My parents would kill me. But if he has a SOHC VTEC motor I'm all over it. 75lbs less, not much less power, I could run in a stock class for AutoX (if someone really wanted to protest they could... but whatever), and I could sell my b-series for a grand or so.

Anybody willing to house a motor for me until I rent a storage place this summer?

i could probably store it for you if you wanna give me your b-series motor...

[Mike]

You already have one silly, no need for two

i wont have it anymore when i blow up the motor

d-series engines are the biggest pieces of crap ever, just one of my friends has had 3 spin a con rod bearing in the course of about 6 months. He's now running a d16z6 turbo'd in his crx which suffice to say isnt running very well at all, so he took all the turbo stuff off trying to run it NA and it still has issues. He's running a Zdyne stand alone engine management too. I don't even think i'd take a d-series for free unless of course i had some sort of go cart frame to put it in hehe.

[Mike]

lol, they're nearly as bulletproof as the b-series motors. sounds like your friends got some dead motors to begin with. any idea of the mileage or how hard they had been ragged on before?

[Kaan]

i want one! :twisted: d series build?
all over it like white on riceR

[DierwulfBL]

well we rebuilt the crank on one and who knows maybe we didnt do something right but we were running em pretty hard, the first was a si crx d16 no vtec and we had it around 7k rpm all the time, the newer d16z6 we got it really cheap and pulled the oil pan off and saw that there was no bearing left on the crank for the 4th cylinders con rod. Anyways, i've had d16s apart before and know whats up with them so a d16 build would definitely be up my alley, im just sayin SOHC is no good and a lot of the d16z6 civics/del sol si's ive driven didnt feel like vtec kicked in, mighta been a fluke though who knows, atleast it definitely wasnt noticeable LOL. But if we built a d16 right, we could make a fairly nasty NA engine or an even better turbo engine. My friend with the crx makes 215whp with his d16z6 turbo'd. Stock internals you can boost up to like 11-12 psi no problem cause the compression isnt too high, just gotta put a thicker head gasket to bring the comp ratio down a bit. If they're regular d16 with no vtec i wouldn't bother messin with it though, those engines are just lackadaisical. A crx is definitely the only home for one, anything else is too damn heavy. Anywho, id have space to store the engine if i wasnt already storing a 4age 20v in my basement :twisted: also michael what b series are you running, i thought it was a GSR engine? or maybe i just assumed it was, i guess when i hear of people swapping a b18 into their hatchback i automatically assume they went GSR, one of my other friends has a GSR in his crx and ran a 12.3 at nopi nationals with full interior, id definitely stick with the GSR engine especially since you got all the b-series mounts and stuff, converting back to d-series would kinda be a pain, unless of course you're paying someone to do it for you :?

[Mike]

Yeah the non-vtec d-series motors are worthless. You can call me Mike btw I'm running a B18B, out of the LS. Nothing amazing but it does the job. Problem with a B-series in a hatch is it puts you in to a swap/unlimited class in pretty much all of racing, I get my 140hp ass handed to me quite easily by some of the crap I have to face. My only option is Honda Challenge H1 (wheel to wheel racing) where I'd pretty much have to get a GSR motor, but that is a few years off so I've got time to figure out what I'm gonna do.

[Evan]

sounds like user error

[DierwulfBL]

b18b make for very good turbo engines, that was the original engine we had in mind for the crx, but decided to keep the engine mounts and transmission the same since the clutch was still good. I now see why you would want a VTEC d16z6/z8, theyre rated 130hp which yea is only 10 less hahaha and since you have to go against other swapped hondas you most likely are battling with 140hp against some frankensteins, b20 block, b16 head which make some impressive numbers hehe, or even worse against an h23a1 which is like 210hp. I definitely feel your pain there, but im not quite sure how all the categories work and stuff since i havent really looked into official racing, mostly just street racing :oops: and we live out in the country kinda so we have road races on the curvy country roads. But then again, road racing definitely isnt about just power, more about grip and braking, my tiny 1.6L DOHC has beat 3.2TL acuras in road races just cause it grips like a booger and slows faster than a post-war economy . I'm kind of interested in autocrossing i just need a lot more information, is there a website i can check out that would be beneficial to the autoX around here? thanks.

Yikes... seems like there's some poor tech being thrown around here about the D-Motors.

