Need help getting my lines right

I have the GT35r kit for my car. But I have to build the oil and water feed lines. Any one know 100% what size lines I need for each and what size the fittings going into the turbo are? I know the line sizes matter as Perrin's old kit use to cause smoking issues due to improper (too much I think) oil flow.

 

paging matt/drew.....

 

I know exactly what size lines you need. Are you running wrx heads

 

Yes WRX heads.

 

The much flow is because the Garrett BB Turbo's require very little oil since the oil is only being used for lubrication and not to cool the turbo. You can buy a reducer made for the BB turbos from ATP.

They also make one for a -4 line.

 

you need to buy the reducer for your turbo. -3 or -4 line will be fine

water lines need to be -6 or -8

 

So if I get -4 line I need to get the reducer also? Or use just the line? The simpler the better. Oh and what length would I need for each?

Any ideas the sizes of the fittings that go onto the turbo itself?

Thanks.

 

You still need the reducer. You only need a pinhole size oil feed for the turbo.

You can buy the fitting that goes on the turbo from ATP as well. Or you can call the anti christ Matt and I am sure he can sell you everything you need for less than anyone else. You two might actually have to agree on something though.

 

Do what? I just bought something from Matt and met him Wednesday to pick it up FYI.:unamused:

We are cool now

 

you have to install the turbo then measure for the lines, that turbo sits in a different location than most

 

Cool. Thanks Matt.

 

don't they use a tiny orifice plate in the oil feed line?

 

That's what that reducer is that Integroid posted.

 

eh they're a little different, but same basic concept.

 

garret recommends you use the fitting in the turbo

 

Care to explain? Fitting in the turbo? Pics?

 

The reducer from ATP goes into the turbo ....the oil line connects to reducer fitting. Taaa daaaaa.

 

Thanks! I wasn't sure if it was that or something in between two pieces.

 

what fittings are needed for the oil supply off the block? I think if memory serves me right that the coolant is coming off the reservoir up top so it's good to go.

This fit fine on my rotated setup.

 

I no have AVCS

 

DOH! It is a metric banjo fitting but don't remember off the top of my head which metric bnjo fitting it is. PM Matt and he should know.

 

I think it's 14mm. I swear Nasioc search sucks!

 

I was thinking it is actually a 10MM banjo bolt but you use a 14MM socket to get it off.

 

Hmmm I guess I'll have to use the spare heads and dig through my bolt assortment and see what fits.

 

Its either 10 or 12 I don't have a wrx line here right now or I would check.

 

Its a 12mm banjo.

Now next question. If I use a -3AN SS feed line do I even need a restrictor at all?

 

Yes you have to use a restrictor l

 

Okay cool.

So 24" Braided line with male open end -4AN on one end and 12mm banjo on the other. Get the -4AN to -3AN restrictor. Restrictor goes to turbo, male end of line into top of restritor and banjo to head.

Now for coolant lines what do you guys do? Use a barbed fitting and clamp? Also what size is the oil return line?

 

No, you just need the GT series -4AN restrictor. This does not taper down to a -3AN. They also have a -3AN restrictor for people using -3an lines.

 

Ah gotcha.

Now just got to figure out the coolant and oil return dealio. Are you barbing into the stock lines?
