[JGE_4G15]

er...all sifus....I'm not trying to ask stupid questions but i'm newbie here....what is NA upgrade?

 

[Fluffy]

naturally aspirated. non-forced induction based engines.


go for intake and exhaust..then maximize flow with port and polish then high cams.
then maybe bore and stroke.

 

[MaNofWaR]

yup...agreed with fluffy
u can start with minor things like air filter, spark plugs, cable plugs, exhaust & throttle body
then probe the internals

 

[simonchangwaimun]

get mivec throttle,bore it larger by 1mm
272 matspeed cams
exhaust,straight flow wan...
open pod filter...
cold air intake...
should be suffice...
bro...with power,u need handling

 

[SkYwAlKeR]

[gtishadowfax]

bro xing honh...the main question is...how much $$$$ are u willing to burrrnnnn???

i guess u have optimised the standard settings...then decide to mod coz of the need of more power.....

 

[gtishadowfax]

oh and one more thing...30% of increase of engine power does not require a mod to the exhaust system...

better balance the engine first la bro...then change the necessary parts, i.e the belts, spark plugs, fuel filter not to mention engine oil, oil filter, clean the air filter, check on engine mountings, steering rack, lower arms, front and rear absorber mounting, absorber link, trailing arm, driveshafts, absorbers, skim the disc brake if necessary, check on the hoses, i.e radiator hoses, brake hoses ( recommend to change to steel braided hoses), brake pads (heavy duty - i.e mintex/metal king will work just fine...) and of course the bushes - make sure they are intact...

then u go dyno...see on standard how many horses are there...and plan, what do u need the modification for - low end pick-up? mid range power? or top end?

the standard setting gives the best balance of all those, whereas, if u modify for pick up, top end is usually sacrificed, vice versa...

then ask yourself about your ability...are u capable to handle the power...standard setting, have u sucessfully optimised it? and are u prepared to handle the extra power from modification?

i wud rather upgrade my ability first, before upgrading the cars performance. spend the money for advance driving, track sessions, etc...find a good sifu...

but, that's just me...........

 

[Prodrive_2068]

N/A upgrade..?? simple..u have lots of things to play around with..from intakes,cams,piping,and such..i was before this running on a N/A built gti..powerful..i changed cams..and bore my inlet as well as exhaust manifold..gave me almost 20% power increment..

but when changing cams..remmeber to have a safc or better still,an e-manage..cause u need to remap ur fueling..pistons nothing much u can do..but u can bore to a bigger size la..put R3 pistons inside..hehhe..with the cams and such..u can tapau an R3 easily..i know i did..

i think thats all i can contribute..quite a newbie in this actually..gud luck and all the best with ur mod..

cheerss..!!!

 

[Y a k u Z a]

excuse me ProDrive broo,as I noticed from the GTi thread,when you were running on N/A you were using the Siemens ECU right? since your car belongs to the `02 batch.

 

[cik_yat]

[dome zero]
