Sandeep, you've read about the 94mm piston conversions for the 2l engines with the 94mm x 82mm Mahle pistons. If you use the 94mm x 69mm pistons, with rebushed original connecting rods, your stock 66mm crank, and a mild web cam, you can get 1832cc's and your 120HP, totally reliable, if you use a good exhaust and some rebild and p&p heads with approx. 40mm/34mm valves. Use your 1,7l heads, bore them to 94mm 2l specs, get new valves from the 1,8l, 4 new valve seats for the exhaust side and machining the intake seat bigger for the machined-down-to-40mm inktake valve. A set of type 1 Scat springs on chromo retainers, a Web #163 with Web lifters and the original 1,7l valve train is good for that combo. A c/r of around 8,0-9,0:1, depending on what you can and want to run, with 40mm IDF's on 28mm venturies and your choice of fan system would run. Hey, Sandeep, even the Type 1 conversion system, what I can get here for 190$ is enough for such an engine. Use it with a 36HP-style fan shroud w/o heater ducts and w/o doghouse, it's a good unit. Take a look that you get the 36HP shrouds with the correct amount of intenal vanes!
With a 316° (US 296°) Schleicher and a c/r of 9,5 I reach 132HP with this combination! A winning and cheap combo!
