Sounds like it is coming from the front of the engine. I can't make sense of what is going on. If anyone has any ideas please let me know.

Yeah I was almost thinking ps pump myself. Other than that I was almost thinking it could be the tensioner pulleys on the timing area.
the car also has a misfire issue when it gets higher into the rpm but that could be a coil issue. Wish I went usdm now just so I could read the codes

The misfire only comes when the car boosts above 15psi. It is a sudden jerk of power loss and I push the clutch in because it scares me. I have stopped allowing the car into these boost lvls since then.

You can still read the codes on these cars by connecting the black plugs together under the dash.

How to read CEL codes

If you dont know the condition of the timing componets I would replace them, 3 days into getting my 20K on the road I had a idler pulley seize at high rpm and bent every valve. It was so much fun replacing all the valves and finding the shim buckets to adjust everything. As for the 15 psi that seems to be the limit until you can supply the fuel it need. What kind of fuel pump are you using? What ECU are you using as well?

we did the timing belt and checked the pulleys and tensioners when the engine was out of the car. They didn't show any signs that they were bad. Spun freely with no noise.

Using 340Lph fuel pump and using the JDM ecu that came with the engine.

I need to get under the hood and check out that power steering.

so I look under the car and found some fresh oil on the cross member and header. Looks like my head gaskets went. I ran my hand along the edge of the heads and found oil at the bottom. Think this might be the issue.

well pulled the codes.. 33 is vehicle speed sensor which I need to change out. Could the ecu be getting the wrong speed/rpm and it could be as simple as that? Second note the oil is the valve cover gasket which is not as bad as the head gasket.

Installed a new vss and just filled the power steering fluid reservoir some more. No misfire on boost and no more whining noise.

Now to figure out why my gauges are reading like this. This is at idle http://i.imgur.com/ANTqWgi.jpg

check your grounds, and the JDM harness has a different pin out then the usdm cluster so check all your inputs and outputs.

here is a video of what they do when you first install them. They start off at 0 then when you give them power they creep up for some reason I don't know.

My 96 sti made crazy power steering noises, changed the fluid and it's good as new. Used synthetic redline automatic transmission fluid.

Yep I added new fluid and it is as good as new.
I need to figure out my gauge issue. It sucks not knowing the proper rpm and speed.

check your alternator voltage; overcharge will make your electronics do very funny (and unpredictable) things.

if you see in the video this is when I just turn the key to the on position. Just incase I did check my alt voltage and it was 14.1-14.4

do the needles ever move? or do they stay still regardless of speed/rpm?

yes the needles will move. Its almost like they are moving to their start position (0) then once the car is running it will move just like any other needle but is off because of where they start. If you compare the picture to the video.

The picture is when the car is at idle.

If you grounded the cluster properly, then maybe you tapped into the wrong wires for the tach and vss.

they function but doesn't explain why they move to that starting point when you turn the key to the on position

Update - this is the car at idle now. Still not sure if it is reporting correctly. 3k rpms does not sound like 3k rpms to me. Either ej20ks rev high and fast or my gauges are still off.

have you tried reattaching the original cluster to see if it's reporting the correct value?

no can do this is a 98 rs and has totally different connectors. I found a local guy we are gonna swap his 99-01 cluster in there to see how it reacts to make sure it is reporting properly. I will report back with our findings

found out the needles were messed up. I since hooked up the ecu to my computer through enduring solutions and moved the needles manually to the zero points when power was applied. I then moved them when the car was running to the proper locations and verified the rpms in the ESL program. Car is 100% and added 4lbs of boost along with larger injectors of course
