I cant seem to locate this How-To. If anyone knows where it is, let us know.

me either (rei)

what about all the vac lines it cant be the same as the 626 and dont the injectors go into the manifold as well

yes i said little details with the vacuum routing, it really isnt as hard as it looks, yes the rail is on the manifold but it only has two bolts holding it down.

there are only subtle differences in the vacuum lines and thats because you wont be using the vacuum controlled parts that actuate the butterfly valves

its the same motor between cars lol, the 626 uses the fs motor....thus it is a direct bolt on (other than a couple small vacuum differences)

but ya your right about the how-to, I forgot it wasn't hosted here it was hosted by nsnmotorsports...heres the link:
http://www.nsnmotorsports.com/docs/thermal.html

its a how to for the thermal spacer installation, but the process is exactally the same

as for the vacuum lines, its not a big deal where you place them on the manifold, just make sure that all of the lines before they reach the manifold go through the solenoids and other parts the same way they did before, its really not that different between the two

Thx for the How-to. Im still not sure what parts i need to get from the 626. Is it just the Mani? or do i need
- manifold
- egr pipe
- throttle body gasket
- intake manifold gasket
etc.

you will need all the parts you just mentioned... or instead of using the 626 egr pipe you could use the corrugated home depot gas line... also your gonna wanna get all new o-rings and such for the injectors

 

[special--k]

sounds complicated, how do i know what o-rings and s***?

 

[neox.286]

its not, an o-ring is an o-ring...just gotta go down to autozone and pick up a generic o-ring set and use the best (tightest) fitting o-ring wherever there was an o-ring on there before....it is definately a good idea to replace them

youll need:
manifold
egr tube from a 626 (highly recommend this cause its got the proper compression fittings on each side, but you can also use home depot corrugated gas line like 808mp5 said...I used it for a while myself)
throttle body gasket
manifold gasket
and I highly recommend replacing the egr gasket, as well as cleaning out the egr when you swap....just a good thing to do so you dont have idling issues later on (which happens a lot on the protege)

good luck (thumb)

The o-rings are brittle plastic. If they don't break when you pop them out of the old manifold, I would think that they're reusable. I could be wrong. Either way, I've done two manifold swaps and reused the o-rings both times.

Think this is something an average person, with normal tools can do? for the egr tube, and gaskets, sell these at auto value? prolly?

not sure exactly what i was suppose to learn from that thread... its really not specific about the details.

 

[808MP5]

damn i can't seem to find the GB on the EMPIRE's Perrin Fuel Rail Thread...

i posted all the associated part#'s for the fuel rail/fuel injector parts there.. i think it got trashed

Sorry for my lack of knowlage but, is a EMPIRE Perrin Fuel Rail the same as a Manifold. how does that work.
Im a little hesitant to try this project because i have NO clue what im suspost to be buying. I might take a drive to the junk yard this week and see what they got.

No offense, but if you don't know the difference between a fuel rail and a manifold, I wouldn't attempt to swap manifolds on your own. Maybe if you have a buddy that's mildly familiar with automotive work in general, you could have him help you out.

thats a Given lol i have a friend that works at Mazda. Hes going to do most of the work. Im just trying to improve my knowlage by talking with you nice people.

Great! I would ask him to explain everything he's doing as he does it so you can pick up on some procedures and terms. That is, if he's a patient guy. Hehe.

re-used all my old hardware, vacuum lines, and o-rings. only issue i had was a vacuum leak between the manifold and the head when i first started it.... make sure to go over those bolts twice!

 

[neox.286]

be careful with the head bolts though as they do tend to strip if you over-tighten them....they are quite weak

Ive reused the o-rings too myself, but over time (and after upgrading and downgrading injectors a few times) they all did break and I have replaced all of them

just depends on your luck
