Started tearing her down a couple nights ago.

Getting started:
https://www.miataturbo.net/attachmen...ine=1448044666

I pulled the intake manifold off and disconnected the harness to get it out of the way. This gave me the opportunity to get a look at the hole a little bit better:

The rod karate chopped the oil feed cast into the block. When it let loose I was quick to clutch in and cut the ignition. My only hope is that the crank is still salvageable. Im sure someone could get some use of it.

I then pulled the turbo setup off and put it in a bin to keep it clean and safe.

Boost in a box:

After the turbo stuff was out of the way, I started pulling the AC bracket (front torque mount) off, underneath which I found another window in the block:

Here is how she sits at the moment. Im ready to get this old heap yanked out:

https://www.miataturbo.net/attachmen...ine=1448044666

The only question is what do I put back in?

Ive been talking to a few people and it sounds like my best bet is picking up a low miles JDM imported B20B, which was found in the following vehicles during the late 90s:

https://www.miataturbo.net/attachmen...ine=1448044666

and of course

https://www.miataturbo.net/attachmen...ine=1448044666

and then I have a buddy who rebuilds B series transmissions, and Im planning on getting a Integra GSR box from him.

Just to put into perspective how much better the gearing is between B series and D series, check out these here graphs:

The Integra GSR transmission (again, that is the one I want if I go B20B) vs The shortest D series transmission (the one I wish I had on my engine before it 'sploded):
https://www.miataturbo.net/attachmen...ine=1448044666

and here is the GSR transmission vs the transmission I actually have in the car (Civic DX trim):
https://www.miataturbo.net/attachmen...ine=1448044666

I think gearing alone will make the car a lot more fun, not to mention another 400cc of earth shattering honda torque

It has been a long time since Ive updated this I havent gotten much done because Im lazy and its hot out but here is the super fast cliffnotes of the past 8 months.

Got sweet JDM truck engine overnighted from Japan for $300

Chinese turbo parts because fuck it #baller
Attachment 232765

Spent a shit load of money on a transmission (I miss D-series already) that was recently rebuilt. Of course it had stripped mount holes because Honda kids are retarded (myself included probably).
Fixed it with standard bolts to confuse future owners.
Attachment 232766

Attachment 232767

Tried to install engine in car. Didnt fit. CRV motor mount is all stupid, almost as if it wasnt designed for Civic. Get that shit out of here.
Get full of fuckit attitude, buy expensive aftermarket mount instead of filling a used stock mount like a true #baller would.

Why did half my post disappear? Was it edited?

No one edited it. That is all I saw before you posted the update.

The B20 is notorious (widely known) for being the weakest B series block by a huge margin. The sleeves are extremely weak. Not trying to crap on your plan, but its known for failure in the Honda world. Just do some searching around google, it will be quite evident. A B18B would be a much better option, and it would make more power and torque, because it can handle those power levels without failing. The .2 litres won't be missed.

But, good news is you would only need a B18 short block now if bad things happen, since you have the top-end already.

Only commenting on this part because, unlike Miatas, I am not new to the Honda boost world. This is a complete pipe dream. Literally the same as saying a 1.6 BP will handle 300 TQ at 3000 RPM, no way in hell. Do a little searching around. Even the much stronger B18B would hold that power and torque level for only a "borrowed" amount of time.

I know all about the B20 sleeve issue. Things that are "widely known" in the Honda world, are frequently bullshit.
Are they weaker than other B-series? Yes. Will they crack at a mere 300 HP? Probably not.
300 HP is the upper safe limit with P75 rods, the B20 sleeves will reliably hold more than 300 HP. Ive done it numerous times. One of my long time tuning customers has been making right at 300 HP for several years now and he even tracks the car occasionally.
There are lots of things I have to worry about on this setup, the sleeves are near the end of that list.

Well fuck.

More late update cliffnotes:

Got LS Integra intake manifold because the CRV one would stick through the hood. -1 torque, +1 aerodynamics.

