weight between Stock Engine and JDM B16A SIRII

1. Lets say I have a 94 DX, and its engine is D15(rite?), what is the engines weight differences compare to a JDM B16A Sir2 engine?

2. If their weight difference is 100lbs(heavier than stock), then I assume the Tein STech made for stock engine will not hold the B16A, will the springs made for integra DC2/4(94-01) work on the EG HB?

Thanks.

DUDE yes you can use those, Tein is under rates their springs, those can hold up a a h22
