WOW J37 TB spacer & p2r intake runners

Highspeed1 said:

Did the same recently too on my 2003 Accord V6 coupe. I have the DC Sports cold air intake first. Then I bought a used Acura RDX J37 80mm throttle body, a P2R TB adapter to attach it to an Acura TL J35 intake manifold. Then underneath it I installed the P2R 1 inch lower intake manifold spacer with thermal gaskets
(you should get it too). Then underneath the spacer I installed the P2R port/polished runners. I'm waiting for RV6 high flow pre-cats to come in. And then getting an RV6 jpipe in January 2023 because they said it would only be available then. Just with the mods above, the car does pull harder and faster. It comes alive from about 2K rpm, then starts to pull hard at 3K rpm all the way past VTEC at 4800K and beyond.

How do you like the p2r intake runners and intake manifold spacer? Right now I have my '04 V6 6-speed Accord coupe with the very very rare full hfp package one owner car it's my daily have a built 95 Civic Coupe with a k24 block and K20 head as my track car

Right now I have short ram intake instead of cold air because I live in Seattle likes to rain most of the year but I have a ram air duct that goes down where the driver side fog light used to be and runs a tube up to the short ram

Also have the rv6 V3 J pipe that deletes the third cat discontinued 2.5 OBX dual cat back exhaust and throttle body spacer

I've also gone through everything maintenance wise top to bottom front to back gasket seals belts hoses every piece of suspension spark plugs ignition coils I did just replace the front two pre-cats with OEM but would like to either do high flow pre-cats or precat deletes I'm thinking high flow because I would think they make almost the same horsepower? As the deletes?

That way that saves me from some of the rasp.

But I'm really stuck on whether to go with the easy j35 manifold that requires no modifications and a j37 throttle body or do the j37 intake manifold and j37 throttle body and then just do the intake air temperature sensor in the intake tube not sure if there's a big difference between the two manifolds power wise? But if there is I definitely want to go 37


And then lastly while I'm doing the manifold and throttle body upgrade I definitely want to do the intake manifold spacer and the ported and polish intake runners with those precat upgrades high flow or delete

And then save up get the Acura tlecu and then go get it Dino tuned here at either speed factory or Rich tuned

Then I'd be pretty much done with it since it's my daily and I think it would make a decent amount more power with those last few mods.

Would just like to hear your review on those runners spacer and manifold and throttle body swap without a tune and then I know once it is Dino tuned it will make even more of a difference

But so far I've already been able to beat 8th gen V6 Coupes with intake and exhaust and my neighbor's 9th gen with intake and exhaust he hasn't put on his J pipe yet or got it tuned and then I've also beaten 350Z de and HR and Challenger and charger RTS my neighbor's scat packs charger and Challenger mustangs and Camaros that make 4 to 500 even beat one of the older charger super Bee editions with ported heads cams headers full exhaust intake and tune almost every one of those V8 guys would ask if I'm turbo which is hilarious when they find out I'm just an all motor V6 and I don't even have full boltons yet

Always been in the two of The '90s Hondas Civic CRX is integras and s2000s but was never a fan of Honda Accords but something about the hfp package makes it look way more aggressive and these J series continue to surprise me


Sorry for the long comment would just really like to hear your review on those few mods because those are the next things I'm planning on buying and then would like to go get it tuned definitely know I'll be hurting some feelings with bigger v6s and v8s with those last few mods

Sorry for the late reply. I haven't been on the forum much lately. I love the P2R port and polished intake runners an 1" intake manifold spacer. I suggest you get them. I got mine new on eBay. Ah ok. I also have the RV6 high-flow precats. I suggest you gets if you haven't. Its not as noisy as their cat deletes, won't stink from exhaust and can pass CA visual vehicle smog check. The power/performance difference between the high flow ones and deletes are pretty small and negligible. I'm about to get the RV6 V3 Jpipe. Currently I don't have a third cat, I have a small glass pack muffler in its place, custom 2.5" cat back piping and 2 eBay N1/HKS hi-per style mufflers at the end. I suggest getting the J35 intake manifold, P2R throttle body adapter and J37 throttle body. The P2R TBA will let you bolt on that throttle body to the intake manifold. It's plug and play. All hoses and sensors will plug right in and the P2R TBA also acts as a throttle body spacer for a little more performance. From what I've researched online, a lot of people went with the J35 IM because they say it has better performance than the J37. But the difference is pretty negligible. The J35 IM with the J37 would be the easier option. Yes, the IM spacer and the lower intake runners are a good upgrade and bang for the buck. It will help your overall performance. I thought about getting the Acura ECU and tune, but it's too much work. Same, that's all I want to do performance wise. Because turbo kits aren't CA legal. Oh nice. Yeah, I loved the 94-01 Integras, but ended up getting a '98 Prelude. I put performance bolt ons on it too. Then now I have an Accord. I have an HFP kit on it too, but installed a 2012-15 Honda Civic SI OEM midwing because I wanted a higher spoiler than the AccordcOEM one. Yeah, the HFP kit is simple, clean and a little aggressive and sporty. And it blends well with the Accord body lines, just like Mugen aero kits. Sure, no prob. Good lucj and have fun with your build.
