Hi All,

I found out about this via a post on FB so am new here today.
I have a 1977 RX3 with a Series 6 13B pulsing under the bonnet, I think the injectors are standard but am running a large diesel turbo, dont ask me numbers but about 14psi boost and an Apexi FC. I would appreciate info on which unit would be better for me to purchase HSF3 or HSF6 aong with the summer.
I am keen to get in on the group order and thankful for any info that will help me make my final decision.

Keep the rubber on the road
Cheers
Darren
