1g-fe / 1g-ge

[Rcubed]

its still not a generalisable statement F vs G

i don't even understand what ur trying to say. is 'generalisable ' an english word?
none of my posts made any mention of performance. just the physical difference of the two engines. all of which can be seen in a parts catalog

[Karma Supra]

you are correct especially as the 1G-FE had at least 13 years more development. the 1G-GE ceased production in the early '90s

Are you not confusing the FE with the UFE?

What he's saying is that generally the Toyota G heads are the performance-oriented ones, and the F heads are the economy ones.
However, that is changing as Toyota is slowly realising that the narrow-angle heads are a better thing. For example, there are certain supposedly 'ecomony' F heads that's much better than the G performance heads with respect to potential for power output.

also that the comment on siamesed ports can not be generalised accross F heads

my 1uz F ports look the same as any G port ive peered down

thanks Bill. i accept what ur saying [and if that's Ed's intent too] in terms of performance. but that wasn't mentioned.

the 1g-g has 12 inlet runners and the 1g-f [in an Altezza and i assume an IS200] has 6 [common port to two valves]. therefore they are not interchangeable.
i haven't checked whether the exhaust manifolds are the same, but both are 6 port.
prior to that wide vs narrow head [which implies different pistons], scissor gears - different cam belt, different water pumps. none of those statements is generalised and are quite specific to the differences.

[Rcubed]

G means twin cams each driven by the cambelt and wide angle between the valves. F means narrow angle between valves [and therefore cams] and the exhaust is gear driven from the inlet cam. because the different valve angles the pistons are different.
inlets are differnt as the F has siamesed ports and the G has individual runners.

alright, i've re-read my quote above. the last statement is NOT general but refers to the 1G. i thought that seeing this thread was about the 1G that was understood. i obviously didn't expect that interpretation and have amended.

is 'generalisable ' an english word?

well, it appears to atleast be an american word...

gen·er·al·ize (jnr--lz)

v. gen·er·al·ized, gen·er·al·iz·ing, gen·er·al·iz·es

gener·al·iza·ble adj.
gener·al·izer n.

British, gen‧er‧al‧ise

Apparently "pedantic" is an english word as well! Who'd have thought!

[Bullfrog]

Just a general question if thats alright


Any chance of getting the waterpump pics reposted or emailing them to me please.

according to MOS
the 1ggte manifolds cannot be used on the 1gfe motor
something to do with the spacing

thanks Mos
although i thought putting a 1g-gte motor in an is200 was illegal ( rego etc )

[SIKTOY]

has 6 [common port to two valves]. therefore they are not interchangeable.

the 1ggze inlet only has 6 runners and bolts up to the gte

1GGTE exhaust manifold WILL fit on a non VVTi 1GFE.

[Kedderz]

Just to confirm that pistons/rods are interchangeable between the 1ggte and 1gfe?
