hi all,

cause vl turbo parts seem to be cheap sometimes i figured i'd ask this one...

is the rb30 exhaust manifold the same bolt pattern as the rb20/25 one?

can i use the vl t3 turbo as an upgrade on the skyline? and can i just buy rb30 extractor gaskets instead of ordering in the rb20/25 ones?

thanks all in advance :)

manifold stud pattern is most definately different and the turbo mounts at a differnt angle as well.

No they are different,some of the holes are turned around the other way.

Yes,but a Hi-flow one would be better.Or if you have a RB20det or RB25det turbo hi-flow that.

and can i just buy rb30 extractor gaskets instead of ordering in the rb20/25 ones?

Not to sure about that one

Due to the stud pattern being different the gasket wont fit up directly. However if you are in a bit of a hurry and cant be bothered sourcing an rb25 gasket, get some tin snips and cut the vl gasket into individual port gaskets. Then get a metal punch and elongate the circular holes into longer ovals, this has to be done due to the different shape of the ports on the 25. Its a fair bit of stuffing around but its not hard...

Hope that helps

Cheers

      If doing that ^, I'd take the idle up valve out and plug the hole in the pump.

      You can try capping the power steering idle up valve at both ends if it's old. The valve and the intake manifold. That is something that is known to fail in Toyotas with age and it will suck power steering fluid into the intake and burn it in the engine which can cause issues. Then bleed it again with engine off first. Do like 30+ lock to lock turns with the front wheels off the ground.

      Update:   smoke test all pipes no issues cleaned reservoir   fluid put in ( dexron 3 atf)   steering turn side to side and could hearing  gurgling from steering rack which I assumed was air lock, opened one of the steering rack connections and could see loads of air getting pushed out( not sure if you meant to do that / whether it will re introduce air into system)   anyways, loads of side to side sound was gone. Turned car on, pump was slightly ( barely) wining so turned side to side few more turns and fluid level when car on was almost none in resorvoir which I guess is normal if car is one. Turned car of and fluid was gushing out. Almost 200-300cc was pushed out. Repeated engine off side to side followed  by engine on and same result       going mad now. It seems system is either sucking air in whilst on or there is tons of air which I am not giving it enough time to bleed. Thoughts?   would it work like brake caliper if I open steering rack copper pipes and let gravity pull all air out?   or maybe have a restriction somewhere? What is the red circled item, could that be blocked? It i
