That stuff about the 1.8l and the 2.0l sharing the same pistons but not crank and rods are pure FALSE.

23510-23200 ROD ASSY-CONNECTING 2.0L up to 7/6/1999

So basically, different bore, different pistons, different crank, different rods. But they do share the same block.

Just had to clear up the misinformation.

Just in case you want to look it up yourself.

fastiburon

i don't think you've cleared misinformation

this is really curious...

bore and stroke values you have post is completely different from other all specification published in the web
if you look at http://www.paul128.co.kr/paul/engine/hdgas-spec2.html

stroke should be:
85 mm in 1.8
93.5 mm in 2.0
i'm really really curious !

According an Hyundai Automotive Technician the ONLY difference between the 1.8L and the 2.0 L is the

1) Crankshaft
2) ECU
3) About 10 HP

The correct #'s:

BETA
1.8 D
2.0 D
ENG. MODEL
G4GM
G4GF
Displacement (cc)
1,759
1,975
Bore X Stroke
82.0 X 85.0
82.0 X 93.5

Anyone else have similar numbers?

-Steve</div>I agree with Steve. Don't forget the 1.8L had a higher lift cam of 4 degrees

Oops, the cam, I always forget the cam smile.gif

I wonder if it makes a difference on the application?

</div>This was for a 1.8l Elantra, and a 2.0l Sonata. I just assumed they were the same as the Tib and so forth. rolleyes.gif

Second, I wonder if location makes a difference. Mayhaps the Canadian version differed from the US version in that way.

</div>This i got from the Hyundai UsA Online parts site. Here's the link again.
Even if the stats arent the same the part #'s are still different. No company in their right mind would give the same part two different part #'s.

If they a different crankshaft then they would have to have different connecting rods otherwise the piston would be getting into fight with the valves.

Although I have advocated checking the Hyundai online sources on the past, I would only trust these catalogs as far as I can throw them(which isn't very far consider it is a virtual list).

Hyundai Webtech has already proven itself fairly unreliable in differentiating even the second gen tiburons from the first gen, I wouldn't take their Extranet parts lists as golden either.

Random

The crank is differnt between the 1.8L and the 2.0L and also has different rods. That is how they get the .2L displacement difference. They share the same sized pistions.

The 2.0L Sonata is NOT a beta engine. That is probably where the confusion is coming from.

I've had both the 1.8l and 2.0 and I want to really clear up the difference.

As Random has mentioned its only the crank and rods that are different between the two motors.
Everything else is identical.
I have a 1.8L Tib and the difference between the two motors are pretty much the same HP?
