a couple quick pics of my single

good info dre. i wonder what i have on my car. is there anywhere -3 or -4 is written on the line or the fittings?

Conrad knew this cuz he confirmed this when I asked him., he proly did some small hack to your nipple to restrict the flow .
He's old school when It comes to turbos and the man know his combos.

btw, does anyone know who is needing a Boost Controller, I got an eo-1 I need to sell.

From what I've experienced on my 1JZ, the oil pump operates at pressures up to 75psi. I've been toying with the idea of putting a restrictor on my turbo. I may just go and do it now.

i'd love to have an E-01 again but im broke for a while

the blackplate looks weird.. not like any garret i've seen, either way its a good turbo... no play and daneyan used it fine..

fwiw i ran -4 on my car for over a year no problem.. But yea too much oil can be bad.. Turbos only need like 20 psi of oil pressure to operate.. the 1js im sure make 60-70 psi @ redline.. -3 is a bit more restrictive so say only 50 psi is getting to the turbo instead of 70 psi.. On an older turbo the seal may leak.

Ow tissimo! you were probably dreaming away looking at this big boobed blonde in physics class... :boobs:
You should know that pressure spreads evenly in fluids in a fixed volume, so if the pump is putting out 70psi, thats what the turbo will get also.
The restriction on the turbo feedline is volume, not pressure.

but its not a fixed volume.. it bleeds out. cut flow and you cut pressure.

but its not a fixed volume.. it bleeds out. cut flow and you cut pressure.

The volume of the part of your engine which has oilpressure is fixed. The volume of all canals, bearings, lines and whatever added up is fixed, so if 70psi is generated at the pump, 70psi is what goes into the turbo.
After the turbo it falls into the oilpan which is not a fixed volume of fluid as the crankcase contains air. So yes, right after the turbo there will be no more pressure on the oil.
You are correct in saying it bleeds out, if that didn't happen at various parts, then there wouldn't be any flow, but as there's more being pumped in then being bled out, pressure is being build and that pressure spreads out evenly in a fluid.

But your thinking to reduce the amount of oil on the turbo to save the bearing was right. However the thing you will be reducing is the amount of pressurised oil, not the pressure.
