from what i know only LRP spec3 and spec4 is similar to IDM evo3.
Just for some info the piston/sleeve set for the IDM is the same part number for the EVO3 and the EVO4 I would assume that the only difference is that the modifications are not the same if there are any on the LRP.I have not seen one. Also there is a difference in the piston/sleeve sets between the EVO2 and EVO3 .21 engines that are labeled spec 2. They both will run but the Spec II piston/Sleeve is slightly different. Just some info.
so here is a list for the IDM brand
for the .12 EVO3,4 the same
for the .21 EVO2 and old NON SPECII EVO3 same
EVO3 .21 new part number
