Overview One of the most popular upgrade engines for the HPI Baja series and the Losi 1/5 scale trucks/buggies. Zenoah engines are the best in the business and only use the best materials for their engines and components, all their engines come with a Walbro carburetor and an NGK spark plug to complement their engines and ensure they run at optimum performance.
Do keep in mind that for most (including all the models listed below) RC models you will need to install the standard air-filter and exhaust (that came with your RC car).
Losi 5IVE-T | Losi DBXL
You will need to use your clutch mount and flywheel cover from your old (stock) engine for correct installation. Everything else should bolt up nicely.
TLR (Losi) 5IVE-B
As you cannot use the stock clutch mount or flywheel cover like you can with the Losi 5IVE-T & Losi DBXL (as it doesn't come with one) you will need to purchase this shorter clutch mount and a Rovan flywheel cover or the Hpi flywheel coverseparately for a correct installation.
HPI Baja 5B | HPI Baja 5T | HPI Baja 5SC
We recommend purchasing this shorter spacer (alternatives: HPI-102164, HPI-87458 & HPI-87571) for a correct installation (the Zenoah clutch mount's mounting stud is too long). Everything else should bolt up nicely.
Recommended petrol: 95+ Octane
Recommended fuel/oil ratio: 25~40:1
Clutch Engagement: 6000 RPM (STD Spring)
Carburetor: Walbro WT-990
Spark Plug: NGK CMR7H
Engine Horse Power Comparison
To help with your decision of choosing a new 2 stroke engine for your RC car (whether is it a HPI Baja, Losi 5IVE-T, Losi 5IVE-B, or another 1/5 scale RC car) we have gathered all the horse power ratings to show you the difference in power.
