MAF Selection

Post by **djtodd** » Fri Apr 04, 2003 9:12 am

Ok, I'm piecing together a turbo system and I was wondering, I've seen several people using the cobra maf. Is it neccessary? I was thinking of using a z32tt maf, will that get the job done?

Oh, I'll be running(hopefully) ~17 psi on street gas and 22-24 on race fuel. And I haven't picked out an intercooler yet so I don't know what size piping I'll be using. Any recommendations?

sounds like your setup is goin to be a lot like mine. either maf will work for you.

well with that much boost I'd suggest most deffinately an FMIC and good-sized piping. You are planning on rebuilding your bottom end, right?

as for the z32tt, I'm not really sure. My best guess would be that it would probably work, dunno about at those high boost pressures though.

Oh yeah, bought another engine to build with forged internals so I can still drive my car for the time being.

And I'm definately gonna be using an fmic, just haven't decided on which on to use yet.

I was planning on using je pistons, but I've heard a few bad things about customer service and what not. Are there any other manufacturers selling forged ka pistons? I've seen arias but that's about it.

I like Arias' high-silicon alloy....They are much more quiet than low-silicon pistons. The last thing you want is your newly built engine to sound like a diesel! :pface

This post needs some Cobra vs Z32 MAF differences!

:dunce <----Structure240SX

For those of you who are of less than average intellect (Structure240SX), I was simply reffering to the fact that this thread was intended for deciding between Z32 and Cobra MAF's, hence "MAF Selection". And that this was addressed with a bunch of "either sounds ok... I guess" replies. I was merely saying some pricing, capability issues between the two should be discussed instead of vague opinion. Get it?

:slap

matt0941 = *** + hole

just kidding man. you were right about the "should be fine replies". it was just from what i have read that it seems they both perform equally or atleast are able to get the job done with whatever amount of boost any of us would ever see. i dont know any specific differences about them other than one is ford and one is nissan.

Ford MAF is cheaper than Nissan. But it requires splicing wires, and isn't exactly plug n play. The Z32 MAF plugs right in, no questions asked. Not sure on the flow of both, but they both flow plenty.

If you want a Z32 MAF, we have a couple in stock. [email protected]

Z32 maf can be run with an AFC. Cobra needs a JWT ecu. Also, I think JWT only programs 50# and 72# injectors for the Cobra maf, and you'll need at least 50# injectors for that pressure.The intercooler piping size won't affect which maf to choose, since it's before the turbo in 95% of all setups... so your turbo is usually the deciding factor there.-Jeff

Do you mean that the Z32 is compatible with all piggyback systems (well all compliable with KA) not just the AFC? And that the cobra REQUIRES the use of a JWT upgrade with the Z32 can be used with stock ECU?

Yeah....something like that.

Post by **Maeda** » Fri Apr 04, 2003 9:12 am

yup the z32 maf works with most piggy backers... the cobra however does not...

ive been told its good to 500 HP... but i wouldnt go on that alone...

yah im looking for a new one too cuz the one i got is busted! GRR!!!

z32 is 3inches for reference...

Wow that is rough man, no wonder you couldn't figure it out.

OT: Yea I met this guy on a flight last night who OWNS a cobra and he said that he modified his MAF so it was larger or something to that extent (seems odd to me in theory) but I couldn't see why it would be necessary. Imagine using a modified Cobra MAF, capable of 600+ =)

You mean a hacked MAF? yes it can be done, though I wouldn't.

Actually I do know how a hacked MAF and that could have been what he was talking about, hmmm. I stupid.

i have a cobra mafs if anyone is interested. Comes with new 3.5" K&N filter and wiring kit from Ford to tap in into factory harness lines.

Post by **white98s14** » Fri Apr 04, 2003 9:12 am

Did you get this from JWT? How much for the MAF and Harness?

PM me if you like, or E-mail me and we can talk.

Post by **klattr1** » Fri Apr 04, 2003 9:12 am

i got it from someone that has a 93 mustang cobra and he upgraded to a bigger mafs, and injectors. It is the exact same thing that Jim Wolf uses but they put a markup on the price cuz of the demand of 240 owners.

I want to add to this thread. If you decide to use a “blow through MAF” setup I say go with the Cobra MAF. Reason why is it is made of aluminum verses the Z32 MAF is not. You can use a Z32 maf as a blow through but at high boost you can expect cracks.

Post by **d240t2** » Fri Apr 04, 2003 9:12 am

Eh...I don't see 30psi of boost cracking a Z32 MAF. We have used Z32 and S14 KA MAFS (plastic) in blow-through applications with no problems. Really...30psi is not a huge load to be putting outwards on something that is completely round. Load is spread equally on something that is round.

If you have broken Z32 MAFS in your experiences, I'd love to hear about it...but we have not, nor do we expect to.

Maybe the crack was already there.

Maybe u are all on crack.

Hey, don't knock it till you try it my friend....

Post by **95_240sx** » Fri Apr 04, 2003 9:12 am

Anyone know what MAFs that Duy or PSI240SX ran in their cars? That might be your best bet if it has worked for them before.

I ran a Cobra Maf from a mustang.

Post by **Structure240sx** » Fri Apr 04, 2003 9:12 am

If you use the blow through method will that solve stalling at idle and being rich between shifts using an atmosphric bov? i jsut picked up one and want to run it with my nsport kit. i was planning to get an safc to help with the idle.

Post by **WDRacing** » Fri Apr 04, 2003 9:12 am

I was under the impression that all MAF's can't be used as blow though, I was never able to get my stock MAF to read properly when mounted in the blow though position....Somthing about the air being compressed already...I stick with pull through, has always worked for me.
