The J32A3 was rated at 270 HP in 2004 and it was revised latter to 258 HP. Did the new SAE way of mesuring HP affected the rating of J32A2s that are rated at 260 HP or not ?

This question has botherd me for too long, please clear my mind.

 

Im not sure, but I do know, a 02-03 Type-S is quicker than a 04+ base

 

yes. the j32a3 and the j32a2 have the same power output according to the SAE ratings. the j32a3 has a new code because of the cast manifold that is built into the heads. smaller things were changed like the characteristics of the heads but the overall assembly is the same

the j32a2 has 10.5:1 compression
the j32a3 has 11:1 compression so mods tend to yield higher gains.

however, the j32a2 with headers shows pretty big gains that the 32a3 will never show.

32a3 has drive by wire and the j32a2 is cable driven which is more sought after in boost application due to the ease of tuning.

if you want to run a j32a3 you MUST use a drive by wire ECU and those ecus check for everything under the hood down to the headlights so be prepared to spend more money thats unnneeded

 

no, because it was before the sae ratings ever went into affect, so more then likely 2004's and 2003's are rated the exact same way, as long as honda did not change there testing ways

not completely LMFAO, the pedal itself is still cable connected, which then goes to a sensor module (but the computer still has complete control though), but yeah i was like WTF when i first noticed it though yesterday

 

therefore its drive by wire

 

Thats exactly my point. When SAE rating come into effect, they told honda to revise their ratings. They said your engine that you claim at 270 HP is in reality pushing out 258 HP. I presume HMC tested their engines the same way in 2004+ that they did in 2003. So if Honda's initial testing were not accurate in mesuring power in 2004+ engines then it should have been the samething in 2003. Hence J32A2s should be rated at 248 HP according to new SAE system of calculation. Or maybe im missing something ?

 

not an exact science, but yeah something along those lines though

and part of the reason for doing that and such with coming out with the SAE ratings is too try and put everybody on a level playing field as far as power rating goes and such, because some manufactures where a little more liberal with the ratings and such then others, let alone adding that little bit of umpph to it while testing (such as feeding a little colder air to it)

 

sae was brought about to specify power output with all accessories connected

 

These are still measurements at the crank, right? Not at the wheels?

 

Correct!!!

 

one of the few things manufactures like to cheat a little on, but yeah it gives more realistic numbers that you will see on a regular basis, versus in test conditions
yes, x2, idk any manufacture that does wheel horsepower (or specifically states it)

 

^^ yeah that's wierd...

 

 

you can run a j32a3 with your A2 edu as long you switch over your CKP,CMP sensors & ,throttle body the ecu doesn't known the difference between the block as long its same firing rose you can run j30,32s,35s it's just like running a b18c Type r with a 92 obd1 non Vtec ecu yes vtec won't work and you'll have a low redline but the engine will run

 

but good info...BUT if you cant run vtec....why would you want to do that??? thats where we make power... and having a running engine is not cool if you cant make POWER

 

Best way to solve this is to put an 02-03 type s and a 04-08 base TL-P auto on a dyno and compare the HP output :p

 

No need Its a known fact a 2G TL-S will destroy a 3G TL-p it's the 3G TL-S that anihilates the 2G TL-S

 

Stock to stock maybe. Quick question.
Can I swap my j32a2 heads on j35 bottom end?

 

Yes, If you are referring to the 01-02 MDX J35A3?

 

Can a j37a2/a4 head be swapped onto a J32a2? It's in a CL-S 6 speed if that matters. If it is possible can anyone send me a link to some heads for sale please?
