Installing hks2530 to rb20

[Gts-t]

hey sau,

need to ask a few questions to those who have fitted hks 2530's to their rb20's

As i bought my turbo second hand it did not come with any water or oil lines, the stock oil lines line up i am able to use them but the size of the banjo fitting on the water lines are larger than the ones found on the 2530!!

I am thinking of using either some braided line and earls fittings etc but am unsure where i can buy these (i am in Brisbane) can anyone help

OR i was thinking of cutting the existing water pipes and re-brassing the hks banjo fittings onto them. What should i do, i spose either would work but honestly id rather get some braided lines made because thats what the serious builders seem to do.

The next thing i am concerned about is the banjo fitting that supplies the oil to the turbo, it seems to have and extremely small restrictor in the bolt(thingy) much smaller than the stock turbo uses. it is about 2mm in diameter. can anyone shed some light as i really dont want to shag my turbo due to something so basic as incorrect oil supply to the turbo. the restrictor came slightly screwed into the turbo core so i am assuming it is the correct one but yeah need to be sure.

All advice will be much appreciated but please no speculation just fact because this is something many people will need to know. cheers

I would also be interested in this but for RB25. Are the oil and water lines to RB20 the same as to RB25 in standard form?

26GTS, does the stock dump pipe fit? What about the pipe between AFM and turbo? Pipe to intercooler?

Sorry to hijack...sort of on topic....

SeriesII: The turbo is a bolt on meaning that it can use the stock dump pipe and all original piping etc. it is designed to be this way being a BOLT ON kit. not sure about the water/oil lines for rb25.

I'm putting on a HKS GT2535 turbs and know what you mean,what did you end up doing.Mine did'nt come with no oil lines so i don't know if they had a restrictor,anyone know???

[DCIEVE]

ball bearing so should have a restrictor. cant member what the flow rate is meant to be for bb turbo's but best to measure it prior to running

My 2530 came with the restrictor... its is smaller than the standard one is.....

I had new braided lines made up for the water by enzed.. they come out to your workshop to do it too..

was a few hundy tho, but quality costs..

good luck...

The 2535 has a small very small opening in the core,is that all the restriction it needs?if the actual oil feed line needs a restrictor in it self could it restrict oil to much?

Yep Enzed or Pirtek can make up the lines. When installing a new/replacement turbo the oil feed line should ALWAYS be replaced with a new one. Any warranty will be voided if you don't. Be aware that 9 out of 10 braided lines are illegal for street use, and are an unnecessary expense. Any brake shop can fabricate solid tube lines which will save you $$$.

Hope that helps ya !
