I was just talkin to a guys I know that owns a performance shop, and he said that he can bore and stroke my engine and do a little more tweaks to it and it will be around 3.6 liter. So im thinkin about takin up his offer...

 

Dude. Weren't you just saying there's something wrong with the car?

Sorry to jump on your threads but after all, I am a post whore.

 

no need to bore stroke is all it takes

 

Here we go.

 

i am already on 260 hps i dont need it faster.. I just need to get the weight reduction..

 

LIES! I tell you LIES! I got headers and Intake is coming next spring (when it gets warmer)

 

how much is the average you would look to spend on the 3.5 and is it worth it?

 

Thats a question CleanCL could answer he has the beast 3.5 engine.

 

 

why would you spend all that money to bore the cylinders which requires custom pistons, this is not an easy task. there are a lot of measurements and variances and calculations. before i go any further, my advice is to just buy OEM rods/crank which will achieve a 3.5L conversion and will utilize your stock pistons. absolutely no need to touch anything else aside from bearings/gaskets.

for those looking to go past the 3.5, start with the 3.7L mdx motor.
3.5L bore/stroke: 3.5 in x 3.66 in (89mm x 93 mm)
3.7L bore/stroke: 3.4 x 3.8 inches (90 x 96 mm)

keep in mind the cl-s block can only be bored out so much, regardless custom pistons are in order to achieve anything above 3.5. and the stroke... well theres nothing you can do about the stroke except swap blocks. i'm pretty sure the 3.7 stroke would never clear our heads.

 

i dont think it would clear the heads either. what would the compression ratio be?

 

over 11.0:1, probably closer to 11.25:1 in our block

 

What are we looking at in terms of HP it I were to do this with my CLS?? Also whats the cost associated with this conversion?

 

id say 270whp/240tq at the minimum for roughly $4,000-5,000, i still need to get a dyno, but i think the gains are even higher than that.

 

It should be

 

Yeah.. But you're not him. This about the original poster (LH's old car. )

 

yea i was just sayin

 

WHen you say OEM rods/crank you mean RL rods/crank. Is that all i need for the conversion? I mean if we break it down. than
1) I go to the mechanic with the OEM RL Rods/crank
2) He Takes out the engine and replace the Rods/Crank
3)He puts the engine back in and we good to go???
LOL, damn im such a no0b. Please explain

 

its not something you just unbolt and bolt back in. Its a motor rebuild (if you want it done right)

And you revived a year old thread

 

search my name and 'typeR'

that will tell you everything you need in order to achieve a 3.5L motor

 

I don't think the crank's from 04+ engine's fit in the 03 and earlier engine's. I know for sure 04+ , all the engines are basically the same. You can take a TL 3.2 liter, and put the MDX 3.7 Liter crank in there. If you look at the Honda part numbers. The 3.7 liter and 3.2 liter use the same timing belt, and the deck height between the two motors is the same, including the 3.5 liter motor.

Also the snout on the 03 and earlier cranks are a lil different. That is why I am not sure that the newer cranks fit in the older motors.
Just incase you guys are wondering how I know any of this. I am with P2R in South Florida. We do alot of J series stuff. Here is a picture of my 91 Civic with 2005 Accord J30 6 speed.



Lil start up video from long ago. I don't have any videos of it running online.

holy crap the engine is sticking out like crazy!

 

I'm in Miami.....where is p2r ?

 

the only cranks that will fit the j32a2 (01-03CL-S, 02-03TL-S) are the 03-04 odyssey and 01-02 mdx, don't quote me on those years, but they are in the generally vicinity. the later 3.5 mdx will not work, so AGAIN as i have said in another thread, the 3.7L will not fit, not to mention you will NOT gain 3.7L by putting in the 3.7 crank/rods because the new mdx also has a larger bore.

 

its 02 oddey pretty sure the 03 wont work and not sure on the 01...but 02 is what i had

 

We are in Ft.Lauderdale
