i had a few questions about a build i am doing, i was wondering if it would be fine to run on pump gas.. i did the online calculator and it came to 13:1.. heres the setup

b16 head - all stock
b18c1 block
LS crank
LS rods
CTR pistons
OEM head gasket
arp head studs

would this setup be ok to run on 93 octane? anything i could do different to have a decent setup? is this setup just retarded?

 

It is not pump gas friendly nor a really good combination for whp production.

Go with either RS machine ITR or P30 pistons.

 

if you want to make 160whp go for it.
get rid of those bigass domed ctr pistons.

 

The cam is going to dictate what compression ratio you can run not the fuel . . .

 

alright thanks for the replies fellas. looks like i will be going with some p30 pistons, since i can get some for 20 bucks right now lol

 

lol CTR pistons.. when will people learn.. that piston is a PCT, **** Crap Trash.

 

Whats wrong with the ctr's?

 

alot..

For starters they came in a b16 block, if they are used, they shoudl only be used, in a b16 block

They're very heavy..
They distort the flame combustion process
They have too much of an angle on the dome


They are just **** pistons..
Putting these pistons in anything but a b16 block.. will have your CR through the root.
deck height, rod length, crank , all these play a role in CR and these pistons.. put you at high 13's in a gsr or ls block.. no matter what combo you use.
