Hey guys, putting this out as a feeler for interest. As some know, I've started building a v6 2000 prelude. Currently bolted in the car is a j35a3 engine with unknown mileage. I also have apart orig j32a2 block and heads from my old cls6. Current plan is to tear down the j35a3 and rebuild it with oversized high compression pistons, rings and bearings (on order) Undecided on whether to run CLS or RL cams (on hand). Other minor mod will be a j37 intake (on hand) and b series tb. So question at hand is would anyone be interested in seeing this documented as a rebuild thread?

If the documentation process (pictures / text explanations et al) does not become overly burdensome, after your diligent work in the garage, then I say (vote) ,
There is always room for an accurate / concise reservoir of data and findings when accomplishing such an undertaking.
In addition, for as long as it lasts, your v6 2000 prelude build effort will make this place less of a .
Hmmm, not much interest. Well, I will at least share that the pistons I will be running are estimated to yield 12.1:1 compression. Which is roughly equivalent to the CR of a CL type S engine on 3psi of boost. That's not even considering the additional displacement from j35 crank and oversized pistons.
Anyways, although P2R sells the pistons, they can be obtained much cheaper if one should know the part # and where to look (which I do).
Alright, up to 3 votes. Whoo, lol.
I'll at least indulge you few enthusiests with some updates.
1) Timing components and cyl heads removed from j35a3. Typical grime of 20+ yr old engine
2) Disassembled and itemized valvetrain components (springs, retainers, rockers and pins). Pictured in bags are actually RL valvesprings
3)Cleaned j32a2 heads, valves and j35a8 runners. Newer runners will facilitate RL injector upgrade. After cleaning
4) Priced and ordered few more parts. Ordered: Oil pump, clutch slave cyl, valvestem seals, cam seals. Shipped: Pistons and rings. Not shipped: Bearings.
Next on the agenda is lapping the valves, pulling the J35a3 block from the car and getting it onto the engine stand. Next, tear down to bare block. Then drop off at local machine shop to clean, bore & hone cyls to 89.5mm. Also, check for deck flatness and machine if necessary.
Yeah, I'm in for it.
I've never done a J-series (mostly SBFs) and probably won't ever go deeper than intake/valve covers/timing belt any more at my age.
But the hotrodder in me says I might learn something, so do it!

Thanks, this one is intended to be somewhat of a mild build. Not a muscle car guy, but I've done bare block up j series builds with my 6th and 8th gen accords. The 8th gen is a 3.6L with 2011 RL heads, dual vtec cams, pre-cat deletes, j-pipe and ktuner. The 6th gen is a 3.5L with ported heads, BC cams, headers, 3.55 final drive, stage 4 clutch and flex fuel on AEM standalone. Both can be found on Azine and youtube.
I see you are using an accord 6MT, is that the one you were reconfiguring with CL-S6 internals / LSD or am I thinking of something else?
I imagine you had a fun time with the 'I spy' books at one point in your life. Perhaps I should start leaving some 'eastereggs' in the background of the pics I take specifically for you.

Situational awareness, it's always on.

Hey Zeta,
Actually this one is from an 05 TL. At least that's what it came back as when inputting the VIN on Acurapartswarehouse:
The other trans that I swapped final drive and added a 3G TL LSD to was from my 8th gen accord. It had a damaged 1st- 2nd gear synchro set when I got it. Plus I wanted the 3.55 fd for the 6th gen. So, I moved some parts around and replaced what was damaged.

Speaking of the 3.55 fd, now that you have had a chance to use it, what are your impressions & have you found advantages / disadvantages that come to mind?
Generally speaking, if I understand one advantage of the 3.55 fd (for the likes of Street/Strip & autocross folks) is it gets you up and going quicker from the hole shot (like 1st thru 3rd gear); however, one loses top end mph while running higher rpms?

As you mentioned a benefit is a slightly quicker rpm ramp up, i.e. from a dead stop to get the car going faster. Also, when shifting gears it seems easier to keep the revs in vtec powerband. Which ultimately keeps the momentum more consistent.
As for disadvantages, torque steer and wheel spin is slightly more prevalent on hard launch. As a result traction becomes more important (this plays into why I run wide, 200 tw tires).
I'm sure there is some reduction to the vehicle's top speed,. But, there hasn't been any noticeable detriment in reaching speeds up to 100.
Lastly, with the 3.285 f.d, the speedometer was innacurate and would worsen with higher speeds. I attribute this to running taller wider front tires (255/40/17) vs the CLS oem (215/50/17). Surprisingly, the 3.55 fd ended up fixing that.
I imagine you had a fun time with the 'I spy' books at one point in your life. Perhaps I should start leaving some 'eastereggs' in the background of the pics I take specifically for you.
Still to be ordered: head gaskets, head bolts, valve cover gaskets, lower engine gasket kit, thermostat, lower intake gaskets, P2R manual timing tensioner, j37 throttle body adapter, j37 plenum and tb gaskets. Probably forgetting more, but you all get the idea.
As for what's next on the agenda, valve stem seals showed up today. So, likely will start re-assembly on the heads. Planning to use RL (j35a8) intake & exh valvesprings, CLS rockers and likely CLS cams (for now). I do have a set of RL cams laying around... But, sadly I sold my spare set of cam spacers a while back to someone I refer to as the RL reaper. Hmmm, wonder who that was?

