What Standard Nissan Turbo Will Direct Fit On Rb30?

[humz]

need to change the turbo on my vl.

i cant find a standard vl t03 turbo (if anyone has a good one let me know)

BUT i can get rb20 or 25 turbos easily..

NOW i need to know if the standard oil and water lines and banjos will line up EXACTLY???

i dont want to go after market turbo coz i dont want a new dump and lines made up.

thanks

unless you put a stock vl t3 back on there you will need to get custom lines made up and custom dump pipe.

twin cam rb turbochargers will not direct fit to the sohc engine and are a bit on the small side anyway.

If you give me an idea what you have ATM I may have some ideas .

The only unique things on a VLT's T3 turbocharger are the compressor and turbine housings , at a pinch you could use the 0.63 A/R turbine housing from an early FJ20ET because they are almost identical (they have the 02 probe in the housing instead of the dump like a VL has) .

The cartridge (center housing and wheels) uses a common Garrett T3 water cooled bearing housing and the comp wheel from memory is just a 50T T3 . If you can get housings the rest is easy .

turbo on there at the moment is the standard T3 vl turbo.

i need to know what other turbos (such as the rb20 or 25 t3s in particular) will fit DIRECTLY with no mod to lines or dump.

i pulled the blown vl turbo off today, from what i can see the dump is different to the 25 turbo, BUT the lines look exactly the same and come from the same/ similar location on the block and back of head.

so far im assuming the 25 turbo will bolt up to the manifold (obviously), and the lines should line up, but i will need a new dump made.

as for a 20/25 turbo not being big enough, thats not a major problem as i rather have the car running than not running, aand when i find a vl t3 i will fit it.

does anyone have actual experimental evidence with this situation, my searches have not been successful any help asap would be great

thanks

so anyone tried to put a 25 turbo on a 30, does all the oi and water lines line up???

found a 25 turbo cheap and already have a dump and front pipe just want to confirm this

[discopotato03]

I'd just go to Garrett and buy a new cartridge , slap your undamaged housings (provided they are) back on and refit it .

Twin Cam RB's don't use T3 turbos so without mods they aren't going to fit like the factory spec T3 does .

I think it would be a big step backwards using the smaller turbo on an RB30 and it would choke on it - IMO the Hitachi on an R33 spec RB25DET is really a bit small for the 2.5 liter engine it comes on .

At a pinch the turbo off a Z32 VG30DET may be passable - just - it still means a non std dump pipe and it's anyones guess if the oil and water plumbing will fit up .

If you fix what you have you know it'll all bolt back in .

if you wait i can go down the shed and have a look tomorrow and tell you if the lines will fit 100% before you remove your existing turbo.

you will need to fit an rb25 line anyway for the oil feed as it has a restrictor hole in the banjo for the ballbearing turbos.

should pick a set of rb lines for bugger all from the trading section of this forum and they will fit for sure once you rotate the centre housing to suit the vl manifold.

you said you have already sorted the custom dump pipe out?
