mate i honestly think that the money you spend doing a teg type R conversion, you could make a b16a go shit loads faster. With the money you could get overbored dished low compressionpistons which would bring the capicity up to 1800cc neway and conbined with a decompression gasket you could get your compression down to 8:1 or 7:1 as apposed to 10:1. with the compression and some bigger injectors you could easyily get a good turbo setup and run around 15lbs. That would Smoke a B18C5/6
