Maybe a dumb question, but do you think it'd be possible to swap out the I4 Theta to the HD? I'm considering some wild choices for my mid 20's sportscar... just looking ahead wistfully.

Well, anything is possible with enough money and fabrication. Your first hurdle will be getting the orientation to change from longitudinal to transverse. Then finding a transmission that will hook up to it, and the front wheels. Some of these issues may be addressed when the new Tucson is out, as it's supposed to have the same turbo engine as the G Coupe.

Just to confirm, it is a dumb question. What Mike said.

The Sonata comes with a Theta in a FWD configuration so making it transverse and finding a trans isn't a problem. Granted it's not the turbo Theta but adding a turbo to a non-turbo Theta shouldn't be hard.

Yes, but the Sonata has a Theta 2.4. I am assuming the question was regarding the Turbo Theta 2.0. I'm not sure how different the 2.0 and 2.4 are, I've never compared them.

Externally that should be similar. The dispacement is based on the bore and stroke, not the external dimentions.

the tranny is on the other side so youd have to ditch the elantra config

well, let me rephrase that. the motor is mounted backwards compared to the elantra

Not true. The Sonata and Elantra have the trans on the driver side.

Plus, the Kia Rondo has a 2.0 Theta.

Wikipedia might be off, the Optima comes with the 2.4L or a 2.7L v6. Same witht he Rhondo.

EDIT: you edited and I edited and now it's confusing.

Clarifying: you first said the Rhondo and Optima had a 2.0. i said no. you removed Optima from your post, added wiki link - which says the Rhondo comes with the 2.0 only in Australia.

The Rondo has the 2.0 Theta but not in the US.

Haha, it happened again, I saw that it was the G4KA engine, and edited my post, but you got the quote in just before I did.

you can do anything you want...but the theta is mounted the opposite way (intake first like the 2.4 theta) and the theta uses the delphi system and not the siemens system like the beta III (IIRC)

The Theta is not "mounted the opposite way". It's mounted the same way with the front of the engine (belts and pulleys) to the left (passenger side) and the rear of the engine (trans) to the right (drivers side).

However, the intake and exhaust manifolds are on opposite sides of the head compared to the Beta. So the intake is on the radiator side of the block on the Theta while the intake is on the firewall side of the block on the Beta.

True. I have seen a Honda Civic CRX with a big-block and upswept open headers coming through the hood. Cosmetic fitment may not be the same as mechanical fitment, YMMV!

Oh what the hell, if you're going to put the 2.4L Sonata engine and transmission in there for another 30hp, or see if the Genesis Coupe 2.0 turbo fits sideways or bolts onto the Sonata bits, why not just aim for the 290hp Evolution X engine that's allegedly the same block anyway?

It's already transverse in the Evo X, as it is in the Sonata. The transmission is on the same side (driver's side), but the exhaust is in the rear. If you still have time and money left over, you can swap the TC-SST and AWD :D

Thanks Hyunelan2 for the epic threadjack, I didn't realize that this question would get serious attention!

I only was interested in the GenCoupe engine because of the stock turbo and promised aftermarket support. Plus, I still think that Hyundai's next move with the Tiburon will be a 2-door Elantra, shelving the Tiburon brand entirely (That's what I'd do). I like the numbers (economy and power) of that turbo Theta.

Agreed. I just repaired a 2007 Sonata with the 2.4 theta in it and it is in the same configuration as the Elantra.
