hi all bosses,

i have a 4g13p proton saga engine with 12 valves. All my engine bearings is spoilt. i Would like to change my bearing to racing bearings. I heard that King's bearings are good. Can i use this bearings in my engine. why i am asking to change to racing bearing is because later i want to upgrade to racing cams and pulley. Pls if anyone can help me in the engine bearing cams and modifications and anywhere i can buy this engine parts from.

thanks you

if ure aiming to build an all-out high rpm engine, then upgrading the bearings would be worth it

what cams/specs are u planning to use?

As i heard from my friend, guys from matt speed do a great job on regrind your existing cam n give u the type of profile u wanted . Other than put in racing bearings , u can go for crank n conrod balancing. It will gives u more smoothness n can get xtra few hundred rpm.

yea matspeed cams give a nice fatter mid to top as compared to the pipercams ive owned previously

biggest bang for buck mod is to swap out the block to a 4g15 one

Like this, its abit hard wo unless u're running EFI ......
I heard some dude with 4G13 can outrun other bigger CC car with a webber . But this option is too risky ....
I suggest u stick with cams, flywheel , PNP, adj cam pulley, fine tuned extractor , or if possible rebuild the engine.
I heard nowdays 4G15 doesn't come cheap. Its quite expensive ....

If i'm at ur position lar, i will go for PNP, Extractor , replace bigger carburetor, adjustable cam pulley, performance plugs & plug cable,then if got extra budget i'll go for engine rebuild, rebore, replace piston, bearings ........
