Hey guys I am nearing completion of my project. I had to replace my block so I am in the final stages of putting everything back together and I have some questions so I can make sure I am doing everything right.


1: Oil inlet. I have a journal bearing precision turbo and I am trying to figure out which flange to put on and if it should be restricted or not.

2: Air pump. I just upgraded from the Emanage to the EMS and I know that I can now take out my air pump. Do I just remove the pump and thats it or what all do I need to take off. Also do I need a block off plate for the intake manifold?

3: I built the head minus new springs. Do I need to break these in before I start boosting a lot and when I'm first starting my car up from something like this is there a certain procedure that I need to follow like priming the car with oil or something.


Also if there are any other things you guys have experienced and recommend that I do and look for all suggestions are welcome.

 

I am still doing a lot of reading/research on here, but I think i can help a bit. You can remove the entire air pump assembly and yes you will need a block off plate.

Where to get the plate-

Inlinepro makes a block off plate for your intake manifold a little over $20.00.

Or make one

 

Thanks guys took care of the block off plate. Any suggestions on the other questions?

 

use the search button. it is your friend

 

Ok so I did some more searching and I answered the first 2 questions but I couldnt find anything on my last one as far as what I should do when I;m first starting the car back up if there are any special things I should do.

 

Pull the fuel pump fuse (15a under the dash) and crank it over several times to get the oil pressure up. As for the lubricating the cams, it can't hurt anything. Just use some of the engine oil you plan to use and put it on the lobes.

If you have already primed the fuel system you may want to pull the coil packs too since it will fire off any fuel pressurized in the system

And there isn't really any break in on valves just make sure your valve clearances are in check. Break in is more specific to seating the piston rings but that's a whole controversy of it's own.

 

I highly recommend using a restrictor for journal bearing turbos with this motor. My JB turbo seals went out the first day so I added a restrictor, replaced the turbo and never had an issue again. Precision will tell you to NOT run a restrictor but this does not apply to the S2000's. Some have had luck without using a restrictor but I wouldnt risk it.

As for the air pump, you can leave it or remove all of it, but be sure to use a block off plate if you remove the intake manifold valve.

As with any new build/turbo, be sure to prime the motor before starting it. Good luck!

 

Ok so this is the inlet flange that I got and the hole in the bottom. Is this an ok sized hole or should I drill it out? All my pictures are coming out black for some reason so if you click it a few times it you can see it.

 

did anyone ever figure out a headgasket to use? i have the .50 over bore also...
