why not just get a JDM B16a2...its got 170 hp...10 less than the B18c1...and much less cost...you can rev it higher...and the grand you save on the engine you can more than make up the 10hp for...and you can get an LSD for it with the engine depending on what engine place you go through...i have nothing against the B18c1 engine...but for the price..you CANT beat the b16a2 or any second gen b16a
