Well for 177HP at the wheels, its not stock. Its fully built from bottom up. I have a friend with ls/vtec built from bottom up and its just putting 161HP to the wheels. Thats with an engine management system. I can believe a Civic HB with fully built(LS/VTEC) can take a stock WRX. But just a LS/VTEC straight swap wont even touch a WRX. Dont believe too much of the hype, no ones gonna tell you what they truely got. I used to blow the doors off Camaro's, Mustang's and Vet's with my 95 Civic HB LS/VTEC(built from bottom up). But let me tell you, it took alot more than just a swap. Try something like another $5K after the swap.
