Bro, is better to find a 1.8T GSR turbo half-cut and transplant.. A lot of those bolt on turbo require a lot of side modification like upgrading the radiator, thicker gasket, oil cooler add on, ECU remap/upgrade etc will add up a lot of cost and in the end is better to get a half-cut.. Less headache for the driver & mechanic..

Campro engine? Waste of time and resource imho. Might as well go for 4g63t or 4g93t. Since it’s 1.6, you can drop in up to 2.0 engine and get it endorsed without any issue.

An engine swap is better than BOT in the long run and you’ll be having less headache if turbo is an alien to you.

How serious are you ? are you going to high boost?

If you want to do things properly, then your conrod bearing, head gasket, fuel injector, fuel pump, ecu etc all have to upgrade. Not to forget the braking system as well.

Those after market addon turbo kit usually is just some low boost turbo.

Not in order of the best or whatever.

For me, just bolt on turbo.  Don't listen to those naysayers.
Understand the limitations and restriction, set a plausible power goals within the limitation or restriction.

how about using sprintex supercharger ? try asking G Tuned Racing PJ

You try google pak tam turbo / tam turbo motorsport
He is very well known with turbo modification and repair especially for proton cars. He fixes a lot preve/exora bold turbo

His own ride is exora with evo engine. Workshop at kampung melayu subang

Try visit him and hear his opinion...bolt on turbo vs transplant 4g93t

Actually what's wrong with Proton'S CFE engine.
Im not talking about trying to BOT the IAFM engine.
Proton lowered the stock boost just to protect the CVT. Not the engine.

Sadly nobody even tries to replace the gearbox to a stronger non-CVT gearbox followed by replacing the Stock turbocharger and crank up the boost.

All blame the engine just because of the CVT.
All blame the engine just because it wears a Proton badge.
All want to just swap the entire engine to something more glamourest. Evo engine.

I bet if someone dare to up the boost, Honda turbo can kiss its ass goodbye. 205nm vs Honda's 220Nm is not far off. 138hp on CFE vs 173 hp on a Civic turbo. 35 horses difference for a turbo is not a big gap.
Doable with some tuning upgrade (and yes.. add an external oil cooler)

Proton has tried racing with a CFE engine minus the turbo and pumps out 190 horses. NA. Imagine with turbo.

Again nobody tried. Because they lack the confidence. Sadly.
