Can I fit/ retro fit a digilat speedometer for my 09 civic and put it in another car?

Alright, i'm in the process of attemting to build a prototype style car from a chassis and engine from an older (04)bmw. I currently daily drive a newer honda civic and like the set up and would like to incorporate it into my design. Hopefully i can wire it in with minimal problems i'm not committed to an engine but i must be able to make it rwd. Would like a stronger power plant v6 have thought of using a k20 honda engine but, am unsure if it will wire in all imput helps thank you very much

You can pretty much do whatever you want with a car as long as you have the time and money.

I'm not sure how I would help with the speedo situation but I can the power plant ideas. If you're like me and like the k20 or k series engines, I have found quite a bit of parts and info on k20 engine, s2000 RWD trans adapters and wiring for a kseries it really isn't that hard. I have been wanting to do a large tube car for drag and your project sounds close to what I'm wanting to do as well.

This info may help. You may have to go with a race pak for your gauges though man.
