if you are looking for an ez swap this isn't it.

With some clever engineering, a nice tig welder and some patience, you can swap the 4G63 into the Tiburon. There's enough room and you won't have to shoe horn it in, but it's definitely not an easy swap like a Honda swap. A couple people have done it, and there is a 4G63 2G Tiburon here locally. It's actually quite impressive.

if you do the evo 4g63t not the eclipse. there is a group from thailand that does the swap. but i think for what u spend on it aint worth it.

Or you could just boost the 2.0 in the Tib? Cause.. umm, they respond REALLY REALLY well to boost. With a good tune and a good set-up 12-14psi could equal 300 whp. I dont see alot of evo's or 4g's running that low of boost getting that much horsepower.
Keep the engine hyundai, it has more potential then a 4g. Why do you think the Hyundai block and the 4g block look very similar? Cause hyundai knew the 4g was a good engine, but they new where its problems were. And when they made the Beta (your 2.0) they copied the 4g but fixed all its issuies. So no crank walk, no leaking rings, good flowing head.
I dont see why anyone would even want to get rid of the Beta. Sure parts are harder to find, but should that really hold you back?

Umm the reason EVO motors don't make 300HP @ 12 psi is they have lower compression so they can boost safer if they had 9.5:1 compression they'd make the 300HP just like a beta. Look at any turbo motor from the factory I can't thin of any that come with more than 8.5:1 compression. Why? Because high compression makes it a much more difficult to tune it's a fine line to walk on tune between good power and a grenading the motor... Also the ring lands on beta motors are too thin if you get a bit of knock you'll break a ring land compare the piston crown of a 4g63t and a Beta you'll see exactly what I mean. This is fixed by getting custom aftermarket pistons like Ross Racing etc.wilburisthecoolest said:

The 4g63t is way better than the beta.
Not if you're looking for a motor to go in the Tib. Boosting a Beta costs less than half what it would cost to swap in a 4G63, which is mounted backwards compared to a Beta.
I concur. Sell your buy car and eclipse if you want the 4g63. It will be way cheaper and 200hp out of the box.

I have a 01 boosted tiburon that is only running 9 PSI at the moment. i am literally at the dyno shop right now and they are hooking up the Wide Band to see if i can get more the 188 whp/240 tq (which is what i got from my first tune). i like the fact that you said its kind of like the 4g63 but with the quirks worked out, that is very reassuring. i will post again soon to let you know what i put down. oh thats right the guy that dynoed it said i wasnt get? thanks in advanceOr you could just boost the 2.0 in the Tib?

Hmm what are these "quirks"?
The 4g63 is more durable and suited for boost in everyway. From the iron block to the low valve angle ports, the lack of need for unshrouding the valves from the factory, the thick ass ring lands that resist knock, the deep nitrided, forged crank, a decent large intake manifold and throttle body from the factory, a drive train rated at twice the torque rating of the tiburon, rods that handle things the stock beta would cry about, stock headgasket that when paired with h11 tool steel head bolts can handle 600hp, larger injectors, better fuel pump, cracked ecu, valvetrain that has been proven to handle 8500 rpm reliably.
Yeah, I guess those were all "quirks" that needed to be "worked out".
I dare anyone to argue with me.
I read that you can do the swap but would have to use a 4g63 engine from a japanese evo 4/5/6 because of the side the tranny is connected. I just got a tib from my uncle and I am really looking into modding it to a hp goal around 450. If a 4g63 can be swapped in wich one should i go with and what tranny should i use for fwd?
THNX in advance
