I have a shop in Poland making some brackets and other parts for a ax1200 Whipple Supercharger I am now building after getting what I wanted from my M62 kits both of which I have sold. Early this week I was talking to the guy in Poland as he was chasing down a 1.6 liter Fiat E-TorQ head that he was pretty sure would work on the Tritec. This is not a r50 Tritec with a ported head but rather a Fiat 1.6 E-TorQ engine. Fiat purchased the Brazilian Tritec plant in 2011. The Chrysler Engineer that was involved in developing the Tritec had this to say. This is the 1.6 E-TorQ head sitting on top of a r53 Tritec head. This head bolts right on the Tritec with the valve cover, cam, cam gear, rockers, timing chain, and intake manifold also bolting up although the intake manifold does need to ported out. re Through some Fiat contacts in Europe it was determined that the 1.6 uses the r50 crankshaft. Through pictures I found it appears the 1.8 engine uses a Siamese cylinder insert that eliminates the water port between the inner cylinders thereby allowing the use of the 1.6 block casting. This would mean the r53 crankshaft would work and that with the Siamese the engine could accept supercharging via forged rods and pistons. The 1.8 does not appear to have the proper bolt holes for the attachment of the supercharger snout. Both the 1.6 and 1.8 share the same stroke as the Tritec with the 1.8 bore increasing from 77 to 80.5 mm. I have reached out to Wiseco and CP on if they would make a MINI piston in this 80.5 bore. With the r53 crankshaft, forged rods and a 80.5 piston the only items remaining are confirmation of the transmission bolt lug spacing and the spacing of the timing chain/oil pump cover. Fiat uses Aisen transmissions and as the Tritec used both Aisen and Getrag the possibility is strong that the Getrag will mount to the E-TorQ. The 1.6 head should have different type valves installed to handle forced induction pressures. The head was successfully installed on a r53 and will be flow bench tested once valves are changed over. The 1.8 engine is used in Latin and South American where in Brazil it is an alcohol engine. I have found new short blocks for a little as $1250 US that does not include shipping. The Fiat/Tritec/E-TorQs have been out since 2012 and it is surprising that neither of these possible mods were ever attempted. Alejandro's comments are positive relative to the head and it appears this could be a low cost alternative to a "worked" MINI head. If you are interested in more information send me a PM.
