Hm... can't find them in workshop manual...
Though I found out that the intake manifold gaskets need to på relpaced, and also the exhaust manifold gaskets.

Another question: Should I go for the Xedos 9 intake tube between the intake manifold and the VAF, or get the one from the 626? Also, which one when getting the VAF?
ECU will I get from the MTX Xedos 9.

EDIT: Should I try to get the intake manifold from the Xedos 9 instead?

It makes sense to keep the intake configuration as close as you can to that for which the ECU has been designed. Using the Xedos 9 intake manifold, TB, connecting tube and VAF is a good idea.

I'm assuming this MTX Xedos 9 uses a VAF. If it's a MAF there will be a small wiring change required, the detail for which is on Probetalk. But you have to use whatever the ECU requires - you can't substitute a VAF for a MAF or vice-versa.

I don't know which Workshop Manual you are using, but if it's Mazda, the front & rear oil seal change is shown in Section B2, in the On-vehicle Maintenance subsection.

Hm... think it will be a bit expenisve to get the intake manifold also. Maybe I better try to get an ECU from the 626 from 92-94 then.

It's the 1995 workshop manual I've got.

The big problem now is the Mazdaspeed engine mounts. I have asked Corksport if they have them in stock, but haven't got any reply yet. Don't think they have them.

Oh, THAT ONE Thanks!

On what page in the manual can I find how to replace the Shifter Extension Rod Bushing? Can't find that one either.

J2-54, but it doesn't say much

[Macen]

Indeed...

What will be best, to get the ECU from 92-94 or try to get the whole intake and ECU from the Xedos? I mean, if I get a 92-94 ECU and VAF and then use the 95 IM, will that cause any problem? Or, as you said Ian, try to get the whole intake from the engine I get the ECU from, even if I get the 92-94 626 ECU?

Oh, another Q: The ECU is called ECM in the workshop manual, right?

I think there is no great difference between the 92-94 IM and the 95 IM, so 92-94 ECU and VAF and 95 IM should be OK. By the way, the VAF is the same for all years, so a 95 VAF is also OK.

However, just to make sure you can't use that 95 ECU, have a look at how many connectors enter it. If it's three, it's ok for your harness, but if it's four, you don't want it. In my manual the 95 model has 3 connectors, but the manual is for the US, and I believe the change in Europe may have been earlier, so it's worth checking.

Yes, the SAE changed from ECU (Engine Control Unit) to ECM (Engine Control Module) or PCM (Powertrain Control Module). See the table of abbreviations on pages G1-9 and -10.

[IanL]

I've just about changed my mind about the '95 ECU - see this thread

[Macen]

Hm, ok... But it still sounds much easier to get the 92-94 ECU
I will mail and ask the wreckyard how many connectors the '95 ECU have.

My manual is also the US one. It's the one that was online before. Someone sent it to me

The ECU have 3 connectors, so I will order the engine very soon. Just waiting for the Exedy clutch and my order from Corksport to arrive.

[Macen]

Any problems if I get the waterpump for the MX-3 1993-1997 or for the 626 V6 1992-1994? Mazda original to the 1995 is very expensive, and other stores don't have for the 626 newer than '94.

Any 93+ Mazda V6 water pump should work as long as it's not for the MPV minivan. But all the 93-97 cars with V6's should be K series engines, so those water pmups should all be interchangable. Different ones may have different connection for the pump's pulley to the pump rotor, but just make sure it'll work with the pulley you already have, and you'll be OK.

[Macen]

Great! Then I'll save some money getting the one for 93-94.

Hm... Mazda told me that the chassie number I have got from the engine has AC. Is there any problems removing the AC pulley? My MX-3 don't have AC, so I want to remove it. I'm going to change belts, and belt for alternator with AC is ~30mm longer than the one for only alternator (800mm).

[Macen]

Do I have to take the tranny out with the engine, or can I separate the engine from the tranny? Will be much easier if I could keep the tranny inside the engine bay.

I have removed all connectors and hoses now. Installed waterpump, timing belt, oil seal and underdrive crank pulley on the new engine. So now I want to lift out the old engine
