Just wanted to share my pride and joy with all you guys here at ek9.org forum as we all love our builds.

Bought the dc2 with the k swap from a fellow civiclife member back in September and previous to that was an ek9.org member....

Cars had loads of small mechanical and electric issues which for others would be nothing but for me was a big NO NO which needed sorting out.

Got to work by stripping the whole off the engine loom and interior loom and started it from scratch with no lose wires and dodge connections.

Then tlc started to the body by sorting bumper gaps and getting everything aligned and in order. In the mean time started adding some carbon bits like a oem look carbon fiber bonnet and carbon fiber front lip.

When the teg was NA got dynoed at 238bhp which was good but wanted more power. Credit card came out so went and bought a tts supersport kit with oil and intercooler and the build started....

320bhp (270whp) & 215ftlb at just 8psi.
Having a walbro 450lph fuel pump fitted next week and have another dyno to get the boost up to 11-12psi to achieve the 350-360bhp mark.

Finished my last tweak today. Walbro 450lph got fitted and got the car remapped. 332bhp (283whp) at 11psi and we got loads of wheel spin on the dyno. Couldn't keep all the power down. Really happy with the results. An absolutely animal in every gear.
 
Such an awesome car. I'm guessing it fair shifts! Good job you have the a048 tyres on order to get some traction :drive:
 
Excellent work, car looks great. Fire a few videos up when you get a chance :)
 
Do you have an ETD? Really helped my DC2R to stop wheel spin + hop, but that was a mildly tuned B18 - was running Hankook RS2's also.
