Turbo install
Just finished routing oil supply and drain lines for my turbo. This is my first time and I'm wondering if anyone see anything wrong with the way I did it. Here are some pictures:
Thanks for taking a look.

Re: Turbo install
looks ok to me, but are u sure you used the right thread on the T in the block? seems like its not tightened properly.. its BSPT

Re: Turbo install
Looks good to me, but I probably would have tried to go around the engine rather than over it with the feedline - may want to use some clamps and standoffs to make sure it doesn't rub on anything.

Re: Turbo install
Make sure your feed line doesn't rub you spark plug wires, that would make for a nice miss fire eventually. Also, is that a ball bearing turbo??

Re: Turbo install
let me start by saying your set-up looks nice but here is my feedback...
oil feed line will work fine but IMO you should have routed it differently (from a looks standpoint).
as for the return what type of hose is that? is it rated for oil? if not it will disintegrate with a quickness leaving you with a nasty oil leak. even if the hose is rated for oil it will most likely develop a leak from the lower hose clamp. why not run stainless line and AN fittings? (or at leak push-lok stuff). peace of mind knowing you have parts that will basically last forever and never leak
lastly, you may be able to get a slightly better angle for your return line if you rotate the return flange/fitting out towards the front of the car just a bit

Re: Turbo install
Well this is my first and probably only turbo install I will ever do. I got a "turbo kit" that came with everything I "needed". For right now I'm taking my time with the install and learning as I go. I tossed the extra fuel injectors, controller, and MSD timing controller that came with the kit after doing some research and bought a P72 with hondata S300 and RC 660 injectors which opened up a big can of learning for me even more.
I have thought about ways I can upgrade other things to improve on the kit but for right now I'm just getting it setup and getting it put together so it runs nice. I most likely will always be upgrading pieces and parts.
I know exactly what u mean about the return line and I didnt even think about rotating the center of the turbo to kick that fitting out a bit, thanks for the tip.
Today I also revved the engine up from idle (900rpm) to 3000rpm with the turbo just sitting on the exhaust with no charge piping or exhaust pipe just to see how it spooled up, I took a video, I think its pretty cool! I do know that it will be different once the back pressure from the exhaust and the suction from the charge piping is hooked up but I still think its cool. Take a look:

Re: Turbo install
Uh ohh... I installed the downpipe today and started the car, still with no charge pipe, so no boost yet. When I revved the engine up a couple times I went over to look at the turbo and this is what I saw on the discharge of the compressor:
I'm guessing this is not a good thing? Oil blowing by the seals?

Re: Turbo install
your H23 motor will not like that log manifold anywhere after 4000 rpm.
Are you using an oil restrictor on that inlet line ? ..
With BB turbos its almost a must to use one, or you will have a result similar to what you posted above .. oil in exhaust housing, oil getting past the seal, black smoke out the exhaust.
Did you buy this turbo used ?

Re: Turbo install
I bought this T3/T4 turbonetics turbo brand new and I asked about using a pressure restrictor on the turbonetics forum and was told it was not necessary. The fitting on the turbo came installed on the turbo from the factory. I just thought of something... Could this be due to the fact that I installed the downpipe? Now the turbine section would be seeing some back pressure but the compressor side is free flowing. So I'm thinking maybe the pressure from the turbine side was pushing oil into the free flowing compressor side?

Since the oil drain is gravity fed, it is important that the oil outlet points downward, and that the drain tube does not become horizontal or go “uphill” at any point.

Re: Turbo install
I have heard that the oil supply pressure to my turbo should be 25psi...
I have a Honda prelude 2.3 Si and was wondering what the engine oil pressure was, I think its about 60psi, and how I could maintain a constant 25psi to the turbo or has the kit I have already accounted for that in its design?

Q: How is a turbocharger lubricated? Where does it come from?
A: A turbocharger is lubricated with regular engine oil. It comes from anywhere that you can provide clean filtered oil to it. Usually this is anywhere after the oil filter, before the oil gets to the block. Many turbochargers are oiled however from a fitting tapped into the block itself. As long as you have filtered, cool, and sufficiciently pressured oil your turbo will be happy. Note: Oil PSI should be at least around 20-30 PSI at idle and 50-70 psi under boost. Race applications do not apply here.
Your care most likely makes more than 70psi of pressure, especially when cold. The only real way to know is to test pressure at the oil feed inlet, then decide if you should add a restrictor. Bottom line, oil shouldnt leak past the seals and high oil pressure is the only reason I know of that would cause it

Re: Turbo install
I have the honda dealers maintenance manual and it states:
Engine Oil Temperature: 176'F
Engine Oil Pressure:
At ldle: 70 kPa (0.7 kg/cm2, 10.0 psi) minimum
At 3,000 rpm: 350 kPa (3.5 kg/cm2, 50.0 psi) minimum
I doubt the pressures are a lot higher than that. I don't think my engine oil pressure is out of the range from the turbonetics FAQ.
