Joeylyrech I am sure you already know all that... LOL This is really frustrating me. I wasn't trying to come off with an attitude. I am just trying to figure out what engine is in my car. I am getting alot of different posts here saying different things. Do all s5 engines have the extra hole above the trailing plug? Or just t2? Or just na?? Or all of the s5??

 

Take a picture of the block so at least i can tell you what plates and housings you have.

 

dont worry im just messing around,in fact i want To help solve this mistery FRANKEISTEIN ENGINE case.

 

Ok I looked by the spark plugs and above both of the trailing plugs there is an extra hole. On the rear rotor housing the hole has a goldish fitting in it I guess someone said the knock sensor?? I do have a pic of the front of the engine take a look. My camera sucks so this is the best shot I have for now.

 

All stock factory untouched S5 motors(turbos and na)have the hole for the knock sensor.
All factory untouched S4 motor(turbos and na)dont have the hole for the knock sensor because it goes on the center plate.
By looking at your engine picture it looks like a NA motor because you have the long tall oil filter pipe instead of a T2 one,you have a S5 T2 front cover,S5 turbo manifolds.now from were is your turbo getting oil feed.

 

if i can only look at the plates without the manis i can figure out if is S4 or s5

 

So. Do all turbo and non turbo series five front rotor housings have the threaded hole for a knock sensor?

 

sorry that wont work if we really want to get down to the bottom we need to know what compression rotors you have on the block,it might be S5 block with S4 NA internals or S5 block with FD internals,i guess that we willnever find out until you open the block or the person that sold you the car tells you what you have.

 

if you are standing by the driver side by the driver fender looking under the hood the oil feed line to the turbo is coming from the bottom of the front of the engine. Does that make sense?

 

they have the hole on the front and rear housings,well at least i have a blown S5 NA mazda reman sitting on the garage floor and it has the holes,also the S5 NA running in my brothers has the knock sensor hole two and that one is stock untouched,im calling my friend that has a S5 vert with stock NA motor to see if he has them or not.

 

no casting for the knock sensor on my friends S5 vert,so if you have the knock sensor there is a chance that you have S5 turbo housings or even FD

 

now im confused more info here http://www.rotaryresurrection.com/2n...g_differs.html

 

Ok according to rotaryresurrections info all s5 housings have the hole above the trailing plug. So my housings are s5 and so it my tranny. At least now I know I need to get a s5 clutch. Now the question would be t2 or 6 port. I guess if I take off my LIM I will be able to tell! How do can I take off the LIM any directions on here. I will search for it.

 

Joey looks like your friends engine is a s4 if he doesn't have the hole above the trailing plug on his housings...

 

take a picture of the tranny that way i can tell you if is T2 or NA,you cant take the bell housing of a NA tranny and on a T2 you can,that is one of the differences.

 

stock t2 location is off the top of the front plate right next to the CAS
NA conversions will have either a helicoil there
- or sometimes and adapter under the oil filter with a supply outlet
( and sometimes from rear of bottom oil cooler line banjo bolt, or from the oil pressure sender hole )

if it doesn't use the t2 location, its NA

if its using the T2 location, lift the banjo bolt to see if the star bung is drilled and helicoiled
( - the T2 is directly tapped )

ALL s5 engines have the knock sensor holes above the spark plugs, with a single brass knock sensor usually above the rear trailing plug

ALL s5 engines have a distinctive wedge added to the casting immediately below the oil filter pedestal
( a diagonal wedge that was found on earlier 12a's , but deleted in s4 )


- s4 engines have the knock sensor in the filler pipe base / primary plate
( hence housings have no added threaded hole )
and will not have the diagonal casting under the pedestal
s4 NA housings also have odd spark location to s4T, s5NA, s5T ( which are the same locations )



the rest of your car appears s5 - N370 ECU, N370 vortex AFM , N349/ 350/351 radiator
the front timing cover if mech OMP and oil drain is from an s4 T2
but the turbo can be either, though needs the correct s4 drain pipe
( cant see the turbo manifold to tell if its s4 or s5 )

 

I think I was trying to say, since he says both the front and rear rotor housing have a hole for the Knock sensor, then to me, he must have a rear rotor housing in both places.

That would hold water if Mazda only put the knock sensor hole in the rear housings on a series five.

Not that big a deal if that is the case. It only fouls the water if emissions have to be passed each year in his state..........and most likely he does not care about emissions stuff.

I don't own and never look at series five engines so I'm playing guessing games here. I have built and own a series four six port with turbo, so I know how to grind/fill/gut the series four turbo manifold to fit a six port. Just FYI.

And for the original poster: The afm is the cone shaped item with the filter. It's probably turbo like the boost sensor and ECU.

