Ok, some of you fellers know that I'm a sprayhead and love my bottle. After FINALLY talking some sense into my wife, we (I) have decided to install a nitrous kit on the MDX. Being that she too likes the TL with spray and also is secretly turned on by the power, she's become more of an addict than I am. Always encouraging me to "pass this slow ass car and hit the nitrous" or "show this dude what's up"...it's undeniable.

Not really, most of what I just wrote is a load of shit. It really took me weeks to convince her this MUST BE DONE! So far, what I've learned from most of the other members here (mostly that Paul dude who knows all there is to know about these motors) I've pretty much concluded that this motor in stock form should be capable of handling some pretty heavy numbers.

I need some opinions and thoughts on this. Year of the MDX is a 2007.

In for engine blowing up and LULzing at you.

you'll need to take precautions and put some watch dogs in place.

like a knock monitor and such.

I really hope this response is meant as a joke...


Of course, this isn't my first spray rodeo by any means. Im more or less looking for any known weaknesses on these motors and also their capabilities. I know they very stout in both build quality and design but I'm looking to really be between moderate and pounding the shit out of it. I pound my TL but this one I'll be treating somewhat nicely.

If you're rebuilding a 3.7 to fit, make sure it's done by someone who is very familiar with the J series. Also, make sure to follow strict break-in procedure. NO nitrous obviously for first few thousand miles. And most importantly, dyno before and after.

Karanx, this is meant to be installed on a 3.7 in a MDX.

Ooooo, I see. Why put it on an MDX?

To go faaaaaaaaaaaaast. :-)

It's unique and I wouldn't mind spanking some people in 3rd row seating AWD SUV with the trunk full of groceries, 4 kids, 2 adults and all the luxury of a Cadillac! Lmao....kidding about the kids part. But I've always wanted to see what this thing would do with some more power in it. Most people I don't think understand how fast these things are in stock form (even with AWD) and that's only 300hp. Most of that power definitely comes from the torque cause it pulls from 2ooo rpms and up. It actually feels like power somewhat becomes stagnant above 48oo rpms TBH...

^its the same J-motor.

if you have experience (isnt your first rodeo, cowboy) then go ahead and do it.

its the same j-motor.

Woo-peesh!! Ye haw!!!

I hope you have proper brakes and tires to go with it.

Ah crap, got so carried away with cowboy noises that I forgot to say: I know it's the "same" J motor BUT with an all forged bottom end (and directed towards someone who might know), what's the POWER HANDLING CAPABILITIES of it?

justnspace

iTrader: (1)

^no one knows.

the J32 and J35 are reaching goals of 500hp(with a turbo) with out anything breaking other than axles and transmissions.
the J37 should be right there with it.

yungone501

iTrader: (4)

Oh cool, that makes me feel a lot better about: (firt of all) spray the crap out of my little 3.2 to the point it makes me feel like at any second the bottom will fall out but it just keeps taking it! And secondly, that the J37 should take quite a bit more than both the J32/35 due to the components contained within. I'm guessing this motor may easily take 600 going by the figure you gave above but I'm sure it could be pushed even further if closely monitored...

Keep in mind that the J37 block is bored to the service limit to get the additional capacity. You have to be very careful or youll end up having to resleeve it.

I thought that was only when throwing the 3.7 bottom end in a 3.2/3.5 block? If thats true, why would Honda build a motor that has the same sleeve thickness and use forged components? And that was an actual question, not an argument.
And if they're the same thickness, wouldn't they have atleast made them out of a stronger metal or combination of metal and "X" material? Where or how can I find additional information on the specs of the block/ components?

And to the feller who said needing better tires and brakes way up'er ^^^
Well, brake improvements I could agree with but the tires....I'm very confident in this thing having no traction issues in any aspect of that concern. AWD with stock power alone can surprise most people in the passenger seat from a dead stop.

iTrader: (9)

Ill try to find the source on that info. I do know that the cylinder liners on the 3.7 are aluminum, not cast iron. So that could be another potential weakness.

Justnspace, why would thank a response like this? That's ridiculous...

And civic, thanks for ruining my highspirited idea...I'm gonna go hit the NOS on the TL now to make me feel better. :-(

OperationDarkie

iTrader: (1)

Why?

Sonnick

Because Morgan offered to look up the info for you.....

Ruined your idea? He just saved your a$$ from your wife after you blew the motor on her MDX and ended up like the guy in Karanx7's sig.

Alright. Bought the kit and have it right next to me as I'm typing this response. Tomorrow (hopefully) it will be installed. Many people say that running 125, 150, 175, and 200 shots on the TL would not make it very long. You know what you're doing and how to do it, these motors (most motors) can do ALOT more than what most people say/think. Am I saying that it's not a crazy thing to do? No. I am, however, a believer in a crazy being a big part of this hobby. Without it, most of us wouldn't be here on Azine continually looking for ways to boost power. ;-)

Re and Cheryl

I would be less worried about how much abuse the motor can take and more worried about how much abuse the tranny can take. I would go conservative if I were you.

I figure if a known poorly designed transmission such as the 2g TL can handle 470hp, it would be safe to assume the mdx trans should be fine running less horsepower. If anything, I feel it's weakest link is the AWD system. I've heard more stories of those having issues more than anything else.
