Does any one here have the specs on the Camshafts for the 07' Acura MDX? Searched but no results only some for the j35.

Im in the process of an all motor build and my next step is cam work, before purchasing a custom set and spending a quite a bit of money, I want to know if anyone has an educated idea of what type of gains if any is worth the small price for oem mdx camshafts? Im almost certain they will fit but again I need someones expertise, and experience.

I can pick up a set of em' for 144.72 a piece. Im thinking coming from a motor thats putting out 300hp and 275 ftlbs may have some benefit for the j32a2.

they won't fit.

Maybe the crank shaft will.

CleanCL

no.

i would like to know why the cams wont fit??

rock arm issues? valve lift to high?

I am under the understanding that they will, however i only see torque being gained from them. Also what pistons etc and compression ratio will you be going for?????

CleanCL

iTrader: (4)

it has nothing to do with that... the cam/crank LENGTH physically does not match with the cl-s crank/cam length. this has been discussed in detail, please search.

I searched and found nothing only info on the j35.... Do you know what makes them longer? Do you happen to have the specs of em'?

CleanCL

iTrader: (4)

i believe they are shorter and not longer. the newer motors are all using the shorter length parts, the accord 3.0L, TL 3.2L/3.5L, RL 3.5L, so i would put money on it that i'm 99% sure they will not fit.

All I know about the 07 Camshaft is that they were hollowed out for weight reduction.

why not just swap the MDX 3.7 engine?

CleanCL

iTrader: (4)

i wonder if the 6spd TL-S tranny would mount to it? screw it... AWD CL-S

iTrader: (2)

do it! you wont...

that would be so freakin bad.

If I could get one, how much do you think it would run? not figuring labor.

CleanCL

iTrader: (4)

how exactly would you install it into the cl-s?

btw...

brand new 3.7 shortblock from acura w/ Block, Pistons, Rings, Rods, Bearings & Crankshaf
$1213

each head is about $330 a piece

^ i saw that also... btw can you run 3.7 shortblock with cls heads? or even 3.7 internals?


basically i'm asking if J37 swap is possible.

all these swaps are sounding real crazy but in a good way

rondog

iTrader: (1)

AWD CL is sounding crazy, that is all I would ever need, oh, and a stronger clutch.

CleanCL

iTrader: (4)

just swapping the 3.7 shortblock into your CL will not work.

oh and since acura has not mated a 6spd to any of their AWD platforms, chances are you would have to run an auto...

typeR

slightly off subject ...


the Honda Accord Coupe HF-S Concept represents a radical vision for customizing the all-new Accord's design and performance through stylish and functional modifications. A dual-port exhaust system can provide additional performance when needed while retaining low noise output during relaxed driving sound like anything fimilar? cough RL dual flow pipe i was trying to talk u into cough... not done any research but id say a re sleve to a larger bore and the '02 mdx/oddey crank/rod swap could yeild the desired 3.7 output just use the 07 mdx pistons

CleanCL

iTrader: (4)

hahahah still trying to get me w/ that exhaust...

when we had the motor apart last year, the cylinder walls looked too thin to bore much more, it would be very close. also the oil cooling becomes an issue. i have a feeling the internal block design is different on the 3.7L.

NEVERSUMMER

Wasnt GM#2 saying something about a NSX swap. Wonder how difficult that would be.

NEVERSUMMER

I was just looking on ebay and you can get a complete J35 MDX motor, ecu, everything you need etc. for under 2 grand. It looks like it would just slip right in, but we all know it wouldnt be that easy.

typeR

which year ? u wouldnt want the ecu or the heads

NEVERSUMMER

I saw a 2004 motor for that price. And an 06'- 07' for $3500 or something like that.

engine mods by stroking seems to be the new thing. :})
3.2> 3.5 >even possibles 3.7 ??
FWD> RWD > AWD

great, i am pretty sure we will see more of this.

Hey type R, whats the average cost of going to 3.5 with the rl pistons

NightRider

The only reason to go with an 04 MDX engine is for better midrange with 3500rpm peak tq gain but no real hp gain. Why not go with an 05RL transplant for the same tq gain (albeit @higher rpm) and 300 hp top end? I don't recall if a hybrid 3.5 MDX bottom and RL top is possible, but that would be the closest thing to a complete 07 MDX transplant, which is easier said than done. As far as an NSX swap, that would probably be very difficult trying to put a mid mount longitudinally oriented C series engine in a CL.

where wud u get a nsx donor $$$$$$$$$

i never saw it that way.
what of the oddysey ?
Are we talking pistons or cams in the 04 MDX engine ??

CleanCL

iTrader: (4)

i dont think a 2004 mdx motor would work, i believe it has to be 01-03, but i'm not 100% on that.

NightRider

The J35 is 3.5 L obviously. Bore is 89 mm and stroke is 93 mm. Output was 210 hp for the J35A1 (99-01 Odd), 265 hp and 253 ft·lbf for the J35A3(03*-06 MDX), and 240 hp@ 5500 rpm and 242 ft·lbf@4500 rpm for the J35A4 (Oddyseus).

Basically, the Odyssey J35A4 (which is the 01&02 MDX engine) has different powerband characteristics and less specific output than the 03+ MDX J35A3. *Something changed in the 04-06MDX as hp and tq increased by 5 each, maybe better intake. So 04MDX block, pistons, etc. (what I call bottom)>Oddyssey block, pistons, etc.

If people didn't know, since the heads are so similar on the J30A1 (98-02 Accord/1G CL) and the J32A2 (01-03 CL/TLS), it is fairly easy and inexpensive to swap in J32A2 cams (COUGH, ATTN: 1G CL, 2G TLP's, COUGH). Although, you would think if this is the case then the heads would be similar enough to the new J35 to swap in the 300hp version cams into a CL/TLS...but if the shafts are shorter as previously stated then maybe not. Either way, I haven't yet heard otherwise that 04-06 MDX bottom and 05+ RL top is out of the question.

sinfulj32

hmmm... a little off topic but i was on av6 and saw that someone put the 07 tl-s cam into his accord j30 motor. sounds like a good upgrade due to the lightweight hollow cam and larger vtec cam lobes. if the j30 and our j32a2 heads are so similar then cant we just drop in 07 tl-s cams in????

NightRider

Good, that may just prove my hypothesis correct...

sinfulj32

^well then we may have something going....unless someone knows for sure that 3g tl cam wont fit.

CleanCL

where have you guys been? i've been saying that nothing of the newer 3.5s will fit into our motors.. seriously guys this has been discussed MULTIPLE times.

Allout

Here's the definitive thread on the RL cams.
http://www.acura-cl.com/forums/showt...highlight=cams

NightRider

Not looking around enough to read that thread obviously...I stated a couple posts back that if the camshafts are shorter then maybe not, but didn't have any confirmation either way at the time.

PowerRev

I have installed a set of 07 TL-S cams in a 04 J30 engine.
03-07 Accord
04-08 TL
07 MDX
All those are interchangable. They will not fit the 03 and earlier TL, CLs
