All motor
Have you heard anything back from TBmotorworx? I know you have been busy with your turbo build, but I was just wondering.
Fsttyms1: Anything from Timkin?
I'm debating on getting my heads ported...

I have heard J32A3 heads flow the best (from factory), guess it is true LOL

J35zX heads 09+ TL 3.5, 08+ Accord 3.5, 10+ MDX 3.7 and a other Honda models. These fit standard 2-arm rocker style valvetrain as well as VCM variant motors for Honda. They ALL use the same part number. These heads are currently the best on the market but use different cams.

I have come to bless my fellow Azine members with the first pictures of the brand new 2014 RLX piston pictures. I do ALOT of R&D on oem Honda/Acura j-series parts so often times ill buy a random piece just for research purposes. As soon as I seen the new 2014 RLX parts catalog was released as well as parts ordering and access, I jumped on the previlege of seeing what goodies she (RLX) had in her.
After viewing the engine diagrams, I noticed that the piston was a much differnt design than any other j-series piston ever produced so I had to know more. Here's the deal, the new RLX j35 uses direct injection and this allows both higher compression ratios in conjunction with ultra-lean AF ratios....like AF ratios of up to 65.0:1. And no, that's not a typo!
The unique crown you see is actually designed to support combustion and due to this (and direct injection) it runs a 11.5:1 compression ratio. Before the RLX, the 4g TL 3.5 held the previous j35 record at 11.2:1...same as the 3.7 TL. Anywho, onto the pictures:
Also, a few comparison pictures of the RLX piston with a few others. From left to right: j32a2, j35 (RLX) and the j37a4
And you can see from the next few photos one detail that I really wanted to show. The top ring land is set much lower (6mm to be exact) than the others. This makes it an ideal candidate for FI and nitrous applications because it keeps the top ring away from the extreme heat.

Grrr. This needs to be updated some more, So what's with the sides of the RLX pistons, is that for ultra low friction? I wonder if these RLX pistons could be fitted to the j37a4 rods and crank. I think I have it figured out. There's a lot to this!

good eye dude....
about 7 years back, when I got the car and was naive as fawk, I took a rattle can to the manifold while on the car....I put some news papers around but as you can see, some connectors were painted in that process as well....
I need to replace some hoses and bring back the black LOL

And since I'm here, I'll drop these off:
And how about this, a standalone solution for those running 6mt 1st gen j-motors that don't want the hassle of immobilizers and/or emissions.

Anil, I've got nothing but love for ya but come see me next time you're in Dallas for them battery terminals and PCV setup! Lol. Other than that, looking good my friend.

I need to get a PCV setup...I have been eyeing something for a while
I might be in Dallas (well Richardson) in the next few weeks, I did text you the last time I was there but gonna send you a PM this go around...

The j-series marine blocks and cranks really peaked my interest in regards to their robustness in material and design. The block has approx 2.7mm of iron sleeve in the cylinders which is nearly 1mm more than the typical j-series engine. Sorry, the blocks will NOT work in a car.
Also, the crankshafts are forged with huge mass counterweights for excellent engine momentum at full power. Lastly, the 250hp engine is a 3.6L (yup!) that uses what we've already been using for years now: 89mm bore block with the 96mm 3.7 crank. Excellent combo for torque on the 89mm bore.I'm currently working on gaining more details for the engine management in the electrical aspect but it's very hopeful indeed.

Yeah, I've changed my cell provider (subsequently the number too) not by free choice but shoot me a PM and I'll give you my new number. Even if it isn't for your car, you need to swing by the shop and see what fun I've been having with the '10 MDX.
Yes, these are the parts from the 225/250 horse j-series marine motors. Thought the intake was a unique (something different) design. The electronics are based off of the j32a2 in regards to cam/crank sensors so that's a plus for those running the a2's with the 6mt's. They are not immobilized or emissions regulated (EVAP) which makes them ideal candidates for swaps but they are tuned for reliability and rich WOT runs. Remember, marine motors are considered severe duty motors so they are controlled differently than "road engines". Also, they are high torque motors. Recently Honda has introduced a new feature for ultra lean A/F ratios that create a "nitrous" style effect for power on demand. This is all done through the ECM of course.

No it will not. Bolt pattern is different. What's on your mind ThinJim?
I never found any wiring diagrams for that ECM but I'm quite certain there would be no major obstacles.
You know its funny you started looking into this. I have often wondered about this while sitting out on the boat relaxing in the sun having a drink after a day of playing in the water watching a boat on our lake with the 250 honda outboard on it. I figured it was controlled by a very basic ECU and have wondered if it could be used for swaps and to allow tuning?

Up on the marine ecm since it was the last question in the post. Though it would work, it's limited to 5k red line and has different bulkhead connectors which means it would need a marine harness to make work. Ive got diagrams if anyone is interested. Oh, and no immoblizer.
