1nz-fe intake manifold , Xa ...

[blacksandiegovitz]

Been looking for more performance from the yaris as I have all the basic bolt-on parts . Been searching scion life and found that Weapon R make a very nice intake manifold that fits the 1nz-fe that found in the Xa . I know it will match the head ports and bolts but will probaly need modify the intake as it changes the angle and not sure of the differnce from the Xa tb bolt pattern and the yaris Tb bolt pattern .

[jinxor]

they look nice... So this will replace the stock plastic ones we have on the yaris, right?

[PHXDEMON]

I think they only made a couple and scrapped it IIRC but other than the angle of the TB it should work.

[PHXDEMON]

I'm not 100% sure if the angle of the TB is even an issue actually.

[cali yaris]

^ correct, not directly compatible without modification.

[eTiMaGo]

with good metalworking knowledge/a good fabricator, one could quite easily chop off their TB flange and weld on one suited for ours...

I'm not sure these would give as much gains as the legendary magical elusive Holderner IM, but at least it's actually available, which is always a plus...

[Nexus1155]

maybe its just me but does the welds look kinda crappy?

:-/ It may be excessive but they are good welds.

[m911gt]

i'm wondering why weapon-r chose to go with two sections of pipe welded together rather than bending a single pipe. i'm sure the radius isn't too small to bend, since it's often done.

[mrbond]

Those welds are outta control. They may be technically good, but they just look awful. I'm comparing these welds to those of Fujitsubo and TRD items, though. Geez.

[at3GG]

so should a good mufffler place be able to make this fit?

[Nexus1155]

I think the weapon R ones were done by hand while others were machines?

But it was welded in two pieces because think of it. You make the box itself, then you weld the first section of pipes on, go to the intake flange weld the second, then join them together. It's alot easier to mockup like that for the person who is doing them vs. needing a jig/clamps etc to have one whole piece.

Even a couple of holdeners welds were in seperate sections?

[eTiMaGo]

holdener had them in separate sections to make the prototype easier to work on, yeah. Like you mentioned, they probably did each half separately then joined them. I'm no welder but I can imagine it's not easy to get into the tight space on the inside of the bend...

This product will be in stock on Friday 25 December, 2009. :frown:

+1. TIG isn't easy. It takes a while to make beautiful welds.

[ztrack157]

TIG is simple for me yet it took about 3 years of practice to get it right. They originally made an intake with straight runners to a box and it didn't yield any gain this is there new attempt.

[Nexus1155]

yeah the one that goes straight to the box would never yield gains in something like this, you need to calculate the runner length which is probably what they didnt do the first time around, it takes alot of physics to get these things right! lol

^^ So true ! They also incorporated Velocity stacks inside the plenum of the manifold .

So you'll take visually pleasing over quality? Interesting.

Good luck with that.

[cee_dub2003]

I have seen the WR manifold in person and the welds are good.

Yeah there products are legit . This manifold will not be avalible to purchase till december and hopefully by then the Microimage smim will be done :thumbup:

[Bluevitz-rs]

Anyone fallow up on this?

[blacksandiegovitz]

I haven't heard or seen anybody on here buy/install one of the weapon r manifolds yet . I did just buy a custom manifold set up for direct port nitrous though ...

[hondakiller99]

i actually called weapon r.. they stopped production on the piece because the demand wasnt high enough.. they gentleman also said that there might be issues on the yaris cuz they never tested it, idk maybe someone can clear it up for you guys about that?

[cee_dub2003]

The WR manifold is in stock, and the only reason it might not work on all yaris is that the throttle body is different.

[cali yaris]

Throttle body angle and number of bolts is different. You'd have to fabricate an adaptor or new flange.

[Yarisaur]

couldnt we just use the xb throttle body, and swap the electronic components??, I read the xb guys are swaping the 1ZZ-FE throttle body on to the manifolds.. isnt that the same throttle body swap for the yaris?? correct me if im wrong? but i think this can be made to work on our cars with little to no modification..

[Yoda]

i think the xb TB is not DBW

[YarisPR]

In my case making a flange for adapting the manifold and the TB shouldn't be that hard, I can get someone to do it pretty fast. People here are adapting the Corolla (1.8) stock manifold (I believe its from 1999, witch it metal not plastic) to echos. Still haven't seen any dyno results... :thumbdown:

But I have NO money at this moment :laugh:

Ain't that a BITCH? lol

I hate it when I run out of money:tongue:

What about the old version of the yaris which is DBC. What mods are needed to fit the echo version?

Should be the same,no mods needed.
