Can be done. 1.6 clutch is heavier if compared to 1.3 clutch, so the flywheel need to be lightened (skimmed) to make it equal to the weight of 1.3 clutch + flywheel (before skimming).

my advice, jz gt a 4g15 block and stroke it to 1.6. Mild mod will improve the torque slightly only.

Auto or Manual? The TB is a 1.5 VDO TB or the 1.8 VDO TB? What's the condition of your spark plug cables? What engine oil weight are you using?

Hi Guys,

I haven't been here for a while now... for those who did follow my 1st Gen Saga mods, FYI (car is currently under going recovery from an apartment fire).

So 1st up, since I am doing "Project Saga 2 (the recovery)" I need help and advise from some sifu's here about the following...

This is my current car specs that are not standard:
- Naturally Aspired 1.5 (12 valves, Carb, Manual)
- Hotbits Extractor with 1.75" Exhaust.
- Alloy Crank Pulley
- Bosch Super 4 Spark Plugs
- NGK Plug Cable
- ICEEEEE :proud:
- After market steering wheel with boss kit.
- 15" JRD Alloy Rims
- Strut Bar
- Short Shifter
- K&N 3" Open pod air filter
- Razo NA/Turbo Timer
- Swoosh Vacuum & Volt meter
- Zaptor voltage regulator and DIY grounding cables.

I am planning to do the following upgrades, any advise, comments or suggestions?

1. "Sparco" Steering Quick Release (anyone using? does it shake?)

2. "SARD" Fuel pressure regulator (I am using the standard saga carb, is this upgrade ok? or do I need to change the fuel rail and weber carb also before doing this upgrade?)

3. Arospeed Cam Pulley (or should I use the standard one since I am not going to put in Hi Cam?)

4. Mod 1.6 flywheel? (got benefit or the increase in power is not worth the cost & time?)

5. Exedy semi racing clutch? (or should I just stick to standard? benefits?)

Thanks in advance to those who reply. Appreciate it.

Just got a 4g91 fuel injection Auto half cut, planning to install it into my old wira and replace the original 4g15 carb 1.5 auto which has terrible FC. Starts blowing out white smoke once i drive up to 80kmph.
Question is will i get more power in terms of pick up or mid from this 4G91 auto? Will the FC improve as well? This half cut mileage is already 160,000km by the way.
What do i need to change once this engine has been transplanted?
Many thanks.

bro sure the FC will become better

but since ur halfcut already 160K KM is better to change all tear and wear part togather as well as timing belt set together

1.engine oil (is better to get semi or fully oil - will improve FC also)
2.gear oil (change oil first if got problem u neeed to take out the whole gearbox to gearbox specialist to service)
3.brake oil (i think the forman sure will change for u)
4. aircond gas and oil (I think the forman will change for u also - since half cut come in already cut the pipe)
5.power steering oil (i think the forman sure will change for u)
6.timing belt, oil seal water pump, air cond belt, power steering belt

i think u done the above is good enough already

More than likely located stock position which is under the signal lamps on the side. People relocate them to the front for ease of installation.

You should try changing the plug cables. I don't know how your mech checked the cables. This kind of power loss is usually electrically related.
