D15?

[gimpyben]

Anyone know of any worthwhile mods for the Honda D15 series of engine?

[Shaman]

Sorry. What car did that motor debut in?

BTW, congratulations, you have twice the digital songs I have and I have more than anyone I know. :)

[gimpyben]

Debuted in the original CRX Si.

BTW, soon I will have more songs, I just bought a new 80GB HDD I'm dedicating solely to music. You want an FTP account?

[Shaman]

Heh. Dang right I do. :)

I have two 80GB drives mirrored so I don't have to back up. I hate backing files up on tape... takes so long.

I know you can do a reasonable amount with those motors. #1 on the list would be turbocharging, I think.

[gimpyben]

I was thinking turbo too, because by Honda standards they have a pretty low comp. ratio.

The D15 is a sorry ass motor with pencil thin rods and a horrible tranny to go along with it. Boost would bust it in sixteen different pieces. Have a nice day.

[Shaman]

Heh. Well there you have it. More than I could tell you about it. :)

[RacingManiac]

now, where did that guy came from?

That's why I'm looking for a B18. :D

[Shaman]

O.K., I'll bite. What's a B18?

It's obvious I'm not a Hondaphile, so I'll just drop any pretentions of being one. :)

[gimpyben]

Integra 1.8L engine. I'm hunting for a VTEC variety. A B18C5 would be nice, but one would cost more than my whole car.

[Shaman]

Turbo B18s, now that I know them, are pretty grunty. There's a guy around here that beat me last year, much to my amazement, in his Civic. This year I pounded him pretty good with the suspension mods, but... jeez... turbo B18 in a CRX... :)

[gimpyben]

Well, I have an 87 Civic Si, so it's a little heavier than an CRX, but the same basic idea. :D It'll be expensive, but pretty insanely fast as far as I'm concerned. You got beat by a Civic? Must've been quite the Civic....

[Shaman]

Well, I discovered that his suspension and Hoosiers meant more than the motor. On the straights, it was quick but once i moved up to a mod suspension and put some R compound all around, I was pumping him right full of V8 rounds. :)

[gimpyben]

Still, not shabby for a >2.0L engine. :)

[RacingManiac]

you meant < 2.0L?

[gimpyben]

No, the alligator only eats the bigger number, don't you remember elementary school.

Read: "something" Greater(>) than 2.0L, isn't the "something" the 18B engine? Which if my guess is correct, 18B is a 1.8 liter?

1.8 does not > than 2.0.....

[gimpyben]

Hell, no wonder I failed my algebra class last semester.... :mad:

[Shaman]

My motor is >6.2L

heh

Since your engine bay is so tight and your car is so light (that rhymes btw) I would buy a HASport (www.hasport.com) mount kit and put a B16A in there. Since your car is under 2000lbs (as far as I know, it can't be much more than that) you can make the power-to-weight ratio work for you and have a really kick ass car. No need for turbo. Suspension parts for those 3g civics/1g crx's are getting hard to find but if you hang around autox's or road courses, there's generally some old fart with a nice example that can point you in the right direction. I think it's the front torsion bars that are becoming a PITA to find lately. You can put down around 180hp to the wheels with all stock Honda parts if you want, which is around 205-210hp at the flywheel. If you want an example, http://www.g-speed.com/eg2/ is useful. He would find even more power with the use of Endyn's Roller-Wave piston technology and headwork (swirl is cool. www.theoldone.com).

Um yeah, later.

[gimpyben]

The only thing that pisses me off about the suspension is the solid axle rear.

[MikAnchovy]

First of all, I'm surprised to hear bad stuff about the D15. I thought it was a good, flexible engine that was easy to tune. Oh well...

Gimpy, if you do want to go turbo + 1.8 litre, you may as well just go D18. Lower compression ratio, so you could crank the boost more easily. Of course, you'll want a trans. that can take the power, and a suspension that can put it down. With an unbuilt, turbocharged D18, I'm sure you could have over 200hp...

[gimpyben]

If I'm doing a swap, I'm getting VTEC, that's all there is to it.

[SkyeC]

What the cac is a D18?

[Shaman]

I assume you mean "cack". My favourite insult is currently "shaddap, cack-hander". :D

[MikAnchovy]

D18 = 142hp non-VTEC RS/GS Integra engine. Gimpy, please reassure me that you don't want a VTEC engine just so you can put a big "V-TEK" windshield banner on your car... :)

[gimpyben]

I do! :D

Actually I want one so I can get one of those HKS Super-AFC things to control it. And then if I turbo it I can control when the VTEC kicks in relative to the boost so I can get a good launch.

[SkyeC]

There is no such thing as a D18 in the D series engine family. What you are talking about is a B18.

