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.

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

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.

.28 is the biggest anyone tends to put in those like this
Answered by: Steve @ Wheelspin Models
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

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
