i got a crx si a few days ago n have plans on swappin a motor in.. i plan on turboing whtaever it is but i want to keep the price down, so i was thinking homemade turbo on either an z6/y8, d15b (vti), or take the ls outta my hatch n turbo it when i sell it. more likely is the d series. i hear the d15b is better than the z6 and y8...more hp and higher reving? is this true?.... either that or ima get a dohc zc n turbo that...but i only wanna spend around 600 for a motor. also could i attach my SI tranny to the d15b or ex motor????
