Had a Kyosho neo 3.0 with this engine in and was very surprised and loved the sound of this engine always starts first or second go and she sings nicely on idle and is so easy to tune got this one on clearance and dropped it in a truggy plenty of power and low end torque to move the truggy without any problems! definitely recommend engine can’t fault it!

Rich @ Wheelspin Models
Could you please recommend an engine that would be better than the one that already comes in the kyosho neo inferno 3.0
Spencer / 14th June 2024

If you are racing .21 is the maximum but if bashing then this would be amazing SCH-LRP32803

Steve @ Wheelspin Models

Tony Hilton / 1st March 2024

Steve @ Wheelspin Models
Could I put this in a ftx carnage nt as a replacement for stock engine and is it a straight swap
Trevor England / 10th February 2024

No, this is a big block engine so to big for that car.

Si @ Wheelspin Models
what the difference with the SP and the R version is the SP an upgrade to the R ??
Richard Cliff / 19th June 2022

The R was made by different factory to the SP.

The SP is very good, very reliable very few issues. but same basic specs.

Si @ Wheelspin Models

Steve W @ Wheelspin Models
Hi should this engine have a running in ring for the carb mine hasn’t
Kevin Hill / 18th June 2022

Kyosho engines do not usually come with one , it is usually only with hobao engines.

Steve W @ Wheelspin Models
What glow plug do I need for this (running 25% race and RTR)
James / 18th December 2021

This would work for you HPI-1502

Si @ Wheelspin Models
Where is it made?
Ely Simon / 22nd September 2020

Sorry I'm not sure on that...!

Ben @ Wheelspin Models
could you link a replacement clutch for me as i need a new clutch and bell for this engine.
Max Rackstraw / 4th July 2020

The clutch depends on the car rather than the engine. But something like say AB-2300007 would be a good starting point

Ben @ Wheelspin Models
Have an old Kyosho 7.5 with a GX 21 engine, would the GS 21 sp be a direct replacement engine? Thank you
James Steer / 15th June 2020

Yes, that should bolt in

Ben @ Wheelspin Models
Hi I have a lnferno mp9 with a ke21r engine in it can I change it to the ke21sp Many thanks
Kevin Hill / 7th May 2020

Yes that would fit

Ben @ Wheelspin Models
Hi, I bought an old Kyosho inferno mp7.5. the engine had seized but it had also been damaged with shards of metal inside, will thus motor slot straight in to my model?
Neil Mcnicholl / 21st December 2019

Yes, this should work fine in an MP7.5
