Hey has anyone looked into swapped a newer sonata head into the 4play??? its a 2.4 wouldnt it bold on? and now having GDI... or maybe even from a 2009 sonata with no gdi?
I couldn't find a fsm for it but just going by the fact that both are "world engines" and fall under the Theta(II) bracket, I would say, yes, they probably compatible.
Seems interesting, I'm going to have to look into it moar.
HEAD, not header.On the OP. What would be the benefit to replacing the headers in a Forte/Koup with the ones from a Sonata?
You tell me. You're still going to burn roughly 20 HP worth of gas to move it down the road at legal highway speeds.^^^
the question on my mind is..
A. how much MpG a tank will you gain from the GDI because maybe in a year that part alone would pay for all the extra work ?
The hot rodders back in the day were also working with carbs and points on an engine that was incredibly inefficient, so just about anything they did was sure to realize gains. They weren't working on engines with millions of dollars worth of R&D sunk into them run by miles of wires and computers as powerful as any commercially available PC.B. Honestly do you think hot rodders back in the day said hey.. that mod is only going to get me a extra 5hp why bother?? NOOO
They said HELL YA Extra 5 hp.. and honestly a extra 30 hp is a nice bump add that with a few other mods and suddenly things are imporving.
If the head physically bolts to the block, you're about as close to having the swap done as you are to landing on the moon by jumping on a trampoline. I've been working on and modifying cars for 23 years, and I can tell you from personal experience that there is no practical reason to go through the immense undertaking of swapping over to GDI for a measly 30 HP. Assuming you even get that much out of it. Remember: the engine is a system, so the GDI engine's bottom end most likely has different internals that contribute to the gain in power. Even something as insignificant as a different pressure spring in the oil pump bypass valve will have an effect. Remember: Ever little bit counts.a person might be able to do this GDI mod alittle cheaper if he / she has the know how to do the work
The physical act of removing a head from one of these engines shouldn't take more than an hour. But as I went over previously, there are much more serious issues to deal with.this is a guide on how to remove the heads in our car i cant find the sonata head diagram but hell it a lot of work for this 30 hp!
