Teg,
I saw the MR2's brouche and a little picture is showing the engine with something like a Timing Chain. I am wondering is it really a timing chain in MR2? if it is, does timing chain require replacement like the timing belt?
I know a tread has mentioned about this, but I hope you don't mind ansering it one more time!
Open deck, die-cast aluminum block with cast iron cylinder liners
Full size main bearing girdle with cast iron bearing caps
Laser clad valve seats (read "very thin") allow larger
intake and exhaust valves.
10:1 CR, "generous tapered squish area", runs on 87 octane (US).
Intake in front, exhaust in back, intake manifold apparently tuned
for low & midrange power. Exhaust manifold very short 4-into-1.
77 pounds (27%) lighter than 7A-FE
Originally designed as a gasoline direct-injection engine
Sequential multiport fuel injection
Direct Ignition System
Uses a timing chain.

Huh? Isn't the engine with the VVTL-i larger than the VVT-i one? The 140hp 1.8L Celica engine is something like 2cc smaller than the 180hp 1.8L Celica engine.
Ah, yes, you are correct, the 2ZZ-GE is 2cc bigger than the 1ZZ-FE. I mixed them up.
If anyone cares, the 2ZZ-GE's bore x stroke is 82mm x 85mm.