EDIT: And I'm pretty sure I can see the OMP rod just behind the OMP. Like on a series four. BUT if it's a series five ECU, and he has a series four OMP, then the ECU should be going into limp mode pretty often............unless he has the series five OMP hanging from the harness and tied back somewhere.

EDIT: Then again, that might be OMP oil line I see behind the pump. Never mind.

 

kk I know I have a s5 motor in the car. Now what I am going to do is pull the LIM to see if it is a na or t2 engine by the ports. While I am at it I am going to try to fix the leak.

I guess I am going to be dropping the exhaust, and down pipe to get to the turbo and LIM? Then inspect the LIM for cracks and check the gaskets. Now where do I get new gaskets to put back on if it is a custom LIM for the 6 port turbo?? If it is a turbo engine where do I get the gaskets too from mazda??

I am going to be heading out to sears today to buy some jack stands and tools. Any specific tolld I am going to need for working on this car. I am now going to be my own mechanic so when I say I am buying tools.... It isn't just for this one job. I like craftsman so I will be standing behind sears craftsman tools. They have a great return policy. I remember my brother in law found a broken socket in the street it had the craftsman logo on it. He brought ti to sears and no questions asked they took the broken socket and gave him a new one!! I couldn't believe it!!! LOL

 

Japan2LA sells them. Like the ones shown in the attached jpgs. Search on this forum using the word MANIFOLD and JAPAN2LA for some threads on it.

I made my own intake gasket.

Seems most of the JAPAN2LA threads out there have the jpgs missing. Below are some words he wrote on one of the threads:

************************************************** ************************************************** ************************************************** ************************************************** ****************
Guys, the reason my LIM looks different is because it is a JSpec LIM. It does not have any of that smog stuff. The manifold is all tig welded, port matched, and then faced off. I have tons of TII LIM's, but they are all Jspec...which will work. I have both S4 and S5 so you can tell me which you want..

You can also source you own TII LIM and send it in to be modified. I have done a few USDM LIM both S4 and S5, yet I do charge more as there is more weld work on those..and they are a bit more of a pain to work on.. Reason... I built a fixture to hold the LIm so that I can hold it on the mill while during face off. The USDM LIM's dont fit in my fixture due to the EGR.

Anyway $257.50 delivered for a modified Jspec TII LIM or S5 your choice.

Or send me your USDM S5 or S4 TII and I will modify and ship it back for $246.00
Or source your own JSpec lower and I will modify it for $206.00

 

Kk, I don't have the time to take the LIM off the car. I have two kids that demand a lot of my time and with work things are hard for me. I took mad pics with a new better camera. Please all help me distinguish if my engine is t2 or na. Remember I just bought this car so it needs work if you see anything that looks odd or like it needs work let me know. I would appreciate it.

Be patient might take a while to load a lot of pics.


I TOOK PICS DOWN WAY TOOO BIG BLEW WHOLE PAGE OUT> I WILL RESIZE THEN PUT BACK UP>>>>

 

Kk I tried to edit my last post to add the pics but it wouldnt let me so here are the resized oictures...

PIC OF ELECTRIC FAN AND RADIATOR



PIC OF CUT WIRE AND OIL SPOUT WITH SOME 13B WRITING ON ENGINE.

it has-
s5 turbo
s5 EOMP , fitted, must be operational to prevent limp with stock ECU
s4 ( square plug ) late high ohm injectors ( if oval plug are s5 )
s5 radiator
the oil supply to the oil coller is twinned-- does it run to two oil coolers?
does it split and run a seperate line into the turbo??= not the normal turbo source
or does it split and feed a seperate line to the front plate ?? = front stat oil mod

\

WHERE DOES THE TURBO GET ITS FRIKKING OIL FROM
?
WE KEEP ASKING!

need pics of top of centre plate ( looking for ACV passage = NA )
we need pics of underneath of oil filter = wedge = s5

we need pics of the CAS, front plate to see if its a bloody turbo engine with a normal oil supply


indiscriminate pics do not help, take the photos where indicated else you can continue to guess

 

Go look at that braided line I point to in each picture. Find out where that line Starts on the left side of the engine and where it goes to on the right side of the engine.

I think it's like the OZ man said, it begins at the fitting on the front cover that is tee'ing off to the oil cooler.

I'd bet the braided line ends up in the place/area shown in the third jpg.

 

I have owned 3 others but I have never done anything to my old ones but an oil change myself. I am a newb with the parts under hood and working or trying to fix it. Thanks for all the help

 

I'd go to the FAQ section of this forum, and download the series five FSM. And go thru the ENGINE and Fuel and Emissions Sections to get to know what is what.
