Well im not exactly an expert, but the k20a1 is around 215hp and your car should be pushin 197hp if my memory serves correct. you could get a cheaper turbo kit off ebay but i've seen some that dont do a thing. on the other hand i have seem some decent turbo kits for around 1500-2ooo either way you'll need another 1000 for a tune. i know the swap would be more expensive but thats what i would do plus it would be sweet to have a type-r motor. any way thats what i want to do since i myself have a 2005 si however the k24 is just caught my attention.any way enough about me good luck with your swap or boost either way the o7si is a sick ride 6speed is sick

A K23A1 what is that? To the best of knowledge I don't think that engine exists.

Anyway if you turbo then you are going to run into tuning issues because Hondata does make a k-pro for your engine. also a full greddy kit costs around 3000 just for the kit so figure another 500 for a tune. i would swap your block out for a K24A2 which will give you some low end torque. then get a good header and exhaust and call it a day.

FYI... a K23a1 is from an Acura RDX. Its Acura's SUV and its turbocharged
