Thats it for the torque specs I have, if anybody has any i didnt list, let me know and ill add them to the list
I had to use an I instead of a 1 in the 10's or else this would show up (10)

The clearances will be updated in the next post, but it will take me a while to type them

Clearances

*Main Bearing Oil Clearance*
-Main Bearing #1,2,4,5= .0009"-.0020"
-Main Bearing #3= .0012"- .0022"

reserved2

Great info. I'll probably never need to use it myself, but it's good to have nonetheless. This needs to be stickied..

 

[95blkprobe]

thanks for the info! I Will def need these in the nest couple a months :thumbsup:

 

[twistiert]

awesome! this is going to help a lot with my engine build

 

[J_Naoto]

good info

 

[justanothermp5]

yea...i was going to update the 2nd and 3rd posts this week, but i forgot the papers at my parents place lol
ill update them as soon as i can, prob this weekend

 

[SoCalRyder7]

This should be stickied. Thank you justanothermp5

 

[Sport23]

subbin good info!

 

[TWISFM]

dont know how im not subbed... or do i.

 

[Outlawstar98]

ARP Head studs and ARP Main Bearing caps studs have different torque then stock just a FYI People, which if you take everything off I HIGHLY suggest putting ARP bolts on. Cant go wrong with them.

And there is a place with the build manual with pictures and everything. I know where it is at. lol

 

[justanothermp5]

i put the ARP main bearing torque spec up there already, i didnt have the paper for the ARP head studs, think i threw it away lol
i got some more specs printed off today, so this weekend after finals i should have a huge update to put up here

 

[dmention7]

So, does anyone have the main bearing clearance and piston-wall clearance specs? I have tried searching a couple times, but haven't found anything yet. I figure this would be a great place for that info

 

[justanothermp5]

s***, forgot about this thread lol

ill update the first post, but according to the resources i have:

02-03 Protege w/ 1991CC engine

Main Bearing Oil Clearance
Main Bearing #1,2,4,5= .0009"-.0020"
Main Bearing #3= .0012"- .0022"

 

[dmention7]

Thanks. Now I've read in multiple places that high performance and/or boosted engines are best clearanced at the upper end of (or even .0005" above) the factory range to allow for a thicker oil film. Any idea if that's true in the case of the FS?

 

[95blkprobe]

You build your motor according to what oil yiou will be using. Tighter clearances, thinner oil. I've heard that you build a higher revving motor to the loose side of specs. I followed this procedure as well

 

[dmention7]

Okay, I guess if I had actually read the entire spec sheet on my Wiseco pistons, I would have noted that the recommended piston wall clearance is .0025" at the lowest part of the piston skirt. I don't know what the OEM spec is, but hopefully that's of some use to someone

 

[Maxx Mazda]

Please add ARP head studs. Final torque 90 ft-lbs, in 3 steps. (30, 60, 90) following manufacturer's tightening sequence.

 

[justanothermp5]

Thats using the Moly Lube correct?

could have swore I had those on there already, ill add them in a few
