3.2 to 3.5
 

whatsup people! So I'm a Honda mechanic of 2 years and interested in getting a 3G Acura TL 3.2 manual 6 speed. And was wondering what exactly is needed for a 3.5 swap. It's probably on here but can't get far enough to see it. So I have a 3.5 engine ready for the drop. Just want to know what else goes. Lucky me it was free. So what exactly goes in with this swap. Engines out of a 2009 Honda Odyssey. Thanks for replies.

A couple of comments:

• Given the 3.2 in the TL has 14 more horsepower than the 3.5 Oddy engine (but 12 lb-ft less torque), I'm trying to figure out why you'd want to make the change.
• Do you know for a fact the transmission mount for the 3.5 is the same as the 3.2?

well I'm just trying to figure it out really. I don't. I'm questioning what I will need to put that engine in. It's a 90k engine and the ones I've seen have 150-200k plus. I was also considering just taking the heads from the 3.2 and putting it on the 3.5. I'm just considering all options really. It's a free motor. And I'll be adding some stuff to it befor putting it in.But befor I do that I'd like to see what it takes just to have the motor in the car and running.

Also I have it outside the car. So suggestions are welcome. It will be a project motor. To explain better. I work at Honda. And I like the tl. Got the free motor. Looking to rebuild it as a learning project/swap. It will not go in lacking that HP for sure. But I'm not comfortable dumping some cash into a 200k motor so the engine I just recieved seems more reasonable as it's out/stored/ waiting to be played with.

Okay, I'm thinking it is time to page Doctor Skirmich; here's his profile page, you might want to PM him and invite him to the conversation:

All things considered, a 200,000 mile J32, assuming it was only moderately well maintained, is just barely broken in; unless there is something wrong with the motor, I'd leave it alone and drive it.

Well I wouldn't know. And that's my source for concern. As I'd like to buy a tl. And swap it within the next 6 months or so. So I set a time for work to be done. Any maintenance will be done asap. And I'd still like to project the motor over time so when I get bored of the 3.2 I can just drop the 3.5 with upgrades and have a whole new world of enjoyment. I'm not looking for a 700 whp car. That's too much. Just a very fun daily and more fun backup motor. Very picky in cars which is why I choose the tl. Also have 2 friends with stypes and love the looks

Your mail box is full but to answer your question if the motor is a j35a6 it will bolt up to the six speed. If it has vcm you will have issue. And it might not bolt up correctly since the transmission bell housing is different

So it turns out it's a j35a7 motor. Not much difference for the most part. Correctly looses HP for a minor gain in torque. So truthfully why even swap it out? Will I have any advantages of swapping it in down the line over the j32. Or is the j32 a better ride all out?

Back with a 05
 

So to add. I got a 2005 Acura TL with a 3.2. Squashed the j35 idea just stole some parts for use in the shop. Now I’m fixing some problems it has. And getting to the upgrades.

So im considering a cmc and clutch kit+ lightened flywheel etc.Not to sure what would be best. Would like to jump over 300hp. Adding an intake + spacer and j35 intake manifold since it was free anyway. Will do the j pipe stuck between xlr8,rv6,atlp. And any other suggestions I am open too. Please lmk. Rims are back to stock btw. https://cimg2.ibsrv.net/gimg/acurazi...d4deb7a12.jpeg

I just finished a J35A6 swap (05' Odyssey EX) in my 05' 6spd that I just picked up & it's literally a direct drop in. :thumbsup:

Nice. I’m not really into it tho. Got a lot of “it’s not worth it” so Im just going to work the j32 thanks for the info tho. Wish it was befor we gave away the j35

If you can do the work yourself it's definitely worth it. Basically a budget Type S, power wise anyways.

I’ll see. I’m looking for clutch options that would be nice with a lightened flywheel.

XLR8 has a clutch/PP/flywheel kit available. They have stated in the past that if you just want the clutch/PP they will separate it from the kit; however, I'm not sure that is still their policy. You would have to give them a call.:dunno:

XLR8-CS-J32-DAILY - XLR8 Clutch System - Excelerate's Honda & Acura Store - Japanese Performance Specialist

So I'm curious, switching to an Odyssey 3.5 from the TL's original 3.2 will drop the upper end power in exchange for lower end torque; by what measure do you consider it "definitely worth it"?

The high end may take a slight hit due to the Odyssey's cams being tailored for low end TQ but the increased TQ throughout the power band more than makes up for it. :thumbsup:

Hmmm, 14 less rated HP in exchange for 12 more pound-feet of torque; not sure that's enough to notice either way.

:spit:

Another thing to mention is that the 3.5 is now being ran off of the TL's ECU which has more of an aggressive tune compared to the stock Odyssey's tune. With that said the gains would only be increased over what the Odyssey puts out stock.

May not be everyone's cup of tea but it is plenty noticeable. :rofl:

Nope, not buying; I'm betting a stock 2004-2006 6MT with the 3.2 is faster than the same car with an Odyssey 3.5 in place. That said, there may be a minor difference in low end torque in favor of the 3.5 swap so partial throttle operations feel a bit quicker.

You may very well be right & but I'm not here to chase numbers.

