185->200hp 3vz-fe

[12340987]

So according to wikipedia Toyota detuned the 3vzfe until 1994, when it magically became a 200hp engine. Did they achieve this by enriching through the AFM and retarding timing?

I'm just wondering if these AFM flap springs get weak over time, like I read on some post here, and that leaning the mixture only incidentally improves performance. Or is that what that cog does; stiffen the spring?

not sure what the factory is doin to up the power but heres a link to some free...ish mods that will increase the hp on the 3vz.

Take information off wikipedia with a grain of salt. Keep in mind that ANYONE can write and edit things on it.

Is that what a 180hp-ish (from factory) engine feels like? My uncle has one, i learnt in it and it didn't seem that fast. Then again, i was learning meaning i was a lot gentler with my right foot. Btw, this is compared to my gen 2 Camry 2L m/t with an engine that only has about 113hp from factory.

3VZFE application in 3rd camry
92~93 camry in north america take use of 3VZFE
Others manufactured outside north america still equipt with 3VZFE. I just know the spec&feature is correct in north america but never see the formal spec&feature annouced in other area.

If the 94+ 3VZFE rated 200hp from original factory. I believe the ability of 3VZFE is great and strong engine. Maybe factory have the upgraded ECU tuning or some different mechanic fine tune in 94+ one. Nobody know the original factory howto do it.
