  • Goal: Reliable and Competitive in Door to Door Road Racing

We love how successful such a simple setup can be. This setup isn't overly complicated, there are no tricks that could lead to reliability problems. This is a setup that they just need to work every time and let the driver do his thing.





1. Engine Block

Overview

Building an engine for road racing is a little different than building an engine for drag racing. In road racing, you may be racing for over an hour at a time. That is a long time for heat to build up in parts and as we have learned from Jays Tech Tips too much heat can kill engine parts. Also, in road racing, there is a balance between power and weight that provides the most control. Too much power could make the car harder to control and cause slower lap times. So it's less about making as much as you can, and more about making the right amount for your goals. 

The bottom end of this engine has stock sleeves that have been bored .020" over and 4032 Supertech Pistons at 12.5:1 compression, but the use of a .040" thick headgasket brings the compression ratio down to 12.0:1 for class restriction compliance. The rods are a light weight Brian Crower H-Beam, and the bearing are ACL Race bearings. As you can see this is a pretty simple setup, stock stroke, stock rod length, just a slightly higher compression ratio. The 4032 pistons expand less than 2618 alloy pistons, which is important when you are racing for over an hour. The lightweight rods are a smart choice for an engine that will have to be raced like this. Since it's not making much power, the weight savings are more important than the strength.

  • Displacement: 2.4L
  • Compression Ratio: 12.0:1
  • Bore Diameter: 87.5mm (0.020" Over)
  • Rod Length: 5.984" (Std)
  • Rod: Lightweight H-Beam
  • Stroke: 99mm (Std)

2. Engine Head

Overview

The head this car runs started out as a stock TSX K24A2 head that was ported by 4Piston and assembled by JBR Engines. It uses a Drag Cartel Elite Endurance Cam and Ferrea Dual Valve Springs, Titanium Retainers, Valve Guides, Valve Seals, and Competition Plus valves. This car uses factory rockers and maintains VTEC, but the cams are degreed on the exhaust side with a Skunk2 Exhaust Cam Sprocket.

4. Fuel System

Overview

This car runs on One Ethanol 117R Race Blend E85 and because it does not have forced induction it does not need a huge fuel system. Even a set of 1000cc injectors are enough to handle the E85 at this power level. This fuel system consists of set of Injector Dynamics ID1050X injectors being fed by a Walbro 450 fuel pump through a K-Tuned fuel rail and Aeromotive Fuel Filters.

6. Engine Management System

Overview

The engine management system for this car is pretty straight forward. It's an AEM Infinity taking data from a standard sensor package and controling a factory ignition.
