Best way to improve performance is to have a lot of money.

[azharzawawi]

1st stage - pnp head, camshaft and adjustable cam pulley... any aftermarket brand will do, alloy crankpulley any brand, extractor, 8" flywheel + clutch n clutch cover.

2nd stage - 4g15 block and internal, Fuel Injection set, upgraded front disk brake, rear disk brake, double layer servo.

3rd stage - 4g18/s4ph crank, oversize piston, engine management/piggyback etc, steel braided brake hose, Alloy radiator + fan + fan shroud.

4g15 can use 4g18 crank???...

Probably not. But what most people do is use the campro one. *ahem cough secret cough ahem*

4G13 mods, best bang for buck is to better jump to 4G15 block and start from there~~

If want to maintain 1.3L and see how far it can go, saw a lot of 4G13 dynoed around 75whp to 80whp range NA :)

Price depends on your luck on getting a cheap and cheerful block.

Legal procedure : do your swap, go Puspakom for inspection, go JPJ to update car registration card with new block number.

Illegal procedure : do your swap, keep quiet, don't get into accident.

Oh ya.. when buying the block make sure it comes with the grant. If not you will have a hard time registering it.

 

[azharzawawi]

luck....normally 1.5 block and internal price around?

hehe..btw..thanks for giving me all the info...:wavey:

as i done my research on it earlier, its very hard to get only the block, even if they have it without the grant. "Engine kosong" probably will cost around 1.2k (block + head)...

This is what I have done to my 4g13... Done it when fully rebuilt my engine
-Over-sized pistons (74mm)
-Bigger clutch (1.6)
-Bigger bearings
-1.6 throttle body
-exhaust system (4-2-1, mid bullet, s-flow(gti style)

2nd gear can reach 70km/h at 5krpm
3rd gear 110km/h plus...

hope this info helps you bro... :)