Garbage in, garbage out, with anything. If you start with a junkyard motor that was run low on oil and has spun bearings, of course its not going to last very long. The D16Z6 can make pretty good power if built, and can be built with almost entirely OE parts for a good N/A setup. They're also dirt cheap to pick up good, running motors to replace.

The D16A6 (CRX Si) motor will put down ~120 whp with a good bolt-on package and a freshened and *mildly* (just port matching and a small milling) prepared head. Certainly no slouch if you have a gutted CRX or hatch and want a cheap motor.

I would really like to do a Z6 in a hatch, i think they can make pretty damn good power (say ~150-160 whp) and remain reliable, or run 8-10 psi of boost. There's alot less cost associated with putting a D-motor in a hatchcrap, since you dont need motor mounts and axles and so forth to run it.

The B-motors will make more power, but weigh 50-60 lbs, cost more to buy, and cost more to swap in. It all depends on what you want to do and what you want out of the motor/car.

i've passed a couple B series with my D series on track :twisted:
then again i dont mind taking my 177k mile motor up to 7k coming out of hog pen... oh wait... yes i do! lol... she's gonna blow this weekend if i cant figure a way not to hit 7k in the pen! she's old and weak but she gets the job done... haven't been to the shop in 1 1/2 years of owning it. throwout bearing and all even the clutch is hang'n in there!

[DierwulfBL]

yea its all about power to weight, and crxs are hella light, we got an HF shell just chillin in my friends driveway and you can literally pick up the back end and toss it about 2.5 feet, it's just crazy, but yea, we completely rebuilt the bottom end on a crx si engine and it threw a bearing about 6 weeks later but yea, we completely stripped that crx out...........completely, im not sure if we even left the speedometer in, just had an after market tach chillin. Dash was completely out looked like the car had been stolen hahaha. The only mod he had was a K&N air filter and he was beating si civics. But after it spun another bearing he just opted for a turbo d16z6. But yea d-series swap is DEFINITELY much much much much easier to do than a b-series. We did the d16z6 swap with a cherry picker and a floor jack/car jacks in my friends driveway, that sure was fun. I told my friend about the car show and told him to get his rex up here and he said he might so you guys can check out the stripped out rex makin 215whp, its off and on though sometimes itll run perfect, sometimes itll idle surge, hes getting it all worked out though. Anywho new chappelle on soon, im out.

Plastigauge? Runout? Line-hone? Etc....

If it wasnt done "right" i'm suprised it lasted longer than 6 days

[Chris]

what's all this hate on D series engines?! I know they are fairly slow but mine has been extremely reliable and is easy to work on. Its my first car so I can learn to drive better on this before upgrading. I wouldn't call them crap, just slower. they will def last forever (if taken care of)...

[Team]

You can buy my a3 if you would like... :wink:

[DierwulfBL]

yea, i guess i dont see them as reliable because my idea of a bulletproof engine is the h23 or the toyota 5s-fe. I've seen both of these engines mistreated beyond belief and still make around stock power. My friend drove his si lude for 25,000 miles on the same oil and filter, and he ran his intake open element (no air filter whatsoever). granted he burned a quart every 600 miles or so he figured that he had done a couple of oil changes over that time. I recall days riding with him where he'd be taking his car to 7000 rpms for about 15 minutes of hard driving just screwing around, and his oil light would come on. He'd drive to a gas station add a quart.......oil still not on the stick........add another quart........oil hardly on the stick..........3rd quart and it was where it was supposed to be. And i had pulled his dip stick one time and clumps of something came out on it........don't know what. Anyways.......that's my idea of a bulletproof engine. Seen about the exact same scenario with my friend who has a GT celica with the 5s-fe, 280,000 miles on the engine hadn't changed the oil in around 18,000 miles and still took it to redline on a daily basis. If you do that with a d-series.......just have another engine handy to swap out. I guess thats why i see them as no good, but i also see the engine i have in my car currently as no good even though everyone else says theyre "reliable" but i could complain just as bad about the 4a-fe line of engines seeing how theyre nearly identical to the d16a3. Dah well i guess my idea of reliable means that you can just be a complete idiot and not worry about anything screwing up, but im sure none of us here are even close to as bad with our cars as the aforementioned, cause that's just complete negligence

[.RJ]

cause that's just complete negligence

winner winner!
