the SP25 has become a SP20 with a 2.0L sky-active engine
also, are you getting a turbo/intercooler/exhaust upgrade with that? getting 300hp (225kw) out of a stock turbo would take a fair bit of work...
17 psi with just intake/DP gets ~205, 15.5 psi with intercooler/DP/intake is ~215kw
even people who have put 18psi through their engine with a turbo upgrade are only just cracking 300hp

actually, looks like the SP20 is a new model, whilst the SP25 continues with the same engine
