when you do the full swap, it has the vtcv or whatever that the altima's and maxima's have? how do u ajust the motor to the speedometer?

Who said you could use a 5.5G clutch with a 4G flywheel? Not without modification. The PP alignment pins are in different locations.

You can use a 5G clutch with a 4G flywheel.

What is so difficult about getting a timing ring/spacer made?

yevrah4728

well, my friend thats helping me with the swap got the bright idea of using a fidanza flywheel (i had it already for the the hybrid swap) problem is its the 4th gen version. i have the 3.5 timing ring(from fidanza...dont ask), i'm just befuddled as to how to mount it to the fidanza fly being that welding steel to aluminum is harder than advanced calculus....or so i've been told...

i wanted to do the motor part of the swap as quick as possible that way i can focus on the dash adapter harness. i dont want to pull my flywheel and have to send it out and wait for whomever (i have no idea who can or would do this in my area) to fab a timing ring spacer. besides a lightweight flywheel on a full swap would be badass, no?

goldtooth

iTrader: (56)

You are welding the timing ring to the spacer not the flywheel.
The spacer then bolts to the flywheel just like an A32 timing ring would.

yevrah4728

oops, i knew that. sorry, my brain is on overdrive with all of this...but who or rather what kind or company would make the spacer?

goldtooth

iTrader: (56)

WTF!!! I can't find M166 on the 02 main dash harness if my life depended on it. Neither did I see it's mating connector on the engine harness, F69. What gives? Is this something for Automatics?

eng92

iTrader: (3)

No, it is not specifiic to AT.
Do you have F55 and F68? (both white 18-pin connectors?

If not, then it sounds more like you have harnesses from a 00/01.

goldtooth

iTrader: (56)

Yup, I see F55(male), F68(female) and F49(male). and that is all that is between the firewall rubber grommet and the big ECU connector... I can take some pics later.

eng92

iTrader: (3)

You may be right about it being for AT only. I took a quick look through the EL and EC sections and I did not see any F69 connector references.

However, in the AT section, it is referenced regularly.

It certainly wouldn't be the first time an inconsistency was found in the FSM.

iTrader: (6)

So then would you need the key cylinders for the ignition, the doors, and trunk?

If so, will the door and trunk cylinders fit on the 4th gen? Or would it have to be a retro fit?

goldtooth

iTrader: (56)

Harness is nearing completion, might be in the car today if time is managed well. All components are ready to go!

Question for swapping in the '03 guage cluster into '98:
Will all the wire ends off the '03 guage cluster harness be used (spliced into the '98 guage cluster harness)? I went over the chart nismology sent me and I checked the connectors. All wires on M32 will be used, but on M33, 4 wires are not in use and on M34, 6 wires are not in use? I will double check the FSMs again later today.

PS. I think there is a typo on the chart. Ignition switch ON or START power to cluster says (98) M84 pin 37(green) to (03) M33-24(orange) and M33-50(orange). Problem is that there is no M33 with pin #50 it only goes up to pin #24 on M33. It is either M34 pin 50 which just so happens to be orange as well... or M33 pin 5 which is orange as well??

Question regarding AFPR: Do I need one? If so, which one is the best and where to get it?

nismology

iTrader: (8)

My spreadsheet assumes '99 wiring. Some things may be different with other years.

goldtooth

iTrader: (56)

Well, looking at the pinout that IS on your spreadsheet, leads me to believe that there is still a typo?

nismology

iTrader: (8)

Oops, my bad. Yea at this point I don't really remember why I put that there. Looking into it...

hacim105

iTrader: (6)

Is this full swap going the same route of eng92 and still partially using the A32 ecu or will this swap be using the A33B ecu only?

I'm having a hard time finding an engine that is relatively cheap. There is one I found for $700 with 43k miles on it. Does this sound reasonable or should I keep looking.

Jime

iTrader: (10)

Eng92 and myself are using the A33B ECU only.

hacim105

iTrader: (6)

then I must have read his thread wrong about using the A33B ecu. I thought it said he used the A32 ecu for some functions but obviously I didn't read very carefully.

hacim105

iTrader: (6)

A couple other questions

Is it necessary to have the ECU be from the same car the immobilizer and key? If the ECU wasn't from the same car what complications would I run into?

Also when getting a gauge cluster, do I have to use a Manual gauge cluster since I'm manual? If not, are there cons or complications I'd run into using an automatic gauge cluster?

And does it matter if the axles come from an auto or manual?

nismology

iTrader: (8)

No. As for complications, you'd have to get the car towed to the dealer to have the new ECU programmed. You'd also have to pray that the lack of ECU programming is the ONLY reason the car wouldn't start.

It doesn't matter. The PRND21 thing in the middle would be annoying for me, personally.

