Hello to you all!
Can you give an advise?
I'd like to use J35A8 block from Acura RL with normal head (3 manifold exhaust) J32A2 or J35A4.
Which kind of heads should I use?
The main question is in the oil and coolant channels.You can use either one. You can also use the heads from a J35A3 if you need to.
Which ever head you choose, they will all need the same amount of modifications to work. I know it can be done, but don't know the specifics.
The main question is in the oil and coolant channels.
Does it fit to each other?
Thank you for replay.No sir, the oil and coolant channels will not match up.
You need to modifiy those to make either of those heads work on a J35A8, and there is likely some other stuff too. I only know of 1 individual who has done it, but it can be done.
Gerzand on Acurazine.com has done it.
The J35A4 in the '02-04 Odyssey uses FRM sleeves, and I've heard it's not a good idea to run forged pistons in them. So, are the '05 RL pistons forged? What OEM 89mm pistons would be suitable to use in the FRM sleeved J35A4 block? I plan to use the J37A1 heads, I believe the intake valves are 36mm. Is there any other reason why I couldn't run the J35A4 block with J37A1 crank/rods and heads?Option 1
With '01-02 complete MDX block or '02-04 Odyssey complete block (crank/rods/pistons) it is required to purchase 2005 Acura RL pistons (new set $50 each) This is a best option still since these pistons have clearance for large 36mm J32A2 (intake) valves thus no modification needed. Despite the fact they have higher 11.0:1 CR still even supercharger can be used here with low boost up to 7psi intercooled (assuming safe AFR). In addition, if 11:1 CR is too high for you, you can use '03 CL-S pistons with 10.5:1 CR.
Note: Odyssey pistons do not have clearance to fit large 36mm J32A2 (intake) valves. Solution - custom job to increase valve pockets.
BTW, The only advantage to get J32A2 block is due to better cylinder sleeves to withstand heat designed for higher redline vehicle, otherwise depending on the price Odyssey or MDX block are the best bet.

No sir. They are castSo, are the '05 RL pistons forged?
J32A2 pistons from an 03 Cl-sWhat OEM 89mm pistons would be suitable to use in the FRM sleeved J35A4 block?
I'm pretty sure, that is going to require some modification.I plan to use the J37A1 heads, I believe the intake valves are 36mm. Is there any other reason why I couldn't run the J35A4 block with J37A1 crank/rods and heads?
I have j30a4 and want buy only j32a2 block and heads. And use it with j37 crank to build j36 enjine.No.
Different sensors, heads (including most of the valve train, if not all of it), crankshaft, Throttle Body...maybe some other stuff also.

And i want to know. j32a2 block and j32a3 are the same or not. beacause in Russia i cant find j32a3 block only j32a2
Ok) I understand. Thank you)If you are using a 03 or later Accord, then I don't know if the J32A2 block will line up with the engine mounts in your 7th gen Accord.
I think you could get the J36 (Stroked J32A2) working in your 7th gen Accord, but the wiring/re-pinning may be a pain in the ass.
