i promise you will be burning through ANY plugs you buy while you are still tuning your car. run the coppers till everything is stabilized, then get some denso iridiums and be happy.

what kind of turbos are you using?

edit, start with a 6 heat range and go 7 if you are making over 400 hp at the crank.

Thanks for the help.
I cannot use DOHC plugs beceause the SOHC plugs are a different thread pitch and I believe they are a different style all together. I am using a single 20g with a 10cm monster turbine housing. I was going to use coppers to tune with and after I get things stabilized switch to an iridium/ platinum plug. I was just confused as to what heat range would be a good starting point.

Thanx again for the reply.
