for guys with 3.5 motors - silly question but serious one
I am thinking about dropping a j35 crank and rods into my spare j32 motor. already have headers, cai and underdrive pulley.
what type of mpg are you guys getting? this is still planned for my daily driver and i do drive 110miles round trip every day.
I am currently averaging 25mpg hand calculated on last three tanks before the header and underdrive. On my TL i was averaging 24mpg with header, CAI and underdrive pulley.

true but in california - to be legal i would have to do a california air resource board inspection and treat it as a motor swap that will be inspected.
If i swap crank and rods into my spare motor it looks stock =) as it would still say j32a2 on my block

I have a J35a4 in mines with a hfcat, icebox, headers, lw crank pulley and i get about 24-28 mpg average on long trips. 90% of my commute are city so my average is usually 18-21 mpg.

The J35A3 block from the '01-'02 MDX is the same block as the J32A2, plus uses better internals that the J35A1/4. People gravitate toward the Odyssey engines because they're more common, but a quick search on car-part.com will likely reveal a J35A3 in your area,

Well I moved the spare motor around this weekend. Took the intake manifold apart to see what it looked like. Lots of casting flash.
I can take pictures of the blocks back to back later on

I would. The driveability difference of the motor is worth its weight in gold. Its not like a Chevy small block, but there is so much more torque than the 3.2 the useful driveability is much more enjoyable. You wont have to use the gas pedal nearly as much to get the vehicle motivated. My car will pass on the hwy as fast in 5th as the old 3.2 did in 4th if not 3rd.

On the hwy I picked up about 2-3 MPG after the 3.5 swap(town 21-26 HWY 26-30). J32A2 and J35A3 share the same block and heads there are a few internal parts and accessories that are different. You can be a grandpa with gas pedal and still be flying.

not a grandpa yet but I normally drive like one my commute due to traffic. =)
With the larger displacement .. No difference in rev happiness ? My motor still seems sluggish even with header, intake, UP.

for me since I have the original 3.2 motor with blown head gaskets -
I would need new gasket set, 3.5 crank and rods from a j35a3 or a4
Part of it is about scheduling as I have my shop full of old motorcycles that I am parting out first. Once I clear them them then its time for the next project

Im sure this has been covered on here before but is there a reason people use the J32A2 cams when doing the 3.5 swap and not just leave the J35A3 cams and run it?

6mt swapped..smart
The j35 cams are spec'd more for low end tq/power that you would expect in an SUV where the j32 cams specs flow more air up top/and make more peak hp
