Please take cost into consideration, I have no need to brag how expensive my rebuild was, or that my studs will support the Titanic. I just want something that will not fail, and costs the least.

Hi Mike,

I think you'll get varied opinions to your questions here so I'll simply offer mine, FWIW.

1) Personally, I'd use the late 993TT Dilavars in a mag-cased, high-HP 2.8. Mahle cylinders must be modified for these as they are slightly larger OD than the steel ones. Naturally, case-savers are always installed to properly anchor the studs and strict oil temp control is mandatory for maximum durability.

2) We like the same 993TT studs in these engines to maintain consistent head clamping forces through the range of operating temperatures.
