welcome man!!!
well dsm's are really cool cars, fun to drive and powerfull, but all that comes with a price
if u want to start modifyng it u should set your goals so u dont spend your money on stuff u would regret later!!! one thing is for sure this cars comes with a lot of electrical problems so far i had replace the MAF sensor twice, idle control valve, cluster gauges, transmission computer and solenoid pack, egr solenoid, evap solenoid and nothing is cheap all their parts are expensive but u have a very strong engine!!! so strong that i ran mine with no oil and water pump for a couple of hours and survived (not recomended) so good luck with your project another advise dont cut corners on maintance and parts cus they will hunt you!!! good luck again and welcome
