Wastegate actuator

[machg]

Hooray!

Got a 2nd hand RB20DET turbo for my L20ET today (much thanks to blind_elk). It came minus the wastegate actuator, but I think the one off the L20ET turbo should be able to be used. The turbos look very similar externally. The first problem I can see is that the actuator receives boost from two points on the compressor side of the L20 turbo, but I can only see one point on the RB turbo. Given that the actuator receives boost at one point when used with the L20 (it "T"s 2 to 1 the L20 turbo boost points), can I just run one pipe straight from the RB boost point to the L20 actuator?

I know I will have to be pretty careful that the set-up works properly before installing the turbo, so as not to have overboost or chronic wastegate creep/bleed

but I know how the actuator works and my skyline still has the "fail safe" valve fitted to the inlet manifold, so I reckon I can sort it myself. Can anyone see any other potential problems?

Cheers,

should work pretty well as far as i can see...

but if you blow it up, I dint say a thing

Is this a dual port actuator ?? your post is a little confusing :confused:

The actuator itself has one inlet for boost, but the L20 turbo housing has two outlets for boost, whereas the RB seems to only have one. If I had a digital cam it would help!
