SR power seems laggy - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I have an s13 with a blacktop SR and I just drove another SR the other day and noticed a significant difference.

My SR starts to loose power around 3,700rpm. We have the same setup basically stock, but his you can feel it pull all the way up to 7,000rpm. Mine stops pulling as hard at 3,700rpm and the tone of the exhaust sounds a bit different too, sorta more Subaru-like.

I'm thinking it could be something to do with timing and/or valves. There is loud ticking underneath the valve cover starting from 2,000rpm all the way to 3,000rpm.

Can anyone shine the light on this laggy SR? It's really bugging me. I did the timing myself with the help of a very respectable guy on these forums.
