If you have the stock CBE, I think a cutout is a good option. Sonnick got my ass wanting to do it
Hard to believe. So, it'd be more worth it to save this J37 top end I just got, and wait until I can afford doing the bottom end, as well?I don't feel head work is worth the effort. My J37 heads did yield high end for me (back on J30 and can feel the difference), but it's negligible unless your high HP N/A build.
You may see better gains being a J35 to J37 heads, where I was J37 heads on a J30.
i have a 87mm bore mounted to a 89mm head. Can't didn't blow up, but it did create a mushroom effect and slightly dropped the CR. wished I just did straight camshaft instead of going through all the trouble of swapping the head.Hard to believe. So, it'd be more worth it to save this J37 top end I just got, and wait until I can afford doing the bottom end, as well?
I assume mounting an 89mm short block to 90mm heads wouldn't be possible without boring anyways, or it'd be fine?
Guess I'll just use the manifold and throttle body from it, for now, and wrap these two heads up in my garage ;(
Is this thread still alive? If it is, i have a 99 Odyssey with a J35A. Lowest HP J35 alive. Wanting to see what heads work best on this. Was wanting to swap in a J35A6 from the 2005 Odyssey but would need new ECU and wiring harness to make it compatible. Seeing as my engine only makes 210hp and 220tq I need some serious help to get it close to what the other J series engines get. Would J37 heads and intake be best or swap in an A4 from a 2002-2004 odyssey THEN head swap it? Funds aren't an issue as this is my project car for fun. Just need to know the best rout to go! Thanks for any and all help!
