Hi,
Nearly ready to get my old modded K03s and ported OEM manifold back into the car. Where im confused is that a german torque spec list per bolt size that we have at work says 10mm bolts in that pitch should be 43Nm fo 88's, 63Nmfo 10.9's and 74Nm for 12.9 high tensile which is what the VW bolt are. So why (admittedly on vortex) am I seeing figures of 26lb/ft (35Nm) being kicked around? Anyone know the official spec?
Also exhaust mani to head nuts- I've found 25Nm. sound right?
