hi, ive done a search but cant seem to find what im after.
im looking for a bit more power from the tds lump and have already increased the boost to 17psi but i have no benchmark as to what the stock boost is?? i would hazard a guess at 12-14psi?
also, what sort of boost can /has been run on theese? diesels are generally pretty tough bottom end wise but i have read about the m51 having head cracking issues with boost increases. whats the highest boost that anyone knows has been run??
also has anyone ever upgraded the turbo? the stocker pulls strongly from around 1500rpm but feels a bit restrictive at high rpms. id sacrifice a bit of lag for a slightly bigger turbo and more outright power from say 3 to 5krpm.
any info much appreciated
