for those of you who are scared to take off your intake manifold because it looks hard, well here is how to do it. use this as a checklist to make sure everything is reconnected. i will also tell how to put in a rear mount, phenos, race kit, rear VCG, and t.b. coolant bypass.
tools needed: 8mm socket, 10mm, 12mm, 13mm, 17mm, swivel, long extension, adjustable wrench (or a set of metric), jackstands (optional), jack, peice of wood.
parts recomended: mazdaspeed rear mount, rear VCG, phenos, race kit, sealant for IM, 2 bottles of powersteering fluid.
to remove intake manifold:
-let engine cool
-(optional), jack front of car up and put on jackstands
-releive fuel pressure by removing relay under hood labeled "circuit relay". it's green. then try to start car.
-remove:
1. front air scoop 10mm
2. VAF harness
3. big vaccum hose on rear of intake elbow. disconnect from elbow
4. FPR harness
5. FPR vaccum hose
6. vaccum hose from rear of airbox
7. PCV hose
8. vaccum hose to #6 runner
9. airbox bolts 12mm
10. airbox and filter
11. intake elbow and VAF
12. throttle cable. (open throttle fully then pull end of cable from the rocker thing, then remove the whole assembly from the IM by pinching the clips together and pulling it through.)
13. hose from front V.C. to IM (forgot name)
14. banjo bolt and washers 17mm. (don't lose the washers)
15. the 2 fuel rail harnesses
16. knock sensor harness (long and gray next to t.b.)
17. tps harness
18. VRIS solenoid harness 1
19. VRIS solenoid harness 2
20. harness next to them (forgot name)
21. fuel line to FPR
22. 2 rear bracket bolts. warning: these are a bitch. they are 12mm just so you know. you can't see them. they connect the back of the IM to the back of the rear head. it works best to crawl on top of the engine and reach back there. one is on top and one is on bottom. they both point towards the front of the car.
23. 2 harnesses from the bracket
24. IAC harness on bottom of throttle body.
25. 3 coolant lines on bottom of t.b.
26. big vaccum hose under passenger side rear of IM
27. little vaccum hose un passenger side rear of IM
28. rear spark plug wires.
29. front spark plug wire bracket screws. only the screws need to be taken out. the brackets themselves can stay clipped onto the wires.
30. big vaccum hose from IM to brake cylinder
31. manifold bolts and nuts
32. manifold. (lift front first then pull up and out. it will not come all the way out because there are still 2 vaccum hoses holding it in. they are connected to the bracket. disconnect them so that the bracket will come out with the IM. the bracket should be dangling from the IM. cover the open holes in the heads with a rag or something.)
now, to do the rear engine mount:
1. jack up engine by oil pan to releive stress on rear mount. note: place the peice of wood between the jack and oil pan. do not jack near drain plug.
2. use a 17mm and remove the bolt that goes through the bushing. remove nut also. if the power steering line is in the way of the bolt, losen the line and set it aside. it's strong, use force to move it.
3. remove the 3 bolts on top of the mount. use a swivel if necessary to get to the bolts. they will be very tight.
4. the mount should just come out. look how crappy is is compared to the mazdaspeed one.
5. put the new mount back in and tighten everything. put the bolts halfway in, then put the bushing bolt through. then tighten the 3 top bolts.
6. put the powersteering line back on if it was removed.
7. after the IM is back on, add powersteering fluid.
to put in a rear valve cover gasket:
1. if you are still motivated to put it in then remove the 11 or 12 10mm bolts holding the VC on. take cover off. oil might drip from cover.
2. take out the old gasket and put the new one in.
3. put RTV sealant on all 90 degree angles around the mating surface.
4. put the cover back on.
5. if you have the zinc plated bolts from
probesport.com then use them. but if not, put the old ones back on.
6. tighten them to 72 inch pounds or until you think they are tight.
to install the race kit and phenos
1. the race kit comes with longer stufs to go into the heads. use pliers to twist out the 4 old studs from the heads.
2. this will make metal shavings. do not get them into the head ports.
3. once all four are out, install the new larger ones. i used a pipe wrench to get the new ones in. be careful not to strip the threads.
4. when installing phenos, put sealant around both sides of each port hole. the stock IM gaskets will not be used.
5. use a vaccum to clean up all metal shavings from around the heads.
6. when the intake manifold is back on, put the hardware from the race kit on in this order: insulator, insulator, washer, bolt. same thing with the studs.
