After a discution with my tuner, he recommended a little recipe for ~200HP (@crank) on AFN.
He gained 197Hp and 415Nm(on dyno) on a Golf 3 AFN with stock internals. As I have the original AFN engine block on my garage, I want to rebuild it with PD (or maybe ASV) pistons and Pd100 rods. As I saw, the stock internals are ok at ~200Hp but I want to drive without fear to brake something.
As is a little hard to find 11mm IP from AHH, or the AHH bracket for it, and after that the entire transmission system with pulleys(crank,IP, camshaft) because the belt for AHH with 11mm pump is wider, can I use 10mm with bigger nozzles and the same result or should I seach 11mm pump and the other things?
For the moment I don't want to modify the head, just new hidraulic lifters (any suggestions?).
Now, about pistons, what to be,used (both) AWX 18.5:1 CR or ASV 19.5:1 CR (with better oil cooling), both 79.5mm with new sealings (stock size), honed cilinders for new facing, not rebore, and new bearings for crankshaft. That engine was running very good even in winter despite 300k km on it so I don't think I will need rebore and bigger pistons. I prefer used pistons and rods because the low price, otherwise ASV or BGW, BHW new pistons but very expensive.

PD130 pistons with ATD, AJM (pd100-115) rods (to get)
maybe EGT and boost gauge
I know that maybe the whole story was discussed before or fragments but maybe I will get new opinions. I like the ASV pistons, looks nice and for sure better cooling, but for that power is not more healthy a small CR, like with AWX pistons? If they are good for 200Hp on AWX engine, I think they will do the same thing on a AFN.
