I always have wanted to boost a CG13. 67kg wet with all the modern engineering features. all alloy, mutli valve, cross flow, twin cam and plated bores. Off the shelf Nismo and other tuning house bolt ons available. Tranmission is a hurdle for rear wheel drive, but not impossible. Errol from Datrats has told me on good authority that he has seen the best part of ~370HP at the fly on avgas in a VIC sports sedan. Even if the dyno is generous, it is very decent power indeed.
