What do you guys predict, do you think the J series line of motors will ever surpass the K series engine platform in N/A form for drag racing? Do you think the All Motor Street guys will all eventually make the move to the much larger J series? I only see these J series motors getting stronger and more powerful as honda continues to develop them, not to mention these motors are already making big power in the racing world and TB ~ Evans have only been developing parts for a few years! What will another 1-3 years bring for the J?

Do you guys think the J series will become the new supreme All Motor engine platform for the 1320?

yes i agree...old adage - no replacement for displacement.

93egSLEEPER

J series will be the new K series
K series will become the new B series
B series will become the new D series
The d series will just die.

H/F series... well they always just kind of stay in the same spot.

The J will only grow. People are just now finally realizing how cheap it is to do a jswap.

the one big thing holding people back is lack of camshaft selection due to the heads not being able to run a big cam right off the bat. I believe this has been addressed already though

soloDC

I wonder if honda will ever move to a DOHC design for the heads on their current J series. I believe the race guys have found out how to put much larger cams in the current SOHC J series heads tho. I have seen custom camshaft options for the J so they must have found a way to fit them, plus TB's integra sounded pretty mean at WCF even at idle.

It all depends on aftermarket support. J series has very little compared to other platforms.

TBH I really can't see many manufacturers getting onboard with the J platform, but I don't mind it being a novelty competitor in the all motor classes.

Sure there is no replacement for displacement but remember we are working with FWD here so there is a limit to torque that can be put to the ground off the line while staying within class rules.

IMO K series sounds better.

crazes

with time and platform development there will be faster and faster J's.

I think your forgetting that the turbo cars are producing way more tq then the all motor cars. So if they can put that power down to the ground then they will be able to do so as well.

bretx0r

Most EMS have some form of traction control available but turbo cars are able to work with boost by gear so torque figures are much lower off the line.

Sure J series will become more popular over the years and yes there are some quick ones out there but as far as being dominant over the K-series, I would say thats a bit overzealous.

unknown4now

x2 !! The J series won't be dominant due to not being so affordable & the install process compared to the k-series, b-series, etc. It takes alot more to do while the other are fairly more easy and affordable. Honestly the j series shouldn't be compared to the other swaps, its a 6cyl off the get. Much more power, displacement, etc compared to all other 4cyl motors. Its a class on its own. FYI, The b-series will never die. With more updated parts & technology, it just pushes them to another level. Got alot of 10-9 sec all motor b-series getting faster & faster. And lets not talk about Turbo SFWD class, the top 2 contenders are b-series. Just my opinion.

CTCD5

TB Motorworx went 9.89 all motor with a custom stroker kit in a 2200lbs DC, Evans tuning went 10.19 with a 3.2 liter all motor J. Both cars were at weight and fuel tested. So yeah, the J series will eventually pass the K series with more R&D

AllMtrRex

May have exaggerated a little...

Tippyman

You don't see alot of them now because they're so new, and there isn't really a niche for them in any popular class. It's a cool idea, but not one that has a place (yet.)

soloDC

Just my thoughts exactly. It took what 2 seasons for TB to get his J series into the 9s and yet there is still so much R&D to do on the V6. Since K series were allowed to run the upped 2.7L displacement it took them what 4-5 season to get a 9 sec time slip? And that 9 second time slip came first to one of the most well funded race teams in the import scene, I doubt TB has that type of backing... And let's be real, I definitely think the K series at 2.7L is reaching it's limits N/A, power is getting harder and harder to pull out of these 4 cylinders. If the J series had 7-8 years of race development behind it I think you could see it making close to 500 Whp all motor and a lot more torque. The domestics are only getting faster by the way at WCF, I think with time and development the V6 could move the game on.

The J series engines have huge potential, like any of the other popular modded honda engines development time is needed. We were able to make a bit over 400 whp / 320 tq with our first go at the engine this past season. That was with stock sleeves, stock crank (J37), stock valves, trans, etc and VP racing C85 fuel. We used tons of OEM honda parts in our build. The biggest hurdle with the J is the cam/head set-up as its not just a drop in and go deal. We ran a OEM reground cam set up on our engine, which limited us on lift/duration potential and ultimately limited our high rpm potential (our peak power was at 8,000 rpm but shifting at 9,400 rpm). We are working on a billet cam set-up with more lift/duration at the moment, which should really wake the engine up. The J transmissions are very strong, comparable to a b series if not stronger. That is probably one of the most appealing things in a racing scenario. K series are great, but you are going to be doing a dog box right off the bat to competitively race.

