As the low ETS are becomming more and more to keep up with these jap cars. I own an 87GN i want to put cars into mid 10's safley. I do not want to hack car with roll bars and 20 gauges. Stage 2 is very expensive and very hard to find virgin blocks. The stock block can handle it but for how long and what needs to be done on the stock block to produce this kind of hp? what should be expected from ta performance? is it worth the wait?
