Sifu catacombs sudah spoken
btw, plonking in a 4G6series engine won't affect ur engine mounting. But jumping from 1300cc to 2000cc displacement is impossible unless u "ahem" those officers with $$$

Best to get the 4G61T engine.
Since urs 1.3L y dun u straight go for 4G92DOHC/P terus??? Maxed out the displacement limit. Make sure the crossmember front and rear mounting are properly measured, aligned and welded. Same goes with ur timing belt side mounting. Custom made mounting with proper welding not "taik kambing" welding
As for the UR add-on stabilizer bars, try completing the whole set thats available like:
Front Upper Struts 3point
Front Lower Arm 2point
Fender Bars 3point
Side Bars 4point
Mid Lower Arm 4point
Rear ARB 19mm
Room Bar 2point
Rear Struts 3point
Rear Upper Bar 2point
Wat else did I missed out??? anyway, if u r still not satisfy enuf with the handling/stabilities after adding all those bars above, time to rollcage the whole car la
About the turbocharging chapter, no comment. I m still noob in turbos

it is hard to find 4g92 mivec manual transmission as i m in sarawak... what do u mean by "aligned and welded"??? if i change to 4g92 i need to relocate all the engine mounting??? if lik tat still can pass the puspakom endorsement??? (i need my car to be street legal)
and for all the ultra racing bars my friend who own a workshop says not all the bars is important as i m not going to for rally... he says only some of the important bar i can put onto my car
1. front upper strut bar...mayb change to apexi (if not mistaken is this brand) 4 point
2.front anti roll bar
3.rear anti roll bar
4.room bar
5.rear strut bar
6.rear upper bar
i dont know actually how many bars left but if if my budget is enof then i will put on all...

yes, u can plonk in a turbocharger or supercharger into ur 4g91 with low boost pressure... yes it will increase horsepower by forcing more air into the engine... i dont know whats ur definition of "modifying the engine"... so, no comment on that...
when u change to 4g91, u are changing the block already... yes u can rebore the block to fit bigger piston... but it is not recommended if u going forced induction... and if u planning to go for forced induction, i suggest u to get 4g92 block with 4agze piston... those piston are semi-forged (if not mistaken)... get thicker metal head gasket for low compression purpose... u can start off with td04 turbine... relatively cheap to start with... as usual, u need other components as well if u going for turbocharging... as for supercharger, i'm not very familiar with it though...
temporary u dont need to modify ur gearbox... maintain standard ratio good enough d... use better clutch or racing clutch if budget permits...
yes u can use aftermarket slotted/cross drilled rotors... make sure its compatible with vr4 oem rotors, if u are planning to install vr4 complete brake set to ur car...
of coz u can stick back to 16"... u can use any size of rim as long as it clears ur uprated brake set... dont forget to use good rubbers... bad quality wide tyres arent necessary better than good quality less wide ones.... yes, smaller/lighter wheels gives better acceleration...
many more stabilizer bars available for saga iswara... try browse thru ultraracing website for complete list... adding 1 bar aint gonne give huge improvement.... as in bars, the more the better...
yes u need to change the whole exhaust system as well... 4g13 extractor will not fit 4g91... it is 2 different type of engine... as for piping setup, presumably u are going forced induction, a larger piping is needed... we will touch on this once u finalize what u are going to do with ur engine...
ps: macha, dun multipost laa...
thank you sifu...
for what i mean is a 4g91 original with bot... not modifying the 4g91 enigne (all the interior parts stick back to original 4g91 parts)...
as i know it is illegal if i use 4g91 with 4g63 block, rite??? the engine number is stamped on the block... if i past endorsement with 4g91 and change the block then count as illegal too...
for the tyres can give suggestion on good tyre??? now my car is using two continental sportcontact 1 205/45/r16 for the wheels infront (coz at the shop tat times got only 3 tyres that i cant change all 4) and two cheap indonesia corsa 205/45/r16 tyres at the back...
