Rotate your turbo housing. Its facing the wrong way. Just loosen the 4 or 6 screws holding the exhaust housing to the turbo core and rotate it 180 degrees then tighten it up. You might want to make sure you do it right though, ie your oil feed is at the top of the turbo still, and draining out the bottom. You DO NOT want water at the top. It will only fit one way so do it right coz its a bitch in the arse to keep adjusting. I got my old gt3071r the right way around first go

Pics to explain better no matter how much you rotate the exhaust housing the dump should face down on a stock manifold when you turn the housings it rotates the core you want the oil drain facing straight down

yep vlt orientation is completely different to rb20/25. mixxing manifolds and turbos means a custom dump, not worth it when you can get a stock turbo to suit for ~$300 in good condition

rotating the exhaust housing will never change which way the dump faces....

I had it wrong lol I thought he meant nothing was lining up, the we setup. When he said upside down I assumed the t3 flange was out along with the dump.

VL dump wont fit, as vl manifold faces straight down, wheras rb25 manifold faces sideways. PS ive had a highflowed vl turbo on a 25/30 and it sucked, just get a real turbo

mine is hi-flowed too. is it really that bad? was the power similar to a std rb30et?

It could have been rotated by someone.

Well I was wrong too, as Adriano confirmed the VL manifold points down, but what did you mean by being rotated? Have a hard think about it for a second.......... You cant rotate flanges on a cast iron housing mate... lol

The VL rear housing is complete with dump.. The wastegate flapper is part of the dump so its also hard to change that.

My bad tho Adriano, I thought I remember a VLT manifold looking like a RBDET one, but it has been a few years since I toyed with one of those!

    • Maybe I also should have wrote that a bit better lol. I did come 8th last in English at school during the HSC, ironically spent 2 decades reading/writing specifications and contracts in IT 😂
    • Right, but that's in-cylinder, there's the interaction between that and the TWC which complicates things. Pulling out timing to reduce NOx is a strategy I saw in transitional emissions vehicles like stuff from 1974 or so. The two inlet runner system is interesting but I'm not sure it makes a huge difference as far as emissions goes, is it a tumble valve? I've seen stuff like that even in cars from the late 80s. 
    • Hello all,   so i recently swapped out my rb20de neo with an rb25de neo( engine,transmission, wiring and the diff everything) but i just cant get the gear indication light on the dash to work when i switch to tiptronic mode. Note there is a steering wheel switch beside the shifter and i dont have that. I did notice yesterday while switching to tiptronic that the indicator on the dash started to work but it didn't afterwards. Does anyone know how this actually works? Or do i still need that steering wheel switch to be connected and on for that gear indicator to work?
    • Hence why I said earlier that I don't think the turbo Neos ever would have actually qualified as an LEV. I suspect the only actual LEVs that came out of Nissan were the NA Neos. Still call them all Neos. They all stil have the Neo-ness. Just that they don't all qualify as as LEVs.
    • It will give gains, but you wont hit 600 It will give gains but it wont get you to 600 imo. You will also sacrifice low down and you will be adding extra volume if you port match it, more so if you port the plenum runners depending and how its done I think the only time youre going to see about 100hp gains is if the car is making well over 1k kw I do have a spare set that I was going to test with, but i dont actually think there is anything worth getting going larger. I did a fair few S14/S15 and the standard TB is fairly small, I went to 60 and in some cases 64mm which is significant over the stock unit. You can also get some weird ratio changes. I think 20kw will be a stretch on a roller dyno. If I had it apart I might mill the shafts a little and not expect much, I think the stock size is still pretty good for a street/track car even with larger capacity. I might change diameter it if its a drag only car
