eclipse gs 4g64
 

what heads would be good to use on my 2.4l engine eclipse
its a 4g64 engine

If you are building the motor and running a turbo the Evo8 head is the best you can do for a swap. Otherwise it is useless

wouldnt the srt4 head fit..

I am not possitive. If I had to guess i'd say no. I know the Evo 8 head will with some work. Again unless you are building the bottom end and turboing the car looking for 400+ WHP it is worthless to do

I thought the evo 9 would fit.... Ima change da head first n than turbo it later

Someone told me da evo head won't fit... It would still fit even though da evo has a 2.0 n mines a 2.4?

You can use the 4g63 dohc head, it should be a direct bolt on. Also a 2g 4g63t exhaust manifold will bolt right up to the 4g64 sohc head.

The Evo 9 head won't work, the Evo 8 head will. FYI alot of Evo guys stroke thier motors. They use the 4g64 crank in order to do so. Which essencially makes it pretty much the same as what you have. With the exception your internals are not all that strong.

DON'T do a head swap first. That makes no sence at all. Plus it would actually be cheaper to go turbo first. You still need a built bottom end before the head swap as well. the reason is because the stock head and bottom end internals are only going to make mid 300WHP range at best. before you break the motor down. If you are not looking for more than that it is a waste to built the motor and swap and Evo head.

Being honest the cost to do what you want is so great that it will BY FAR out value the car and you will never get the return.

So jus turbo it with the sohc head.. N dnt change the head?? Jus use da stock one??

Could I use an head from the older model jus so I can make it dohc??

Yes exactly. Based on your questions I am going to say this, Do alot of research and stop asking basicly the same question over and over. I am breaking it down very easily for you at this point. Now you need to research all the parts needed to turbo your car.

You are looking at spending somewhere around $10-$15,000 at least in order to only get like 400-450WHP. It is not worth it. you could just buy an Evo 8 for that now and already have a car that will better suited. Just to turbo your car only without building the block or doing a head swap is still going to cost around $4000 and your car will only beable to make around 300WHP without starting to put your motor at risk.

Older Evo heads the only one that will work is the Evo7 since it is exactly the same as the Evo8 but harder to get and pointless. Anything older than that will not work because the motor faces a different direction than your Eclipse.

That's the point of the evo 8 head swap, our 3g eclipse's cam gears are on the left when looking into the engine, the 2g eclipse is mirror image of ours, everything is opposite, even tranz is on opposite side, the Evo 8 (mitsubishi lancer evolution VIII 2003-2005) is the ONLY head swap we can do that will work, also if you're doing a turbo i suggest using the Evo 5 after market radiator, it has both upper and lower water necks to the right side so they're out of the way plus it's a dual core instead of our pathetic 5/8 inch radiator. i'm new to this forum, not the car. i am currently in the middle of a evo 8 head swap w/ Garrett gt4088r turbo; over all goal around 625 to the wheels, also if you really wanna spend the money you can convert to awd and do full evo 8 engine swap, everything does fit, just some mod required, but remember, with awd it's a 30% drive train loss. so for power and money wise, evo 8 swap is the way to go, but this is NOT for the unexperienced, this is a SERIOUS project, i'm already 4k deep into this and i still need another 9k. reason being, i'm buying everything top of the line. NO EGAY crap. :D
