The problem with just changing the resistance...

You still have a 15yo AFM that's most than likely going to fail at some point given just about all of them do.

But new ones and you'll never have to worry about it for another 10-15yrs. AFM issues can often being a major pain in the ass.

I got mine done by the same people mate, havent installed them or run them yet so comment on how well they work

the way i saw it was

1. I can either go to the trouble to sell my standard ones, buy second hand z32 ones, screw around with plugs etc

2. Buy genuine nismo ones that are more then $1000 dollars as a pair from memory

Or 3 get them cleaned recalibrated and have them still looking stock and able to bolt straight back up to my apexi intake system... remember though ull need to pay for postage to send your standard ones off and get them sent back

cheers

Closer to $750 exchange rate depending

Sell old AFM's for $150 - ~$600 for brand new, high resolution AFM.

Not a bad deal if you ask me. Especially if one of your recalibrated old AFM dies... You are immediately behind in both cost and downtime for the car as you now can't use a stocker AFM to get you out of trouble

agree with r31nismoid

airflow meters can fail with age and are crucial for engine management operation

i see no reason to skimp on them when you can buy brand spanker new nismo's off the shelf readily avaiable guaranteed

Haha well that's not very comforting! Lol. May have to look into genuine nismo meters then because these re-callibrated ones are $275 or $295 each (exchange for old ones) so like you said if you can pick up a pair of genuine nismos for around $750, sell old ones for $200 you're paying the same for brand new genuine really

Go for the NEW Nismo AFM's, i was trying to put off getting them because of the cost.

But really, you have to see the benefits

1 - they fit up as stock (air box, apexi pods, etc)

2 - they're new, so they should last a good 10-15years at least

3 - they allow so much more flow to be reliably measured

My missus WRX had the engine go in it, and it was because it was running stupidly lean because the AFM wasn't reading properly and leaned the mixtures out. it cost her $7,500 for the engine and she still had to get a new AFM. the AFM was a $250 part and because it was stuffed it caused over $7k damage.

the question i asked myself is, do i really want to skimp and save a couple hundred dollars and still effectively run a 20 year old AFM or go for a brand newie and not risk having any major issues caused by the AFM's

Would go for ecu with map sensors but want to retain factory airbox etc and only looking to achieve around 300kw atw. Probably cheaper to go something like d-jetro and not worry about afm's but Unfortunatly cops up this way don't take kindly to pods or made up airbox"s etc and an R34 gtr kinda stands out on country roads lol.

You just get drama of a different kind to replace it with.

Nothing isn't without drama.

Like what?

Mine's been on map sensor based ecu's since 2 weeks after I bought it in 2005 and havnt had a problem with map sensors.

    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
    • I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
    • Is it alright to top up with just another green coolant?
