4agze extractors on a 4ag head?

[Adams4AGTE]

This may help to ???
this is a manifold for my turbo and it fits both 16v and 20v heads... note the to end holes are slotted !!!
16v users the top part of the hole !!!! and 20v users the bottom!!

Good luck!!!!

Only true of the early bigport 4AGEs. The later bigports (and the bigport 4AGZEs I believe) are 7-rib and same size crank/pin as the smallport.

Yep my stuff up !!! All gze are 7-rib

But all the ge bigports use the smaller crank and rod's ??? not 100% i could be wrong !!!

Try here tey contradict each other ??

General consensus is that the bluetop bigports are 3-rib/18/40mm, red/blacktop bigports are 7-rib/20/42mm. Most references will back this up, the club4AG one seems to be the main odd-one-out.

So in conclusion:

You should be able to put a G head on a GZ block. Block up the injector wholes, get a manifold for your carbs and tune the fucker.

Then start on the 86!

RE: 4af:

4ag(z)e extractors do not fit on 4afe's 4afc's or 4ac heads.

So will that fit a GE head? Im guessing they are different?

[Grega]

As long as the GE head is a 16v then yes they will fit.

[Adams4AGTE]

Q... the 4a-fc and fe are different from the ge right ???

Read some where that they have different cam tooth pitch ???

[Rhyno]

Yes Adam if you have a look at how Toyota codes their engines you will see that the F stands for econermy head (or something of that description) and the G's are there sport head.

The G heads are made with a wider angle of the valves in the cylinder head.

Here is a good reference that explains it well:

F series have one timing belt gear external with the alternate cam driven by a gear inside the rocker box.....also as rhyno has stated the F is for economy as opposed to the G for performance although that is another topic for debate due to valve angle and flow characteristics.

[Rhyno]

Hey Grega,

Sounds interesting...

Is their a thread on this debate?

Sorry for jamming up your thread luke!

Hey grega

im sure it was one of your threads that i got the info form ???
and i should have been a bit cleaner in my question

so here i go
is it possible to put the F head on the G block as they are similar ???

not that i plan on doing it !!! ever but more just a need to know ???

[dangdang]

In regards to the F series block AFAIK it should be identical, the block that is not any of the the internals, can anyone confirm?

[Grega]

the F block appears to be the same as the early 3 rib............i have a G 16v small port head sitting on a 4AFC block - no problems. but yes, 18mm/40mm.
