TDi North cams

Since early 2004 we have been working with some top manufacturers involved with development of camshaft profiles for the Honda K20 motor. In America Toda began running a new profile called the N2 for a single class competition series and staff at TDi North were working closely in developing the ECU calibration file that was sent out as part of the Toda engine package as we were running and testing the cams here in the UK.

We were then testing some other makes of cams from US manufactures to ensure compatibility with the Euro K20 engines where we were running the profiles in our own cars competitively and feeding back our findings.

In 2011 we decided to take the step and develop our own camshafts with the goal that they would be true “drop-in” cams so retaining the stock valve-train but at the same time give outstanding performance and reliability. There are many options available for aftermarket cams but the majority require up-rating the valve-springs which with the increased costs of the parts and labour make a simple cam swap cost prohibitive to many and given that the only true drop in cams available were the pretty mild JDM camshafts from the FD2 and DC5.

The outcome was the creation of a new profile that retained the factory 12.8mm lift but with slight changes in ramp angles and duration crated a curve that was comparable with the JDM cams on low cam but exceeding the JDM on the high cam.

TDi North have now supplied over 20 sets of these billet camshafts with no reported issues and run them successfully in our own Time Attack car for a whole season.

The TDi North K20 Stage 1 drop-in cams are available at £900 per pair.

We are able to offer them supplied, fitted and fully dyno tuned for £1500
