Talk:Toyota ZZ engine

Untitled

I would like to know where this info have been taken...

The output of the supposed 1ZZ-FED is not because of the engine itself, but because of the better Exhaust manifold fuond on the celica and more agressive/less economic air-fuel ratio in the comupter

Also the fact about the 1ZZ-FE using a cast aluminum intake manifold... That was on older '98 '99 corolla with the old 1ZZ-FE

I Think that the 1ZZ-FE was the one found on '98-99 Corolla and the 1ZZ-FED (still called 1ZZ-FE by toyota on their website because it's only an improvement and not a new motor) was an improved one for 2000+ model including celica and later the matrix etc...

_______________________________________

I belive the Toyota Corolla uses the 1ZZ-FE engine not the 1ZZ-FED engine. This is both because I own a 2004 Corolla and remember the out put being quoted at 130hp as well as the Toyota_Corolla page states this as the engine used. -Bryansix

I think you're right, I'll correct it. Krupo

Can it be confirmed that the 2ZZ-GE engine does indeed have a 11.5 : 1 compression ratio? I've read automotive tests of the Pontiac Vibe GT stating that the ratio was 10:1. Thanks!

I don't think the graphic depiction of the blown-up oil pump is merited for the 2ZZ-GE engine. ANY engine will break if you rev it high enough; they don't all need pictures showing what happened when somebody downshifted at the red line. Learn to brake! --Shyland 00:34, 13 January 2007 (UTC)

FED Suffix confustion

According to the list of Toyota Engine suffixes, the designation D would give it twin downdraft carbs. Is this a true suffix or just a variant of the FE?

3ZZ-FE engine is produced in Deeside, UK, as of 2002.

According to POWERTRAIN, the 3ZZ-FE engine is produced not in Japan, but in Deeside, UK. Lots of interesting details can be found in the above mentioned article (pages 20 and 21), for example about where important parts needed for the engine are produced. 89.12.58.139 20:47, 1 August 2007 (UTC)

1ZZ-FED

After @SheepEEEE72:'s edits to remove the 1ZZ-FED, I did a web search for it and I can't find anything official for it either. Plenty of forum posts asking for the difference between the 1ZZ-FE and 1ZZ-FED but nothing official. Does anybody have any idea how the -FED name started? Was it a enthusiast thing to differentiate US-built vs Japanese-built engines?  Stepho  talk  00:51, 9 October 2024 (UTC)

I can't find when it's first referenced. I also find it weird D was the letter added as well, because as noted above, Toyota used to be pretty particular about the suffix after the engine model/generation. D already had a meeting for Toyota, so why someone picked D is odd. SheepEEEE72 (talk) 19:54, 9 October 2024 (UTC)

The rumor was that the -FED had larger valves, i.e. the Celica and MR-S had the FED model. This is not true, ALL Toyota literature calls it 1ZZ-FE, there is no D in the Toyota nomenclature for this. — Preceding unsigned comment added by 69.160.36.194 (talk) 19:50, 9 October 2024 (UTC)
