T28/1GGTE...oil pressure?

[amon]

Heya fellas,i am using a rebuilt T28 A/R60 front .60 rear on a steam pipe custom mani on my 1G.(gen3)
First question are they oil pressure compatible?(restrictor?)(overpressure???)

Second, the car(RA28) is running stock ecu, 3 inch dump, fmic and pod so with that in mind what sort of numbers/spool times could i expect from this turbo.
The turbo came off a 94 200sx

Anyone????or do i smell

This has been covered before regarding oil flow rates and turbos, I think there was a thread only just last week.

My T28 is fed oil through a 1.5mm restrictor and this has worked fine for me for many years.

Do some searching on here and the net and make up your own mind on what size restrictor you want to use and then check that the flow rate is compatible with your particular turbo (again search and this info can be found the flow rates are usually stated for bush and bearing cores with bush requiring more oil flow).

Good luck.

youll basically get the same amount of power out of it as you would on a sr20
e.g with bolts ons you may get 180rwkw when its pushed hard, or the stock computer may lean it out and youll do a piston. to many variables really. id like to har what power it does make when you get it dynoed.
and yes youll need the 1.5 mm restrictor for a garret bb turbo, and yes you do smell a bit

Thanks chaps for the input i will search again,and i will post my results when Dynoed.
YLD16L you used a 1.5 mm restrictor that sounds really small,i just hooked it up straight and it spewed oil into the exhaust so assumed the turbo was cactus so i got it rebuilt.
Lucky i did in the end cause it was all gunked up with crap.
Celicapain; the turbo is not a bb but alas a bush one,180kw would be plenty off neddies(hp)
for me.
I will post my dyno results when its done.

It does "sound" small but I tried no restrictor, 3.5mm, 3mm, 2mm and 1.5 to get it right. Whilst I did use a 1.5mm drill bit to create the restrictor it was hand drilled so the actual hole diameter is most likely somewhere between 1.5mm and 2mm. That prduced the correct flow rate for my turbo on my engine. Yours may be a different but it wouldn't be by much.

It's surprising how small a hole they need to be happy. From memory, don't the Nissan turbos like this have the restrictor built into the banjo bolt supplied by the factory?

[YLD-16L]

Correct Shinny, and on some of the BB cored turbos it's not uncommon to see an orifice of less than 1mm in diameter.
