Old Gregg said: Yep, me too. Amazing work and dedication, OP, I'm looking forwar to following this. What does CDS stand for though?Thank you. CDS = Cold Drawn Steel. It's stronger than regular hot formed/rolled steel and is usually the material of choice for Roll Cages.

Greg_D said: Hi there OP/max torque,sorry for the thread hijack.but you both clearly know a thing or 20 about zetec's. i have a silvertop zetec 2.1 (calibra turbo pistons) that has had a light rebuild, i am running FRST inlet and ERST T3 turbo and 600cc injectors, running emerald ecu head is mildly modded ~(standard valves i think), i am about to go and get it tuned/dyno'd, what sort of power do you think that sort of setup should reasonably be able to produce/sustain?Hi there, If it's a regular T3 (.36 housing) then 11psi is the safe limit, and I would expect 250bhp at this boost pressure from your provided spec. There are however some considerations:1) Using boost pressure as a (very rough!) guide, the standard valve springs can support a maximum of 10psi due to the elevated cylinder pressures resulting from forced induction.2) As you don't mention rods, I'll assume you're using the standard items with the wrist pin bore enlarged to suit the LET pistons. The important factor here is ensuring that the power output is limited to ensure the standard rods won't break; 260bhp (using BHP as a rough guide) is a safe limit for the standard cast rods, regardless of whether they are shot peened & have ARP bolts. Thanks,MarkEDIT: I forgot to add that those injectors are on the large side for your spec. I don't know how good Emerald is in terms of resolution, but to be on the safe side for a better idle you can trade down to something around 440cc.Edited by mwstewart on Monday 14th March 14:07
