I am thinking about rebuilding my D16Z6 engine. The block has over 250,000 on it. Is it worth using the same block but replacing with new pistons, new bearings, and a new cam?

dohcdelsol

as long as you get the block cleaned out and blue printed, checked for cracks and cylinder wall wear, and all passes then you should have no problem re-using the block.

id recommend having the block milled. and if your willing to spend a nice chunk of change, id personally put all new internals in and do it right the first time so you dnt have to crack open the block down the road. new rods pistons bearings headstuds valves valve springs retainers and cam.

what is your funding available? how are your power goals compaired to reliablility? shooting for NA or Turbo app?

As long as the block itself is in decent shape, I will probably start to slowly buy new parts, than by summer take out the block and do the overhaul. And funding is not a problem. As for power gains to reliability, if I can get 150-160 out of the block, I`ll be happy. I don`t see myself racing the thing any times soon. I just need a little more oomph under my hood. And I`d much rather go NA for the time being, on less "expensive" piece that could possibly break lol.

Would it be worth rebuilding the tranny? or getting a new one? Cause I know before I remove the block, I need to drain the tranny and remove it. if I do that, the 15 years of crap that`s holding the tranny together may flow out with it, and it may not work again.

PardonmyEK9

Get a y8 tranny. you dont need to get forged internal until you have to ugrade the map sensor in my opinion. It wouldnt hurt to do it while it is apart though do it right the first time

What kind of price range am I looking at with a y8 tranny? And I shouldn`t have to upgrade the MAP sensor with the y8, would I? Sorry I`m askin dumb questions, I`m just going through a hard time right now and my head in a spin. Working on my car is keeping my mind off things.

"Upgrading the map sensor" he means going forced induction (turbo/super charger)

Makes sense. Is there really any difference between the z6 tranny and the y8 tranny? I know the z6 has aluminum forks and the y8 i think has steel forks.

Since I`m going to get a new tranny, what would be a good site to get one from?

dohcdelsol

the gearing is slightly different and you"ll have to re wire the vss. just keep the z6 trans. 150-160hp NA on a z6 is a bit challenging. itll be cheaper to swap for a b-series and less down time. ive already went down this road and rebuild my z6. took me 2-3 yrs to gather good internals and all. since your hands are goin to be on every little part i guarentee youll end up replacing everything. T-belt, h20 pump, tensioner, oil pan gasket, head gasket, valve cover gasket, painting covers, cleaning every little space. itll take some time and i recommend not just throwing it together.

i actually bought a z6 engine for like 150 bucks and took a gamble the block was ok. stripped it down. sent it out. had Dan FS Motorsports do the internals of the block and Dave at Headgames build the head. all in all ready for boost spend 5grand on everything including labor. awesome learning experience. but for that 5 grand i wish i spent it on a b-swap. would of been more reliable, less car down time, and id prolly still have the car.

dnt forget youll need certain tools, engine hoist, engine stand, something to get the bitch pin out of the shift linkage, big *** breaker bar to crack the crank pulley bolt, clutch alignment tool if you dnt get a new clutch kit, axle nuts are 32mm. i believe the flywheel bolts are like a 14mm 12 pt socket. if you get ARP headstuds there like a 12mm 12pt deep socket. and a good torque wrench.

just do your research before you buy anything. write a list of everything youll be buying. price it all out. then add a few hundred bucks for the unexpected. good luck.

I`ve been doing a bit of research today. And just by doing simple math, I figured getting a JDM D15 for $549 plus shipping, and a new z6 or y8 (still deciding). That it would be much cheaper. And rather than hoping and wishing that my block is in decent shape, I know I`ll be getting an engine that is in decent shape, plus if I wanted, I could always swap out one or two things rather than everything. So, rather than a $5000 rebuild, it would only cost me maybe 1500 lol. Unless of course I`m missing something.

vic631

i think your better off just buying another single itll be cheaper

I was thinking, what if I got another d16 from a junkyard, stripped it clean, than checked it? Than if the motor checks out, slowly get parts for it, than when I got it completed, put it in. Or is that just a dumb idea lol.

