I finally got a exhaust manifold and turbo outlet. I did some research and narrowed my decision to a Tomei Extreme manifold and Circuit Sports outlet but decided to scrap those plans and get those items when I upgrade to a new T28 and go front mount. For the stock turbo I just went with the best "bang for the buck" setup.
Tools needed:Socket wrenchSocket extension13mm socket14mm socket15mm socketNeedlenose pliersScrewdriverHammer(you'll see why later)Anti-seizeThreadlockerRazorblade
I got a setup in the other day.Megan Racing turbo manifold.Megan Racing turbo outlet.OEM T25 S13 TurboOEM multilayer metal exhaust manifold gasket part#:14036-75F00.OEM metal turbo inlet gasket part#:14415-17M00.OEM metal turbo outlet gasket part#:14445-26E00.OEM turbo locking plates part#:14495-40P10.OEM exhaust manifold washer part#:14037-42L02.OEM exhaust manifold nut part#:08912-8401AThe manifold came with new studs and hardware, like a brace of some sort. I went ahead and installed the brace...and seated the studs into place. Don't forget to use some anti-seize on the studs all around for the future if need be.Take the turbo inlet gasket...and place it on.I had to back it off a bit so that I would have room to put the locking tabs and nuts on.Like so.The manifold came with some nuts but they have flared ends so they pretty much covered the tabs on the locking plates so I used a set of M8-1,25 from the parts store instead. These are just like the stock nuts that I originally removed from the turbo and they don't have flared ends so you can fold the tabs over these nuts...can I say that?!While I was at it I decided to use some threadlocker as well because I had been reading a lot of threads about how these have a tendency to back off because of all the pressure from the turbo.Examples......I put the nuts on next. Space is tight so some of them are pretty tricky to get on unless you've got those little monkey hands.To get one of the nuts near the top of the turbo inlet on, I had to remove the water line for extra space.
Next, I tightened and torqued to 16-22ft.lbs.Use a set of needlenose pliers to fold the locking tabs over the nuts.Like so.
The nut on the inlet side was hard to get to with the pliers so I just used a screwdriver and a hammer to bend the tab on this one. This is where the hammer comes into play. The manifold is mounted to the turbo so now you can install it on the block.Exhaust ports.I had some old gasket still on the ports so I used a razorblade to remove it and clean the area before I placed my manifold gasket on.Take the exhaust manifold gasket...and place it on.Take the turbo and mount it on the block.Break out your cleanin' gloves and lube up the studs with some anti-seize before you put the hardware on. This stuff STINKS!!!!Place your exhaust washers and nuts on.From here you need to break out the FSM(factory service manual) because the nuts need to be tightened in a specific order.Tighten and torque to 27-35ft.lbs...and the manifold/turbo is mounted.Now on to the turbo lines.I started with the water line.On a S13 SR it will connect here. On a S14/S15 SR, it connects to the water neck unless you get a S14/S15 water neck and use it on a S13 engine...you confused yet?Use a screwdriver to loosen the fitting...and place it on the hardline here. Tighten it back with the screwdriver.Water line.I moved to the next water line.Take the banjo fitting off, the two crush washers that should be supplied and the stock banjo bolt. Like my new gloves, hobo style FTMFW!Put two crushers on both sides of the banjo bolt and install.Tighten and torque to 14-23ft.lbs.Lastly, the oil outlet line.Remove the fitting and the crush washer.Place it on the block...tighten and torque to 14-23ft.lbs.Almost complete!I can't install the turbo outlet yet because the people I ordered it from forgot to pack in the hardware(studs) so I'll have to wait on that.
I also don't have a O2 sensor or adapter yet.
TO BE CONTINUED...