What I meant by definitely worth it as you mentioned is that just the added low end alone makes it worth it, which I'm sure the majority of people use in their day to day activities. That said, shredding tire on comand doesn't hurt either. :chuckle: :thumbsup:

$1,149.00 for a clutch kit would be too hard for me to swallow, that is, unless you're gonna be racing. The LUK OEM replacement clutch kit from rockauto, $173.79 plus $164.79 for the 3.5 engine's flywheel (Cheaper than the one for the 3.2 engine!) would be good enough for me.

Yeah it’s a little pricey. I was going to just go exedy and go for something a little better the. Stock

Price out the particular Exedy clutch/PP kit (most likely a rebranded OEM LUK kit) you have in mind, that will get you that '...little better the. Stock' requirement, with the cost of a LWFW and post that price. I'd like to see it.

:ponder: Maybe you can leverage that info against XLR8's kit which would compel them to consider a special deal with you? Ever think about that??

I didn’t know that. I thought exedy was a brand of its own. What about spec? And I’ll try that. Whatever works. I mean if it’s really going to be over 1k for an add on it may not be worth it. Its a daily and I’m looking to enjoy it. But I will post ASAP with that trial.

Since the 'better than stock' part number to the Exedy clutch you have in mind has not been provided, here is an example of a rebranded Exedy clutch/pp kit from Rockauto that clearly shows the circle around the LUK name on the clutch disc:
More Information for EXEDY HCK1007

If you do the research you can find the 05 TL Aasco LWFW for $508 shipped. Then it is just a matter of finding your 'better than stock' Clutch/PP kit.

Well I’m still researching. And I don’t know which ones are that much better then stock that’s why I pisted on here for the info. Thanks for the info it’s helping me look at new things I couldn’t find. I’m new to the Honda game. This is my first Honda. Sorry for my lack of knowledge. Was in the vw/Audi world previously. Way different to me.

If you are going to stay normally aspirated, there is an argument that you really don't need anything other than the OEM LUK clutch kit & dual mass FW. This would be your least expensive route because you already have the 'most expensive' aspect of a clutch/pp/fw replacement covered, labor, as a 2 year Honda mechanic.

If you want to experiment, performance wise, and beat on the car a little more than normal, a heavier duty clutch and/or LWFW should cover you for the money, irregardless of what others post on here, and irregardless of your current normally aspirated status, I say go for it. Just beware that the old cliché of 'pay to play' holds true to get that 'better than stock' clutch and throttle response of a LWFW.

I'm not here to convince you either way, that's up to you.

I only suggested XLR8's clutch kit(s) because they are touted as 'better than stock' and give you a choice of Daily, Street/Strip and Drag categories. There are also other on here that have put these in their cars with good results.:shrug:

Good Luck!

Thanks a lot. Sounds good to me. I think Im going to listen and just go for a clutch/ pp/ and go for that 500$ flywheel. Any suggestions other then luk? Or should that be a good go 2?

FYI, the Exedy is the LUK repackaged with fancier advertising. You're just getting the same kit with an opportunity to spend more money for the same thing!

Thanks for that knowledge. Ima get the flywheel and the Luk Clutch probably in a month or two. I’ll post when I get it. In the mean time I’m looking for a 1lb or above weighted shift knob preferably black with the numbering on top any suggestions or quick links?

Aasco clutch
 

No, but then again, unless you're actively racing your car I would advise against a light weight flywheel.

dAng, $500 for a flywheel?

How light is it, and what material is it made from?

OP:
-A 200K mile Honda is like a 40K mile Audi, in terms of reliability.

-Buy your clutch parts from the dealer you work at, if you get discounts. Aftermarket 'OEM replacement' clutches don't always come with the same quality or spec of components, even if they're made by the same manufacturer as the dealer part. Honda writes their spec. The manufacturer (LUK) supplies a part to Honda with that spec. Doesn't mean they need to meet that same spec for clutches that are sold through another (non Honda) distributor. Honda also may not source bearings and other parts from the same manufacturer as LUK does. Feel me?

-Use Honda HT Urea for the bearing slides. Don't use just any grease...and defintely don't use anti sieze.

-If the TL comes with a replaceable release bearing guide...replace it!!

A flywheel will not change your shift feel.

The stock clutch, however, does feel like shit, I'll admit.

In my experience, it engages like...right off the floorboard. Like driving a tractor from 1867 or something.

If it engaged in the middle of travel like a modern car, I think it would be easier to drive.

Or maybe the car I drove just needed a pushrod adjustment.

No idea if there are any decent clutches available.

This question is a bit far out. But do any NSX components swap over?

XLR8 Clutch kit
 

I have the XLR8 strip clutch in my TL type S and I have to say it shifts so much nicer then the stock clutch. It is easier to take off in first and I don't have any vibration.I sometimes drive spirited and I have to say this is way more comfortable to drive then my friends integra and they have agreed.

Just clicked the link for XLR8's "drag" and "street/strip" clutches.

How is the pedal feel? Much stiffer than stock?

Are you reckless devils also doing a clutch interlock bypass? Or taking any steps to help out the engine thrust bearings?

Meh. I guess these engines sell for like $500. And YOLO and all.....

Its actually not stiff at all and not I have not done any of that. The car is stock besides the clutch, lowering coil overs and CAI.
