Proton Saga FLX Campro 1.3 to 1.6 conversion

Proton Campro 1.3 convert to 1.6

Do you own a 1.3-Litre Campro Proton Saga FLX, Saga BLM, Saga FL, or Satria Neo? You can actually convert the 1300CC Campro engine to 1600CC Campro and get an extra 300cc! What does this extra 300cc of Campro power bring you? Well for starters, with the Campro 1.3 convert to 1.6, you will get about 14 extra horsepower and 30Nm of torque. No replacement for displacement! Essentially other parts are the same, the injectors and throttle body are also the same.

So what would you need to stroke the 1.3 Campro to 1.6? The stroker kit would consist of: Campro 1.6 crankshaft, Campro 1.6 conrods and pistons. All these can be bought easily on Mudah.my and sells for below RM2,000. Along with the main Campro 1.6-Litre stroker parts, you would need new engine bearings and piston rings, which would cost a few hundred. The whole 1.3-Litre to 1.6-Litre Campro conversion costs RM2,500-3,000 inclusive of labour. Was it worth it? Totally!

Note: The 1.6-Litre Campro pistons and 1.3-Litre pistons have a different head design, with the 1600cc giving a lower compression while the 1.3-Litre has a higher compression. The conrod lengths are also different.

2012 Proton Saga FLX bolt on turbo

Running on a Subaru TD04. Fueling is helped a little with Works Fuel Pressure Regulator

Here is my own 2012 Proton Saga FLX bolt on turbo. Currently running without management, still able to boost up to 0.4 bar (albeit with bad fuel consumption). Saving up for a Haltech Sprint 500 standalone! To complement the power, a new semi-racing clutch will be dropped in. Next is to upgrade the brake system to a double servo pump, and better brake pads. The car is currently running on a lowered spring setup (Sapura sports spring) which is sufficient for daily usage. Overall quite satisfied with this bolt on turbo Saga FLX setup, as the sound emitted is not too loud, and sounds like a standard ride. Even my intercooler is well hidden inside, as I intend to achieve a sleeper look.

Proton Saga FLX bolt on turbo with subtle intercooler. Looks stock! 

Final objective will be to stroke it to 1600cc with new crankshaft, forged conrods and forged pistons; aiming at about 200whp! For a little car like this it is more than enough.

Enjoy the pictures. Any question feel free to comment!

Some FAQ I got from fellow Campro mod enthusiasts:

1) Can the Campro engine cope without management?
Not advisable  but as long as you don't boost recklessly you can drive it fine with occasional boost (not more than 0.4-0.5 bar, according to several tuners).  The car runs fine, nearly 2 months and counting. No problems encountered so far, except that my stock clutch is already slipping :)

2) Why don't you install management?
Campro's ECU runs on a closed loop system, so it will override piggy-back management such as E-manage (some had success with Works EMS-1 though). I plan to just use a standalone like Haltech Sprint 500. This Haltech Sprint 500 standalone ECU cost about RM4,000-5,000 with installation, tuning, and dyno. Planning to drop in the internals together.

3) What is the estimated horsepower without management?
I'm not going to lie and tell you fancy stories, since mine is only 1.3-litre my butt dyno tells me the car's current whp is about 90whp, albeit wtih much more torque.

4) Are forged internals even available for the Campro? How much?
Yes they are, CP forged pistons go for about RM2k+, and custom made forged conrods about RM1k+.

5) After bolt on turbo what is your top speed?
Unfortunately bolt on turbo doesn't modify my gear ratio. My current top speed on this Saga FLX is about 190km/h.

6) What is your fuel consumption without management?
When it was stock my FC was 10-11km/L (abysmal figure). After bolt on turbo, FC stands at about 8-10km/L (depending on how much I boost).

7) How much did you spend for this bolt on turbo project?
About RM2,800, without labour.
