Big16g Oil supply line location

[badboyr66]

So, if it is better to run it from the housing....pressure wise....what and where do I need to get the stuff to do so?

I tried running a -3 line from the oil filter housing to a big 16g. It is way too much pressure and was forcing a ton of oil past the seal on the compressor side and the piston ring on the turbine side, switched it to running it off the head with ss line tonight so hopefully it should be good.

My ss line has a very small hole in the inlet bolt so oil allowed into the turbo bearing housing is restricted. Of course the oil return is large. 2nd gen motors hav their turbo's supplied from the oil filter housing? Mark

Yes the turbo oil supply line comes from the oil filter housing and throught a high pressure line. My tdo5 b16g has the same oil soure as you can see in the picture on the first page, my line is from rre and may or may not have the restrictor in it. The turbo had 6k miles on it with the same type of source and now has about 18k miles total on it all those miles are with the oil supply from the oil filter housing and its running great ::knocks on wood::.

The hole in the top of my EVO has a small hole while the outlet is large. One member who had work done by buschur has had his on for some time with no problems. I will watch mine and compare the inlet hole on the 14B to the EVO 16G. Mrk

update, installed feeding from head and it runs fine i guess. it runs as it should, didnt really boost over 14psi because im still breaking it in but hopefully it will run smooth. i contacted slowboy about the line, and they said feeding from the head is fine for a big16g and that the SS line they provide for a 1g is supposed to feed from the head anyway. im sure i wont have any problems with this one.

did swap today went to the stocker location . Just a side note trying to thread that bolt is a MO@#$%@R$@$%@%@#% @#%#@%@#%@#$ er so just take your time

I was always told from shops and such that with a Mitsu style water/oil cooled stock-style center cartridge that the stock oil feed location from the head were just dandy. With dry bearing (oil cooled) like the garett turbos is where you want to get the more constant pressure from the oil filter housing to float the bearing, unless its a BB GT style too much oil pressure can shorten the life.

i know with my turbo B16 and a t3/t4E turbo we pullied from the back of the honda head and then restricted the flow down to 1/16 other wise the motor pushes to much oil to the turbo.

i just recently put the 18g on my car with some other sruff and am running the oil from the head. i have been reading that the oil filter housing is another option than the head. i have the oil feed from the head.

my question is, this a good place or should i switch to the oil filter housing?

www.roadraceengineering.com has a good explaination with pics under their tip section. www.agpturbo.com has an awesome oil feed line for $50. I have not tried the RRE line. Mark

Yes it does offer higher pressure and that is what will get you in trouble. The stock mitsu turbos were designed to run between 5-20 psi of oil pressure. You can get as high as 100psi or more of pressure from the oil filter housing. Can you imagine how much force that is on the turbo oil seals? 9 times out of 10, oil willl be forced past the seals and then you will start to have problems. I would suggest retricting the oil flow to the turbo if you are feeding it from the oil pump. I wouldnt want to see you waste a new evoIII turbo and Im sure you wouldnt either.
