Thank you bones i appreciate all the information I'm shooting for 350-450 hp in my car

Do you have emissions in your area? Do you want the car to be able to pass?

If so, you’re gonna need to swap the PCM, engine wiring harness and engine itself for either an LSJ (found in Redline, also needs its F35 transmission), an LE5 (2.4L found in 06-07 Ion-3) or an 07 L61...

If not you’ll likely wanna go standalone, as I don’t believe you could piggyback tune that much additional airflow...

For your goals, I don’t think you’ll make it on a stock long block. MAYBE if you did head work and big turbo cams, ARP studs and MLS head gasket... your stock clutch also won’t survive that much torque... if you’re planning all the work at once, you’d be much better off to go in the extra $1500 for internals... that’s forged pistons, rods, ARP fasteners everywhere, etc, also known as a full rebuild...

Well my plan is to completely disassemble the engine head and block, new pistons connecting rods, cams valve springs. Basically everything internal is getting replaced wihh better stronger parts. Bigger fuel ingectors and pump. Ngk spark plugs. Head might get ported idk yet. And my transmission is a automatic. So it supposedly can handle more power then the manuals can its the 4 speed tho so I gotta double check on its reliability. If not ima gonna try to get in contact with a aftermarket transmission retailer and see if they can't hook me up with something to improve the Internals of it if not I'm just gonna throw what ever I can into it make it stronger and rebuild it and cross my fingers. And once all that is done and I'm happy with the engine and fuel. Then I'm gonna install the turbo kit from AFI (already talked to them and they said they will provide me with the needed piping for it) which says it can produce 300hp on 8psi of boost on the stock 2.2, so I believe if I up that psi I could shoot for the stars with my built 2.2

Oh, good gravy, you’re building an automatic car? The stock trans will handle some extra power, but nowhere near what you wanna run... you’ll need a built 4T45 to handle 400+whp for certain, if not potentially a 4T65E swap...

it it also complicates the PCM swap because the transmission also needs a controller... if you go with a standalone EMS, you’ll also very likely need a standalone trans controller...

You should lean more toward finding a stock PCM to swap in, that has HPT support... either the 07 2.2 or the 2.4(though you’d need the appropriate engine either way)

I'd love to manual swap her but what I've heard is it's just such a hassle and pain in the ass to do it that I figured I'd save the head ache and run the auto... Till it explodes I guess then if that happens I'll figure it out lol

Once she explodes

I'll just get everything from a 07 and swap my engine parts over to the 07 2.2l or possibly 2.4l 😉 and run the 07 manual trans with the ecm and bcm from the 07 and do it that way and make even more. Power and easier to tune

You really should contact Trifecta to see if they can tune your car... the physical mounting of clutch pedal and associated hardware seems straightforward, especially if you’re wanting to use standalone engine management, it won’t care what trans is connected to it...

They said they can tune the car but it's just a base kinda map tune they can't dyno tune the car like if I went to a shop or if I wanted to tune it my self using my laptop

Zzp said they aren't able to tune the car unless I use a full Standalone system, AFI asked if my car had a P11 ecm? Which I couldn't figure out
