Budget high torque starter motor upgrade for 8v RWD
Posted: October 9th, 2012, 8:54 pm
Hi Guy, I noticed there was an article the other week on high torque starter motors. I was at the time converting a tipo 16v abarth starter to fit the 131 bellhousing. I have completed the conversion and it turns over a rally spec 8v block 16v head 2ltr with hc pistons much faster than the standard starter, and that is with the battery in the boot. This is probably a 'budget way' of upgrading starters on a hc 8v block. I believe the starter will be the same as on the other transverse 2ltr 16v engines. we measured the locating diameter of the original starter and then made a suitable aluminiun ring the same outer diameter, and a slightly undersize inner diameter to fit the later motor and shrunk it onto the later motor. The top mounting hole lines up ok but the side and lower one has to be slightly slotted. Do not make the ring to deep as it will foul on the lip inside the bellhousing. A bellhousing cover plate can be used to get a rough idea of the bolt positions if placed on the motor after the ring is fitted. Ensure the motor correctly locates outwards in the bellhousing so that the pinion and flywheel ring engage correctly.
The later motor numbers were Magnetti marelli E70R14/12 and 63223432
The ring in the photo had to be modified as it was to deep and fouled on the lip inside the bellhousing, This may help someone with a hc engine on cold mornings !!!!
