As i wrote in other post:
1600 cc beta in tiburon
77.4 x 85 bore x stroke
able to be bored UP TO 82 mm
compression ratio:
9.7:1(114 cv 6100,143nm 3000rpm)
9.9:1(116 cv 6100,143nm 3000rpm)
gear ratio:
I:3.46 II:1.95 III:1,39 IV:1.06 V:0,84
reverse: 3.25 differential: 4.06.
stock tire: 205-50-15
many use 195.50.15 for acceleration
when i bought my car it was 1.6
my first step was:
-removed resonator
-replaced my stock filter
-installed hose from stock filter housing down to radiator.
i did'nt noticed ANY improvement except sound.
so i went in a performance shop for a BBTB bored IM and possibly mufflerheaders.
the guys honestly said: there is little or nothing to do with 1.6 staying NA WITHOUT AFFETCTING LOW END POWER.
BBTB and ported IM:
rough idle and no significative performance increment.
resetting ecu solved idle problem.
according to him ( shop mechanic ) the underbored 1.6 engine share all with 2.0 exept crank rod and pistons.
it has the same head with same valve train,
same IM, same TB, same injectors, same headers, cat and same stock muffler.
all with same diameteers and size.
so i will noticed little or nothing with different exaust because diameters are enough for 1.6.
guys prospected three ways:
-overbore the 1.6 to 1.790-1.820 cc
-search a 2.0 engine from wrecked car
-use a delta hf turbo
i found a 2000 engine with 36000 km at ...
about 500 $
swap with 1.6 trasmission is very simple.
i use 1.6 cam and 1.6 ecu with a eprom chip properly tuned.
i've also bbtm and ib and my semicustom CAI
and stock exaust.
I'M very satisfied. i can use my gears as... my KTM 250.
i hit 210 kmh in speedometer... so my turbo project can wait

The 1.6 cam is the same as 1.8, which is better for the 2.0 than stock one right? So, to go from 1.6 to 2.0 you would need to overbore the block to 1.8 Spec, and change crankshaft, con rods and pistons. The ECU can be reprogramed, right?
Also, are the gear ratios different?
Anybody can show like a table to watch the differences (if there are any) between 1.6, 1.8 and 2.0?
Thanks

here you found beta specifications:
http://www.paul128.co.kr/paul/engine/hdgas-spec2.html
i ve also a detailed brochure of 2k models specification in europe (i'll scan and post):
Gear ratio:
differential ratio:
1.6 = 4.056
1.8 = 3.842
2.0 = 3.650
tib and elantra have same differential ratio (related to displacement)
I gear:
1.6, 1.8 tib = 3.462
2.0 tib = 3.380
1.6, 2.0 ela = 3.62
we have no 1.8 elantra in europe
II gear
1.6, 1.8, 2.0 tib = 1.950
1.6, 2.0 elantra = 2.05
III gear
1.6, 1.8, 2.0 tib,ela = 1.393
IV gear
1.6, 1.8 tib = 1.061
1.6, 2.0 ela = 1.061
2.0 tib = 1.031
V gear
1.6 ela = 0.878
1.6 tib = 0.837
2.0 ela = 0.837 (same of 1.6 tib)
1.8 tib = 0.825
2.0 tib = 0.780
1.6 elantra and 1.6 tib has similar gear ratio except for I II and V ... a little shorter.
about displacement...
1.6 BETA 77.5 X 85 OVERBORED TO 82
IS EXACTLY 1.8 cc BETA
you can use stock hyundai pistons
or use low compression piston for forced induction. NO CRANK NO RODS
1.6 beta overbored to 82 with 2.0 crank rods and pistons will be 2.0 cc
howewer expansive to do ...
may be easy buy a 2.0 engine from wrecked car.
ABOUT CAMS:
attending my dealer service mechanic 1.6 exaust cams have same part number of 1.8
but 1.6 intake cam has different part number.
anyway i'm not sure, i should personally see! ( sorry for my english )
about ecu ask to your service mechanic if he can rewrite your stock ecu with 2.0 map.
my mechanic installed a PLXracing chip and tuned it.

Thank You smile.gif This is going to be a lot of help! Yes I think it would be easier to get an engine from a wrecked car, because crankshaft and rods are expensive parts.
Thank you all for the help.
(and never mind your english, it's perfectly understandable, at least for us non-english speakers
)

Tasos, could you explain please that EPROM thing please?
Also, if the 2.0 has bigger displacement at least in theory it would need more fuel to keep the air/fuel ratio balanced right?
If I bored my engine to use 1.8 pistons, would I have to change/reprograme the ECU? or just a chip?

<div class='quotetop'>QUOTE</div><div class='quotemain'>"Tasos, could you explain please that EPROM thing please?"</div>Well the chip everyone says about is actually an EPROM wich "contains" info about the timing and fuel management.The 2.0L has different timings than the 1.6L...the injectors stay open longer thus spraying more fuel in it and the duration is different vs the load of the engine. IN simple words the MAP-table the EPROM of the ECU of th 2.0L is different than that of the 1.6L
BUT since you use the injectors of the 2.0L which are 220cc/min instead of the 180cc/min of the 1.6L the total HP loss resulting is 2-3Horses...Have been measured.The engine will run otherwise just fine with absoluterly no problem.When we do engine swaps,unless you ask for it they leave the ECU intact.Also other issues prevents us from changing ECU as the IMMOBILIZER and the need for different keys...
If you want you can unsolder the EPROM and replace it with a chip-base for an EEPROM at which a chip-tunner can tune your 1.6 ECU to work just perfect with the 2.0L engine....
That means that they can put in the base different chips with different programs,or even can have a laptop to emulate the EEPROM realtime and when the tunning is done then burn at an EPROM the new program and put it in place...
Thats the best case.Something similar is done when you install a SUPERCHIP (its an EPROM actually) at you ECU...
That's what I mean when saying "reprogram you ECU"
<div class='quotetop'>QUOTE</div><div class='quotemain'>"Also, if the 2.0 has bigger displacement at least in theory it would need more fuel to keep the air/fuel ratio balanced right? "</div>
YES its right so its better to use the 2.0L injectors or even biggers so that the tunning can be done more "properly"
<div class='quotetop'>QUOTE</div><div class='quotemain'>"If I bored my engine to use 1.8 pistons, would I have to change/reprograme the ECU? or just a chip? "</div>
I think I have already answered that above. You can leave your ECU intact and reprogram it later (chip it),or you can reprogram it instantly, ot you can leave it intact for life...Its up to what you want and how much money you want to spend and if you can find a good tunner, with knowledge...
If you want more,just let me know...

This thread is ALIVE!!! (again)
As far as I know, the only similarities between the 1.6 Beta and Alpha is that they are both made by Hyundai and they both have (roughly) the same displacement.

in italy we have both 1.6 alpha (G4ED engine)
and 1.6 beta (G4GM) mounted on coupe 1.6.
the newer version of II gen 1.6 and 2k03 1.6 and matrix 1.6 have 1.6 alpha G4ED to meet euro3 emission.
howewer attending my dealership mechanic
they have the same tranny.
SO there isn't any 1.6 beta now in production.
howewer 1.6 beta common mods are head squish, air filter, bored TB/IM, muffler, ecu chip.
