What injectors for a 20G?

[91BlackLaser]

My son blew another 14B and now we have a chance to get a brand new polished Mitsu
20G turbo for $500. The car has 510's on it now and I would like to step up the injectors. I was thinking maybe 660's but we are going to stay with the SAFCII. I just need to know what ones I could run safely with the 20G. Would the side mount IC still work if I stay around 14-15psi on the 20G.

definitly upgrade the intercooler. cooler air = happy motor Why dont u just get a 16g instead 550's and a 16g and your set for a while

Get DSMlink and buy 1000's. Be done with injector upgrades for good.

1000's are for race cars not daily driver who are 17. Id say if you are definitly gonna get the 20g get 650's and you will be fine.

Uh, my car is my daily driver and I will be putting 1000's on it and I'm running a smaller turbo that a 20g.

DO IT RIGHT OR DO IT TWICE!

Go with 750cc. I know from experience, and according to a well known formula...most 20g's are heading towards 400hp and need 750cc.

I am running 550's on my car with a 20g at 20psi and getting around 80% IDC.

Boost est is at 17 that drops to 13 and only 31 lb/s min. Thats why you're running an Injector Duty of 80%

After looking at your mods, you REALLY need to increase timing to about 18* peak and lean out the fuel. I'm running an evo3 16 on 550's at 17 psi, pushing 38+ lbs/min with a 22* peak timing curve and no hints of knock whatsoever. Those knock peaks in your log are from too much fuel.

His son doesnt need to run 1,000s@!!!! Thats over kill for him with a 20G.


The biggest feul injector you can run with a afc is around 720ish, and then it becomes a pain in the ass to get the car to idle nice etc

And it sounds like money is a issue so he isnt going to want to buy DSM link, rember then you need to buy a eprom ECU wich is more than a AFC nowa days.



I would do this, AFC 1 or 2 with 680s along with a big16 or a EvO3 16G. You can pick up a nice Big16 for under 500dollers. Its a fast simple setup and you can run on the stock side mount for a good bit until you have cash to get a front mount.
