a winter project huh? Interesting.

 

did you ever talk to jimmyrecluse on v6p, he gave me a link to a 6spd last year for 1200-1400, he might still have some connects...

 

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.

 

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.

 

I can't answer any of your J35A8 questions... however the potential power is amazing. TypeR's car makes as much power as a supercharged J32A2 running 3.5-4.5psi!

 

Details on TypeR's setup? Thanks, Steve.

i had a broken injector with a broken green cap...so i broke it all the way off and the inector looks identical to your S2K one

 

can u use the CL-P pistons to get lower CR? 9:1 i believe?

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....

 

Yep, they're fit right in (see below)

 

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.

 

By the way

 

 

Yep, that's why I use J32 block with better sleeves and added J35 crank/rods. Pistons are optional with 4 choices availble as I mentioned before.

 

I want one

 

All you need is $1000-1100 ( J35 crank/rods/bearings) + labor.

 

Woah back up... it only cost you $1100 for the build? Or is that just parts?

 

Parts only.

 

Labor doubles that? Triples that?

 

Since I sold my forged block, I had to buy new '03 J32 block ($500) + new '05 RL pistons ($300)

 

If you got connections, they should do it for $1500-2000.
Others who knows.

 

Pistons were only $50 each? wow

 

wait if you use the j32 block wouldn't the displacement still be 3.2 liters?

 

J35 crank/rods make 3.5L not the block

J32A2 - 89mm x 86mm
J35A* - 89mm x 93mm

 

ahhh gotcha, makes sense now.

 

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.

 

So if I could get my hands on an '01 MDX shortblock assembly I could just bolt up the top half of my J32A2 motor and be good to go? Or i'd need new pistons wouldn't I?

 

Just the blocks as stated above are the same. The pistons out of the mdx will smack the valves on the cls heads, mdx has 35mm diameter valve...cls has 36mm. you could go with the rl piston or use the cl type s piston, depending on compression needs. I'd say stick with the cls piston as the rl uses a oil squirting method to cool the piston which brings detonation under control. Yes, your top half of the 3.2 will bolt right onto an o1-o2 shortblock. they use the same head gaskets for your next query. you'd have to change the pistons or have the valve pockets opened up.

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.

whatcha gonna do?

 

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.

 

^ tell everyone in the TL side to come join the fun. it's only one click away.

 

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.

 

Damn u guys are smart! How did you learn all this? Where can I go to get the knowledge?

 

they went to lincoln tech

 

Nope, read again

As I posted:

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.
