our fit has been always been feeling draggy and reluctant to climb slopes ever since the key had been handed to us. not to mention that it seems to take sometime from 0 – 60.

been reading a lot about the car’s poor low end performance and there was nothing much that can be done to improve the situation except to get a larger-capacity engine. after all, it’s just a 1.3 and what more can we expect? nevertheless, some owners suggested to change cold air intake, add grounding and what not.

not familiar with these kinda thing, i began to read more and came across throttle bodies. this particular guy have his own garage right at his car porch and its somewhat his “freelance” business; he offered machine bored throttle bodies for various car models and makes. he claims to have installed over 500+ throttle bodies and mostly were jazz/fit cars. with added testimonials from many people in the forums, it’s not difficult to be tempted to give it a try.

so last friday, we went to this guy’s home-garage and very quickly, he (eddie) took out the battery, opened the air filter box and changed it to a washable type for me and took out the current throttle body. he placed it on the floor next to the new throttle body and immediately i noticed the slightly larger diameter with a new butterfly-plate. cool.

he plugged it in and proceeded with explaining a lot on the throttle body and the new air filter. seeing it was time to do the e.o. servicing, i let him do it for me as well. he saw how dirty the engine bay is and proceeded with clean it for me f.o.c.

he turned on the engine and let the ecu relearn the new throttle body as well as the new e.o. after everything is sort of done, he drove us around in our car to demo to us on how we can gain more boost on a cvt. just barely out of his house, i can already feel the car having more power. shiok.

he told me that it’s our turn to go for a spin with the new mod while he stayed to clean hsi garage. we then drove to the nearby kranji mrt to withdraw some money. the car was practically cruising most of the time without the need to keep on stepping on the accelerator!

when we returned to pay him, we asked a few more stuffs on coilovers and brakes. he literally invited us to sit in his car, a jazz GD fully modded inside out and roaring to go. he was using hks coilovers which costs around $3k+ for a set and the settings was tuned for track racing. on the normal roads. i could feel most of the humps and bumps but the stability is definitely there. his car barely rolled while he did a quick corner on a tight road. totally awesome! i’ve always wanted to “audition” on some of the modified jazz/fits that surfaced in the local fjc forums. though his car was a bit extreme for me, i just wanted find out how hard was it on coilovers.

over the weekend, i had the opportunity to drive on the north-south highway in jb. indeed, getting to 0-100 now is definitely easier than before, plus this time we can freely depress and let it cruise when we reached our desired speed.

this is definitely a worthy investment for me as i only wanted improve the car’s performance without hurting the wallet.
