to swap or not to swap.?

[rob22]

so i have a built ka sitting in my garage.
its for a ka-t set up

motor has the following done to it:
stage 2 jwt cams
cosmetic metal head gasket
brand new oem valve train
arp head studs
arias low comp pistons
molley rings
magnafluxed,lightened and rebalanced
all new oem bearings
head resurfaced
yada yada yada....

my question is would it be bad to run the motor without a turbo set up.?
what problems would i run into.?

discuss...

arias low compression pistons.

N/A motors use higher comp
boosted motors use lower compression

Your motor could make far less power than a stock KA

that depends on the compression ratio it has if it's 9:1 you wont hate your self too much if it's 8.5:1 you will definitely hate yourself
