and it will throw lean codes...
thats why when its not siting at a show, the long line is put
back on from the can to the intake. And it still throws lean
codes. PCV blowby is calculated in the PCM and figured into
air/fuel based on engine RPM, well not trully calculated, but
pre determined values are programmed into the PCM for any
given engine RPM. Sometimes even with just the catch can in
line, you can get a lean/rich code if there is any kind of long
term hard driving (i.e. a day at the track).Not to mention this setup
also creates a little more drag on piston movement due to
increased pressure (the vacuum actually helps this
movement too). Another thing it will do is create larger oil
deposit when under high load (the engine) and enough
pressure is built up and it gets forced through the "PCV
Breather Hose" (the one from the valve cover to the intake tube).
here's how Toyota explains it..

GOTHBOX:
If you happen to be reading this..
I know I explained to you how to make this PCV setup, but after
long term "testing" and reconfiguring I have decided that this mod,
breather or not, just isn't worth the side effects. It has all become
merely for show. Actually if you pop my hood right now, you'll see
the factoery line back on.


(didn't mean to thread jack..)

 

bro your engine bay is really nice can u send me more pics and mods u did?

 

lol ok so what does that mean? I might have problems if I buy the tbs

 

no, it was a different conversation about my engine bay pic, PCV set up.. nothing to do with TBS

 

oh ok gotcha

 

I'm an 06 xA owner and I was actually wondering about getting this for my car as I have a Injen SRI and an Optima battery. The battery mounting pointing point for the intake is rather stretched so I thought about getting a TBS to help this. I wanted to know what it did performance wise and that's how I got here. This thread didn't really answer my questions though so I did further inquiries and came across this article directed from a fellow xa owner.

Now, although even a 1% increase in performance would've been perfectly suitable to me, according to their tests they actually lose performance. That alone causes me to steer away from the product.

 

[quote="street_TSE_lethal"]eh, screw it, its already on there, and mine actually runs better with it like that. go figure.

(back on topic now)

 

I dont know if it has something to do with 4 cylinders vs a v8 but I have one in my v8 bronco and I noticed nothing and was a waste of $110......

 

already too much power to notice any tiny improvement???

 

[quote="Gothbox"]mine ran a little better too, until the CEL came on (and it starts running in closed loop). At first the CEL would take forever to pop on, but evry time it came back sooner and sooner, so i just unplugged it.. good luck!!

 

juz install obx TB spacer today,feel good,esp >3000rpm......fast
and sound good from the engine

 

yeah , intake growls now on hard accell... love that

 

I just recently installed a TB spacer on my tC. My engines intake always had made a faint whistle under acceleration, after my CAI was installed it got even louder. Now with the spacer installed the whistle is very noticeable...is that fairly loud whistle under acceleration normal or did I do something wrong?

 

^^^thats normal.. still may come down to the CAI design, but
the overall noise level rises with the spacer..

UPDATE:
the CAI in the box was pushed over when the TB spacer was
installed, 2 months later the mounts finally gave into the
pressure, and broke off. This is only a problem (I could
imagine) with the CAI's that have the "loop" design, like the
Fujita and Bomz, etc.,. Shouldn't be a problem for short
rams. I am switching to a CAI with a straight pipe off the TB
to the inside of the bumper. I will be cutting this new CAI
down, so the filter sits at my vented fog light cover. Should
solve the "push over" problem anyways.

where can i get the OBX throttle spacer or what
other companies make them besides OBX??

 

Im glad to see the OBX product getting good feedback. I had one of these on my Ford 2.0 Zetec and noticed a difference. I will be purchasing this sooner or later

 

Ater reading all the info on the OBX spacer makes me want one how long did it take to install?

 

I think you only have to remove four bolts and the spacer comes with new longer bolts. The only snag may be adjusting the CAI

 

wow this is going again!!!
As far as i know there are three diff ones for the 1nzfe motor
I have sold/installed 5 of them and still swear i can tell the diff in the lower end rpm's the one BlackBox06 has he bought from me. Its from
1) Design Chaos- made by a member on here you can search here for his name. it has helical cuts to compress air.

don't know if he still will/or makes them the were 75-80 shipped
mailto:aceprecisionmv@hotmail.com

2) made by Design Chaos for an E-bayer w/nothing inside (smooth?)
dont see anythng that would improve

And currently the OBX made more like other TBS's I've seen kinda like a bolt/nut thread i don't think this would create as much added pressure as the helical cuts but who knows. to date I've heard of no proof posted in the form of dyno sheets.or bench flow tests. on our cars. there is plenty of proof that this works on Carborated cars but not so much on FI cars


Here is the thread i started about them on club xb in Oct 06
http://www.clubxb.com/forums/f28/5049-tbs-box/
one member who completely dissed them called Victor out, was given a free one and never preformed the "my friend has a dyno" test for all to see.
will we ever know???

 

I know I have a tC and this isn't a forum for me but, despite what the dyno graphs show I did notice a slight difference in performance. Not sure how it is affecting gas mileage yet. I know on my car it was and easy install. Took longer to get my intake off and disconnect wire connections to move things than the actual spacer install did. Plus with a CAI is sounds pretty kick a$$. I say get one. I have the OBX which was purchased off of ebay. So far so good. Just my $0.02.
