J35A8 vs. J35A8
I just replaced the timing belt in my 07 TL Type S. it has 170K mikes and this is the third timing belt. Previous owner replaced at 140K.
I initially installed it with 1 tooth off, and after running the engine in the garage, and getting the codes, I reinstalled the belt. I then took it around the block and all seemed fine. She was running great. I drove it less than a mile and as I pulled into the drive way, She died with a pop.
The timing belt stripped out at the crankshaft gear - See pics -
Now the Fire wall side camshaft wont move, and I'm betting I've got bent valves.
My question is : Are all J35A8 engines the same? I found a 2005 ACURA RL Engine 3.5L for sale. It is a J35A8, just like my 07TL Type S. Can I drop this long block in and bolt on all my external components to it?
Thanks guys for the help
Brand new timing belt. 8 minutes of run time

RL j35a8 will bolt up and make a little bit more power due to better camshaft. If you can get an RL motor I would do that over a Type-S. Not sure if you are At or MT, But you might have to change some stuff over

It has been done before, a guy swap RL motor to his TL-S and here is the thread. He does mention some component will needed to be transfer from the old motor for the swap.

2007 TL-S J35 rated 286 HP, 2007 Acura RL J35 Rated at 290 HP "SAE Correction method" all of that being said its 4 HP differences. I don't know where you guy get the 14 HP from

still a good upgrade for 4 hp and more TQ throughout the area under the curve since the RL camshaft were more aggressive to move that 2 ton tank. I have the camshaft spec sheets TLS VS RL somewhere

they used to be rated for 300 crank hp before they changed the rating. :p in 2006 which dropped it 10 crank hp

Oh so you mean our TL magically drop HP from 270 to 258? :P .... LOL now back to topic, yes I know the RL has improved TQ band on the low since I drive that 2 tons tank every day now

The block I am getting is a J35A8 out of a 2005 RL SH-AWD. I don't think there will be an issue, but I am going to be thread searching like mad to find any differences, in the bolt on component items. Im happy for the increase in power and torque, but honestly Im happy getting a 105k motor to drop in my 185k car. I should be able to get another 100k out of this thing, before I hand-me-down it to my kid.

I would get 105k service done and check for the oil pump prior bolt the new motor up. You have access to everything when the motor is out.

Yes, I was planning on a full service - or as much as I can do. Since I just did that on the engine that blew, I have a good amount of new parts to switch over.

The bigger question is... What in the world happened to the T-belt? That is far from normal!!!

I can't even imagine it being more than an hour of labor. I mean, if he has both engines out of the car, it should be rather quick to swap everything over. I wouldn't do it for the performance upgrade alone, but in his scenario, I think it's a wise move.

That crank pulley is a pain in the ass to get off the crank without doing the starter blimp. There is a tool on amazon that makes it easier with an impact gun due to the larger area it hits on vs a standard impact socket.

I'm an old pro at the crankshaft pulley. I have 2 breaker bars and also a nice airgun.
As far as Commiefornia smog laws, I don't know what your talking about.... this is the original engine. I don't even wrench, bro!!
And, I'm getting the J35a8 with 105k for 800$
pulled from an RL with all wheel drive.

they’re the same exact engines. The RL doesn’t have different cams then the 07-08 TLS. Only difference in hp numbers is where they took them from in the rpm range. They make 286 @6200 310 @ 6500 who knows how much at the 6900 rpm redline.

Bonus question since you know everything. Why RL has extra 4 HP over TL-S?