Axles have nothing to do with the ECU. It's the tranny you're using that counts.

goldtooth

iTrader: (56)

Damn, I had the spacer made, but the timing gear is too big for the spacer, wtf?! pics in a bit

was I sold the "wrong" 3.5 timing gear?

goldtooth

iTrader: (56)

eng92

iTrader: (3)

The spacer is designed to be used with a weld-on timing ring.
That timing ring is intended for use in a bolt-on application.

You should be getting the whole flywheel from the wrecker and cutting the timing ring off yourself.

Any A33B-MT (02+), A34-MT and 3.5 L31-MT will have the flywheel you are looking for.

yevrah4728

ok, maybe this is another stupid question but, is the manual timing ring different from the manual? the 1 i got from fidanza is approx. 1/2" wider in diameter than the auto (A34) timing ring that came with the motor...

eng92

iTrader: (3)

I presume you mean "manual timing ring different from the automatic".

Yes they are different. The one for the auto has an offset to make up for the fact that the AT driveplate is much thinner than the MT flywheel.

You must mean "thickness" (or axial length) instead of "diameter". (for the reason cited above) The diameter cannot be any different because there is probably only about a 1/16" clearance to the face of the CPS.

aznsap

iTrader: (29)

anybody planning on doing a write up on how to do a full vq35 swap w/ a33b ecu anytime in the near future?

goldtooth

iTrader: (56)

There isn't much for a writeup as to the charts (spreadsheets) eng92 made. Then it's all up to the person to match everything up with the specfic car year in the FSM. Then you need the spacer for the timing ring, if using the 5spd tranny. Other than that, ?

nismology

iTrader: (8)

People looking for a write-up are looking for an easy button, IMO. A write-up won't make it any easier because what needs to be done depends on the year of the car; and in a few cases, its options. Either way you will have to dig through the FSM's to confirm where and how to make the connections.


Maybe there could be a beginner's guide to what needs to be purchased/acquired and an overview of some of the necessary connections... but the nitty-gritty of the wiring portion should be discussed with someone who knows what to do if one has NO idea where to begin.

yevrah4728

It is larger in diameter (the Fidanza) for some reason. When I measured them both I got approx. 11 3/8" for the auto timing ring and 11 7/8" for the Fidanza timing ring. But according to Fidanza, its for the 6 spd flywheel. I was thinking that maybe the cps differs in size with the tranny...So now i have to find someone who has a Fidanza fly in a 5.5 to see if they encountered any fitment issues with the aftermarket timing ring..

goldtooth

iTrader: (56)

Old engine is out, wiring is on the verge of being completed! Only obstacle I foresee as of right now is acquiring another 3.5 timing ring, or flywheel.

Unless, can I have like an adapter (or like another spacer/ ring) made to adapt the larger timing ring I have, to the spacer I had made? As long as everything is balanced out and within the specified dimensions, it should work fine?

I'm also going to give Nissan Only Wreckers a call tomorrow and see if they have anything for me. Hopefully, the 02 manual maxima they took apart for me for the harnesses, will still have the flywheel.

eng92

iTrader: (3)

I do not know what timing ring you measured at 11-3/8".

I have measured timing rings from an A32-5MT, A33B-4AT and an A33B/A34-6MT and they all measure in at a little over 11-7/8".

eng92

iTrader: (3)

If you look at the A32 flywheel (top picture) you will see that there is a raised portion of material with a radiused edge that the ring gear is welded to. If you make a spacer with a larger diameter than the one I did, it will need to have a full perimeter step machined into it on the flywheel side in order to clear this raised section.

goldtooth

iTrader: (56)

Aha!, I understand what you are saying, but since I already had the spacer made, I think there would be less work just making another ring to adapt the one I have to the spacer as long as the whole unit as a whole is .491" in height. (I only chose this route because my dad's friends do this while the boss is not looking, so the faster solution, the better.) LOL

hacim105

iTrader: (6)

Can I use the engine, 6spd transmission, and MAF from an 05 maxima?

NmexMAX

iTrader: (22)

If you have an 04+ ECU, yes. The 6MT is the same so whatever applies to the 5.5 gen 6SMT swap --> 4th gen, applies here.

As for the others, I don't believe anyone has done this yet. Most people stick with the 02 -03 ECU configuration.

hacim105

iTrader: (6)

I was planning on using the 02/03 ecu configuration. I just know that from reading other threads that you don't have to use an 02/03 engine, you can use an 04 or 05 engine and just plug the EGR ports. I just wasn't sure if the same applies to the transmission and MAF sensor.

But if the tranny is the same between the two gens, why I can't use the 05 engine/tranny with the 02/03 ecu configuration?

dfownz

iTrader: (5)

You can.

NmexMAX

iTrader: (22)

You can (plug EGR ports), but leave out the 05 MAF.

hacim105

iTrader: (6)

Ok cool. I think I might be able to get a fairly good deal on an engine and tranny from an 05 maxima.

goldtooth

iTrader: (56)

Here are the new timing rings I had made! This should work now?
