I think his 4G15 is fitted with 1.6 pistons...... otherwise 8.5 seconds is really kind of impossible....But I am unsure, coz 4G15 twin weber can kick ass......

i wan say is the most important is the clutch set no much slip so more the power is fully transmit to gear box compare to ori cluth set...then engine running stock is for save fuel so the power not fully utilise.. is depend how we understand the engine and how engine work and how to tweek the engine for performance and how for economical all we need is to undestand so we can tune to better porformance ... yas i admit 4g15 engin cant go much power band but abit sure can...4g15is not a powerful engine but for learning sure is a good basic engine.... chear i still on learning

Dun compare with VIOS la bro....

Vios vs 4g15

1) Dohc vs SOhc
2) 16v vs 12v
3) high compression vs low compression
4) VVt vs apa pun talak tech
5) light weight vs heavy weight
6) 110hp 140Nm vs 80hp 100Nm
=============================

above the list already kill 4g15 stock to stock lo..hahaha

but for my 4g15..consider heavy mod liao did 8.3sec hahaha....only 0-100 other then that...every car can smoke kaw me ..hahahah

that y i say vios is auto me is manual........ the car lost is power at the transmision itself.....soch is mid range power doch is high range power.... vvt is for cam profiling auto adjust for performance at low and high engine speed and fuel economical.... .. and i would like to say vios is low compression than 4g15 is high compression...4g15 ori is 80hp but after twek abit then ok abit lo ... but still kena tapau by many car lo hahahahahaha boring dy ,, plan to get vios....

VIos compression ratio is 10.5:1
4g15 compression ratio only 9.2:1

this is why you see Vios pickup is to light..
