Max - I think you'll have problems trying to run 10.3:1 compression on 93 octane gasoline. Nux lives in Europe, and they have (or had in the 1980s when these engines were built) higher octane gasoline readily available. This engine doesn't have a knock sensor, and can't detune itself after sensing knock when you put the pedal to the metal.

If you aren't driving the car on the track, don't worry about the stock rod bolts. Yes, if you do replace the rod bearings it makes sense to use ARP or some other stronger bolts. But you don't hear of a rash of stock street motors having rod bolt failures. You don't need to run over 6,000 rpm, and typically in normal driving you don't get above 4,000.

If you change rod bearings without splitting the case you can't use the stretch method. But torqueing to ARP specifications works, as does using the factory torque and angle method. You just have to do it right.

I'd go with just stud replacement.
