Im planning on going from stillen stg4 to turbonetics single. The VQ is holding up beautifully at 64,000 mi with stock internals. The question is, since i have i would say higher mileage now, should i just build my bottom end first and then swap it or should i just swap it? Hmmm....

 

too much that we dont know. what/who is tuning, how much power are you looking for, or even moreso how much torque are you wanting to make? how have you been on maintence? any blow by yet from the stillen?

 

IM just hoping to get what the turbonetics tuner kit gives. What is it a little bit above 400hp? Im not wanting to exceed more than what the kit gives. But im just concerned wit the mileage that i have. All maintenance has been done accordingly and appropiately. I'm thinking about going to GTmotorsports out here in s.cali. So far they have a great reputation. I dont know what you mean by blow by with my stillen kit. But to be safe i was wondering if maybe i should build my bottom end?
