[Neven911]

Hi,
I have a 1970 matching # 914-6 I'm restoring and am at the engine rebuild stage, Over the years i've accumulated a few engine parts and would like more power than the 110Hp (When it last run the only mod was E cams). The use would be street only and I'd like it to run on 91 also I don't want to mod the 2R Case in any way that can't be reversed (bar internal changes) and it should to all intents and purposes look stock (hence using the webers) So I've considered the following options:

Option 1: Original 66mm non counter weighted crank, pauter rods and AA 86mm JE low Pomp P & C, 2.4 heads E cams, Webers

Option 2: Change to a 70.4mm crank, 2.4E Mahle 84mm P&C (which i have in my collection), Pauter rods, 2.4 Heads, E cams & Webers

The case I'd line bore, piston squirters, bypass mod, case savers (strangely already had IM bearings fitted)

Questions:

1. Has anyone got any feedback on the AA 86mm JE low Comp P&C set?
2. I have some 84mm Mahle Cylinders, would it be better to bore them to 86mm than use the AA provided ones?

Thanks for your input

Cheers Neven
