I Need Some Help With Turbo/water Lines On Rb25

[SargeRX8]

Hey all,

Well I bought a turbo setup kit which includes water feed/return lines and an oil feed line(I need to make up the oil return which is fine).

This is a link to the kit.

If you notice, the kit includes a oil feed restrictor but alot of people are saying that the Garrett turbos already have a build in restrictor... Anyone able to shed some light on this? Does this restrictor bolt straight to the oil feed port on the turbo? Do all the elbow joints bolt to the block? I'm trying to understand everything I need to do before I do it. I don't want those responses "take it to a mechanic, you don't know what you're doing". I do know what I'm doing but as its my first time I need advice. Id rather do this my self and save the money for a tune rather than pay someone to connect some hoses and bolts for me.

Also you will notice that one of the water lines has a barb on the end rather than a banjo bolt. Is this correct? I remember stripping my old motor but can't remember how it was setup.

If anyone can post a picture of an Rb25 block maybe labelled showing the oil feed, water feed, oil return and water return points on the block? I'm aware that the oil return goes towards the bottom of the block(I think) but have no idea where the rest go.

Back with the kit. You can see the two larger elbow joints. Ive gathered these will fit onto the block for the water lines. Then there is a smaller one... I have no idea where this goes. If it goes on the block, there are no other connections on the kit which fit into it. So far this is how Ive got it to work.

WATER FEED LINE:

BLOCK| BANJO BOLT BLOCK SIDE(OFF ELBOW??)| LINE TO TURBO | BANJO BOLT TURBO SIDE|

WATER RETURN LINE:

TURBO| BANJO BOLT TURBO SIDE| LINE TO BLOCK| BARB INTO HOSE TO BLOCK????(ELBOW???)

OIL FEED LINE:

BLOCK| BANJO BOLT| LINE TO TURBO | RESTRICTOR ON TURBO FEED PORT| HOSE TO RESTRICTOR

OIL RETURN:

Well I don't know yet as I'm trying to either find a kit or get a line made up.

Any help would be great, sorry if this causes confusion...

Cheers.

This is how it looks with everything on the turbo side. The water lines I think are fine but I'm not sure about the oil restrictor and oil feed line... Thats the only way I can get it to fit... The parts I have left are two large elbows, one large banjo, one small banjo and 1 smaller elbow.

garrett ball bearing turbo's have the restrictor built in u can see it from the top.

the barbed fitting on the water line end will be so u can connect up 2 a piece of water hose that runs around to the back of the head/firewall. rest should bolt up normally.

Damnit that means I need another piece now to connect the hose to the turbo. Could I use the restrictor or will it be too restricted?

Where can I buy a piece to fit in place of the restrictor?

my gt3082 didnt seem to have a restrictor, its genuine but i have the restrictor in the AN fitting i fitted on the turbo to connect the oil line,

can you post up a pic of the garrett restrictor as i am probably wrong and it is there lol

just to make sure
