My wife and I want to build her daily TL. We are trying to get to or as close as we can to 400hp at the wheels.
the engine was rebuild by Acura of Bellevue 1200 miles ago. So it has new pistons assembly timing belt water pump tensioner. In the heads it has new camshafts.
so far we have installed Takada intake, RV6 JPIPE AND PCD. We have ordered ktuner and it's coming in 2 weeks.
What other bolt on can we do ?
Under Drive crank pulley?? Light weight
i have read using MDX intake plenum and pnp you get good result

 

You are asking for an additional 95hp NA? That is going to be a challenge. That is 30% more output. Don't think you will get there without high compression pistons and monster cams and spinning it to the moon.

Your best bet is going to be forced induction. Easy 500hp and you don't have to open up the engine. Transmission might not like that level of torque.

 

That's why I'm asking
I need to do all this research. Is or possible. ?? If yes what do I need .

 

Deep pockets

 

With goals like that shoulda had the engine rebuilt by 4P rather than Honda.

 

You won't be able to raise the revs with the automatic. The shift point won't be adjustable.

Spinning the engine faster to make HP won't be an option. So now you are looking for more torque at the same RPM. Which is good, a heavy vehicle like a TL needs the mid range torque or it will still feel slow.

Your best option price and goals wise is going to be forced induction. But now you have to balance low RPM big torque with transmission reliability. You might be able to do some boost curve manipulation to do something like make a flat 400ft/lbs from say 2000 to 6500. That is going to feel crazy fast and because you are limiting the torque you are not abusing the transmission as bad.

I have a ZDX with the 3.7 and the 6 speed auto that I have been thinking about this for a while. Not so much horsepower that kills transmissions as it is torque.
