I have a sand car with a 02 honda odyssey 3.5L,      T4 single turbo 9LBS boost and the ecu is from
a 99 acura tl 3.2L the car is real fast
but would love more power any ideas. ALl my friends drive v8 cars.  

My friend... 1st, it's a minivan. 2nd, do what floats your boat. I like cars with V8s as much as the next guy but it doesn't mean that you should give into those dopes that are most likely bothering you about it. That's what it sounds like to me, at least.
I have a vision of taking the V6 out of the Sienna that I own and install a Supra engine. Or, maybe see how compatible the two are and do some serious upgrading. Do you see where I'm heading with what I'm saying? I do what will float my boat, no matter what people may think. That's why it's called tuning. No limits, holmes, no limits.
