Hello, I am a new owner of 99 honda prelude 133hp. I am thinking of swaping the engine for H22A Vtec. 1 question is do I need to do some work on the computer cause for the variable valves cause the stock engine is without one. 2 question, my car has LPG installed and i want to keep it, can the mechanic just re-install the lpg into the new engine or do i need a new one. 3 question, do i need a new transaxle, can my stock transmission take the load of the new engine which is like 80 more hp. 4 question. Also anyone that has done this swap, any tips and tricks, Anything I need to know? Thank you in advance.
