Is that a turbo with both coolant / water and oil lines???
If it is, you can't just plug up the holes!!!

i don't know........ but that picture is not my turbo,it's just where my hole a big one...if it is where i get the coolant line from?the radiator,where..please if any can help.....thanks

dis a picture of my turbo....................same one but mine is on my motor......................

If the lines are not needed, then plug a hose into it and into the hose a nail or something.

Sometimes with generic models extra things are put on it to suite a variety of parts.

If this is the case, then just block off the holes with anything u can find.

are you sure cause if it is some special line i'd might need it or it may cost me.....which i can't deal with....does anybody out there own a turbo like mine HKS GT-2530(jdm

how about you post a picture so we know what you are talking about!

it is that big bolt on the first picture,the other picture is just a similar turbo of what i have .......i 'd tried to take the picture but i can't for all you silvia owners ya know what i mean it's hard to get in thseo area with all the piping and everything in the way plus i got alot of aftermarket crap all around that area all up on walls and stuff........

if it is in the center of the impeller housing (which is seems to be) it's more than likely an oil feed line. check to make sure the OTHER lines are water/oil vice versa. you'll know which one it is by then. 90% chance that you wont have to use it but if you plug it up, be sure to use the proper brass fittings and not a generic plug; you dont want an oil leak on a blistering hot turbo causing a horriffic fire and burning your car down. have a nice day!

where exactly is the hole?
I have seen lots of JDM turbos that had a hole drilled into the turbine housing for the EGT sensor.

Make sure you have both of your coolant/oil lines connected before you block this random hole off. One send and one return. You need both lines. You may have forgot to connect one, don't block off this hole.

i'll check and tomorrow i'll let you know ...thanks for letting me know...

water and oil lines...

obviously your standard turbo is only oil cooled so the water line thread will need to be filled - youll get away without running water lines to the 2530... just make sure you put your oil lines to the oil threads (send and return lines) and not the water one - use a 12mm bolt to fill the water line thread (im pretty sure its a 12mm... could be a 10mm)

and vwalla - enjoy your new 2530, good spool time, efficency range begins around .8 bar till 1.3bar...

how hard was that to post? some of you kids need cars!

if you can please send me a pic or something cause i not that good with turbo setup ...this is my first turbo so please bare with me guys ...i wanna know more......thanks

thanks now i know ...it's the turbo coolant feed line right so i'd would need it..right.....i'm most positive it is right ....and i am missing that feed line....please someone tell me...help

You guys are crazy to just "plug" coolant lines and expect the turbo to be reliable.

OK....

assuming you have s13

There are 2 lines from the front center of the block that go to the turbo these are the oil and water feed's. I believe the smaller line (the one with the 17mm bolt head is oil) the other is water. The oil return is just a rubber hose that goes to bottom rear of the block from the bottom of the turbo. if you have those 2 connected you have oil running through the turbo. there is also a metal line that should bolt onto the back center of the turbo that comes from the back of the motor this is your coolant return. So if you have all 3 of those connected the only thing you are missing is the coolant feed in which you can just buy a custom water line from K's Factory or get a whole new kit from here. http://www.store.yahoo.com/phase2mot...srt25tuli.html

I also reccomend you get this http://www.atpturbo.com/Merchant2/me...gory_Code=GTBB
right at the oil feed on the turbo. and restrict oil so you do not blow the seals.


Back in the day with older non ball bearing turbos (sleeve bearing) you could get away fine with running just oil. But with Ball bearing and dual ball bearing turbos they do not run near as much oil through them so the oil does not cool them well at all. they were designed to use water for coolant. Will blocking the water line work yes.......will the turbo last ? Most likely not......

Hope this helps
