Please Quick Help With Manifold

[nissan_280zx]

I have an RB20DET.

I have access to a full stainless turbo manifold for a VL turbo, would it bolt to an RB20 head?

I searched but could not find anything.

please help out.

flatmate says no.. sorry. .thought you meant rb20det in VL ..

[Craved]

can check tomorrow for you if you like, i have a VL SOHC head sitting next to a rb25 (which is the same as the rb20)

only thing is that it could drop too far down into the engine bay since the VL motors are taller.

pm me if you cant find it or dont get an answer here, so i remember lol

thanks for the fast replys

i should not have any clearance issues as the motor is in a 280ZX, and it has a large engine bay.

that would be great if you could compare the 2 for me mate. cheers

rb30et head ...

think they are different

rb20/25 have the 2 rear bolt patterns opposite... rb30 only has 1 opposite

[Craved]

rb20/25

looks like your out of luck

you could always buy a manifold flange, grind off the other flange and have the correct one welded on..

[nissan_280zx]

looks like the manifold i have must be from an rb 20/25 then, because it has the 2 front ports bolts one way and the other 4 are opposite.

attachement doesn't work , host it somewhere else like imageshack or something.

the mainfold has the same bolt pattern as that gasket you posted, but it comes with 6 individual gaskets, and a turbo - manifold gasket.

if its the same as the 2nd picture of the flange then it'll work

oh and remember to get what turbo flange it is.. t3 t4 GT25 etc so it matches your turbo .. or you'll have to get an adapter or reweld a new flange on it

[Syphon]

The other difference also just for anyone searching in future, ports 3 and 4 have different spacings from 20/25 to 30.

So not only do you need to change the flange, you need to modify the piping to suit the spacing on the flange.

if its from an rb30et it wont fit at all

yeah i already know its a T3 flange, so all is good. might just have to get a new turbo any way tho, seeing as i will need mew oil and coolant lines anyway. see what the bank account says.
