-5 Oil Feeds

[trustr32]

Hey guys just Want to sort this out before my engine goes in I read somewhere on here a while ago that when putting ball bearing turbos on a car ie 32GTR that you may need oil restrictors in the feed lines. I've done a heap of searches and can't manage to find it again so Im wonderin does this apply with my application or do Garrett restrict all their direct replacement turbos such as -5's?

Cheers in advance.

I used the standard banjo bolts. The 5's have restrictors in the core from the factory

There's gotta be a reason why HKS supply banjo bolts with restrctors built in with their GTRS & GTSS turbo kits so one can only assume they are needed.

if you need the banjo bolts with the .8mm restrictor in them, you can get them on ebay from kando_dynamics.

Those turbos don't have restrictors in the core.

Those turbos don't have restrictors in the core.

What so the HKS units aren't restricted but the garrett ones are? Anyone else know for sure?

[Piggaz]

Well the HKS GT-RS's that came off my car had NO restrictors in the core BUT had really stupidly small oil holes in the banjo bolt.

The off the shelf Garrett -5's that replaced them had the restrictors in the core hence no need for the HKS banjo's. Stock banjo's went back in.

Double post. Shit phone!

Look into the oil feed and see if it is restricted.

My -1/-9 I installed last wk had the restrictor built in the core....To the bottom of the hole was completely sealed off, and to the side about where the thread stops there was a tiny hole probably 1mm or less. You actually have to look good to see it, and honestly I think the -5 would be the same.

Always wondered why HKS lncluded the banjos in the gtss kit....Probably just to justify the price : )

You'll also have a little work to do with the front turb oil drain pipe to get it to work.

BTW....No need to worry about the whole "S" thing....Just labelling AFAIK

Half the problem is knowing what to look for.. when you look into the oil feed on the turbo you don't easily see the 'restrictor' part. But actually you are looking right at it.

I took a photo of mine out of the turbo. You see the tiny hole on the side (this one is 0.8mm, the -5's came with 1.2mm originally)

hope these photos might help.. but to summarize, yes, -5 do come with a 1.2mm restrictor.

(oh and yes this turbo pictured is a -7.. but -5 is same)

Youre so coool....I didnt even know that could come out haha

[blue_vl_t]

So do you run a higher pressure aftermarket oil pump?

Is this the reason for changing the restrictor size. First I've heard of someone doing so with bolt on garrets

Yeah Cheers man I've gotten to the point where everything measures up the same looks the same and to all accounts IS the same apart from the tags so they're going on lol!

Cheers R32 TT pic's will help out alot. I thought they would be restricted from factory just wanted to be sure.

Blue_vl_t yeah I'm running a trust aftermarket pump but I cant remember the exact thread I was reading and if it even refered to replacement bolt on kits might have just been aftermarket larger than stock items.

Anyway thanks all for the help.
