I'm pretty sure it fits in almost seamlessly. Paul (NVA-AV6) would be the guy who would know for sure though.

The 3.5 is a direct drop when built right, the problem is a 3.5 that is compatible with the 7th gen ecu and our trannys. Search you will find all the info on here.

^Can be built, but have to bore the block 1mm over so you lose boost capability or re-sleeve the block for the 90mm pistions which is not cheap. My J36 builds use J37 crank and rods. Oh and the J37 block will not bolt up to our tranny's, nor will the new AV6 3.5L bolt up.

well my cars automatic and i wanted to get the new 3.5 with 6 speed transmission. But id still have a problem with the ecu? a new engine and tranny would be really expensive right?

^To do a J36/6sp swap into your car would run about $8K from me.

Paul do you think the J35a3 from MDX 03+ will be direct swap on 6speed tranny and engine bay?
do you think I still need engine harness and ECU from TL-s 00+ to run the engine?or I can use from MDX.Thanks bro

A3 is a no go, the bolt pattern is different, the only compatable 89mm bore block for a 7th gen that I have personally used is the 04-06 J32A3 block, I have also heard the J35A6 from newer oddys "may" be a fit. I just don't like the newer oddy engines since the use FRM sleeves and all cast parts.

^No, the stock J30A4/5 ecu will run the J32A3 with no issues, now a J36 you will want to add a FIC, external FPR, and RDX injectors.

so only engine from 01-02 MDX and 02-04 oddy can fit on 6speed and our engine bay right paul,
Paul do you think is possible if we use crank and con rod from J37(07 TL-s) on J32a2 or not.

6th gens are a different ball game, yes the J37 crank and rods can be made to fit, but requires a bit of extra work to the crank snout....

lol. I meant it isn't going to happen realistically. Might as well buy an AWD car instead, since it might even cost the same. Who knows..


Accord AWD swap hasn't happened yet though..

I don't see the point of it anyways.

1. You could, but the cost wouldn't really be a worth it; a Comptech supercharger kit would probably be a better option.

2. Paul should be my new best friend.

3. An Accord with SH-AWD would be awesome, but costly enough to the point of pointlessness. Might as well try the fugly new TL SH.
