4ac Intake Shared With Other Engines

[mikey_m]

Hi Guys

 

Does anyone know what if any other engines share the same intake manifold pattern as the 4AC.

 

Wether it be datsun engines, other Toyota ones etc.....

 

Thanks

Mike

what are you trying to do?

 

ive never heard of any suiting...

 

there where some EFI 4ae's released which had the same single cam head. not in aus unfortunately.

 

if you going for twin carbs a custom manifold is must.

 

if your wanting a carb upgrade, best bang for buck is probaly a 32/36 weber. adapter plate to suit the standard manifold are $50 from ebay.. easily install in an afternoon.

I Have twin 40mm carbs to mount, I thought if another engine shared the same pattern that a vendor may make an existing manifold to suit. So far it is custom, it is no biggies, just more $$ and plenty of time, if I could just buy one, much easier

twin sidedraft mani for 4ac, the ONLY one i have seen for sale, there are some rare HKS manifolds but yeah, this is the only one i seen thats been sold.

Doh, I did not even see it, your post did not automatically e-mail me.

 

I am Sooooo Dissapointed I missed it.

 

I now have my flanges, just need to join them..... :)

[tas_ae71]

:bash: :yes:

 

Success byt the looks of it, I contacted the seller and he can source me another, a little bit more in the $$$$ but I have one.

Oooh, I'd like to hear any more details you find tas, have tried unsuccessfully to find AE71 extractors

[mikey_m]

Guys

 

I have been looking for extractors too, however there is bad news by the looks of it. I have been searching under many rocks and most if not all manufacturers have stopped producing beloved extractors for the 4AC... :bash:

 

I am having to get mine custom, now custom can be expensive and sometime it is not, the 4AC is an easy one to design up and if like me you want mild steel ones, then they will be cheap, however in stainless expect to pay $$$.

 

If anyone happens to know of a smaller vendor still making them, please let us all know, but by the looks of it we will just have to make our own.

might have to buy a pipe bender and do a run of them.. whos keen?

[Philbo]

Oops, sorry Tas, didn't see that post. A mate of mine said I can use their pipe bender, so I'm gonna have a crack at making some myself. As far as I'm concerned, I couldn't really make it any worse than the factory exhaust, right? :fuzz:

I'll get someone to laser cut a copy of the exhaust flanges in some 12mm steel plate, and buy some pipes/collectors.

I might take some pics too if anyone's interested, and if they turn out half decent.

[tas_ae71]

yeah id like too see when your done..

 

yes it is possible to make them worse than factory :yes:

 

take it slow, put some thought into it.. don't forget to make sure it clears everything

 

check twice cut once :no2:
