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?

Dmitry

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

daniel_depetro

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?

javageek

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.

Bullfrog

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

Thanks!
