In regards to oil consumption, it is indeed a serious issue on the J37A's. To my knowledge Acura has never released a TSB or any other kind of acknowledging statement; people who are under still under warranty at the time the consumption is discovered are having their short-blocks replaced with identical short-blocks, only for the problem to resurface. The thread below documents an owner who is now on his 3rd replacement motor and still having consumption issues.

https://acurazine.com/forums/fourth-generation-tl-2009-2014-123/acuras-response-excessive-oil-consumption-939258/

There is a solution to the consumption, but it involves altering the oil blend and running boost, which is not feasible for most people.


run boost on a j37 i heard it's not good. Havent tried it so i wouldnt know personally. But guys, just because it isn't posted on forums doesnt mean it cant be done. Ua7_rome on ig. Check out his tl type s 6speed. Hes got somewhere around the 325whp.

as for wtq. Im aiming for 300wtq. Anything is possible if you got the resources and knowledge.

Yes, I'm familiar. Jerome's (ua7_rome) highest ever number was 315whp. And he never posted a dyno chart, but I still believe him because he's been around TL's for awhile and has the full list of bolt-ons.

Others with FBO 6spd 3.5's have recorded similar (but slightly lower numbers). His is the highest I have seen to date.

The J37A4 is more of a stout engine in factory form than the J32A3 or J35A8 are (regardless of those customers cars which have oil burn issues due to a defective oil control ring design, which can be worked around in most scenarios or replaced under a new warranty extension TSB).

The common assumption that the J37A4 has "much weaker" cylinder liners due to being comprised of high silicone content aluminum instead of spun ductile iron liners isn't true for a street car operating under the limits of a stock jseries shortblock's internals anyways. The rods are actually quite stout as well, as I have proven then can hold 473wtq on premium gasoline consistently, even when daily driven and in harsh climates. The peak torque limit of those rods has yet to be seen, though as any good tuner will tell you: it is best to keep the maximum brake torque (MBT) at 5000rpm or just a couple hundred rpm higher than this by controlling total spark advance to keep the rods in good shape (not bent or broken in half). The dual VTEC has also done wonders for these cylinder heads, as seen in my dyno testing & results - especially when on e85 and more agresive spark advance can really show the engine's potential for power and torque after the VTEC crossover. It is amazing.

I have been daily driving my 2010 TL SH-AWD at 410whp for the past 2 years and have dyno's as high as 550whp on e85 and will eventually daily on ethanol once I have increased supply line diameter/capacity to deliver fuel flow. For each of the 3g and 4g TL platforms, I have many customers running these kits who, like me, find them to be quite reliable. Visit @gerzand on IG or my page "Gerzy Bear Performance" on facebook to see more info.

You're welcome. Yes, the SH-AWD system is a beast even when pushed like in the Rotrex application. Good luck in your endeavors.

If you check his build list, he states he is running the J32A2 heads with the 3 port exhaust. Most J series builders that are after serious power use this head as it flows more. How much more? Not sure to be honest. It's not a simple bolt on though.

i have a j35a3 with cl type s heads on my 03 acura cl type s 6speed. Just wondering how and if the 2nd gen type s heads would work better with the newer jseries short block. Ima check out it out now. God i would love to go boost.
