1- Civic Si in canada have supposely a speed limiter at about 212km/h. Does the reflash disable this???

2- Oil pump on K20Z3 is balanced for smooth operation but sucks about 3 or 4 hp. Does the K20A2 or K20Z1 oil pump would fit on my k20z3?

1- Yes, but you'll need to get the ECU part number first to make sure that the reflash will work. It starts with 37820-R

2 - It depends if the K20Z3 has the stepped girdle below the main bearing cap like the K24. If not, the K20A2 oil pumps bolts straight on, if so, then the oil pump needs to be machined for clearance.

How many hp you think it would give?? (about answer #2)

From memory the figures from Honda with the K20Z3 engine vs the K20Z1 engine were +7 hp from electric power steering and -10 hp from the egg beaters. A fair guess would be 5-10 hp.
