Long story short I cracked my oil pan on the highway and had to drive a little further than I wanted to while the oil was dumping out of the car. Replaced oil pan and drove the car, seems like I need a new bottom end now. Considering just doing a 3.5 conversion while I have the chance.

Someone correct me if I'm wrong. But for the most part I just need mdx or odessy crank and then use rest of type s stuff ie. Rods, pistons, rings and type s heads? Stock j32 block? What about the computer? Would it adjust itself or would I need tuning?

Honestly don't wanna dump this $ into the car especially being this old. But at the same time I don't wanna junk the car because it's well taken care of, as of right now 101k all original miles. (Granted I cracked the oil pan and need a new bottom end) Interior is still perfect, probably could use a good waxing on paint but the car is in great condition. Pretty much it's whole life has been in a garage and barely driven.

Not sure if the ogs in 2nd gen community are even around anymore but figured it would sure clear up some questions I have

It will be cheaper just to buy the entire J35A3 engine and swap it in..
If you didn´t have a Type-S to begin with you don´t have the ECU to take advantage of the Tune and Higher Redline anyway so there is no need to get the Type-S Heads.

vip_inspire

Car is originally a type s

Skirmich

Do this:
Get the J35A3 (Complete Engine)
Swap your Type-S Cams out of your J32A2 into the J35A3
DONE.

Jeez dude.

Trust me bro it sucks. Slammed car plus highway construction doesn't mix

Stock mdx engine? Would buying the mdx motor with j32 Cams be comparable to the stock j32? Of course torque would be better with more displacement.

Can I just do mdx short block and add my heads and all the extras from my existing j32? Trying to at least make some more power while I have the chance

Have you confirmed the bolt pattern for the transmission between the J35 and your current J32 are the same?

Iggy

Same block so yes

horseshoez

iTrader: (2)

Ummm, no, not so "yes". Case in point, the 3.5 from the TL Type-S will not bolt in because it has a very different transmission mount pattern.

Iggy

There were no 3.5L TL Type-S production models for 2G. Unless I'm in the wrong forum.

This thread is about J35A3:

• 2001-2002 Acura MDX
• 2004-2007 Saturn Vue also referred to as GM L66

And the J32A2:

• 2001-2003 Acura CL Type-S
• 2002-2003 Acura TL Type-S

My point was, not all J35 engines will mate up with the transmission in a 2G TL, what I don't know is if any J35 engines will mate up with that transmission. So far nothing you've written answers that question.

Iggy

Skirmich answered already above but if you need
More concise guidance, the J35A3 has the same transmission bolt pattern as the 2G TL/CL.

Skirmich

This is a 2nd gen TL thread in a 2G gen TL forum... So the answers are specific to the 2G TL
I also clearly stated a specific engine called J35 "A3" there is no typo there, Nobody say buy any Honda or Acura J35 and YOLO!
The only J35 that will fit has to have an "A3" in the code name as in: "J35A3" also known as 1G MDX Engine. It also has to come from the EARLY 1G MDX as they changed to the retarded Header-In-Head system in the bumped up engine from the MDX 2003 and up making the potential power making lower with the lack of Real Headers option.

More info:
The J35A3 uses exactly the same Block as the J32A2 (They even have the same part Number block) so to Answer your question.
YES the J35A3 is DIRECT BOLT ON to the Stock B7WA Transmission or AV6 Transmission or The 6 Speed Manual for the 2G TL/TL-S/CL/CL-S.

Thanks, good to know.

Skirmich, all of that specific info. you listed above is excellent and horseshoez has been recently exposed to it in a very similar thread discussion on the 2G CL side, it's just not retained.

https://acurazine.com/forums/second-...advice-960284/

Skirmich

Perhaps he didn´t know the CL and TL are identical drivetrain wise.. Considering most of his info relies on the 3G TL and the 3G TL didn´t share with anything.

zeta

iTrader: (1)

Perhaps.