The HKS Super AFC is a low-tech piece of crap. You want an A'PEXi V-AFC. VTEC isn't even good for high power forced induction. There's way too much overlap on the high cams. A lot of people just disable it completely. You also get a lot of a/f "suck-out" at VTEC crossover which is a bad thing when your car is boosted and sensitive to the a/f ratio moreso than an NA car. VTEC is GREAT for NA for turbo but leaves a lot to be desired. ;) It's not that bad for low power combos though, being around 350hp or less. I dunno what you mean by tuning the VTEC crossover for your launch. VTEC can't even come on until 20mph so you can't LAUNCH at VTEC although milliseconds after your tires start spinning to an indicatd 20mph you can... hehehe.

That paragraph had way too many 'vtec's in it.

[MikAnchovy]

Sorry, you're quite right SkyeC... the engine I was referring to was the B18B. In any case, I still think it's the motor for Gimp, because the lower compression ratio would allow for more headspace with boost levels before an engine build-up would be necessary, and because at least around here, there's 10 '94-on Integra GS/LS/RS models for each GS-R. But hey... I'm hardly a Honda expert... it's your choice Gimp. Just don't do the windshield banner :)

Of course, it should be clear that, as good as the B18B/B18C are, none can match the SR20DE :D

[gimpyben]

What I mean about the launch is that say you have a car that light with 300HP.... Well, on street tires that thing could easily bust loose at 20, to increasing the revs at which VTEC is applied would counteract that tendency to some extent. I think I probably will end up going with a D series engine though, just because around here they are much easier to find.

[ADAM]

forget the sr20de.....my ka24d will kick its butt

why mess with 2l when you can have 2.4l :)

[Chris P]

The D1X engine is not a piece of junk that will blow up with the addition of forced induction.

EXAMPLE: For the first gen CRX, Mugen came out with a Turbo CRX. This did a very good job propelling the car. I believe they called it a “TURBO PRO”.

And yes I do have evidence...........look below

Now about the B18 swap, I was at Ken XXXXXXX's shop on firday, he has a turbo charged B18 with a Type-R tranny and LSD to get the power down to the ground. Before he added the turbo he was doing 1:36's around Mosport Big Track. Yes is done to a 1st gen CRX.

Last year he did Drags with the car (low 11's ET), for 2001 he will be racing it in GT1 Ontario Change Cup. The car puts out over 400 HP AT THE WHEELS. The car also has a lot of bracing to stop the engine from ripping the car apart. He actually had to cut out part of the firewall to fit the engine in to place. Only wish I had the money to do that to my car. :)
If you want to go have a look at it, i can give you directions and his phone number. His shop is located in the same plaza as Auto Cosmetics (Tony M's company).

BTW he is thinking of running a few SOLO 1's next year………

And for the record, my Koni shocks were worn out last season, the fronts had very little damping effect, and all my bushings where cracked and some weren't even on the car anymore. I will be replacing both for next season............
Thus, Be afraid, be very afraid..........

Here's a link to the website for more parts for a 1st gen CRX/3rd Gen Civic

[Shaman]

Heh. I noticed your shocks weren't really all that wonderful, but you seemed to be making plenty of what you had. :)

[Chris P]

Yah i was really suprised that the Koni's where so bad.

And here i thought the car was close to it's limits............
not even close



God i hate body roll

Very cool turbo kit for the 3rd. gen Civic... is it only for PGM-FI cars, or would it work on carbed Civic/CRXs as well? I'm gonna have dreams tonight of my parents' old 1985 Civic being turbocharged... :)

[Chris P]

I believe it's only for the FI models.

[B18C5]

How about building a ZC? It's still a D series motor but you've got 2 cams, it's cheap and no VTEC. 130 horse stock and many D15/D16 parts will fit with little or no modification. Plus it should be easier to install since the ZC is basically the same block as the first generation Integra. I think only the engine mounts are different, so they can be grabbed off the D16 Integra.

There are quite a few turboed ZC motors in 2g CRX/4g Civics if you want to do a search. I don't know if many people have tried it in the 1g.

Actually, now that I'm thinking about it, if you're building the car for forced induction and are going to replace everything anyway you can probably get away with building the D16 teg motor instead. I think the only fundamental differences are pistons and cams which wouldn't matter as much when you're going FI.

[MikAnchovy]

Thanks for the responses guys, but unfortunately, I'm not in a position to do anything with a 3rd. gen. Civic. I had an '85 Civic GL Hondamatic as my car, and I loved it very much. Unfortunately, the Hondamatic transmission didn't enjoy neutral drops and/or other forms of abuse, and it went south. When the transmission died last September, we didn't think the car merited the cost of transmission replacement, even though it wasn't super-rusty and it only had 170,000 kms on it. So my parents replaced the Civic with a 2000 Corolla, and three weeks later I got my NX2000.

Sometime later in life, after I get my degree taken care of (I'm in grade 12 right now...) and depending on what kind of state my NX is in by then, I might get a project 3rd gen. Civic and do a swap. I think that I'd be most likely to just find a near-dead 1st gen. Integra and steal the motor, the transmission the brakes and the wheels. Then I'd go hunt down Riceboys... :)
