Which parts in 4AGZE are low comp.

[Jusdrifn 86]

Which pistons are you using? 4agze? I thought they were much lower compression for boost... can you explain in a bit more detail which main engine parts you used from which engine, I basically have 2 whole engines to make a monster from, except I cannot use my 4age crankshaft (unless need be and I source a new one)

Hey champ, im using 4agze pistons, I have a complete 4agze bottom end minus the turbo/super charger setup and am running a 1m HG, And a massivlely port and polished bigport head.

now that one engine you want to build is it with or without a supercharger?

[dr1ft-pig]

i think he wants it normally aspirated

[Hen may possibly be a nut]

I'm very surprised it's that high. Has the head been shaved a lot? Or anything else done? And how did you measure the CR?

Hey mate, my head has had alot of work lol.. $1500 in total actually or $2300 including the cams.

my mechanic gave me the readings when he built my motor.

[Sam-Q]

you would need to take off like 2mm off the head to have that comp ratio

[gumbie]

Yeah i im pretty sure it was around 2mm shaved.

[Sam-Q]

well that was a good guess

doesnt make sense to me though, the compression is too high for a supercharger and the pistons are heavier than normal 4age pistons which would of kept the head intact.

If you read up my motor is NA