However, when there is clear discussion in regards to bolting a J35A3 to a 2G CL-S 6speed, which will take either a J32A2 from an auto trans TL-S or CL-S, with the modifications mentioned, as you know, paying attention to detail is important, just saying.

Karanx7

Wow, you're really arrogant for being so ignorant.

I would recommend getting a J35A3 and swapping in the cams. Sure you can swap the whole head and even machine the head for extra compression, but I think the swapping just the cams is very easy and you don't have to mess with the head gasket.

horseshoez

iTrader: (2)

I guess that's being better than a horse's ass.

If you take my comments in this thread in context you'll see I posed it as a cautionary question and not a statement of fact the two engines were not interchangeable.

Karanx7

iTrader: (2)

Hmm, sounds like a horse's ass to me. Also, your "cautionary question" definitely seems like a statement of fact. As far as context goes, you should look into it yourself as everyone in this thread was on the same page except for you, buddy.

horseshoez

iTrader: (2)

Yup, just as I figured, you can dish it out but you cannot take it. Time to grow a pair buddy.

Iggy

I'm not sure if it is intended or not horseshoez, but you do come across as kind of a jerk.

horseshoez

iTrader: (2)

Really? Nope, not intended; I was simply trying to look out for the best interest of vip_inspire, I didn't want him to buy a motor which wouldn't bolt up. I learned both the J32 and J35 blocks were cast with different transmission interface patterns; thanks for the schooling.

Skirmich

The thing to know here is that "J35" does not equal EVERY 3.5L out there, The J35 has been around since 1999...
Engine code numbers are very important.. For example:

J35"A3" = MDX Engine
J35"A8" = RL/3G TL-S Engine

Both are 3.5L in displacement but they have very different Transmission bolt patterns.
There are also different heads used for the same block which also change the engine code number so for example:

J35"A3" has the same transmission bolt pattern thus the same block as the J35"A5" but.. The J35"A5" has those stupid Headers-On-Head system.
So they could bolt-on for the 2G TL transmission but the exhaust system will have to be severely modified.

horseshoez

iTrader: (2)

So does that mean the J35A5 will bolt into a 3G TL, which if I'm not mistaken, also has the header on the head thing?

Karanx7

iTrader: (2)

I don't understand. You got schooled and called out for being an ass, not me. I couldn't care less about what you think, sorry.
I think he just thinks that he's smarter than he is.
Yup, just as I figured. You like to give advice while knowing next to nothing. Hopefully you learned something, buddy.

Skirmich

Nope.. The 3G TL has updated transmission bolt patterns starting with the J32A3, The J35A5 while having the same retarded Headers-on-head system as the J35A8 will not bolt on to the transmission because it has the old transmission pattern of the J32A2 which shares the same block.

Skirmich

Mod Hat On...

Please horseshoez and Karanx7 lets just stop this fight right here for the sake of a healthy thread.

horseshoez

iTrader: (2)

Thanks for the info.

horseshoez

iTrader: (2)

No need to tell me; I've already moved on.

Karanx7

iTrader: (2)

Wasn't aware it was even a fight.

vip_inspire

So for the sake of argument I assume I can bolt on j32 heads on the j35 block. I'm thinking type s heads will flow better than mdx/odessy heads. Someone correct me if I'm wrong.

As far as tuning is concerned what computer would I run with the 3.5 conversion and type s heads?

What computer would be ran using j35 with type s Cams?

If I was to just buy parts and rebuild the engine. All I would really need is the mdx/odyessy crank right? J32 pistons, rings, rods, and bearings?

Skirmich

IIRC someone says the Heads are actually the same on both engines the only thing that differentiate the J32A2 is the Camshaft which is more aggressive for Top End Power. So you could swap the Camshaft or the entire head if you please, The important thing is to run the J32A2 Camshafts.

The ECU you want to run is the Type-S ECU because of the extra oomp of the Camshafts it is tuned for Top End Power and the 7K RPM Refline.. It also has a more aggresive VTEC engagement.

As far as specific parts I dunno because most people running that setup do not bother by going single parts they usually buy the entire J35A3
