Turbo BS Thread

By any chance, @MrCrowntown do you know the flow rate for the OEM injectors for us?
I'm pretty sure I've got a bum injector since the misfire is still present, and feeling like an injector. (Missing at idle, and misses hard when leaving idle, but drives mostly fine- even in boost. Seems to happen especially if I sit at a light or stop for a min or two)

I see Five0Motorsport has some OEM and upgraded ones, but I wanna know how much larger the 450cc's would be over stock, and if I'd throw a CEL from trying to pull too much fuel.
I messaged them just now to see if they knew the flow rate, but even Google searches came up with nothing.

 

This was discussed a few months ago. I'm pretty sure it was in this thread, but I can't find the post. I want to say that they're 300-some odd cc.

 

According to the 05 FSM (https://www.customtacos.com/tech.ol.../06toyrm/06toypdf/06rmsrc/rm2006ta/010001.pdf, scroll down to page 5), the injectors are good if they flow 284-344 cc/min. If you assume the rated flow is the median of those values, the injectors would be 314 cc/min.

 

Thank you sir! I was just looking through the manual I had saved previously, you just beat me to it!
Five0 makes some 380's that are enticing, especially since they make PNP adapters for the different pigtail types...hmmm

 

Yeah I know.

I bought an 4.0L send gen. I’ve been looking at some performance stuff for the 1GR. Those roost factor y-pipes look pretty sic

 

...

 

Yes. Yes!!!

 

U in the market for a place in north Alabama?

 

I trimmed out 550cc with a piggyback. It’s about 2x my stock injector flow.

 

Sold my hotside, going to a new owner in WY. Pretty awesome cause he owns a urd Sc tacoma with a built block. Says he’ll be using it on an xrunner. He’s not on the forum but told him to make an account.

 

That is terrific! Congrats on the sell. Quite curious to see his build.

 

Is it possible to use the narrowband from a plx wideband to replace the stock o2 on a 2tr?

 

I did this on my 3RZ. It was a '98 though before they changed the OEM sensors on these trucks.
Anyhow, I just used the supplied grey wire and ran it from the PLX AFR Module to the stock ecu. You just de-pin the O2 sensor wire at the ecu plug and re-pin it with the grey wire that is running from the AFR module. Mine started right up. Like I said though, I'm not familiar with the type of sensor the 2tr uses and the ecu pin-out for that specific application.

 

So it would be the white wire ox1b?

 

That would be my guess. On my truck is was a white wire as well. It was labeled OX1 on the ecu pin-out I used.

 

That's your downstream sensor that monitors your cat. FYI. Might still get a cel if you bypass it.

 

Maybe I'm just missing somethin here, but why would you want to use a PLX wideband as sensor 2? Is it because you have a bad stock one and have this one laying around? Or for more monitoring purposes?

I'd just as soon get the URD rear O2 sim. But then again my small mind probably isn't understanding your purpose

 

WHen I did it, I used it for my pre-cat sensor. This way I didn't have to mount a 2nd sensor

 

Thats my goal
