I know that some1 probably already asked that question before me, and I tried to search it , but couldn't find anything, so I was wondering if it's possible to make my Single Cam 2.4L from Mitsubishi Eclipse 2001 GS to Twin cam, and if it's possible can some1 give me list of parts or something.
Thanks

Here you go here is a good bit of research by my friend 00TampaBlueGS

Thanks, B. :hug3: Saved me the trouble of digging through my 'Subscriptions'. ;)

I started the thread as a complete newbie to the concept. Kind of lost my energy when the weather started getting nice again. Still, it's a good starting point. Hope it'll help you through some of the basic concepts and lead you in the right direction.

I do have things I could add and some reformatting I'd considered. Maybe I'll update the thread before long now that winter's on the way. Thought about it a few times, but... :loser:meh. Energy's gone to other things.

Well , as far as read the post by TampaBlue I found out that I need about $1500 - 3000 to do the swap, with turbo kit that I was looking forward to buy I need about $3500 ( turbokits.com ) , so I was wondering what's better on producing more power, Swap or turbo, as far as I know before the turbo I need to upgrade my pistons, ECU , injectors, spark plugs etc. to make it run good and push about 15 psi.

Without a turbo the head swap alone isn't going to give you that much of a gain. If it's one or the other, turbo it. But from what your knowledge base seems to be, I'd read a whole hell of a lot before even buying anything if I were you.

I'm no expert on the subject but I do know that with an evo or kia DOHC head swap and built bottom end you can run a LOT more boost and therefore produce far more HP than if you just turbo w/o swaping the head.
Guy's who turbo w/o headswapping usually run about 8psi of boost and make around 200 whp. Some people who have done the head swap and turbo are making 300HP or more.

you can make 300hp on a stock head at 15psi at ground level. It has been done before. the only problem is tuning the turbo kit, since our ecu's limited. Our bottom end is fairly strong. Most evo guys go after our cranks cause they can stand the pressure and the RPM of a 2.3L stroker motor.

^ Yes, it's been done.
Our bottom end (including the pistons) is pretty strong, just as cyberbrain says. You may be confusing our pistons for the soda cans the 6g72 pushes. With the proper tuning, 15+ psi is manageable on a stock 4g64. I've even seen evidence of some pushing over 20 psi to good effect.
Search for posts by kng nothg. I believe he did it. Last I heard from him, he was also going after a twin-cam head swap as well as AWD. :)

I heard that some boost 24psi on stock 3G and it holded it fine, ( they posted a video ), but most people told me that it's pointless to do that, because it's not that big of a dif. then boosting 15psi, except that with 24psi ur car most likely will overheat w/o hella good tuning
