1NZ-FE Exhaust Manifold on 4AGE 16V Block, Possible w/ Minimum Effort?

[ballpencil]

I know this is a long shot.. but can anyone inform me if a 1NZ-FE (Yaris?) Exhaust Manifold will fit to a smallport 4AGE 16V with minimum effort?

Reason i'm asking:
Got a cheap offer for 1NZ-FE turbo cast iron manifold as i'm gathering parts to turbo my smallport.

This is the manifold

This is a sample of 4AGE Manifold

Seeing that there're 5 bolts holding the manifold, 2 upper and 3 lower, which is similar to a 4AGE got me wondering. I know there's much more to consider such as port diameter, port-to-port spacing, etc. That's why i'm asking this.

If the bolts line up, it would be easy to make an adapter to match the ports.
Of course, i can always redrill the bolt holes if necessary.

if bolt holes and ports match, use it. and let us know if it does, as that turbo placement could work on the aw11...
if they dont, get one to suit the 4age.

yes, this is exactly what i'm asking. i can't take the manifold and compare it with my engine before it's paid for.
let's see if i can get an even better price for it. i might just buy it and take the risk.

in the meantime, anyone else have a say on this matter?

[feral4mr2]

cheaper option then is to buy a yaris manifold gasket and compare it with your 4age one.

I doubt very much they'd be even close as I think the bore spacing on the 4A should be much larger than the 1NZ.
(I think)

with the pistons being 75mm vs 81mm? yeah that's what i thought too. but there's no way of being certain unless someone compared them first hand. will do the 1NZ-FE vs 4A- GE gasket comparison then. should be able to do it directly in a part shop.

Why bother when a set of extractors are what, $200?

because the 1NZ-FE manifold was offered for $50 and the extra $150 could get me a new intercooler or used TD04 turbo?
mind that i'm in Indonesia and that pricing might be different from down under.

[LeeRoy]

Ok fair enough. Why not get some second hand 4A extractors then, surely they would at most be $100.

While i'm all for trying to get away with things for minimal cost this is not one of those things. There is a good chance stud/bolt pattern will be different, as will port spacing and size, so there is decent work in fixing this up so it fits. The 1NZFE runs the exhaust on the firewall side in FWD setup, so chances are any extractors you do get will either poke frontwards in a FWD 4A setup, or towards the side of the car if your 4A is mounted north south. Then, joining the rest of the exhaust to this is extra work again.

This is not to mention the manifold is for a 1.5L engine, and if it's the stock 1NZFE manifold not only will it face the wrong way, but it's going to be almost guaranteeably worse than a stock 4A manifold due to size.

I might even have a stock 4AGE smallport exhaust manifold from my AE92 sitting in the garage and i'd be happy to sell it to you for just postage cost if it's of use. This is just the stock cast manifold.

Not trying to burst your bubble but it would be a shame to see you waste your time and money on something that has no real benefit.

Leeroy, did you miss the "turbo manifold" part? $100 second hand 4ag turbo manifold? mayeb the cheap shitty chinese ones?


and looks very compact too

[ballpencil]

hahaha.. i didn't see anything wrong with leeroy's last post as i thought he was offering me his extractors for me to compare it with the yaris turbo manifold. but now that oldcorollas mention it, it's possible that he's got the wrong message. i won't get any second hand 4A extractors though, as it would be cheaper for me to get the gasket and compare it. i'll end up using the gasket anyway.

and yes, that's the turbo manifold. made by shitty chinese Zage.. but since it's cast iron, i reckon the possibility of it cracking is less than the stainless pipe counterpart. not to mention i've seen many Fits, Swifts, Yaris running that manifold here.

[LeeRoy]

Ah my bad - sorry

[SLO-030]

Keen to see some results of the comparison.

Would also be handy for anyone wanting to RWD a 1NZ (dont know why) meaning they'd be able to use 4A extractors (given the intake and exhausts are on the same sides)

[ballpencil]

ok.. the seller was a very good guy and he helped me measure out some numbers on the manifold.. here's the comparison.
measurements were taken on the manifolds, not on the gaskets.

hope that's easy to understand..

some notes i can extract
- the lower stud holes and the upper mid one are symmetrical to each.. they're only offset to the upper left and right holes.
- 1NZ-FE actually has bigger port diameter than 4A-GE (!)

what bothers me the most is dpp and, subsequently, dp1p4. the differences are a bit much, aren't they?

what do you guys think? should i get the manifold anyway?

here's an extra bonus given by the seller. the 1NZ-FE flange.


it would be easier to check the difference if someone could make a scale diagram showing both manifold flanges.

their dimesions are slightly off, missing some or I'm just reading it wrong...

not close enough to use as a swap i'd say.
