turbo and na MAF

i need a new MAF for my s5 GXL, but the MAF for the turbo2 is way more common.
can i use the turbo2 MAF or does it have to be the MAF?
the dealer has different part numbers for the two... but...

might run a little leaner. n/a maf is way more common as turbos are rare. find someone doing a turbo swap and pick up their old one for dirt cheap.

The voltage scales are different. Your engine is not worth the risks involved with tweaking fuel and timing calculations in random ways. As mentioned, there were a lot more S5 NAs produced than S5 turbos here in the US.

how do you know your TPS is broken ?

and ... I'm with SirCygnus, you are a broke college student, you should be driving Civics. not RX7

For ur original question, yes its 2 part numbers, but its just the bracket and a "slightly" shorter wire for the turbo.

you can buy NA tps for cheap, maybe 30-50 bux ?

but do they work? most likely yes. I bought a new one because I don't want to spend time to check.

This got off track... I have a s5 n/a maf if you want to buy it. I have 2 of them I'll ship you. There junk to me, but still work. I'm running haltech. If your aren't turbo don't buy a n370 maf. Get N350. Being broke you can still get by..

Oh yeah, Also have a spare S5 tps, as well.

What is your car doing? Why do you think you need a maf?

its surging at idle, ive eliminated vacum leaks with new gaskets, hoses, injector seals, and then tested twice, adjusted TB fast idle, thermowax and TPS, bypassed the fuel pump resistor relay with jumper wires, cleaned out and tested the BAC. I did change the stck airbox to a cone filter and heat closeout but doubt that would cause this
you name it ive probably done it.
and my MAF fails resistance tests via FSM.

to be honest, there is no way to tell.

not trying to judge your diagnostic ability, but it could be out of spec and you don't even know it.

try to see if someone local willing to swap the MAF with you at a local meet, then you will know if that's the cause (MAF)

its a quick swap job anyway.

does THIS not tell you everything. you need a new s5 n/a AFM, i would also test the AFM(not MAF) while pushing the plunger in and seeing how erratic the scale is, if it Fails ANY FSM test, replace the sensor.

And to answer.. Your question, Yes a n370 will run a n/a s5. if you need to move the car or just use it while waiting on a new n350. I had to run a turbo AFM on my 90 vert for about 3 weeks. after my oiginal AFM seized up(water damage). don't drive it hard, but you would be fine.

I also didn't read where the ****(pardon my french) he said he needed a TPS.
