i saw in these forums a few months ago a guy had turboed his stock map sensored 4age, without the use of aftermarket engine management, how did he manage to get his map sensor to register such high boost?, also i'd like to know what else is involved in such a conversion, with the main purpose being more power rather than longevity of engine/gearbox/drivelines etc (20v front cuts are getting pretty cheap ) any advice in regards to a good/cheap low boost friendly turbo, and manifold fabrication options, thanks for any replies:
