one thing to clear it off, the engine maned as CAMPRO is because the cam profile they used is different from the normal engine (and i don't mean performance engine over here).
The engine did some very impressive figure on prototype GEN2, which is 165BHP stock and without CPS. but same as the production, the engine do equipped with VIM system. and thisfigure achieved without violating Euro 4 emmission standard.
but due to the cost problem (plotong alwaysliked to cut cost for profit...) the engine used some rather cheaper material and the horsepower is reduced to the figure shown today......
and to fully boost the ability of the campro, you need some very skilled engineer to tune the ECU up. which none exist in any Klang valley service centers.... but there's one at batu pahat.
for my Gen2, i can have my 0 to 100 kph with near to 9 sec. and this is achieved without the need to fully depress the acceletor.
CAMPRO is a good anddecent engine. for mine, the torque is maintained from range of 2000rpm to 5500rpm. I don't think any of the "normal" japanese car seen in malaysian market have the same capability.
This statement is valid for my 2005 DEC Lennox black HL manual GEN2. i do not sure the previous batch, but I have a friend with 1st batch GEN2 mentioned the same thing.
You mena torque is maintained from 2000 to 6500 rpm.
