I have been setting on enough euro parts to assemble another 1.9L stroker to bolt to our X 1/9 4 or 5spd. transaxles in our X . Expect at least 150 bhp. I dynoed at 136whp on the rolling road with my first attempt. I'm running a 42/82 Pittatore fast road cam and dual 40 dcnf carbs and will dyno again once I switch to the dual 44 dcnfs'. I have a nice 78.4mm stilo crank plus a set of scat forged rods. Getting a set of 87mm cast 27.5 c/h pistons soon to be fitted to the 1.6 block i have. I also have a tipo head with the larger intake valves. I have the p/n's for tty head bolts and navalineasport head gasket to fit the bill. All other internals such as aux shaft, oil pump, front water jacket cover with knob for tensioner bracket to pivot on and other items such as camshaft will come as standard X1/9 parts from your favorite vendor. The rod and main bearings are X items as well since the rod and main journals are the same. Great winter project and you could have the second fastest all fiat n/a sohc X in the U.S. Mine will remain the fastest! Lol. Send me a PM if you are interested in more info. My stroker continues to please me every time I take her out. Runs as it should have run from the factory years ago. Don't re engine your X with some other marque. Be a proud Fiat owner and run Fiat parts. Anyone can strap a K20 into their X and go a zillion miles per hour. To each their own. Let me know if you want something unique in your engine bay!
