Std Vl Turbo On Rb25/30

[crispyvl]

i have bought all the gear to do a turbo conversion to my rb30de with a std vl turbo and went to test fit it and realised the dump was pointing upwards

has anyone ever done this? and how did you resolve the problem.

Lol sorry just sounds funny

[BMYHOE]

do you have a high or low mount manifold?

std rb25 manifold

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

ummm you mean the exhaust dump?

thats not right.... it should be orrientated the same way as an RB25

It could have been rotated by someone.

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

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

Ah that explains it as above then new turbo or custom dump

[JonnoHR31]

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.

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

[Adriano]

It made like 150rwkw at 3500 rpm, then 90rwkw by 5500

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!

your right that does suck.

thinking of putting on an internal gate 35/40 off of a xr6 turbo and see what happens!