I decided to clean up shop a bit by selling a bunch of random shit as a lot. All this garbage priceless Honda parts went for a grand total of $80
Attachment 232759

Unfortunately in this lot I accidentally included the stock 60mm throttle off of the B20 engine, thinking it was a shitty 55mm D15 throttle. Turns out the one I set aside was the shitty 55mm.
Well shit. Fuck it, 55mm has more velocity for throttle response or some shit. #racecar Had to make sweet blockoff plate to prevent crazy vacuum leakage.
Attachment 232760

Put turbo stuff on engine and starting mocking up. Charge pipes dont fit anymore. Stupid engine is different size than old engine. Why did Honda have to make everthing so difficult? The forums told me it would be like legos, not an erector set.
Attachment 232761

I later bought a 3" stainless mandrel bent downpipe from a guy for $30. It was for a different manifold, so it would require careful modification to make it fit. Since it was such a nice piece, I decided the best thing to do would be to MIG it together with mild steel wire.
Attachment 232762

Shit actually fits well. WTF. Its almost like effort was applied.
Attachment 232763

More belated updates with sarcastic commentary coming soon.

TQ kills things, HP not so much. FWIW, B18/20 rods are identical, P75, and hold the TQ just fine, hence why B18B's hold the power fine. The sleeves are manufactured differently, and are weaker, by design in a B20. I am not going to argue, simply because people don't search Honda B Series turbo build info. on a Miata site, so it matters none that you are wrong.

Cool little build tho! In for updates, reminds me of the old days.

This is a bit of an oversimplification. RPM plays an important roll in this issue in my experience.

I know. Hence why I said
I know.

Eloquent statement, old chap.
Since Im wrong, can you please tell me what the safe limit for the B20 sleeves is? The B20 is much, much cheaper than a B18B, so I want to know exactly how much more power I could make for my money.

Updates continue (still not caught up to current).

Putting a B-series into a Civic, that was designed for a D-series, means that certain small things need to be changed. Luckily the 92-95 Civic chassis is very similar to the Acura Integra chassis, which came with B-series. So of all the Civics, the 92-95 are pretty easy. You basically just need a different transmission bracket and axles, plus some little odds and ends. One such odd and/or end, is the throttle cable.

It was immediate obvious that the stock throttle cable would not work, so I go to Honda-tech, repository for all things stupid and also some honda technical information. Here I read that I needed to just buy a new Acura Integra throttle cable to make it work, and I also read that if someone was so inclined to use their existing cable with a modified bracket, that this someone would be both "ghetto" and "retarded". I have no desire to be either ghetto, or retarded, so I bought a nice new official Honda throttle cable on eBay.

Now, I thought, I was definitely working smarter, not harder. This would be the moment that turned this whole build around. Things would start coming together quickly and easily as I took the path of least resistance through careful research and smart purchases.

Upon receiving the cable, I installed it and found...

THIS FUCKING SHIT DOESNT EVEN FIT WTF HONDA-TECH!?
Guess who is retarded now!? Me. Im retarded.

Cut. Weld. Bury the pain. Move on.

Back to cliffnotes.

Made pipe longer so boost can go where it goes

Traded old D-series Garrett T28 GTiR turbo setup for brand new turdbonetics ball bearing T3/T04B
Attachment 232754
Decided good turbo would make car too fast. Chinacharger is much more sporting. Sold for roughly what I originally put into the T28 setup.

Bought Koni Sport shocks with Ground Control coil/sleeves from some dude.
Attachment 232755
Again, car may handle too well. Dont want to attract media attention when I start demolishing lap records. My friend is using them on his Civic instead.

Bought a nice Honda so I dont have to think about how ugly the green car is

-and here it is. All ready to be tuned and make boost.

Hopefully soon Ill be posting videos of it doing the full tilt boogie and spinning these shitty old tires.

Lol I don't post from the garage.

Wrong thread..

I realize I'm bumping this. Not gunna lie though, I think you mounted this bracket backwards, i.e. it's supposed to angle in towards the manifold.

Oh damn. I forgot about this thread.
As for that throttle bracket. I have no fucking idea. I ended up cutting it up and welding it together so it worked.

So after playing around with the CRX (Ive always wanted a CRX) I realized that it was the car that I was interested in making "good".
I had fun building a dirt cheap street car with the green civic, but the long term goal of developing it into a a good race car was misguided. The chassis is just not as good as the little CRX. So I shined it up a little and put it up for sale. Here's the last pic of the engine bay before selling it (minus the air filter):

Some kid drove all the way up from Tampa to buy it. As he drove away I thought for a moment about how much of a POS it was while being pretty quick. Hopefully I didnt kill a teenager.