Is he the one who frequently haunts local salvage yards in Nashville, TN in a hoodie wearing multi-pocketed parachute pants?
So quick update, oil pump and a few gaskets/seals have arrived. Also, dropped off j35 engine block and j32a2 heads at a machine shop today. I asked them to bore and hone the cyls for oversized pistons, resurface the heads and check the block deck surfaces for straightness. Depending on how the block specs out, it may need to be resurfaced as well. Resurfacing reduces the combustion chamber size. Thus, when reassembling one should use thicker head gaskets to make up the difference. That said, I'll need to know how much material is removed before ordering new gaskets.
Lastly, the machine shop was a bit backlogged, so it may be a few weeks to get everything back. In the interim, I'll likely work on the conversion wiring. It may also be a good time to open the TL transmission for an inspection.
Well, I do have P2R's ported heads and ported lower intake runners on my j35 6GA and honestly I'm not sure it was worth the money for NA. This one is not as serious of a build, so I may just gasket match the heads and runners.
IMO a better investment will be headers, high flow cat, 3" catback, j37 intake and a 74 or 76mm throttle body. Which is basically what I have on my 6GA. The 6GA made 289whp/260 tq on pump 91, which was less than expected. My only explanation is that timing was limited by the low octane and the non-high flow cat was restricting flow.
Well, discovered something interesting today. It seems the cyl heads have a small recessed area on the intake side, which is larger than the opening on the runners.
P8E head intake port
Oddly the runners do not have the matching recessed area, as evident by the exposed metal showing thru the gasket. PGE runners
For comparison, I also checked a j35a8 head. Which did not have the recess on the head nor the runners. j35a8 cyl head intake port
j35a8 runners
So that said, to optimize the flow it seems that the runners should be port matched to the cyl head.
Happy Friday All,
Small update, yesterday finally picked up the block and heads from local machine shop. Block is now prepped for 89.5mm pistons, no deck resurfacing was needed. Heads were washed and resurfaced, 004" removed. Going with slightly thicker (.036") Cometic head gaskets.
Few pics:
Next on agenda, reassemble heads. Block reassembly will be pending arrival of more gaskets, seals, bearings, etc.
Hey guys, dropping in for an update... Finished port matching the heads yesterday. By no means is this a professional job, But, pretty happy with the results.
exh side intake side lwr runner to cyl head
Now onto today's progress. Started off by installing RL valve springs into j32 heads.
front head valve springs installed
Also installed coil style lmas courtesy of @Thefireball
Next, re-installed cams, rockers and rocker shafts. rockers and cams installed
For gee whiz reference, vtec can be locked to always on (aka vtec killer) by swapping rocker pin positions: top rocker set normal configuration. lower set, locked vtec configuration left set, vtec rocker arm locked. right set, normal configuration
Alternatively one can also utilize aluminum rockers from other j series, such as accord hybrid & some odysseys. However. that setup requires quite a few more part changes.
In any case, I'm not planning to lock vtec on this one.
As for what's next on the agenda, likely next weekend I'll start measuring, and filing the piston rings. Then installing new pistons on j35a3 rods, in preparation for reassembly.
Also planning to clean up and paint a magnesium rear valve cover & j35a3 front valve cover. The objective is to eliminate the rear pcv valve & front breather hose in favor of two breather filters. Lastly, plan to cover the egr port with a flat piece of metal. Actual egr blockoff plates have gotten expensive and hard to find.

Would the OEM EGR plate from the Honda Civic & Element work?
Maybe the RL reaper can snatch one if he is out roaming the salvage yards?

Hey Zeta. Yes, that oem part should work. I even tried ordering it from Honda and Acura. Unfortunately, both orders were canx due to part being discontinued. I also thought about checking a local pick a part, but my area doesn't get many late model Hondas or Acuras.
In anycase, its not very difficult to make a blockoff cover. I made one recently for the h23 del sol, using the j35a3 water pipe and egr gasket as a template. Not pretty, but it works:

There are four Elements at one of the local pick & pay's proximate to my location.
Maybe I'll go check them out this week if the the weather permits, rainy cold front moving through today.
Will update when possible.

Thanks Zeta. No worries. I just checked the inventory at the local yard and it seems there is a 2010 tsx 2.4L that recently arrived. I may go check it out this week. There's also a 07 MDX there that I had pulled some parts from. If it's still there, kinda wanted to get the block for future use.
Hey guys, checking in with few updates and part delays...
The good: P2R manual timing tensioner and Cometic head gaskets arrived. Also, 2x Rockauto shipments arrived, containing several gaskets, head bolts, spark plugs and a shorter serpentine belt for AC delete.
Now for the bad: A third Rockauto shipment may be lost, containing more gaskets, timing idler, serp belt tensioner and thermostat. Additionally, although King main bearings are in stock, the rod bearings are still on backorder.
So, while waiting for parts decided to visit a local junkyard today. Ended up removing a j37a1 block from an 07 mdx. Long story short it was a huge p.i.ta. Originally I was just going to get the crank and rods. But, it ended up being cheaper to get the whole block... So, now I'm contemplating what to do with it. Maybe dig out the j35a8 block that I stole the j35 crank from and Frankenstein another j36?
Lastly, since I spent so much time with the j37 removal, didn't get a chance to look for an egr blockoff plate. That and @Thefireball asked for a part off a 2G TL. I didn't forget, I was just tired!

Speak of the devil!
I picked one on the 13th and going to another yard today to check out one Element and a possible civic si for two more.
I'll send you one to 85614 as a personal donation for all of the excellent projects shared on here.
Waiting on some 4X6 ebay plastic mailers to arrive.
If I'm lucky today, going to put the other two up in the BM.
Interesting observation though, out of the four Elements present with engines on the 13th, two had already been 'picked' & I harvested the last one, so apparently these things are popular.
I'm surprised at how stout they are made, nice thick aluminum.
