Hi , I had some noob question to ask , I had a injection 4g91 in my iswara , I wish to know what upgrade can be done to let it to be more powerful and fast .

I want the best upgrade to be done which does not always cause problem had to repair .

Can all sifu sifu teach how to mod ? mod by step by step like change which part then next stage change which part again ? And if change which part had to change together only will do .

Please list down the modification with the COST also .. tq very much .Cost is not a problem , just wish to know .

Small cost of modification and cause more power will be nice .

My target is just want upgrade the power until like 1.6 or 1.8 , is enough . 2.0 upgrade stuff not recommend . And I want to know what is a oil catch tank , what the function for ?



Can what I list down can be fit in a 4g 91 . Will it suit ? Any side effect , does it run smooth and in good condition .will in be too much for a 4g91 ?


4g92 1.8 / 1.6 cam ?
Wat different between a high cam , and plus together with the adjustable cam pulley .

240cc injectors

4g93/92 exhaust manifold & wesgate

4g93/92 intake manifold

4g93/92 engine head

4g93/92 piston ( had to bored the block to be bigger ? ) Any side effect ?

4G93/92 Throttle body

# Any other pls teach , I just know abit only . sorry for so much question .

guess u need to drop by 4G91 thread la.....
n also...
from wat u posted on ur list....
very obvious dat u dun know wat to do la.....

ur engine is a n/a...
so wastegate is totally an alien la.....

as for the intake manifold...
a lot of 91 users says dat using GSR intake manifold is the best...
short n bigger holes.....
paired wif evo/mivec 60mm throttle body......
u can port n polish ur engine head also....

as for the cams....
4g93 cams r slightly higher....
but then far away from highcams la....
the adjustable cam pulley can let u set ur cam for better power....
depending on ur requirements la (mid/high?)

as for exhaust....
get a better flow one la...
4-2-1 of any brands....
or even get stock 4g93 exhaust manifold which is ori 4-2-1....
then piping change slightly bigger ones lo.....

as for pistons n engine blocks....
u can either change 92 or 93 block or change oversize pistons.....
then fuel regulator la...
piggyback or standalone la....

anyway...
since u say money is not a prob...
y not just go to a mechanic n tell him u wan power....
let him do watever he do...
then just pay the money n drive off lo....

Ic, tq .
Gsr is 4g93 right ? wat the different between 4g93 things and 4g18 ? izit the same ?
Izit 1 sohc, another is dohc ?

Changing gsr intake manifold and bigger throttle body mean will let more air go in , those it mean need to change the injector bigger abit to let it balance ??? since more air go in and the fuel inject still same . And changing bigger intake manifold and bigger throttle body plus if I change the injector too , should I also change bigger exhaust manifold together to balance the air ??

What is mean by port n polish engine head ? bore them bigger ?

4g93 cam need modified to fit in 4g91 or not ?

What is the high cam side effect since u all told me not to install .

If I did not change to other cam , can I still install adjustable cam pulley ???

4g92 / 93 block fit 4g91 ?? change over size piston need to bore the block ah ???

what is mean by piggyback or standalone ???

Money matter is can be discuss and consider , I not very poor n not very rich , just middle, if I just go to the mechanic and ask him install everythings then pay is no meaning , learn nothing , better I go buy a new power car . just want to know what those thngs function . Sorry for asking back all your question because I just learn , still a noob . Everythngs start from zero . Hope you all teach me .

- port ur head. (rm 300 to rm 700)

- mivec exhaust manifold. (rm 250 to rm 350) if you are lucky enuf to find one.

- gsr intake manifold. (rm 250 - rm 350)
