so i want to turbo my civic, but i can't do it legally since my converter and header is one peice. if i bought a EX Catylic Converter and turbo kit, would this be carb legal?

 

O dear lord jesus christ, please go do more research. And if you buy a Greddy kit, I think they are all carb legal. Also when you turbo your car you lose the stock header...

 

there is no carb legal turbo kit for the d17.. sorry.. move to a state that doesn't have socialists running it

 

well there ya go lol, or you could just pay off the smog people.

 

well on the EX, the cat is on the exhaust pipe. can't i just cut the downpipe so it cuts off right before the catylic...?

 

i'm assuming you live in CA where carb legal matters. I guess you 'could' do that, but the stock cat is only like 1.5" or something. way too restrictive for a turbo. you can get a highflow cat, but i dont know how much success they have with smog testing. if you are worried at all, turbo is probably not a good plan. i would look into a swap if you're worried about emissions.

 

what kind of motor swap do you think?

b16 or k20?

 

you cant swap a b into a 7th gen. here's where you start searching. any k-series is pretty straight forward, there is even a comprehensive diy made by xproductionz. it is not legal to do a b swap into a 7th gen, or practical, and cost prohibitive.

 

hmm!! i should get a K23 motor, that'll solve my turbo/carb problem! haha, how much does a used k23 motor cost?

 

look he has been really nice about helping you, DO RESEARCH OMG!!!! were not going to tell you how to do everything.
