I seen so many posts on the swap I can't figure out what VAF to use.<p>I'll be swapping in a KLZE in 2 weeks time and I would like to know if I can use my K8 VAF which has JE50 written on it. Will anything go wrong as I have seen posts saying this causes a CEL for "too rich too lean"?<p>If the JE50 is not right which one do I need to use?<p>thanks.....

I'm swaping over the forth and plan on using my K8 VAF. Good luck with your swap.

the JE50 (mx-3 GS stock) is what comes on a KLZE in japan.

thanks for the quick replies! That crosses one more unknown off my list.<p>Just so everyone knows I managed to get a KLZE (MS8) at Foreign Engines in Lynnwood, WA for US$849 - they had 3 other KLZE's there on Tuesday - all straight necks though - all looked very clean and the compression tag were good and high and even on them all. So with duties & freight I paid CAD$1400 delivered to my garage in Vancouver, BC. I asked about freight to the East and they reckon US$200 pretty much covers anywhere in the US, for Canadians you're on your own from the border!

The thing that will determine wich VAF you need isn't the engine..<p>It's the ECU! if you plan to run a KL03 ECU then you need a KL02 VAF. If you're keeping the K8 ecu. You need the OEM VAF JE50. You know your engine will suck gas as a cow suck milk?? It will also have, when closed loop MAP, a period that the 2.5L will run lean and will overheat??? Plan on swapping a 2.5L ECU or a new burned chip with 2.5L fuel MAP.<p>I would consider for a KLZE ECU wich keep the JE50 VAF and you'll get a better gas millage as well.<p>Good luck

Thanks for the advice - how much should I pay for an ECU to suit?

goto the buyer/seller feedback forum and look for Lazzie. He can get u one. Nt sure on the price, but I know it should be <300 bucks.

Engine land for 200 CND...and it's not far from Trois-Riviere either..I'm ordering mine there

Oh made a mistake I tought the guy who wanted the ecu was from trois-riviere...Well engineland is located in Montreal (Quebec)...As far as I know it's the cheapest place to buy it.

Wow, glad I saw this post b/c i was about to ask this question just now.<p>SO let me get this straight, with the KLZE motor, you can run 3 different ECU's: K8, KL, and KLZE. And two different VAF's: K8 and KL<p>So the KLZE VAF is the same exact one as the K8?<p>So...that would mean, to run a KLZE properly with a K8 ECU you'd need a KL VAF (to get better gas mileage/performance), and if you run a KLZE with a KLZE ecu, you'd need the K8 VAF right?<p>Which would also lead me to assume, if for some reason you run your KLZE with a probe or mx6 KL ecu, you'd want the KL VAF with it to have it run properly.

actually you can run the kf ecu too... but yes
ECU/VAF
k8/k8
k8/klde
klde/klde
klde/k8(don't do this)
klze/k8
klze/klde(don't do this either)
kfze/k8

Just to add to the confusion -
I could NOT get the engine to operate correctly with either the K8 ECU or the KL ECU and the K8 VAF on a KL.
The only VAF that would work correctly was the KL VAF with either ECU.

SI,<p>so theres a place in lynwood that has ZE's for sale? that is so awesome! if i read your post correctly, they should have 2 more KLZE's with straight-neck IM's for around $850? e-mail me.
