u r innocent(tak salah), as long as u didn't get caught, & even u get caught, u still innocent. even, u been sue to court, u still remain innocent b4 the judge place his final words...
this one cannot make it la... LOL... its the most expensive solution i've ever read shiro LOL :proud:
the poor guy just wants low end torque, i believe converting to manual would be more than sufficient liao.. LOL... 3.7 litre engine... OVERKILL !
hehe... but i agreed that statement wor... hehehe.//this one cannot make it la... LOL... its the most expensive solution i've ever read shiro LOL :proud:

not expensive if compare with plonk a Mugen V8 engine...
money matters... i can see Audi R8, Ferrari, F1, WRC, DTM... all auto wat... eehehhe////
new 1 rm1480, used 1 rm880...:proud:
atleast can gain 3-5 whp/ 0.8-1.3kgm of toq. dyno proven at Amoil.:proud:
Ohh ok thanks for the info jin, anyway today i just found out my car vtec open at 5000rpm. I just bought this car half a year ago and never mod the ecu. The past owner is an uncle and never mod anything too. This car is recond year 2001 from japan and only modded with fgk sflow muffler and hks adjustable when arrive here. Does this mean my car have rechip ecu?

i thought auto b16a opens the vtec at 5200? hmmm maybe i was wrong oh well. its hard to tell if ur ecu is rechipped or not... just show JIN ur ecu.. he will know! 
But how come mine vtec engage at 5000rpm? So far havent mod the ecu and notchet install my vafc. But i remember when i just bought the car got ' feel's ' sticker but i took it off. Maybe the past owner in japan mod it :hmmmm:

Actually the 3.7 litre is a joke. Now that is extreme low end power.. ha ha.
I still say some light tune with VAFC will do the trick, because the fuel will be rich at lower end (less power) after he changed to bigger piping.
Cams and others can wait, but since he has already, can put in, although in my experience, it never made much difference. low end is still the same, only the vtec part has better power, and even that with VAFC only.. and not much better too.
The car I was referring to used to be my friends (sold off already) and he went for VAFC tune.
EK B16a with VAFC only managed to get 3hp only at 7800rpm (but this is not where the low end power is!) seems lame, isn't it? and that's because most people only see the higher end of the dyno chart and don't care about the low end.
But from 3-5000rpm, can roughtly get about 2-10hp higher than the stock one. and decreasing as it goes up into the higher rpm ranges.
1-3K rpm usually cannot measure on the dyno.
1000-3500rpm hp and torque increase is what you want if you want low end power.
If you change to bigger cams, the only power increase you'll see in after vtec, and that too, is with proper fuelling.