That's what I'm doing. I got a bare clock on the way and plan to replace everything on it for the turbo build I plan on this summer.

If I may, where did you get the block? Cause If I can get one not out of a yard, I would feel that much better when re-building the engine lol.

Ebay. You should try Craigslist.

I will whole heartedly agree with dohcdelsol on this one. Stick with the D16Z6 and stock tranny. I am doing this project right now with 208k on the motor and I will tell you, it is much easier to get my hands on a B18 than that darn D16. Albeit they are JDM's but at least accessible.

That block you're looking for, the D16.... I've got a few quotes from $750 all the way up to $1000 but ultimately I am just gonna’ drive it ‘til the wheels fall off.

The fun is in the build anyway, right? So why get the parts to rebuild what you've got (if what you’ve got will work), when you can get what you want and build up? Having the B18 on a stand in my garage just looks friggin' cool and I get all of the perks out of my investment rather than a bunch of parts laying around in boxes with their painfully expensive accompanying receipts.

The best part? I still drive my stocker D16 to go get those parts.... Yeah it's slow but, one day......

If your saying stay with my D16Z6, I should just build off of it? Your post just confused the crap outta me lol. I know what your saying about the having the engine sitting there waiting for that awesome day of putting it in, but you confused me on saying staying with the D16Z6 lol. I don`t have a problem with that, my only concern is hoping that my block is in decent enough shape to re-build.

curvy95honda

Sorry, let me clarify....

Drive what you have until it dies. Hopefully by then your JDM B18 will be ready to install. If you are worried about your stock D16Z6 dying before the JDM B18 is ready, the JDM D16 version is the quickest and most cost effective overall. The whole process of getting anything rebuilt is costly, labor intensive and time consuming however with the swap to the JDM, you get what you want delivered on a pallet and install it.

Any of the internet JDM engine vendors can usually get you what you need even if its not listed. You just have to get a quote or call and ask and be sure to get a quote on shipping sometimes that'll be a deal breaker. Either the JDM B18 or the JDM D16 will most likely last you another 200k miles even without the rebuild.

This is my backup plan if my D16 dies however I can think of a much better way to spend my $1000 than on another stock motor so, hopefully mine lasts until I too am ready.

Like sohcdelsol said, unless you're willing to shell out some serious coin to get the reliability and performance, the D16 will not perform the way you want it to. However you will feel immediate improvement out of the swap to the B18 without any upgrades. The difference in cost between the two motors is nothing compared to the $/HP youll spend getting that D16 just up to where the B18 is. Plus, your transmission problem is solved at the same time because you're gonna get a quote for the JDM engine and trans.

Better?

Better thanks lol. If I decide to go that route with th B18, are the motor mounts the same as my D16 in my '95 civic?

grumblemarc

iTrader: (4)

Nope.

Blacknight117

iTrader: (1)

I didn't think so...so much for an easy swap lol. Would I be dumb to throw a ram air intake and a new intake manifold on my current D16??

curvy95honda

If your motors tired, it might be a bit over zealous to add intake components. Might just shorten the life even more.

Those B18 motor mounts for the 95 civic are a dime a dozen thogh. The nice engineered ones are a bit more but, well worth it. The whole upgrade to the JDM B18 isnt that much more work than the install on another D16, respectively.

I feel you on this, I ws dead set on the rebuild of my current D16 too but, my bro showed me the light and i've never looked back since...

Waste of money. Put it to use where it will matter.

projekz

I'm in the same boat as the OP. I'm just gonna pick up a used D16z6 engine and go to work on it while I'm driving my stock one. Bisimoto has a great selection of parts for the Z6 and I plan on getting a fun daily out of it.

Blacknight117

I now have two options. Buying a bare D15 or D16 block, and build it up with good internals. Or, I can buy a JDM B18 and drop it in.

vondudka

Personally, I'd go with the B18. Unless you're planning on going boost right away, you know what it is like to drive a D. It leaves a lot left to be desired. I just blew my D and unless I can find a really cheap one to throw in for now I'm just going to mildly build a streetable B18. So it really depends on what your goals are. The B18 will still yield you more power later on. Plus B series parts aren't crazy expensive anymore considering everyone is going K.
