klze swap questions

[windofire]

hey guys..
after alot of searching and getting more confused i've got to ask..
and some of the questions is just to verify my thougths..
my swap is going to be a ZE curved neck with JE50 vaf and KL31/36 ecu..

1 - are all the fpr's the same (k8/kf/kl)?

2 - am i supposed to use the prc selonoid?

3 - everything egr vaccum related can be blocked?

4 - under the IM (under the egr block plate) theres a hole, should i plug this or?

5 - wich ecu has the speed limiter, 31 or 36?

6 - should i swap all the sensors from my K8 to my ZE?

7 - do i have to tap a hole in the coolant neck or am i able to solder the fan plug onto the ecu sensor?

i think thats all for now..

1 - are all the fpr's the same (k8/kf/kl)?
Use the one on the ZE that you buy. Should be all the same but if it says KL on it somewhere, that will be fine

2 - am i supposed to use the prc selonoid?
I didn't. Don't know if the KL31 ecu actually uses it...

3 - everything egr vaccum related can be blocked?
Remove it all instead.

4 - under the IM (under the egr block plate) theres a hole, should i plug this or?
Block the EGR with a block off plate, there shouldn't be any other holes that go into the engine... check that you're not mistaken. Maybe post a pic of what you mean

5 - wich ecu has the speed limiter, 31 or 36?
Probably both, but as if you're going to drive over 180kmph all the time....

6 - should i swap all the sensors from my K8 to my ZE?
I wouldn't. Keep them as spares. If the ZE is in good condition, the sensors should be ok. Just keep your distributor

7 - do i have to tap a hole in the coolant neck or am i able to solder the fan plug onto the ecu sensor?
Well.... this is where many get in trouble. Answer these questions first:

What year is your car? Does your engine not have the secondary sensor in the coolant neck? Easiest solution is to get a chipped ECU that suits your wiring loom and engine combination.

Btw, when you say you're getting a curved neck ZE. Check it has KL31 cams. Anyone who says they have a ZE without KL31 cams is dreaming. It's BS and just a Millenia/Eunos800 2.5 with lower power cams.

it just seems to me that swapping over the k8 filler neck is the simple, logical thing to do

KL36 and JE50 maf is the combination you want to use, kl31 doesnt seem to run to swell idunno why. take all the egr off. useless. if your 94 youll have 2 coolant sensors, you can only hook up to one and ive read lots of debates on what sensors is the right one so idunno. but theres Black and Green. i used green and just left the black one.

[RX8SE3P]

93 has 2 sensors - One Green, One Black. A 93 ECU will look for both sensors. The Green one is the engine control sensor, the ecu will run air fuel ratios based off this etc. The black one controls the second thermo fan. What happens is the fans will come on and stay on if you don't have the black one and the ECU is looking for it.

94+ Have only 1 sensor - I believe mine is a grey one. This does the job of both. No one has fan issues if their ECU is a 94.

If you have a 94+ chipped ECU, no problem.

If you have a 93 ecu and you engine and wiring loom don't have that second sensor and connector, your thermo fans will run all the time...

it just seems to me that swapping over the k8 filler neck is the simple, logical thing to do

Maybe yes, if his K8 is a 92/93..... otherwise it will only have 1 sensor also!

KL36 and JE50 maf is the combination you want to use, kl31 doesnt seem to run to swell idunno why.

KL31 and KL36 ECU`s run identically. The KL31 & JE50 VAF combo was the choice to use for many many years and was THE sought after ECU for a time. There's no way to explain why cWs306's KL31 didn't work well except that it's just a fluke in whatever system. Both have a limiter as they come from Japan cars. Unless you can find one that was modified by Lazzyie oh so many years ago, it will be limited. Oh an I so enjoyed not having a limiter

sry guys.. forgot to tell the year of my car, wich is '92.. but thanks for taking time to answer my Q's..

1 - checked out the fpr today it read kl02.. when my curved neck arrived there was no fpr and the IM on the ze was a kf.. so i've put the kl02 fpr from the kf IM on the curve neck..

2 - that selonoid thing, would i really like to know.. i've read a post about a guy that said it did nothing, with or without..

3 - checked the egr valve today, it had a plate between it and the heads.. so ill leave egr valve on but no vaccum for it..

4 - the hole om talking about is in the IM.. its marked with a red circle in this pic and its about 20mm http://www.bilgalleri.dk/uploads_alb_la ... 3541_l.jpg

5 - the speedlimiter thing isnt the biggest thing, but would be nice not to have one if im going to drive german highways sometime (some of them has no speedlimit)..

6 - roger that RX8SE3P

7 - so the early one has 2 temp sensors in the cooling neck and the late ones have one or? so if the coolant sensor on my ze has a green and a black sensor it will mate up to my '92?

i have checked the cams, pistons tops and of course the heads.. and unfortunetely the cams does not read kl31 but kl01.. but when i get my engine running and its running good, im going to get them regrinded as coltcams performance n/a..

Nd4SpdSe - uhh.. very usefull information..

[RX8SE3P]

Yes, 92/3 engines have 2 double wire temp sensors (green and black) in the cooling neck (not including the single wire temp gauge sensor)

Ok your car is a 92, that means your wiring loom has all the connectors it needs for any coolant sensors, that is good, no extra wiring required there. If your new engine has the two sensors (NOT including the single wire sensor, that is just for your temperature gauge) then you don't need anything. Just plug them all up and you're good to go. Let me know if you don't understand what I mean and I can take a picture of my ZE for you.

Btw, sounds like you have a Millenia DE, interesting that it has a KF manifold on it.... either way, if you get colt cams it will make a big difference.

Not sure about that hole in your IM, I have a straight neck ZE and not sure wtf that is.

[windofire]

I would really like a picture of the sensors (including one of the gauge sensor), just to be shure..

The reason it had a kf intake was because it was installed in a 323f ba.. how much power did the milli DE make?
I've checked that my engine has kl31 heads and flat pistons..

And theres something about that knock sensor.. could you tell me what I'm supposed to do..?

[cWs306]

a picture of the temp sensors and fan sensors? heres the best i could do. red circle is circling both, blue circle is circling the green one i used.

[RX8SE3P]

Yep those are the two he needs.

4 - the hole om talking about is in the IM.. its marked with a red circle in this pic and its about 20mm http://www.bilgalleri.dk/uploads_alb_la ... 3541_l.jpg

Thats the port for the EGR valve on your millenia intake manifold. Just plug it with a large drain plug bolt. Sry man looks like you just have a millenia motor not a true ZE.
