How do you improve an extremely good product even more? You let the experience and voices of the customer influence the design allowing the product to constantly evolve! We are proud to present the successor to the ZR.32X, which is especially popular with monster truck bashers.
The new Spec 4.1 has a new piston and connecting rod design, a competition-specific turbo combustion chamber with appropriate plugs and improved timing, the performance was further increased, especially in the medium speed range. With the new, thermally decoupled 3-needle carburetor, an even finer tuning of the fuel/air mixture is possible for a more efficient burn which results in slightly more power over Spec4. The included aluminum venturi inserts in 9.0/8.5/7.5mm make the tuning options perfect.
The ZR.32X Spec 4.1 engines come incl. a free LRP Turbo WT4 glow plug.
The Spec 4.1 was race tested by our own team driver as an assurance of real-world basher and racer’s application and tuning.

Is this a drop in replacement for my Savage X 4.6?
Asked by Ash on 21st July 2022
This would fit in that car but be aware that there would be no way of starting this engine, you would be better looking at SCH-LRP32821

Hi there will this LRP ZR.32X Spec. 4.1 Competition Nitro Enginefit straight into a habio hyper 7 if so is there any other parts I will need or if you can recommend a replacement nitro engine better than the hyper 7 stock engine thanks david
Thanks david
Asked by David Chapman on 27th December 2022
This would fit straight in to that car but the engine does not have a pull start so you will need a starter box to get this up and running.

Hello I would like to know if this engine would fit into the hobao hyper vs2 .30 also what pipes would fit and can a roto start be added ro this engine
Asked by Chris Williams on 30th January 2023
This will fit that car for you, we would recommend using the original pipe as on the VS 30 this is already a tuned pipe.
with this enghine you would not use a roto start but would use a starter box like this FAST555

Hi can this engine be fitted with a pull start back plate
Asked by Josh on 6th June 2023
You can not fit a pull start on this engine, you would need to get an engine with the pull start already on it, something like this SCH-LRP32821
