Just saying HI, I have a 1991 surf 2.4td auto ssr-x LN130 with no real mods other than the engine so far. I have just had a new head built to a very high spec and had the turbo rebuilt with a maram shaft and a few other cheeky bits as well currently running 10.2 psi with the potential for a whole lot more if I ever win the lottery and can afford the diesel!
