Tiburon/3000gt

[adidas_coin]

I wanted to know if anyone knows the interchangeability, of an 03 Tib and a 6g72. they share allot of parts from what i hear, wondered if the heads of a vr4 would work on a tib, better flow and all. lemmie know.

the V6 Tib uses the NA 6g72. Hope that helps

Hyundai buys a LOT of motors from Mitsu.

Uh, the 6g72 is a 3.0L. The Tiburon is 2.7L. So while it may share most of the same components, it's not a 6g72.

That'd be like calling a 4g63 a 4g64.

I'm pretty sure he knows that - his question is about heads. displacement can be had by a different crank and pistons - same bore + longer stroke makes more displacement. Why do you think a 4g64 crank in a 4g63 with the right pistons makes a 2.3L stroker motor? Or how 4G63 heads bolt onto a 4g64 block? I would guess that turbo 6g72 heads would mate up to the block if NA 6g72 heads will as long as the only difference is in the valvetrain and cams.

I didn't know the size of the engine, maybe it's a different crank inside the 6g72 block. I've just seen pics of the Tib engine bay and it looks IDENTICAL to the 3kgt 3.0L

they're not the same motor, in fact in about 2-3 years mitsubishi will start buying motor from hyundai (chrylser will be as well).

The 4g64 has an entirely different block than the 4g63. Did you read number 3 before you posted?

"3. No Guesses - if you don't know, don't reply - don't spread misinformation (no "I think" or "I guess" or "I've heard"). "

Not trying to be an ass, but all the "information" thus far in this thread has been guesses... stated as fact. "Well, I looked at the 4g63 block in the EVO and it looked the same as my 4g63 Eclipse block, so they are the same." Uh, I don't think so.

Besides, the statement was made that Mitsubishi buys motors from Hyundai, which also isn't true. The 4g63 was jointly developed with Hyundai and appeared in Hyundai cars badged as the "Beta" engine. Quite a difference than a motor built by Hyundai on it's own.

Maybe some of the Hyundai guys know. www.hyundaiperformance.com

The 4G63 was used in some Hyundais, but it was devloped by Mitsubishi. Current Hyundais do not use Mitsu engines anymore (96+ I think, hence the new nomenclature Beta, Delta, etc). So an 03 Tiburon will not be interchangable with a 6g72.

There was recently a joint venture between DCX, Hyundai and Mitsubishi to produce an all aluminum "world" engine that has 1.8, 2.0, and 2.4L variants both N/A and turbo. That was JUST completed and none of those engines will show up in ANY car for 2-3 years yet. It won't be in any Mitsubishis until around 2007 when the new Lancer comes out.

That all being said, good luck with your Hyundai 6G72 swap. I would just stick to performance parts designed for that car and that engine, and leave it at that.

yea i can't wait for the new world engines to come out. they have an expected lifespan of 300,000 miles and i'd love to have a turbo tiburon on my lot

as for the parts interchangeability i don't think you'd want any parts from the tiburon anyways since its a 2.7 making only 175 hp where as the dohc 3.0 in a 3000gt makes like 220. seems like anything you'd swap would be a step down to me.

maybe he was talking about swapping from the 3000GT to the Tiburon? Either way, starting with that much displacement is great. 2.7 liters is more then a Skyline has, remember, and those motors can be pushed to 1,000+ horsepower. Not saying that a 2.7 tibby could do 1,000 horsepower, but as far as forced induction is concerned, every tenth of a liter is a godsend. Turbo that 2.7, I say, and make 700 streetable horsepower, and make all the Honda, 420A, 4G63, Nissan, and Toyota guys jealous.

Once upon a time, in a far away country "korea" Hundai(however its spelled) bought blueprints from mitsu, namely the 4g and the 6g, they did of course change certain internals as far as size and materials used but the block that they are based on in either case for the most part is the same.
