I'm looking to get out of my 2006 4-Runner that seems to always get 14-18mpg this summer. I have owned many Honda's and Toyotas over the years and cannot see any reason to ditch these brands yet.

I was originally looking at the early 90's civic models CX DX VX, however in the big city that 92hp is nearly dangerous to drive. I have gotten used to the 4.0L torque in the SUV.

The base model Acura RSX (K20A3) utilizes some tricks that might make it a fuel sipper in the right hands. It has an adaptive composite intake manifold. The VTEC mechanism is similar to the VTEC-E of old days where it runs on 12 valves and then jump up to 16 valve in "VTEC" rpm range. It has the advantage also of Honda's cam phasing on the intake cam only.

I have a bit of a soft spot for the K-series motors as I built a MR2 Spyder with a K20z3 swap a few years ago. The ability to tune with Hondata is also a very nice benefit.

Anyway long story short, I was just wondering if anyone has done it or heard of decent numbers coming out of these cars? It would seem the shape of the car is a decent starting point and the mechanics fit the theory as well, with some gear ratio changes (the Final drive in 5th is a little higher in rpms than ideal). The EPA fuel ratings on them is not great but I suspect it could be under rated or possible to greatly improve it with a different gear ratio and proper tune via the Hondata system.

Thanks,
