i found out hmotorsonline.com has it for even less. like $835 shipped.
d15 because they are cheap, and i can find them easily. i could afford a b-series swap, but only the swap. with the d15, i can afford to put rods and pistons in, and boost a little higher, knowing the rods will hold. i would just boost the d15b7 i have in my car, but the rods are small, and i dont have another car to drive meanwhile....so ill work on the engine, buy all the turbo stuff, and spend several long hard days putting it all in.
