Engine Parts and Mod Interactive Guide By Monster Sport

I come across this webpage while doing my routine browsing of Monster Sport for new parts for HT81S. This is a guide for those who would like to upgrade their engine parts, with picture and links to the particular parts. I think most of the HT81S/HV81S owners will reach more than 100k km in the odometer and most probably its time to think of engine upgrade.

I know that the performance of M15A is still adequate for the time being but a major overhaul and cleaning plus doing proper balancing and blue printing of engine will produce even better result. Since you are going to pay for the labour soon, why not buy all these parts and do it in one go.

I am very happy that Monster Sport still consider and produces parts for HT81S after this model already stop production for several years. This also means that there are still demand a supporter for HT81S in the JDM market.


This interactive guide with picture also serve well for those who would like to change their engine parts and upgrade their engine to M18 (1800cc). This will probably give you near to 180-190bhp after changing ALL the performance that is available by Monster Sport, and a big big hole in your pocket.
