i have a 2.9 intense pulley on my car with the ecu tune and 42s. no cooling mods as of yet.

first question. if i put the 2.8 on and leave my 42s in and run cooling mods will i be alrite? i keep hearin thats my 42s r maxed out but dont really know.

quetion 2. if i put the 2.8 on and change to 60 injecters do i need a retune at first or can i just bolt them in and drive with out any cels r problems

either way im buyin a heat exchanger and 60s but just wondering..

 

1. 42's wont support a 2.8
2. if you go 60's you need a retune

 

ok thanks..
