our heads is the same as the evo x, lancers, srt4. right now i have a 2.0 lancer head waiting to be port/polish it fits guys really simple research. you can also add evo x stock camshafts. lancers do this all the time the put evo x stock camshafts in the 2.4 lancer gts head, basiclly we have a lancer motor in a kia. the block changes but the head is the same.

For starters the exhaust ports are different shapes plus the heads have different ports/outlets then ours does as well. Also a different waterpump hard line as well. Not so simple research has led me to those discoveries.

My forte is 2.4 2012. The head I bought is from a lancer 2.0 2010. I personaly went to kia auto parts with the lancer 2.0 head and placed a gasket of my forte 2.4 head on the lancer head. The gasket matches exactly the ports and emmisions. I can uplod a photo if you want. Also look at the specs of the 4b12 and compare it with the theta 2.4 motor. You will see we have the same compression, same bore/stroke, same 2,539 cc. These motors are used by chrysler and mitsubishi and hyundai and kia with diferrent codenames. Hyundai manufactures the though. See for yourself, see the links I added and compare the engine specs.

lol I dont need to see wiki pages, ive done my fair share of research. And just because the gasket lines up, doesnt mean squat. There are all kinds of ports, as well as the waterpump, thermostat, electronics, etc. that is all in different locations.

When the motor collaboration was started, they were all given the same blueprints, but each company built almost entirely different motors. The evo x manifold actually does fit on our car, I tried it, but good luck getting that turbo to fit back there. The water pump hard line got in the way, along with the heater core lines, firewall, etc. Why? Because the heads were designed differently.

There is more to a head then just the gasket shape. But hey, if you wanna drop the money and try it, go ahead, im not stopping you, but chances are it wont work. and even if it DID, you would need a custom intake manifold and custom exhaust manifold to start ;)

I am not interested in turbocharging my car I plan to use parts for apirated. I am not stating that all of components are the same of course los of thing changes like the ecu. I am only saying that for apirated cars we can use these parts. Now turbo is a different story and almost does not apply

Even naturally aspirated you would need.

1. New intake manifold
2. New exhaust manifold
3. New water pump
4. New water pump hard line
5. New thermostat

just to get started.

Parts like cams, pulley, heads. Not waterpumps or ecu or wategates. Your getting out off my topic. What I still can`t find is a good damn header. Only thing I can do is port the outersides of stock header. Yo plan on making yours turbo?

Anyway that I will do is port/polish the head an cut the head at 20. Then tune. Should give a 5 to 8 hp. right now I have 170 and with this setup Hopefully I will be able to hit 180 or close. We`ll see

Mines already turbocharged. And what im saying is you cant just swap the head without expecting to swap other parts as well such as the waterpump, thermostat, etc.

What I would do is just modify the stock header. Cut off the 4-1 collector (which pinches the pipes up and restricts it) and weld in a non restrictive 4-1 collector.

Yeah think I will go with that since finding a good header for our cars is like almost hopless lol . One Question... in what the waterpump, thermostat involes or affects the head? Just to know
