HPI Nitro Star F5.9 Engine With Pullstart

Brand: HPI

Part No: HPI-117259


SORRY, THIS ITEM IS DISCONTINUED AND NO LONGER AVAILABLE.


Why not contact our team to see if an alternative is available?

The HPI Nitro Star F5.9 Engine With Pullstart (HPI-117259) delivers huge torque and eye-opening acceleration for 1/8-scale big-block vehicles. With nearly 4hp on tap (3.76 PS), this 5.9cc powerplant is built to launch heavy rigs into wheelie-popping performance and serious top speed.

Starting is simple thanks to the integrated pullstarter. A robust one-way bearing housed in a large 14mm hex boosts durability for repeated use. For those who prefer push-button convenience, the F-Series HPI Roto Start engine starting system can be installed as an upgrade.

Its big-block layout and 8.5mm carburettor make tuning straightforward for powerful, consistent running. The engine is specified for a Cold R5 glow plug (HPI #1504), aligning with its high-displacement character for strong mid-range punch and reliable hot restarts.

Standard Parts

The F5.9 engine is a huge powerplant with eye-opening acceleration and ground-tearing amounts of torque, capable of powering your Savage up to ludicrous speeds. With nearly 4hp on tap, it really is true that there's no replacement for displacement!

The F5.9 engine is started by an easy pullstarter system, with a one-way bearing encased in a large 14mm hex for increased durability. If you want to upgrade to even simpler engine starting, just install the F-Series HPI Roto Start engine starting system for push-button mechanical engine starting.

The F5.9 will fit right into any 1/8th scale big-block chassis, such as the Trophy buggy or truggy, or the Savage X, for awesome wheelie action and roost-tossing wheelspins!

Hello is there anyway to fit this engine in a firestorm 10t if you can’t please explain why
Tristan Fish / 31st January 2023

No there is no way this engine would work in that car,  The engine is simply a much larger engine and would not fit in the space provided by that car 

Si @ Wheelspin Models
Hi would this fit in a hpi firestorm 10t
Tristan / 29th January 2023

No, you would need a small block engine for that car, so something like this HPI-107824

Gabriele Bovo / 9th March 2020

HPI don't quote an RPM limit for this I'm afraid...

It should work well in most truggies however!

Steven Marchant / 8th December 2019

Yes, the 5.9 would fit that no problem.

The electric starters for these are the HPI-87130 or FT02623F

Ben @ Wheelspin Models
What items would I need and you recommend exam (clutch&bell exhaust main parts)
Andrew Robinson / 10th November 2018

That would depend on what vehicle you are fitting it into, as the exhaust and clutch etc are usually vehicle specific.

Ben @ Wheelspin Models
Would this be a good upgrade for the hobao mt as keep having issues with the turbo plug leaking
Andrew Robinson / 25th October 2018

Yes, the F5.9 is an excellent engine with strong power and torque figures, so should be an ideal upgrade for your Hobao.

Ben @ Wheelspin Models
hello, would this fit ok into a losi eight truggy? if so is it a better engine than the dynamite big red?
Neil / 1st August 2018

Yes, it would fit your 8IGHT no problem.

It's down to personal preference but yes we'd probably side with this engine between those two.
