yeah flange will be the hardest part i know :(

front /dump is 3 inch atm into 4 inch cat then 3.5 after cat, i was thinking 3.5 inch front pipe to cat, dump can be 3 inch it shouldn't matter whatevers easiest.

And cheers Dave I will get back to you if we get stuck on that

IMO you should go for gold. That housing is going to be awesome and your only setback is the old tech compressor.

Meaning if its not good rip it off and have a turbo place install a proper GT37 52T compressor and the surge ported cover. Bolt it all back on and WHAMO, highly speculated ultimate option!

Hell if you dont like that I'll buy the whole turbo off you!

Ok for the poor souls that rememebr this thread

well..finally got around to pulling that turbo out and now im even more confused..

Now we thought it was a 21u, because we could see a 'u' but not much else as it was fitted to the car.

It has a tag on it that has _4u on it, not 21u at all..the dash is a letter or number I cant quite read..but it definately isnt an original nissan housing of any description i know of..just looking at it you can see its physically bigger..Anyone have any ideas on this...

anyway its probably not as restrictive as i originally thought..so unless its just the old 7 blade comp wheel that is no good, I have other issues with my car all together.. :unsure:

tempted to throw a proper 3076 comp wheel on it now just to see what happens..

To assist people wanting answers using the search function.

For those that can only look at one turbo when wanting to know the differences the markings on the housing will reveal all.

The R32 turbo has 16v stamped on the compressor cover and is the only comprssor cover used on RB20 turbo's.

The R32 turbo most of the time has the smaller 16v or 04u stamped turbine housing. (some 1993 models have the RB25 21u turbine housing)

The R33 turbo has 45v1, 45v2, 45v3, 45v4 stamped on the compressor cover.

The R33 turbo has 21u stamped on the turbine housing.

The R33 turbo as stated above is larger.

Searched 04U..

Get that L2 on there before I come to Vic :domokun:

    • Yeah well per the video it took 15s for the stock unit to start up....even if I give it a few seconds discount for starting that is at least 12 sec before you get a reverse camera if you are trying to leave a park.  The android unit is way faster, but 2016 for the stock unit is a long time ago in consumer electronics
    • Yea that’s why I said ima test them with multimeter and see the reads.
    • Only at idle. Isn’t a problem when rev it seems.
    • @Haggerty This seems silly to ask, but are you confident in your ability to tune the Haltech?  
    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
