Default BETA 2 Engines

Hi all, i would like to find out some info regarding this engine.

as per wikipedia

<div class='quotetop'>QUOTE </div><div class='quotemain'>Beta II

During 2001-2002, the new Beta II engine made its debut in models such as the XD Elantra and GK Tiburon. Output is 138 hp (102 kW) at 6000 rpm with 136 foot-pounds force (184 Nm) of torque (184 Nm) at 4500 rpm. It has a cast iron engine block and aluminum DOHC cylinder heads. The latest version of the 2.0L Beta engine (G4GC) features CVVT, which exists only on the intake side, a first for Hyundai/Kia. The following changes were noted.</div>

i have never seen a BETA 2 Engine, how would i distinguish between a BETA 2 and a Beta 2 with CCVT?

Hyundai use's the following engine codes for ther beta's 1.6= G4GR 1.8= G4GM 2.0=G4GF BETA 2 2001-2002 2.0=? and beta 2 with ccvt=G4GC but none of these numbers appear on the block?

these are the 2.0 engine i have seen.
the J2 2.0 (im Guessing this is the J2 Series Elantra here is a pic of the J2.1.6


then there is this engine the XD 2.0 from what motor does this car come out of ? is it a Beta 2 ? it had no tappet cover so it look very similar to the beta 1 or is it out of something other than a elantra ? will a Tuscons 2.0 use the Identical engine to a Tiburon 2.0 or elantra 2.0?



so if anyone has seen there Engine block on the elantra please let me what it says...

THANKS

IIRC it has CVVT if you see a sensor coming out of the nub that sticks out on the top drivers side of the motor .

xd20 blocks are beta engines, beta 1 uses black top cover(sparks cover), beta 2 uses grey top cover(sparks cover) also in the front right corner it say non-cvvt or cvvt, a simplest way to know is looking if it uses airflow or map (talking about xd20 only) beta 2 non.cvvt uses map, beta 2 cvvt uses airflow, dont get confued with the airflow of j2 that is not beta engine. airflow of beta 2 cvvt engines has airflow meter and ITS(intake temp sensor) inside itself, j2 uses airflow meter and in the intake uses ITS apart



i had J2, xd beta 1, beta 2 and beta 2 cvvt so i know many differences

It would've come out of a RD Coupe/Tiburon and would've indicated the 1.8L base engine, as opposed to the 2.0L option which would've been stamped as RD20. Either way, it's a Beta I engine, whereas the XD Elantra's and next generation Tiburon/Tuscani would've had the Beta II's. Safe bet is that anything 2001 onwards would've had the Beta II engine.



Speaking of the Wikipedia entry, I was the person who put up the info on that page many years ago, which was a copy and paste job from a page I found with all the changes from the previous Beta engine (was referenced to satisfy the Wikipedia standards). If anyone can find similar documented changes with the CVVT version, feel free to add to that page as such.
