the alpha is the 1.6L DOHC for the Accent, the Beta is the 2.0L DOHC for the Tib, both are the first developped by Hyundai engineers. Anyway, I think that's it? Right boys??

The Alpha one was the Scoupe's(1993-1995) engine. The Alpha II was the 1.5 L for the Accent in 1995. The Alpha III is the new 1.6L DOHC Accent motor. The Beta motor is the 2.0L Elantra and Tiburon motors. A little OT, the 2.7L V6 2002 Sonata, 2002 Tiburon, and Santa Fe engine is the Delta platform.<img src=icon_smile_big.gif border=0 align=middle>

And the Beta II will be found in all the 2002+ Tibs and Elantras. It has a newly designed head with solid shims replacing the HLAs and it is MAP sensor based rather than MAF.

Rob do you know if the new designed head with the shims and such will be directly interchangeable with the current beta engine heads and such??
HOw much of an improvement over the old heads are the newly designed heads supposed to deliver?

It is a direct swap onto the 1G Beta blocks. The main difference is that with the new solid shims, the beta head can be revved up past 8000RPM which was the motor was previously limited to by the HLAs.

This is a HUGE advance for N/A tuners.

Good cuz that's what I am.
SO if ya can rev up past 8000 rpms what about the rev limiter?

You'll hafta excuse me man I don't know that much about this **** but I am way interested in any all motor advancements. DAt why i want to mod this forum.

And what about the map? if you were toswitch over which I know would most likely be a PITA would that benefit for us NA guys?

Actually, the MAP would be better for N/A, while the MAF would be better for turbo.

As far as the high revving, you'd need to build up your head with springs, lighter valves, strong retainers, stuff like that. RPW (http://www.rpw.com.au) could help you with any of that you needed though.

this new beta motor being a map based engine ... would it be able to bolt directly to the 2000 tranny no problems?
also if you switched engines like that (which i want another engine anyways as i can always have a spare) and kept it map based that means you would need to get the ecu that comes with that engine itself right?

i think these are stupid questions ... but is there anything at all in what i am asking that would make this particular swap impossible? or a big PITA?

I'm guessing you need to replace a whole lot of sensors and a new ECU. Might want to do a search on fxtreme because I remember someone was being the guinea pig for MAFS to MAP conversion and it didnt turn out as cost effective.

You could bolt on the "new" Beta head with no problems, but if you wanted to swap from MAFS to MAP, you would need new sensors, a new intake manifold, new ECU, and the wiring would be a mess.

It's not worth it.

well i'm not talking bout the head itself. i meant the whole new beta engine itself along with the ecu. maybe i wasn't clear enough on that lol.

i've read that the new betas do not have HLA's and also have MAP sensors. Does anyone know if the new alpha motor (1.6L DOHC) has HLA's, or has it switched to shims too? Thinking there might be a correlation between the MAP sensor and not having HLA's...<img src=icon_smile_question.gif border=0 align=middle>

No, you can swap the heads with no problems. They engine won't know the difference. It'll be a PITA if you try to swap sensors.
