CT Engineering Supercharged FD2
Saturday, May 15th, 2010CT Engineering has been selling supercharger kits for Acuras/Hondas for a long time. However, they did not have a complete kit for the JDM FD2 Type R.
We got them to send us all the parts that they had to fit on to all the different models of the Acura/Honda K series engines. Items like pulleys, tensioners, belts, for K20, for K24, etc. So we had all the parts, be it from the RSX, TSX, Civic Si, etc to ensure that we will at least have as many parts as we might need to complete the installation in the JDM FD2 Type R. There is no kit offered for the JDM FD2, so we just wanted to make sure we had everything.
Here is a breakdown of the parts that came, it is really complete; Belts, OE Gaskets, hoses, charger, bolts, pulleys, etc. CT Engineering even included a set of brand new IK24 plugs from Denso.



Instructions from CT Engineering recommended that we crush the fuel pressure regulator in the fuel tank so that we can have more pressure/fuel. However, as I wanted this whole setup to be completely reversible, we went with a slightly bigger set of RC engineering injectors and left the fuel pressure regulator alone. After the tune, we realized that there was sufficient fuel supplied from the factory fuel pump. Exactly what we wanted.
As this supercharger kit does not come with any aftercooler, we decided that this engine needed the neat setup from AEM water/meth injection kit would aid in the cooling of the charged air. This has been tested and proven on many other cars that we did. In addition, the stock engine on the FD2 has a factory static compression of 11.7:1. That is really high for forced induction, and we needed to have the coolest intake temperatures to keep any detonation at bay and also make better power! We normally used an output on the KPro to run the water injection system. That way, we are able to trigger it base on RPM, throttle position and also boost levels. However, as the flashpro does not have any external outputs yet, we were left to run it off the stock AEM controller simply based on boost. It works fine, just that I would have preferred the pump to come on based on the RPM vs Boost setting for a finer control. I am sure in future, Hondata would be able to incorporate a feature like that in the Flashpro as they already have a PWM control now for boost control.

This car has Hondata Flashpro in it, and it worked like a charm controlling the larger RC Engineering injectors. they idled perfectly and were easy to tune. We managed to get 262whp on the heart-breaking mainline dyno… a regular FD2 type R normally musters about 180whp on this same dyno with an intake mod.
As mentioned, with the high compression NA engine. Utmost care was taken while tuning this monster. Timing the water injection right, choosing the most suitable water jets, VTEC engagement points, variable cam angles, appropriate fueling for the right air fuel ratio, spot on ignition timing were all contributing factors to a perfect tune on this engine. The tune was just like having all the perfect ingredients put together by a Michelin-starred Chef. Simply delightful to drive and never fails to put a smile on my face, not just when giving it my all, but even for the daily drive around town with its immensely higher amount of torque from the get go.
Dyno chart comparing between the Supercharged product vs a stock FD2 with an aftermarket intake and exhaust.

It can be seen from the dyno chart, there is a 82whp difference at the peak power! Power was also higher everywhere else in the rev range.
Having driven and been modifying many cars previously, I have to say that this is one of the most value for bang mod I ever did. The gains and drivability obtained from this exercise is definitely worth the price tag that accompanied it!
I have to say the mechanics did pretty well as we got all the supercharger bits installed on the car in just 1 day, and just another day to get the water injection fitted and Hondata tuned.
