John's JDM Honda K24A 818R Rebuild

[Hobby Racer]

This is a continuation of a build thread I started back in 2017 where I documented the initial build of my 818R using a Subaru EZ36 flat 6 engine. To see anything related to the first build of my car with that power-plant please check out the thread listed below. Please post any questions about the old build in that thread.

John's EZ36R H6 818R Build

This thread, however, will document the change over from the Subaru H6 engine to the JDM Honda K24A High Performance inline four cylinder engine I have chosen going forward.

For those who have not seen the car previously, here it is.





And here is the new engine I will be fitting into the chassis. It is a JDM Honda K24A high performance engine featuring the iVTEC system which has variable timing control on the intake cam PLUS dual lift profiles on both the intake and exhaust cams. Factory rated at 203hp @7000 rpm, this particular engine most likely came out of a 2008-2013 Honda Odyssey Absolute. I know, only the Japanese would put a performance engine in a mini van!

In any case, subscribe to this new thread to get updates about the Honda install. There will be lots of information about fitting this engine to the 818R as it is not a drop in configuration.

My goals for this project are:

• Fit the engine with minimal frame modifications
• Continue to use the Subaru 6MT transmission from the old build
• No external body modifications (I don't want to have to repaint any part of the car)
• Use my existing standalone ECU and other electronics to run the engine
• Use my existing supercharger and AWIC system to boost performance
• Make ~300 whp using the completely stock motor
• Fabricate an oil system (wet or dry) to keep from blowing up this motor
