What mods do I need to do to get around 450hp and still be able to pull a trailer. Motor does not have a turbo and not wanting to spend over 1000 dollars on just turbo. Any help would be appreciated

 

What happened to the turbo on your 12valve?
As for wanting to get to 450hp, you would have to spend a bit for the 450hp.and you will need the turbo.

 

your in the wrong game to not wanna spend 1000 on a turbo. a box borg warner with out a wastegate is less than a grand but then you must know what your doing tuning wise and how to pick the correct ar turbine housing. as for 450, basically tuning, a 3 or 4 gsk, and a turbo, you may need injectors or dvs. but 450 should be doable on mostly stock fuel parts.
