swifty took a look at them and mentioned they almost looked like black 450's, but if they were stock why did they not work)

just lookin for some help
-Thanks 651-491-6370 if anyone could help

Do you even have anything to control larger injectors? That could be why car wouldn't run for crap. Please add more details to your first post; be specific.

No he doesn't. His ECU is thinking it has stock injectors still.

His car is pretty much stock with an SAFC, front mount, 2g mas, 60-1.

The injectors could be bunk or if you dont have them trimed back your just pissing too much fuel in and running ultra rich.

You cant just drop in different injectors and expect them to run. Bigger injectors=more fuel which is why it wouldnt run for crap. You have to compensate to make it run on anything bigger then stock. Also how do you know that you are not running lean on the stock injectors? You will not know this unless you have a wideband or have dyno'd your car and have a wideband print out from that.

A 61 on 450's wow

Raven Works in Maple Grove does injector cleaning and they will tell you what they flowed afterwards as well. I probably wouldn't go that route though unless you absolutely couldn't figure out what size they were.

You'll also need something to control those bigger injectors like everybody said. If you plan on keep modding the car I would go with DSMLink. I would also take it over to Shane at DB Performance and have him tune it so you can get the most out of the car as safely as possible.

Not anymore. As of tonight that motor blew up/ Seized. Don't know what part exactly but it's a goner

you probably burnt a piston

[TsiEagleTalon92]

using a 3/4 socket I could move it one way but not the other. It wasn't easy to move compared to both my 1g's and it stopped dead hard at a certain point before 1 and 4 reached the top

A 61 will max out 450's at what 9 PSI. Running that lean is no good. But you know that now.

ya, bummer, worked for a year, i was only running a 10 pound wastgate spring, never went above 10, but it's my fault --thanks for advice, we already are gettin it all tore apart

I wished we had the necessary tools to take his head off to find something out.
