what injectors size should use for 3.0L M20 heavy mod engine

[Calvin Tan]

I wonder what fuel injectors size should I use for my 3.0L M20 heavy mod engine. I'm currently using Accel 19lbs fuel injectors. Nothing wrong, just thinking of upgrading... 21lbs or 24lbs???

You should be feeding enough, but for a little headroom the 21.5lbs from an M52 (I know you'd be buying new anyways, just using an example)would work nicely.

Yeah, 21.5 pounders should do the trick. AA recommends them for their ~240whp 2.9 M50 so they should be plenty for your motor.

I have some 21.5# injectors for sale if interested 50k miles - $75, sorry for the plug.

Thank you guys for the input and offers. I'm planning to buy a set of brand new Accel performance fuel injector either 21lbs or 24lbs. But can't make up my mine which one to go for.... :(

Brand new is always best in my book. If I were you, I'd buy the 24# injectors right off the bat in the event that you may do a little extra tweaking down the road that may want some extra fuel. 24# injectors not working very hard is better than 21# injectors working much harder as long as you have the proper software. If I remember, you can tune your car to whichever you get so you shouldn't have a problem.
