Fuel Regulator - SVT & BT

[levin818]

I have search thro' the net and found that all info from the blogs and forum stated that SVT and BT's is sharing same fuel regulator, that is 23280-16140. In fact, this is misleading.

The fuel regulator use for SVT and BT are actually different in shape and part number.
SVT's - 23280-16140
BT's - 23280-16160

However, i have never test out the pressure. Perhaps some one can input?

Ah ha...Good info...

and I believed some of them notice that SVT's FR was infact a bit bigger...
so they decide...

"hey...SVT FR much more bigger...bigger means more power...let use that one..." eqeqeqqqeq...

but then ...getting the pressure range between both model would be useful info...since we're lacking of tech info... :D

BTW...in my blog, I didn't mentioned any of SVT n BT FR part number...just stated there, that 23280-16140 is interchangeable...(still using SVT FR...ignoring BT FR...hmmm...does size matters ?? )

i'm using BT regulator for my SVT (to replace AFR), i believe the pressure was the same. I'll check again the figure. In term of power/fuel save - both at the same level.

For you information, the both actuator was set the fuel pressure at 2.55 kg/cm2... Hence both are the same thing only.

But why with the different in part number... ?
It might or might not be the same...

 

[levin818]

I guess part numbar diff is because they have diff in shape.
BT's is always a cost down version from SVT's. They reduce the size of the FPR's head by removing unnecessary materials fr the SVT's. Since the body diameter is same, hence i believe both using same spring inside and deliver similar fuel pressure.

 

[chinozie]

hmmm...maybe you both right...

maybe Denso came out with similar FR out...
and cost cheaper...

who knows...

yes... because they save material, weight (maybe), and cost.

When any parts have different shape,size,dimensions,spec...usually manufacturers will give different part numbers

Knowing toyota, the newer model is probably shared for different cars as well.

My BT FR on SVT result = nearly 4 bar or 52++ psi !!
If not mistaken, last time it was 40+ psi. must be something wrong.

That's the beauty of it...
but not the engine Blocks! Toyota so rich, they made new block molding for each model...not like Honda... :D ...they shared most of the block, just changed the the cylinder wall sleeves would be enough...thus change the engine capacity...

check fuel pump conditions...
check what fuel line size are running with...
check FPR conditions...mostly due to soft rubber diagram, due to age factory..time to change perhaps...
check fuel filters...
etc etc...
