Any workshop have good review of bolt on turbo?

Planning to bolt on turbo my manual Preve, looking for workshop around Petaling Jaya, Subang, Shah Alam, Puchong, Putrajaya is recommended, by as long as within Klang Valley also can la.

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.

I'm curious, is engine swap is still legal? Sometime ago engine swap is restricted because it's considered modification.

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.

• Krypto Motorsports
• Tam Turbo Motorsports
• Marmad Auto Performance
• Gearboss Performance

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

I'm looking forward for the bolt-on turbo as well for R20 motor. It is believe that the R20 motor stock internal is quite hard already for low to mid boost. I'm looking for 250 BHP/25 KG torque

Well, for the engine alone is at least 5k and above. Easily reach RM10k++ including labour and other parts like gearbox, ECU those.

BOT is more budget for me, I just want small boost, not want to boost 2bar like that lol

I bolt on turbo not for racing la, just want to have more power when the road is steep, and when I want to accelerate.

maybe .5 bar or .7 bar boost like that, not going for 1.5 bar or 2 bar boost lol

Thank you all, I will contact them and see.

Why not? The legal way is to write a letter to JPJ for modification approval with the engine information or custom form (If buy from half-cut shop). If swap from another car take the car geran information. Normally a 20% allowance for cc increase from original size. The most important is not to alter, cut or weld the main chassis, the rest can be kautim.

It’s 25% now. Used to be 30%

FYI, original stock 1.8 GSR turbo boost is around 0.6~0.8 bar. Those 2 bar is already modify kau kau.
Just google about bolt on turbo on proton engine from local magazine. Most of it in the end also over 10k and a lot of trial and error which will cause a lot of time & headache. After you done your modification, you will get another part worried is the parts you modify into your car mostly are customize and normal mechanic wont dare to take risk if anything serious and you will have to go back to the mechanic that help you to modify.

Turbocharging is never cheap, not even BOT.

Turbocharger
Wastegate
BOV
Exhaust manifold
Intake
Intercooler and piping
Intake system
Oil coolant lines
Piggyback ECU

Of course you can have a budget BOT, but most likely your car will be staying in the workshop more than driving it on the road.

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.

for proton only perdana and inspira allow 2.0. other limited to 1836 cc. other model wont pass puspakom inspection/endorse.

legal but there's TnC stated at jpj website.

BOT im not sure u need to endorse it. engine number is the same if you're using the same block.

i've change my proton engine and mod it etc.

word of advice, do it right first time and endorse it (insurance wont layan your claim if geran details is differ than whats under the hood).

proper mod + original stuff = reliability. Dont take short cut.

for what i have read, G tuned racing has been doing CVT tuning for the preve starting last year. so it is okay to modify the turbo (within limit) to the cvt. can try first

Don't forget injectors and fuel pump, also boost controller and some gauges like boost meter, and AF meter at the very least.
