btw... they both are exactly the same electronics.. they are the same exact thing.. only the camry afm has a larger intake opening/exit, and a larger door. it just needs to be adjusted so that the ecu knows how much air is going into the engine, so it can lean or richen the fuel ratio accordingly.. thats a big part of the fuel injection system.

just a 22re

so if we figure out how to adjust it to work right then we all should be fine then with a lil bit more air then normal but im back in milwaukee now so im going to go and try this with my truck a 22re but i have a air/furl ratio gauge in my truck so i can tell if its running any differnt ill keep you guys posted as i should beable to go and get to the yard sometime today as im getting a tat done and alot of other things aswell but if i get around to it ill get a video of the gauge and how the ecu acts with the new mafm installed

if i dont do it today it will be getting done this week im sure

With this new vafm, Is the throttle body really gonna get any more air? It's the same size, It dosent matter if the vafm has a 10" opening....the throttle body still only has a 3" opening...The only thing I could really see changing is the fuel mixture. Hope I'm wrong tho...more power/better mileage without ruining my motor would be sweet.

unclip the top of your airbox and take a look inside at the rectangular opening/door of your AFM... the area is WAAAY smaller than the throttle body's area.. the camry AFM would match the throttle body on our trucks almost perfectly.. besides, the donor camry would have a 3.0L 3vzfe.. so if it has a larger AFM then i would expect to see performance gains since the camry 3vzfe is almost the same engine, has more horsepower, and gets better mpg (thanks to more valves, larger AFM, etc.)

Jcm you said it man. I would love to see someone try to disassemble the vafm and swap it into the new one those things are touchy with the spring and weight.

As far as the throttle body I doubt it is pulling as much as it can in the stock configuration, but you could always take it to the machine shop and add a few mm to it.

Just a thought, and ive seen a few threads started on this but none completed. Does anyone know if someone has successfully swapped the 24v heads of the camry into our 3vz?

Yes however it requires a LOT of work.... do some searches and youll find a MASSIVE thread about it that spans about 3 years.

This is a link to alot of info

I'm still reading, but though I'd make it easier for everyone else.

Its wouldn`t be that hard to swap the electronics, but from what ive been reading there the same and don`t need to be swapped. You can how ever remove the plastic cover on the AFM and make adjustments to richen the fuel mixture. you can find more information on this at www.downeyoff-road.com .

the easiest A/F compensation would be to just up the fuel pressure a bit. Adjustable fuel pressure regulators are easy to hook up and cheap to buy.

Same Injector Pulse Width + higher fuel pressure = richer A/F ratio (without ECM intervention)

you could also achieve the same thing with bigger injectors, but you'd still need the adjustable fuel pressure regulator to tune it. Supra Turbo 7MGTE might work, for the most part Toyota used the same physical size injectors on most of the models, but the flow rates differed. you can identify the injector by its color - "Witch Hunter" Injector Flow Rates - first you need to know what resistance your stock injectors are (ohms), you can use higher resistance injectors that stock, lower resistance injectors may damage the ECU injector drivers (excess current flow) unless you use an injector resistor (we already have injector resistors from factory, but may need to add more to compensate for a low ohm injector)

sounds good but more than I would like to do. Im lookin for a camry for mine to try it out. Ill keep you posted.

I'd like to confirm that the donor car should be a 91 Camry. I've seen much posted elsewhere on the 92-93 Camry/ES300. Can anyone confirm?

swaycleveland

yeah id like to confirm also. im gonna pick one up tomorrow!

just a 22re

ok so what year does it have to be then cause if im goin gto the yard tomorrow to check this out on a 22re then i would need a lil bit of info as i have a yard with with a V6 and a 4cly in it right now ones a 91 and the other a 92 and the other 3 are 93,94s lol

im going to the yard tomorrow! there is a coouple 4 and 6 cycl camrys there in the 90 91 92 93 94 vintage. there is also a couple 3.0 runners there so ill do the work and see which year and make sure the connections work i cwont have dyno figures, cause i dont have acess to one. however ill be sure to give you guys something to go on either way!

swaycleveland

ok ! well after a quick stop over at my junkyard i pull a afm off a 91 6cyc camry it doesnt DOESNT fit really well on the air clean froma 3.0 it can be made to fit but here the important part................. it doesnt work! the car wouldnt start! so it must be from a 4cycl or something else cause this on doesnt do it unless i got some odd-ball afm

blueyoda

Not to burst the bubble here but I think I remember a thread about the stock afm being able to flow the max physical demands of the 3.0. It was some eally techie engineer stuff.

wardriver

The 91 Camry had a 2.5L V6 - The 92/93 however came with a 3.0L 3VZFE.

Again - I'd like to confirm original year of the donor car preferably by VIN.

Buller.....Buller.....
