To build my 07 type s block or go with a j37 mdx block to build, I will be going m90
Looking into building my motor, I will be having cnc heads fully ported and built from p2r and now I'm trying to figure if I should build my j35a8 block or go with a j37 mdx block, this is my daily car and I rather spend the money to build the most power but still reliable for my auto type s

The J35A3 is a very desirable engine for 2G TLs and CLs of the same era, it will not bolt into your car.

Unfortunately with the M90 blower you'll see less than stellar gains. Through your auto trans I'd be surprised if you saw over 360whp.

I'm not sure what you want me to say, just comb through the hundreds of posts here regarding failed H5 transmissions and draw your own conclusion. The fact is, the H5 barely tolerates a stock motor, and will most likely fail sooner or later in stock trim; adding forced induction to your car will measurably shorten the life of your transmission. If you really want a forced induction 3G TL, sell your car and buy one with a 6-Speed manual.

Yeah, no one here is discussing 6spds, entirely irrelevant regardless of your feelings. But as a longtime person on this forum I was hoping that you would be able to make the distinction between the 04-06 trans and the 07-08. You're not speaking from experience, you simply stated a hypothesis to which I am telling you, is wrong. 500whp is a safe limit for the 07-08 auto trans with an accelerated maintenance schedule. I would be happy to cite long-term examples for you.

How do you plan to upgrade the transmission, OP?

Clearly your mind is made up; given that, why are you continuing to ask? Just put the damn blower on the engine and watch your transmission blow up; then you can be the member who cautions the next person with the bright idea of adding forced induction to an automatic 3G TL.

I've been at the ~420whp mark for two years now. Assuming a %20 drivetrain loss, that's about 500 crank. Have had no issues whatsoever with the transmission over the last +10k miles, and yes, I drive it.
A friend of mine with a similar Rotrex setup started at the 436whp and 440wtq level (stock motor btw) and drove that for two years. Upped the boost and fitted springs and retainers and now makes 492whp and has been for the last two years. Same stock auto Type S tranny. Again assuming a %20 drivetrain loss, that's over 600 crank hp.
Will the trans live a shorter life with more power? Sure, but it's not gonna break tomorrow. 1x3 every other oil change of Redline Type F, fresh switches every 40k and it will live a long happy life.

Nope, stock J35A8, just full bolt on. I wouldn't waste your money on building your motor since youre going to be using an M90 blower. Like I said earlier, that blower is the limiting factor here and I will be shocked if you make over 360whp with it. You're gonna wanna look into meth injection as heat soak and hot ass IAT's are gonna be your biggest enemy.

Lol!!! Yea these fools on this forum are a bunch of douchebags!! Lol not all of them but your regulars. J37 block will bolt right up to your auto or manual type s tl!! Doo what you want and don't let these fools stop you. They orginally told me a j37 wont work. That was proved wrong very fast. They like to read instead of actually doing the job. Bunch of fake mechanics that think they know evrything about a tl. 😂😂😂

Who told you that a J37 won't work?
There's no need to talk down about fellow forum members, we're all here to help each other out. Now, not everyone has proper experiences & more than likely are voicing opinions from what they've seen over the years on the forum.
I'm not talking about this specific build but "do what you want and don't let these fools stop you" has to be the worst advice in this thread. It's a good way to be humbled fast, especially on a 15 year old platform with little to no aftermarket support.

Wasnt intended towards you!! Cause i know you have actually done swaps before. But horseshoe and truongwhatever always telling people this and that. How this is bad and this wont work. They probably arent even tuned. They just read read read. Then think they know it all. Even gave smartass remarks like ima go to Hennessy shop. Like ctfu. Build something then have some positive input. Anything is possible, just how much you willing to throw at it. Ima keep saying do you and what you wanna do with the car. Nobody else opinion matter, cause in the end, its you driving it and you building it. Fuk what those knuckleheads say. Excuse my negativity but thats all i see from them 2 everytime i come on acurazine. Those 2 knuckleheads saying how this and that isnt good and this and that wont work.

Definitely understand where your coming from & I've had some experiences with them in the past. They're more opinated than others & aren't afraid to tell you how they feel. Sometimes they need to humble themselves but that's the perks of the internet lol.

Im the same way. Guess every tl owner has a way of expressing their own opinions. Just hate the fact that everytime im on acurazine, i see those 2 knuckleheads shooting down anything that has to do with a build. This wont work, this isnt good, thats a bad idea, etc. Cmon bro!! I know this isnt the best platform but its what we working with.

Just to be clear, how is cautioning someone about adding forced induction to a 3G TL with an automatic transmission when said transmission has a very well known history of being particularly fragile, saying "it won't work"?
Like it or don't, my comments were meant to be cautionary, NOT to say it wouldn't work.
