D16y8, d15 faster than my 92 Celica 2.2 5sfe?

My brothers have Hondas and is faster than my 92 Celica 5sfe engine. They have a D15 and a D16y8. Why? Is this rite or is there something wrong with my 5sfe?

The 5sfe has like 135hp and the d15 has like 100hp and the d16y8 has like 130hp, factors come into play like how many miles each motor has on it, if any of the motors have any mods, are all cars manual or automatic, is there 1 auto and 2 manual or 1 manual and 2 auto, the shifting of an automatic and manual happen at different rpms which effects speed, probably the key factor is the driver, if you guys are racing each drivers timing of movements is quicker or slower than the other drivers
