So my question is, I been hearing that I wouldnt have valve clearance issues with this block and the J32A2 head. But then I also heard I had to get my pistons machined so that I would have valve clearance, so which is it? I really don't want the 05' RL pistons, because I'm not looking forward to having a 11:1 CR with a 125 shot of nitrous. So my question is this, what pistons did you J35A4 swappers use?
ThinJim...have you been on lately? Haven't heard a response from you lately. My block is here, and I'm ready to take it to the shop. My head is waiting for me there.
Cliff notes:
Bought J35A4 block(Odyssey) and J32A2 head (CLS).......dilema, not sure what pistons to go for....

Wow, this is an extremely informative thread. Kudos to all of you guys.
Now I shall butt in with some questions of my own.
My friend has gotten me a J35A8 engine off the new Odyssey. So far, I haven't seen any mention of this engine (just the A4) and I was wondering how this would change things. I'm not familiar with the J35A8 engine at all.
Would it be possible to use my '03 TL-S pistons with the J35A8 block? Would the valves clear, and what do you think the CR will be? I haven't had a chance to take apart the engine yet or take pictures, but I should have time to do that soon. But until then, I figured I might ask you guys here.
My friend also mentioned that the VTEC oil solenoid is built into the A8 block, whereas it's mounted on the J32A2 block. Don't know what to do about that one...
Theoretically speaking that the J35A8 block upgrade is possible with the TL-S pistons and TL-S heads, what is the realistic power gain? Just curious.

What are the differences between the two blocks (J35A2 & J35A4)? Does the J35A2 have any negative effects if you do the conversion from the 3.2 to the 3.5? I just want to know because I may get the chance to get my hands on a 3.5 block and I just want to make sure it is the right one before I purchase.

It would be nice if we could get together a comprehensive FAQ on 3.5 conversions, I would do it if I had a clue . But for you folks tired of answering these questions or unwilling to answer them in a thread like this (I dunno why), how about it?
I'd be happy to at least host the FAQ....

I don't know what a heck is J35A2.
'05 RL - J35A8
'05 Odyssey - J35A7 (EX-L and Touring models: equipped with Honda's cylinder deactivation system (VCM))
'05 Odyssey - J35A6 (LX and EX trim levels)
'03-04 MDX - J35A5
'01-02 MDX - J35A3
'02-04 Odyssey - J35A4
'00-01 Odyssey - J35A1
A5 crank won't work on J32A2 block (tried and shaft is too short to fit CL-S crank pulley),
not sure about A3 but A1 and A4 fits fine.
Here is my:
J32A2 block
J35A4 crank/rods/bearings
J35A8 pistons/rings
J32A2 heads
J32A2 slightly ported & polished lower manifold
and '04 S2000 injectors

There's no need to use the J35 block. I've heard the J32 block has better cooling properties than the J35 block. Save yourself some cash and just put the J35 parts into the J32 block.

the 01-03 cls block and o1-o2 mdx block are the same part number. as for the oddessey, we never looked in that direction for a comparision. the 03-04 mdx block is different and will not work with our car...the transmission attachment point is different. The crank out of an o3-o4 mdx is the same as the 05 RL, same part number. a forged steel design which is much stouter than the previous years. And yes, the crank is slightly shorter, the snout is shorter, the crank fits the into the block with no issues, but there is a way to make it work properly as my engine will use the 03-04mdx crank.

You can acutally open the valve pockets up with the pistons in the block. You need a cls head that is completly disassembled. You would have to find a valve cutter tool with the shank being the diameter of the valve stem, and the cutting part the diameter of the valve. you put the cutting tool into the head and place the head onto the block. Put a drill on the shank/stem and go to town. .. You would have to devise a jig of somesort to be sure the cutting edge does not cut to deeply into the piston. .... it's complicated to explain but sure beats breaking down the motor and can be done more cheaply that taking the pistons to a machine shop.

Damn TLS
see you Cl guys have all the fun. One 3.5 L upgrade, a few turbos here. Us ova there at the TL have nothing. Ever since Austin519<---- the old skoo people might kno him, left the TL site. Its been DRY. There is one turbo production that is taking like 4-5 months but damn I wish some TL or TLS people will actually do something crazy. I mean the TL side we got 2/3 crazy looking cars such as unique TL and njzprettyboy but nothing like the 2 crazy hooked up CL ( i forgot their names but Yall know what I am tlakin about) I am so jealous that the CL modification wise is so far ahead of the TLS. But good job guys.

Nothing, yet I'm going to wait and see what kind of numbers the rest of these guys make before I decide. And even then I'm not sure if all this is worth it for an additional 300cc's. Maybe if the CL-S is retired from daily driver, but I don't see that happening soon. I've got another project for the CL-S in the works to keep me busy over winter.

woah, didnt know this thread was still going...well just an update for you guys, the block goes to the shop this Saturday. I'll keep you guys posted on the swap. I'm looking to have it done for the meet, but that's a long shot. Not sure how long it'll take to get my 6 speed together...

What do you guys think of this setup?
'03 TL-S
J35A8 (the new Odyssey) pistons, rods, crankshaft, and the accompanying parts... in the factory J32A2 block. Sounds simple enough, doesn't it?
I mean, after reading the recent posts on page 3, it is my understanding that the block itself is the same between the J32A2 and the J35A8. It is the pistons that make the difference in the displacement (stroked, same bore)??
How would the J35A8 pistons work with the TL-S valves? I'm very very close to getting this done.

As I posted:
'05 RL - J35A8
'05 Odyssey - J35A7 (EX-L and Touring models: equipped with Honda's cylinder deactivation system (VCM))
'05 Odyssey - J35A6 (LX and EX trim levels)
'03-04 MDX - J35A5
'01-02 MDX - J35A3
'02-04 Odyssey - J35A4
'00-01 Odyssey - J35A1
'05 Odyssey - J35A7 (EX-L and Touring models: equipped with Honda's cylinder deactivation system (VCM))
'05 Odyssey - J35A6 (LX and EX trim levels)
'03-04 MDX - J35A5
'01-02 MDX - J35A3
'02-04 Odyssey - J35A4
'00-01 Odyssey - J35A1
So, you have new Odyssey block you speak of which is either A6 or A7 and same as A5 except the material used on internals. And as far as I've seen on A5 it might not bolt up your transmission and other parts from your car won't fit. You can try to confirm, but I'm 99% sure it won't work.
Therefore, your best scenario is A4 crank/rods/bearings ($1000) which is Odyssey '02-04. And everything fits right in into your J32A2 block. If your block is Type S you can use existing pistons or I'd rather still order it new ($180) + rings and that's it. Labor of course is extra

Self-learning experience through previous setup and current 3.5L swap
And certainly through the shop who performs mentioned work.
