VG30 turbo upgrade for RB20DET

[HRthirtyone]

yea i wanna know too.......

[R32-GTS]

Don't bother . I did thhe vg30 swap onto my r31 rb20 and it wasnt that great. A hi flow is much much better.

[DCIEVE]

what are the general specs or your hiflow simon? do you have a t3 hiflow comp wheel or a t4

[R31_GTSX]

can anyone answer my question? has any one done the conversion or what?

[R32-GTS]

My hi-flow uses a Sierra cosworth inkenel one piece rear wheel with a t04 v-trim front wheel. Its in the stock rb20 housings.

The vg30 turbo will fit straight onto the r31 rb20det with only the outlet pipe on the compressor housing needing slight modification. Or u just use the outlet pipe off a rb25 turbs.

[R32-GTS]

I missed something. If the vg30 turbo u got is ball bearing then u need to change the bango fittings to a larger size also, if its not ball bearing no problems .

Thanks r32-gts

So can i use standard r32 oil and water lines?

The rb20 that i've just got has a T3 on it from a FJ20turbo and it is only oil cooled... and the other banjo's on the block are plugged up.

So i need to know if the 32 lines will bolt straight up. Its not a ball bearing one.

Thanks again

Also i have another question..

i think the existing lines have been modified to suit the turbo that was on it..

What runs through the line that runs from underneath the plenum around the back of the motor to the turbo on a standard setup. Oil or water?

Any more answers would be greatly appreciated!

looking to get the zed up and running this weekend.

That is the water line.. I changed to an RB25 turbo last week... good fun . Im guessing you mean the line that runs under the exhaust manifold onto the back fo the block

[Clint32]

One water line comes from the back of the engine, the other goes into the block near where the oil pressure line comes from. Hope that helps.

[R31_GTSX]

haha it does help ..... but it doesn't..

I thought that was what was meant to be coming through that line.... but in this case its not... theres oil coming from that line. So its been modified to suit the turbo thats on it.

OR

It is a ECCS red top ... so would this be different to the silver top?

I can see this being a PIG of a job!
