You won't make that kind of power on that turbo with those injectors.

Megasquirt aem anything that's tuneable.

I got the injectors for 10 bucks wants going to pass em up

Those injectors are good for ~220whp max

What size you think I need?

I wouldn't be too pessimistic just yet. They may not be New Hotness, but those injectors aren't too far off the mark. I'll have to see if I can dig up some old dyno logs, but when I was doing ~210 WHP on the Greddified 92, I seem to recall that the 440cc injectors I had on there still had a fair bit of headroom left.

Presupposing that you've already put money into cleaning and flow testing them, I'd stick with the injectors that you have and see how they do. Just keep an eyeball on the injector duty cycle as you dial up the boost, and if they start wanting to go above 90%, that'll be your cue to upgrade.

Also, know that the stock connecting rods and 5 speed transmission won't be too happy at 250 WHP, so unless you plan to spend a bunch of money there, don't get to married to specific random numbers.

I ain't to set on those numbers Just kinda what I'm aiming for. If the motor pops, that's fine just time for more parts. I know some people running about 300 HP on stock internals But you never know
