Men are competitors by nature...even if it means making some sh*t up! 
In all seriousness, I'd like to know what this intake entells. I'm a sucker for custom intakes. Something about metals fabrication for means of increasing horsepower just really makes me go overboard.

Whoever made that looks like they came from a custom r/c building back round.
The rods on that thing look just like some alloy tie rods for r/c cars/trucks.
Only thing that turns me away from that type of setup is theirs a higher chance for vac leaks.

With what they can gain over stock setups its well worth it. with a quality build, Vac leaks would be the least of my worries. Tracking them down would be easy too.

If you guys are interested in custom itb's I have a company u can go to that will make them specific to your needs/engine mods, etc. it's pricey, but the best apparently, and they have been in the game for 30 plus years or so. I can get u the info when I get home if you're interested. It's roughly 3k plus.

Fuck it I guess I'll let the cat out of the bag and give you guys a idea of how my new manifold setup will be. I will have to use after market fuel rails and regulator (already have). Anyone like the obx or p2r fuel rail setup?
Other than this one being a single throttle body setup it will look very similar to this just smaller to fit in between our heads with two less cylinders. It will have a open lifter valley exactly like it also.
This is how it will look with the dual throttle body plate. Minus the closed lifter valley part and dual injectors.
The inside will look similar to how this looks also.
I'm not saying mine will look exactly the same but it will be very close. Very typical aluminum sheet metal V8 intake manifold setup. There's no sense keeping the oem lower runners because they can only be bored so much since the walls are so thin. I want to do something never done before. Hopefully it proves to make more power and look good at the same time lol.

Honestly after looking at the engine closely on the engine stand I don't know why something similar hasn't been done before. It makes more sense to do it this way than to use the oem lower runners. They will taper slightly.

I was hoping I could just buy the spacers themselves. If you have the spares available, I will gladly pick them up. If you don't, that's alright as this trip to Europe will force me to take a slightly different route in my build. Just let me know, I fly back tomorrow and will be starting my build shortly after my 2 piece bbk arrives (there's been a 6 month delay as is already, bah!)

I just wanted to let you know I have not forgotten about this. I landed back in the states yesterday, but will be in OC till the weekend. Once I get home to Corona, I will post the details. The info is saved onto my personal comp back home. I will keep you guys posted.

Just a little update. I ordered a J35A3 engine today off car-part.com. Once that arrives I'm going to start getting the ball rolling. I'm selling my modified comptech headers to gerzand so he can put them to good use once he does his head swap. I'm also going to go the long tube header route and have custom ones made while I have the engine out.

A little update. I picked my J35A3 engine up today. It's a lot cleaner looking than I thought, for the price I paid lol. I removed the oem exhaust manifolds and plenums. I'm going to give the mdx velocity stacks and intake manifold spacer to my uncle for his engine. He bought my old upper intake manifold setup. I have to sand blast and re powder coat some parts. Do the 105k mile timing belt service before I start putting his engine back together.

Alright Fox. Glad to see you have a motor to begin working on. Now the run will begin...along with the "spending money" part of it.
You know, now that you've got your motor now, you have to do a "How many bottles does it take to blow a j32a2 PART 2" right? It's a mandatory thing here on Azine (new rule!). I have a bunch of full bottles laying around to contribute...

Looks good. I think I'm goig to do somethig similar. Get an mdx engine then hae the heads ported and polished. Maybe swap cams out for 07-08 tl s cams if ican get them to fit in that engine. Then bolt up all the stuff I have now. If you don't mid me asking how much did you get the engine for and what's te mileage it had on it.

Honestly it shouldn't cost much at all. I decided not to do any head work to the J35A3 to avoid having to wait/buy new head gaskets/bolts, wait for the head work to get done. I just want to drop it right in. I basically want it to have full bolt on's since at the end of the day I'm still going to be spraying the piss out of it and no sense risking messing up a set of worked heads.
Once the J32A2 is out I can have the cams sent out to gude performance. Be able to bring the longblock to my friends shop to build the custom long tube headers and intake manifold while it's on the engine stand. Plumb the direct port kit once the manifold is built. I'll order the supertech valve springs and retainers and that's pretty much it as far as the engine. Not looking to waste any money on the shortblock.

But that will mean I'll have to run a whole different exhaust set up and the bell housing will be different. Sorry I'm not a genius like you I can't just make stuff that should have never worked work lol. I think it would be easier to get a engine that will allow all my mods to mount up and have the correct bell housing and make spacers for different cams. Plus I'm going to port and polish the heads as well.

Plus of all the blocks you can use (for the setup you want) the J35A3 is the best as it is the same as the J32A2 which has the best cylinders. Any of the cams will require the shim, OR you can get a set of aftermarket regrinds as well.

Thanks Iforgot about that part as well. I think I'm going to use the 07-08 tls cams and see how that works. It will give me more power for about half to a third of the cost of regrinds.

I misunderstood the intent of your post a few back. You were asking if the TL-S cams needed spacers to run in the 1st gen mdx heads. I was naming off engine codes that wouldnt require the spacer BUT you were sa. My bad and sorry for the confusion.
And fsttyms1 is right, purchasing the j35a3 (240hp) is the best 1st gen 3.5 that has very few differences from the most important aspects of a j32a2 (260hp). There's a night and day difference in torque between these two motors (j35a3 vs j32a2). Mechanically, the cam in the 3.5 is almost the exact same as the 3.2. The ONLY difference (in regards to lift) is on the exhaust lobe- the 3.5 measures 36.326mm and the 3.2 36.389mm. The actual duration of either is unknown therefore could be different...and more than likely, they are. The heads are the exact same part numbers as are the fuel injectors which means they are identical in regards of their power capabilities. Yet, the j32a2 produces some 20hp less. Why? The j35a3 does not have the dual stage intake system like the j32a2. Thats worth an estimated 5-10hp. But the biggest difference comes from the tune of the ECM itself. The j35a3 is easily capable of producing atleast 20hp over the 3.2 but was detuned and purposed for torque. By swapping the intake system, running the j32a2 ecm and using j32a2 (or in your case j35a8) cams, you can easily make a big jump in power. Keep in mind that the hp figures given above for both engines are NOT sae corrected. But it gives you a good base to judge from since they are both not corrected. If I were to guess, I'd say maybe in the neighborhood of 275hp+/- 5hp (sae corrected).

Thanks with a full port and polish, different cams, and all the mods plus the last few I have to finish up before gettig the new engine ; I'm going to shoot for 275-300 at the wheels. Well see if that possible, 1foxbody got to 280 with a j32 with bolt ons. The thing that will be the most tricky is getting a throttle body set up that will allow me to maintain cruise control. According to fsttyms1 it's possible you just have to get creative.

Just dd the 105k miles service 20-25 miles ago so trying to get some time out of this motor. I search every couple of days trying to find one with the right mileage for the right price and nothing has jumped out yet to make me want to buy right than. Also I'm trying to finish up my intake manifold swap and finish my exhaust before I get the new engine. Once I get the new engine I'm going to start tearing the heads off to be ported and polished and new cams to go inside. Then go the 105k mile service.

As far as waiting for the right price, the 1st gen Acura j motors are going a dime-a-dozen right now. I bought a j32a2 today for $225 and the last one I bought for $180 if I remember correctly. Call the salvage yards and they will tell you why: the motors are diehard and hardly ever fail. Therefore, there is an extremely low demand for them. The only reason these are being sold right now is for swaps and projects, lol! Maybe 2% of used j-series sales can be brought by engine failures. The other 98% is just us dudes blowing sh*t up with too much nitrous (ME!) and too much boost (HOPEFULLY ME AGAIN!).
