V.a.f.

[wolfspiritky]

I have read many posts regarding using a V.A.F. from an 86-88 RX7 for better air flow and possibly increasing horse power.

Is this the sensor I need for my 91 EGT??

It is listed as a MAF. Opening day, March 30th is closing in fast.

I saw one of these for sale not that long ago. B code VAF is the RX7, then there's the U code.

What's the difference? Which one do I need?

Just post a wtb ad here. That's a lot for one.

True that.
I've seen them for sale at the j/y for under $50. You gotta look though, and no guaranties.

[wolfspiritky]

It is a reman though. I've seen them sell on ebay for more.

None to be had in any yards within reasonable distance from me.

Give Turpro's suggestion a change for a day or two and see what bubbles up. You never know.

What is the difference between the B code and U code?

How do I determine which one I need?

[1st Gen]

excuse me, B code is RX7 Y code is BP 26, or GTX

Don't we have a VAF sticky or something yet? lol question is asked enough times...

[wolfspiritky]

So, I will need the "B" code if I do what I have read, "use a VAF from an RX7"

[Mazda_Powered]

B code is the RX7 VAF.

Don't expect to feel a difference. The only thing it really does is give a 5hp difference after 6500rpms. If you're boosted it would help more

Would there be any difference in a B6?
