Oversize Everything

[gearspeed]

This is what shops overseas told me and some shops here said to me that if I go higher horsepower on a turbo I should oversize everything.
Is this true that I have to oversize everything on the engine?

Thanks.

syempre coz high boost pressure puts a lot of stress on engine parts

stock N/A engine parts weren't made to handle high boost pressure

you need stronger everything

stronger pistons, stronger crankshaft, stronger connecting rods, stronger cylinder head bolts, etc

Yes I know stock won't handle the stress
I know I have to purchase aftermarket parts but which one is it the high comp pistons or should it be low comp pistons for turbo set up?

Thanks.

high compression pistons for all-motor

low compression pistons for turbo

[gearspeed]

high compression pistons for all-motor

low compression pistons for turbo

Then what they said to me is wrong it shouldn't be oversize everything.

huh?

ano mali doon?

what does that have to do with oversize?

if you're boosting an N/A engine (N/A engines have high compression pistons) you replace the pistons with low compression ones coz it's unsafe to use high compression pistons with high boost pressure (prone to detonation)
