Knightshade Posted June 16, 2008 Share Posted June 16, 2008 i installed cold air intake, greedy sp2 exhaust, beside, turo/supercharge, what else can i do to add more power? Given there are no turbo kits for the car, and the only supercharger kit left on the market doesn't work on the US spec IS350 (TOMs kit requires a JDM ECU), you didn't have much options there anyway. If it's a 250 you didn't even have that. All the stuff you did added about 10-15 total hp on an IS350.... maybe 8-12 on a 250. And is about all you're gonna get if you want to stay legal. If you don't care about legal the mazzuri headers are a good option. But otherwise the best/cheapest way to make a 250 significantly faster remains to trade it in for a 350, and the best/cheapest way to make a 350 significantly faster is to trade it in for an IS-F.
