help choosing injectors

[4g63turbo84]

Im in the middle of building my motor and om going turbo with it..

But I need help chosen injectors that would be good for my set up.

What about DSM 450cc injectors or even evo 550cc...

What my motor and ecu set up is...

1. 10.5 pistons 2. Manley rods 3. Crank scraper 4. Bc springs and retainers 5. Port and polished head 6. Megasquirt for engine management 7. Hx35 turbo 8. Aeromotive fuel pressure regulator

If you have any questions about what else im using please ask and thanks for any help you can provide!

A wideband do you have one, megasquirt never used that, how are you going to tune the injectors, goals for the car? To get started check out vendors for prices, i saw a thread on what injectors i need for my setup.

He is tuning with Megasquirt. That is how he is going to tune his injectors and his timing and his fuel etc.

Op, if your goal is 350-400whp then you definitely don't want 450's or 550's. I would think minimum you would want would be in the 780 range.

The post above gives you links that will give you an idea of where to go. Its not engraved in stone but it will allow you information to help make your decision.

Now because you are running MS why don't you get something like 880's? You have the ability to adjust for size, so why not get something that will definitely cover your goals, plus allow you room to grow. I ran 1000's with my set-up on MS.

Good to know not familar with megasquirt, pick up some 560s from a evo fairly cheap.

No reason to test the limits of his IDC's. Get in the 780 and up range then you can keep your IDC's in a reasonable range.
