Engine upgrades replicate Elantra-from-Lantra improvements, ie:

Redesigned block with external contouring of cylinder bores (ilo flat sides), extra ribbing & one extra transaxle fixing point (now 5)(less NVH)
Crankshaft now has 8 counterweights ilo 4.(NVH)
Cast & ribbed aluminium sump pan (ilo pressed steel sheet) with stronger joint to transaxle (NVH)
Reshaped combustion chambers, ports & pistons (performance, [fuel] economy, emissions)
20mm longer intake rams, 8% smaller surge tank, resonator added, spark timing & valve lift optimized, lighter valve springs, denser conrod bearings, returnless fuel system (ilo return type) with higher fuel pressure & smaller injectors (torque spread & econ)
Cylinder head machined to more precise tolerances
Head gasket now 2-layer (ilo 3)
Idle speed reduced to 700 rpm from 800 rpm (NVH)
Hydraulic engine mounts (4) ilo rubber (NVH)
Heat shield installed between engine & air filter, reducing heating of induction air (+2% output).
New camcover with I-piece high-specific gravity polypropylene baffle (ilo 2-piece pp)
Oil flow reduced (econ)
Mechanical valve lash adjusters (solid lifters) replace hydraulic, improving valve clearance precision (durability).
Lower valve spring load reduces valve train friction (perf).
Engine cover installed (NVH & dress up engine bay)
Catalytic converter now upstream adjoining exhaust manifold (ilo under car) (emissions)
Other detail changes to: alternator, intake manifold brace, power steering & a/c pulleys, idle speed actuator, oil filler cap & drive plate between engine & torque converter

sticky that shiit...

the beta II engines also have a higher output alternator

you looked for this after we talked yesterday didnt you?

yep, I was researchin about MFA60 tranny, and found this ^^

Will the Beta II alternator bolt on & plug into the harness for the 2000-01?

I would like to know the alternator question as well.

"Catalytic converter now upstream adjoining exhaust manifold (ilo under car) (emissions)"

Mine is part of the manifold... what does this mean? They didn't change anything did they?

Are they talking about changes since 96?

Could be because I think the 96 and 97 had the cat converter separate from the exhaust manifold. My 1999 tibs exhaust manifold was the same as yours.

I think the alt is the same for hooking up. I have one of each in the garage. Ill look if I remember.

This is your memory remembering you to look at the connections.

Thanks!

they bolt to the same place but they wont hook up. the beta2 sensors are completely diffrent and will not be compatable AT ALL !!!!!!!!!!


oil temp sensor looks the same but i still changed it.

i'm going to do a post on EVERY diffrence with pics here this weekend. so hold on and i'll come thru for you on any other diffrences

Is there any difference in the gear box as I want to do a beta1-2 swap including box but just want to know if the drive shafts ect are the same.

Nobody knows sad.gif

tons of people have swapped to a beta II transmission.. its a DIRECT swap, just need to grind down the rear roll stop bracket.

gearing is a TAD longer in the beta II, but thats it.

i had a beta II trans in my tib.

beta2 tranny is WAYYY better for trips and also 3rd/4th pulls way longer. 4th gear is like 120mph after swap

The beta2 in the elantra has longer gearing. The one in the GK does not. It has a shorter FGR making the gears closer together.

Thanks for the info guys fing02.gif

<u>Few important things to add;</u>
G4GF (beta1 2.0L)
MAF
comp ratio 10.3:1
hydraulic lifters

G4GC (beta2)
MAP
comp ratio 10:1
mechanical sim based valves

G4GC (beta2)
MAF
CVVT on the intake side
comp ratio 10:1

Careful, because there is actually 3 different beta 2 heads. The main thing to look for is MAP or MAF.

^^ u forgot the G4GC beta2 without cvvt MAF based

I read that beta 2 tranny is a direct swap. Does that mean that I can use a beta2 clutch in my beta1 (stock tranny)?

Uhm, duh?

No offense, but it's been posted a few hundred times.

Why do you have to asnwer like that? A simple yes would give the same answer wink1.gif

I asked it because the local clutch seller told me that it wouldn't fit.

If you are too stupid to search, you get the answer you deserve.
drillsergeant.gif cool.gif

Its better to ask it then searching for hours reading almost everytopic in the search results wink1.gif

Its better to just help somebody then post stupid messages like you are doing now redz

No, it's better to get someone to help themselves then to spoon feed them like a 2 year old. Don't post in here again unless you are adding to the topic.

Warned.

And it's not better at all. It's better to READ all of those results, so you have a firm grip on what you are doing, and can help others later, or know where to reference things. It's better to learn how to effectively search.

Faster/Easier for lazy asses doesn't mean better.

Is there now a Beta3? Reason I ask is while in New Zealand I saw one of those Kia Sorato Koups, the 2.0 engine looked like a Beta, but was all aluminium, and power upped by 96bhp.

Also it appears the fit of the crank pulleys are slightly different between Beta1 and 2, as many UK owners have brought lightweight ones for their Gen3 (Beta2) and its not fitted, but will fit older Gen1 (Beta1), yet its sold as a pulley that'l fit any 2.0 Coupe.

copied this which I posted on the Uk site after many were asking about transferring CAIs between Beta1s and Beta2s.



when fitting a Gen1 SRI to a Gen3, which can be fitted, but leaves a blanked off pipe that don't look to good, but more importantly means throttle bodies cannot be transferred between otherwise identical inlet manifolds.



Look at a Beta1 intake, off my 2.0 Gen1, note the idle control pipe and valve at the back, and the 2 top TB bolts sitting level, as arrowed.

Now a beta2 intake, off a 2.0 Gen3, not no idle control at the back, and the top left bolt is sticking up, this is because the idle control is under it, internally in the TB, meaning if you try and fit a Gen1 TB to a gen3 intake, firstly only 3 bolts will line up, not all 4, and secondly you'll block off your idle control line. Also note the saggy pipe that had to be blanked off as i fitted a Gen1 SRI to a Gen3, and that spur off the intake wasn't needed.

Also, with a few minor diy modifacations I have repaired my wifes Beta2 big end bearing failure using my spare Beta1 block. Kept her VVT head, and aluminium sump, and sandwiched a Beta1 block in. had to swap the crankshaft oil seal housing at the flywheel end to do this, as 2 of the bolt holes are moved, so fitted Beta2 one onto side of Beta1 block, had to use a Beta1 flywheel as the hubs they fit onto are different sizes. The only ballache I'm having is getting the CPS (another difference, Beta1 uses magnetic pickup off the crank, Beta2 uses hall effect, basicly sends a 5v signal from ecu through sensor) orientated, I have a realy old Beta1 block, so CPS sits rotated at right angles to where it should be, so I had to make up a bracket, but make it so I could play with the CPS to get it in the right position. It runs perfectly, no problems at all.

Let me add some internal differences with pics to help out.



First and biggest are the valves. Beta 1 are shorter to allow for the expansion of the hydraulic valve inside the lifter.

Here are some pics of the Ferrea valve springs with seats and retainers, they are shorter than the stock ones (which are from a Beta 2), the Ferrea springs are slightly shorter than the stock ones but once compressed and seated on the valve they will be fine.

Here is the oil valve in the Beta 1 block, between the 2nd and 3rd cylinder
