Ok i guess u 2gen guys could answer dis question..i want to know what bolt on internals i could put in my j30 to turn it to 3.2...and can i change my IM to a 3.2 intake manifold would it bolt up with no problem...so what crank and piston etc. I need to use..one thing can the 3.2 TB bolt up on the j30 as well?.....1gen people cant answer so i went to u guys...

anyway's you can buy CIVICDRIVER'S old parts, proably for dirt cheap too

i would think every thing should basically bolt right in, only thing i might say would be is the distribuater, but none of the parts relate to that, so should be no problems with it (other then maybe clearence issues around the distribuater with the intake, but i don't think it will)

Nope, don't have 'em. Only thing I still have is the clutch setup.

,so what happened to your stock parts then, did the shop not give them back to you??? (and don't you still have your stock manifold though, that is't suppose to be up in the attic or something, [that you were suppose to get measurements from :shakehead])

The cams, two broken rockers, old pistons, rods and crank were so worn it didnt make sense for me to take them. I was offered them though.
And yea, I still have the manifold, but its cold in my attic :ghey:

(what is the engine code on it; what vehicle it is from would help too)

as far as i know the blocks are indistinguishable/interchangeable -- the ones listed in the oringinal post. I know people who have done the 3.5 still use their underdrive pulley. I don't see why headers wouldn't go right back on.

I tried reading through this, but I was kind of confused, so maybe someone can just answer this question for me..
If I were to do a CL-s engine/tranny swap into my 2g tl-p, would that all bolt in pretty easily?
And then before I put in the CL-s engine, if I were to build the engine into a 3.5L, would that be possible? Through the rl pistons or whatever it is exactly that I'd need..
So then I would have a 3.5l CL-s engine, that is the final result I want. Or 3.7L if that is possible.

The S motor will bolt in, but not wire up.

So I guess what I am really asking is that if I were to buy a CL-s engine and tranny, those would bolt in?
And then if I wanted to change it to a 3.5l I would then have to use the bottom end of an RL or Oddy engine?
What I want to do this summer is buy the CL-s engine and transmission I found, convert the engine to a 3.5l, and then put in all my bolt-ons, then install that. Is that possible?
Even if the ecu is swapped and I buy the wire harness? What else would it take to make it all wired up correctly?

you'll have to take a look at this first if you haven't already:
https://acurazine.com/forums/2g-tl-1999-2003-98/6-speed-conversion-591872/
You would basically do exactly what's in that thread but put different crankshaft, rods and pistons in. I don't know if it would be cheaper to just buy the internals and put those in or buy a whole Oddy/MDX short block and just change the pistons.
I don't think your headers will bolt on unless they have the bend in the rear meant for the 6speeds. Everything else should be fine.

question
Hi im kind of new to this site. i just bought a 03 cl type s 6 speed. i want to make y car a 3.5 liter with the mdx crankshaft and piston rods. If I use Rl pistons will I be able to use my stock computer? I understand I will have .5 more compression with the rl pistons. WHat if i use the cl-s pistons? also non of this will throw off the balance of the rotating assembly so i can use the stock flywheel and all that from my stock type s correct? i have a spare j32a2 and an mdx block. I just want to be sure before i put it together. Any help would be appreciated

your CL ecu will be fine. May want an adjustable fuel pressure regulator. Use the MDX crank and rods. For pistons you can use your CL pistons for lower compression of RL pistons. RL pistons will yeild slightly more power. Everything else stays the same.

niceeee i appreciate the help. i want all the power i can get so i can use th rl pistons with the stock computer also? I work for a machine shop and i can port and polish my heads and inake manifold for free. is it worth it? how much power will i gain if i port the both?

yes the stock CL ecu can handle the 3.5 upgrade...many have done it. Like i said the FPR will help to keep your air/fuel where u want it. Definitely port your intake manifold and runners. Once you stroke the motor it begs for more air. If you really want a crazy intake manifold, talk to NVA-AV6. He is a builder in VA and he has made an intake manifold for a guy here with a 80mm throttle body. here's his link:https://acurazine.com/forums/2g-cl-photograph-gallery-53/my-build-thread-bordering-more-bs-56k-beware-769245/

i got 04 ody engine all i need is CL/TL Type S heads and CL or RL pistons ? but what i get CL-S heads from auto ? i know that there is probably diff between CL auto/manual heads. im asking that bc i want to build the engine first and then swap it over and also i want to do TB service on that motor as well.

nice! i think it would be cheaper for you to use what you already have from your motor. And yes i believe the auto is different.
Have a shop complete the bottom end on the oddy engine - new pistons/rings, hone, new bearings on the crank - then drive your car in and have them pull the engine and swap your heads over, reinstall. That'll save you from searching for and buying new heads. Then you can sell your complete CL block for some $ back. You shouldn't be without your car for more then a day or two.

Im sure it would be cheaper but i want to do motor myself with help of my friend mechanic. So it would be nice to have spare cl-s head so ican make sure that everything is gonna be ready and tb service done as well. Then i would go to shop to swap it over. That would save me alot of money. But still i need those heads.

That way you could replace valve seals,give a quick lap to the valves,and atleast gasket match the heads.

that's a J35 (3.5L). J36 (3.6L) is a J37 crank i believe. Also i don't think you can port the 09+TL manifold because it's magnesium. The reason it's better is because of the material and it already has larger runners.

wait a secc. What is the difference between cl-s 6 speed heads and tl-s auto heads? I have all the parts and im ready to build my engine. I have a cl 6 speed and a spare tl-s auto engine and was planing on just builing the auto engine and swapping it into my cl?

What im saying is that I have a 03 cl 6 speed Car. I have a spare engine from a 02 tl type s and i wanted to do the 3.5 conversion to that engine so my car wouldnt be off the road. SO are the Engines not compatible? or can i do my build to the Tl engine and use whatever parts from the 6 speed to make it work?

You can use TL S motor but you have to swap the cam and gear sensor and gear from manual head. Or just simply reuse manual heads. But thats all. You can reuse block it has iron sleeves and pistons but i would go with RL ones. All you really need to build spare motor is heads bottom from odyssey or mdx on the first page you have all the info you need. If you want save money you should reuse CL pistons but the have different compression than rl ones iirc that makes you able to run regular gas if you want.

ok cool its a good thing i can use at least the castings of the heads because i ported them at my job as i work for a machine shop. Heres another questions......What is the difference between intake manifold and thottle body on the automatic and the manual?. I really appreciate this help.

VSA isnt part of the throttle body on the autos, its what many people mistake as the "second" throttle body. You just remove it and the TB and intake are the same.
