subaru ihi rhb5, bad turbo???? help
 

Okay, I just put in my turbo kit in this weekend, but for some reason the turbo keeps spittin out oil from the exhaust side? Does this mean that the turbo is bad, or is it common on these subaru turbos? Also I have it in my sohc d15b. I have already went thru 3 of these turbos and still the same. I got it flipped the right way, (feed on top, drain on bottom) still not working. The car will boost just fine but it will smoke like crazy because oil keeps coming out. Oh yeah, turbo came out a 88 subaru. HELP ME!!!!!!!!!! THIS IS BECOMING A HEADACHE AND A PAIN IN THE ASS. LET ME KNOW YOUR SUGGESTIONS.

so is blowjobs, but i dont see those for sale around here

.060 to .125 (1/8") is generally whats used for restrictor sizes. or get a stealthmode restictor

thanks guys, i'll give it a try and l'll let you guys know how it goes. Anyways i heard that the ihi rhb5 subaru turbo is a "ball bearing turbo," is that true? Lmk

what model is the turbo? VF__

btw, its probably not a good idea to throw on an adjustable restrictor, and just choke off the turbo. get an oil pressure gauge and make sure you see what pressure your adjusting the line to. you should be able to find a recommended number for that turbo through the dealer

Just a guess, VF11

well guys, the oil restrictor (.063 orfice) is on it's way. For the time being I changed my oil feed line. The old one was a 4an and i just put in a 3an. It made a bit of a difference but in heavy acceleration oil still spits out. Do you guys still think that there is to much pressure? Lmk, also if anyone has the same setup, I would like to know if you had any of these problems. Thanks guys, more info would still help. I will keep everyone updated.

Any updates with your oil problem. I also have a IHI RHb5 Subaru Turbo and it :6 like a mother.

Re: subaru ihi rhb5, bad turbo???? help
 

u have oil drain problems, its either clogged or restricted

^^^Or your CHRA is mounted too low. They don't require a ---- ton of pressure or flow. Only about 700cc per minute is needed.
