Im looking at changing out the roller rockers on the A15 to get a little more power and better for some high RPM.

Part No.YT 6023

Just enquiring if anyone is running a set of the yella terra rockers Modular shaft type with shafts and pedestals included. which would be a 1.55 ratio. (stock 1.44 ratio??)

Im assuming the part comes with the push rods (shafts)

I have sent yella terra an enquiry email regarding the part but im just wanting to your take on the rockers itself and what gains i will get from the kit?

The kit doesn't come with pushrods, you will need to have some made up. ball at both ends in comparison to ball and cup [datsun std]

Ahh that sucks :(

Any idea of some company's that would already have some premade one's?

Or someone that could make up some pushrods, because to be totally honest i have no clue where id go to get some push rods made up unless i can get a metal fab place to CMC some out, not that im sure of the size of the push rod and what size it would need to be with the kit.

Cheers dave :)

I've got a set of the JB Racing rollers that I bought off PJZ. They go straight on the rocker shaft and have the added bonus of being a 1.65/1 ratio so one can achieve some serious cam lift.( I ran this past my camshaft supplier first and he was all for the idea of a bigger rocker ratio)No hassels with pushrods and they are a quality product. I would thoroughly recommend them.

i have a meter of blank YT roller rocker
alloy extrusion in the shape of a rocker
yet to be cut up and milled

The JB rockers that b110sss is talking about are only roller tip (on the pushrod side) and the side that goes on the rocker shaft is bushed. Well that is how my set is which I also purchased from pjs. Still ment to be better than standard especially if the engine is high revving. Yella terra is the way to go if you are chasing Hp

You can get the pushrods off the shelf. The set I have are Crower brand from memory. I can give you the part numbers(to suit a14/15) if you go with the YT rockers.
