I've been contacted by Matt (Shik) about the possibility of designing camshafts for the Legacy Turbo (EJ22T) models. As you might be aware, the cylinder heads are an issue with these engines, and replacing them with higher flowing heads from a WRX and/or EJ25 would be beneficial.
Nonetheless, I'm willing to help work with you all to design a camshaft that will take maximum advantage of the cylinder head flow we have to work with. What I need to know from you all is:
1) How much interest is their in such a product. Cost will be similiar to the cams we offer for the SOHC EJ25 ($650).
2) What boost levels do many of you run and do any of you have backpressure per boost ratios for the turbos you use? (ie: stock turbo, 14psi boost, 18psi backpressure between turbo and exhaust port)
3) How critical is idle quality? Do the turbo legacy's have decent idle control/bac valves?
4) What max RPM do many of you rev to?
Sorry for my ignorance regarding the Legacy turbos, I'm not an expert by any means on these models. I am, however, interested in helping you all in your quest for more power.
I will also need to have someone volunteer for testing the camshafts. Someone will need to have the means to dyno before and after.
Please feel free to continue discuss here publically, so we can hash out the details.
