1NZ-FXE inake manifold ?

[Parmas]

I saw this 1NZFXE engine of the Pruis hybrid and it seems that the engine is similar to the 1NZFE. The only difference that is surely evident is the metal intake and the position of the throttle body (maybe also the size) .

I was thinking if someone knows more about this engine, especially if the intake mani fits the 1NZFE. If it fits... there is also to consider if its better flowed and what are the gains in terms of power and torque of this mani over ours.

It will bolt to the head not sure about clearence else where.

[eTiMaGo]

if it does bolt on, might make for some better charge pipe routing!

[thebarber]

forget the 1nzfxe manifold and just get a supercharger ;)

likely to fit on the yaris, but im unsure as to whether you'd see much in the way of gains.

etimago is right, however, it might make for some easier plumbing for turbo applications...

the reason it goes UP, i think, is beacuse on the prius, the electric motor sits on top of the transmission (to the drivers side of the engine) so there isnt the same room for an airbox, etc like the yaris has

looks like you'd also need to modify your dipstick for your yaris...

barber, look up Parmas' car, he is already turbo'ed :D

AND has a throttle cable...

is the throttle body integrated?

[Parmas]

I understand there are complications like the:

- Maybe integrated throttle body
- throttle is by cable or by wire? probably by wire
- Dipstick issue
- Intercooler piping length adjustment ( not that of an issue)

If I could find one of ebay I would check all sorts of issues on site maybe there somehing good in it...

[Parmas]

hmm Found one for $147 .... http://www.toyotapartszone.com/oem/t...101-21060.html

The 1NZ-FXE throttle body will not work with the yaris. It is drive by wire, but it's not the same as the Yaris. You'd need to make an adapter plate to fit some other TB.

You have to remember, that is 1997 tech you're looking at there in the picture.

[Parmas]

You are right the throttle body will be the problem here. Is there any other metal intake on a toyota that fits the 1NZFE?

[Bluevitz-rs]

only 1NZ and 2NZ parts fit.

It would be interesting if by minor adjustments we could fit a 2ZZ intake with a 1NZ engine (for those running standalone)

The main problem would be matching the 2ZZ intake holes with the 1NZ block holes.

Also does the throttle body is by wire or by cable?

[thebarber]

2zzge's have throttle cables..

[Parmas]

I am thinking of buying the 2ZZ-GE intake gasket for few bucks and match it with the 1NZFE port holes... This would'nt be expensive to find out.

I don't pretend this would match perfectly but if there is a few tollerance I shall give it a try...

[Bluevitz-rs]

I can absolutely guarantee it's not even close. My parent have a 2ZZ-GE powered Matrix, and I've seen it enough to know.

Your only option would be to custom fabricate a new upper portion of that manifold so it fits the 1NZ head and use the 2ZZ lower portion with the 2ZZ throttle body.

That would work.

I've though about doing that myself, I just don't have access to a mill anymore.

When you go changing around manifolds, you're likely to change the resonant frequency at which you get the optimum "ram" effect of the intake pulsations producing a positive pressure at the intake valve near closing, which gives you a bit of free "supercharging." The stock engine with the stock manifold has its torque peak at 4200 RPM, but has an amazingly flat torque curve across the whole band. You might end up getting a higher peak, but lose torque in the midrange and lose performance overall.

[ddongbap]

I think most of the flat torque curve has to do with the VVT-i.

Not ALL of em.
