4agze bigger manifold

[reecegze]

Hey guys just wondering has anyone tried to fit either the 16v bigport manifold or quad throttle bodies on the fwd 4agze.. does the supercharger need to be relocated away abit or it can be done ? i find that the 4agze stock manifold restricts flow and therefor power so if anyone has done this mod please clarify this for me please.

Yes been done before many times with the above and custom setups without moving it!

[reecegze]

ook thats good news ,, i thought you could only do it if you remove the charger.. Would you have any info on it or pics .. searched google with no luck

can you provide us with some of the many examples mick?


reece, do a search for Ben Wilson. he made himself a custom inlet manifold while retaining the s/c's factory location.
if you wanted to use a 4age inlet manifold you will need to lower the s/c approx 3" to clear the manifold.

i have tried to do this before. i was using a RWD manifold and the SC did need to be lowered by bout 3 inches. the only problem them was that the engine mount was in the way, so i didnt do that.

i am currently having a custom manifold made using the stock one and adding new runners and a new plenum. ill get some picks up soon. im also going to be using a holden v6 throttle body

here is a pic when i had the SC lowered and the RWD manifold on

Thanks 3inchs is alot of lowering , ill be interested in seeing your custom manifold
since i cant put the n/a one on. I might aswell look into some cam upgrades, any suggestion cams for a 4agze for reving good throughout rev range without sacrificing low end??

i read it as "been done many times with stock manifolds, after moving the SC... OR... you can use a custom inlet and not move the SC"

now... what about with the T3 manifold adaptor? does that move the quads up high enough?

damn i just realised i missed the part where oldcorollas has 666 rep points

He didnt, he jumped from 663 to 667 i think.

I'd be very surprised if they did. I don't have any pictures of mine, but I had to turn it a lot tighter than I like to get it through the gap.

FWIW - The 20v head fires over the top of the supercharger very nicely...

Yes thanks Stew!
Sorry reece12, i have had a foul flu the last few weeks and im not all there at the moment!

I will see if i can find you some pictures and scan them for you as i have started getting into all the Movers boxes in the garage and there is a couple somewere while loads of photos , only taken a year and a half to get into the boxes!hahahah.

sweet thanks

The T3 manifold puts the quads directly inline with the ports, completely horizontal. Also it mounts the quads upside down, which is optimal but places the throttle cable at the bottom which is sure to foul on the SC if the quads themselves dont. Hell even the water pipe going back only just fits in.

Yep - thats why I sold my t3 manifold. There was no way that it was going to fit on the AW11 with the supercharger in there.

The 20v head (with itbs) will fit quite nicely with the supercharger in the stock location. Looks pretty neat too. For the cost that you can find a 20v head these days it's well worth considering for a swap. It would be marginally more expensive than just buying the 20v throttles without getting a manifold to mount them on the head.

hey chris

they redesigned it for more dangle of the angle, now they face upwards like all the other hot jap ones.




i'd go back to NA for such hot alloy billetness, nah maybe not, boost is best