I can say 500 whp+ is very possible on the J series and will be done. We were making 113 hp/liter, which is what a stock K20 with bolt ons/tune makes or a mild built b18c with cams/tune makes. Something to think about in terms of what is possible.

Inline Pro already has a bunch of engine hard parts available for the J series (rods, pistons, manual tensioner, cams, etc) as well as head packages. Mounts, axles, clutches (twins), PNP EMS system, etc are all available. While building a J series is not as easy as a d/b/h/k, cost is VERY reasonable to race one at a competitive level. Our engine program has been dead reliable as well (only changing oil/filter between races and basic inspection). We are pretty excited for the 2015 season for J series development, hopefully more people will be building/racing them.

TracerAcer2.2L

The Kakimoto NSX makes 400whp N/A, but that was a track set up. Now, I know the C and J are two different motors, but they are both Honda V6's and have some similarities. So I can see a J meant for all out drag racing possibly reaching 500whp too

SwappedTURBOegg

this thread makes me want to run a j series in my s2k instead of the k24 i had planned.the 3.7L would make getting on the converter in boost so much easier. whats holding it back as far as drop in cams?how strong are the sleeves? 1k on stock sleeves going to be possible?

reading this I might have to rush to the junkyard at my earliest chance, 2 Honda odysseys with complete engines sitting there to start my collection.

JayWest

good to know
the tranny has always been the biggest deterrent to going k series for me. If j trannys can hold the power, thats definitely a route i would consider going in the future

DDTECH

We are in the process of Sourcing Cores for J series Camshafts.

Once these are found, then we can start producing and testing, Profiles that will work. The J series is a very, very nice base, but very limited right now on support.

boosted hybrid

There is a forum member here from MD that has a turbo J series that competes in true street class at MIR, he is on a stock J35 with upgraded springs/retainers (stock bottom end, heads, cams, etc) and is making into the 700 whp range. I think 900-1000 whp is possible on the stock sleeves, they are a fairly good design.

The best part about the trans is that you can purchase a brand new 03-06' Accord 6 spd from Honda for around $2200.00, its a steal! The TL LSD can be purchased for around $900.00 from Acura.

When you start looking at how cheap the J series engines are to purchase (J32s for $300-400.00 on ebay), and how cheap new OEM honda parts are for them its a no brainer. Headgaskets are $38.00 a piece, shifter cables $110.00, timing belts $45.00, etc, etc. Even the J37 cranks from the MDX are $410.00!

nonvtecallmotor

Steve went 9.5@155 at WCF with his stock J. Steve also told me that the only thing that he broke in the trans was 4th after alot of abuse.

Flexer

Once companies start offering some parts for the J series and swaps start hitting the tracks people are going to start going to J swaps in herds. Look at the example above. Guy made 722 whp on 22 psi on a $580 dollar borg warner S366. Motor is totally stock. Does it get more budget than that, and he put it in the 9's.

People are slowly coming around and some of these aftermarket companies are going to step up and start making parts and that will be tipping point that gets the j swap moving.

Pro-SeriesFab

Hard for me to really see it as replacing the K . . . adding 2 more cylinders seems like a cheap way out as far as "replacing" a motor.

Might as well add 2 more cylinders with a junkyard 5.3/4.8 LS motor for $500 out of a wrecked GM hunk and throw a $200 ebay turbo and make 1000rwhp like everyone else out there if the plan is ultra cheap power.

I still don't really see the K vs J being an apples to apples comparison.

I guess it can always live on in the mini sprint/circle track and scca classes of the world.

soloDC

But it is apples to apples, the J series is allowed to compete right next to the K series in All Motor Street form with a slight weight penalty, it's also allowed to compete in true street and SFWD I believe? It's also a honda motor. People above were just giving examples of how stout and sturdy all of the J series components seem to be. Any motors that compete against each other should be up to a direct comparison.

Now as far as the J series taking over the K series in popularity and on the street is still to be seen. I do remember a time when ppl thought the K series would never be more popular or as common as the B series because of cost, lack of development and not enough aftermarket support for swaps. This all changed of course, the K series became a huge hit!

Pippen_001

The big advantage of the K series is the angles of the valves, which gives you the possibility to run big cams.. How about the J series? Just wondering...

Like Jaywest said, my decision to H2B was the weak K series gearbox. I would just skip the K and go with the J in the future.
