datto13b, you do actually realise that an SR will need the exact same mods as the CA to get to 180rwkw, they have 144kw at the fly stock(s13) so they also have a fair way to go
and with a stock SR there is no guarrentee that it also wont just spit a rocker or something like that and its not like an S15 engine is really cheap, being double the price of a CA wouldnt surprise me
