In a couple weeks I'm getting a 14b turbo setup, I probably won't install it until spring next year kuz there's no point if it's gonna start snowing. Anyways, the question I had was: Pushing 5 psi on my stock d16z6, how fast do you guys think it will be? Keep in mind that I ran low 18's...lol...;Slap: I'm hoping it will be in the 16's area...
flame away...lol

the d16 can safely boost upwards of 11 psi on stock internals with arp headstuds & a good tune. dont be afraid to turn up the boost. 5 psi at this altitude is crap.

I agree with that @ 5psi. You should throw 10 on it though, you'll be happier that way.
are you going with a kit or are you buying one someone has already peiced together

That's crazy, you really think it can do that?

A friend of mine was gonna put it in his d16y8 (identical to my engine) but he bought a WRX instead...he has everything pieced together. Except the mounting plate? or something like that.

yea it should easily go 15's if you know how to drive. but yea, 5 psi is weak. at least run like 10 or you probably wont be happy with it.

yeah i had a Z6 with a 14B @ 8 psi and the ass dyno thinks it would have run a low 15 easily.
and yeah like everybody else says run AT LEAST 10 psi. only reason i was at 8 is beacause thats what the factory WG is set at on 14B's and i didnt have a boost controller at the time.

Are you guys sure my engine can handle 10 psi???
I mean I also want it to last me a while, or at least until I get enough money to get a new engine...maybe like a year or so...

I've got 10 months and 8000 miles on my y7 @10psi. Still runs great

Nice! Ok then I'll do 10 psi on it!

It's all in the tune, you can push a stock internal D16Z6 (with headstuds*) to 200-250whp without breaking anything as long as the tune is on. A 14b and D16 combo is a very nice setup, tune it right and you wont be disapointed and honestly at this altitude i'd run closer to 12-15 than 10; again as long as its tuned. If you dont have the EMS down you're not going to go anywhere.
*D series have a very bad problem of lifting the heads under high cylinder pressure (boost, NAWZ, stupidcharger etc). Even with a good tune it's not hard to lift the head and blow the gasket. ARP studs and a new MLS gasket take care of that, the OE headbolts just aren't up to the job on a boosted motor, everything else can handle it.

dude WTH with the mis info. This is not a d series issue. You can have this on any motor not intended for boost. Its just as likely to occur on B,K,H or any other make for that matter. 10psi should be a fairly safe level of boost with that turbo on your D. Precautions like headstuds are always a good thing but not manditory for boosting.

10 psi from a tiny 14b will be just fine. 10 psi from a T3/T4 might be questionable, but a 14B will work very well on it @ 10-12 psi.

Misinformation?
You go poll some numbers on boosted stock longblock honda motors and you'll find SIGNIFICANTLY more D's with lifted heads and blown gaskets on stock headbolts. I had the problem, friend's have had the problem it's a known FACT that D head bolts are not up to the job on a boosted motor.
However every B i've tuned on stock headbolts has never had a problem with stretching.
You dont even need to detonate to lift a head on a D, just making power will do it, add a small amount of boost and way too much timing (AFC hack, fmu bullshit etc) and you'll blow the gasket first time you hit boost.
Don't take my word for it, go look into it. ARP studs and a new hg are a cheap upgrade anyway < $100

:werd:
I ran into this issue with 7psi and a good tune, shortly after I turbo'ed my '98 B18B that had only 70k miles on it at the time. I've seen D-series motors have this issue too, but the B is certainly not immune. It seems to somewhat be a matter of luck, being that not everyone runs into this problem.
Many would also say that the D-series engines are also known to have weak rods... However, the only ones I see having a problem with that are ones that don't have a real tune and/or try to run an excessive amount of boost. All of the ones I've seen that were properly tuned and ran a reasonable amount of boost, did not have any rod issues whatsoever. David managed to screw up his turbo D16 pretty good (he was a noob, lol), but no issues with the rods with his VAFC setup, and it was dyno tuned by Tobi.
^ thats what i hear most often...its a cheap motor so people boost the shit out of it with no turn or bairly anything, then brag about it, so therefor other people take it as"o the d motors sux"

yea it will definatly hold 10 with a good tune and ARP studs..GL

*****NO!!! make sure that your fuel and ignition timing are appro-for what ever you are trying to achieve..... you can run upwards of 18psi on a stock honda block but there are too many variables you need to look at first.
If you like the bus go ahead and run 10psi and have fun.... want some good advice ask in pm. FYI d16z6 tend to max 230-250 whp. (reliable that is that i have done)
the d16 can safely boost upwards of 11 psi on stock internals with arp headstuds & a good tune. dont be afraid to turn up the boost. 5 psi at this altitude is crap.
haha agreed, and most deff get some head studs, the head tends to lift from the block.. I GOT ALL MOTOR UP HERE AND MY CAR IS GUTLESS!

All that money for a 15? Engine swap please.

An engine swap might give him a 15 when that turbo kit will net him 14s.

WOW this is the thread for me as I blew an a6 crx with a 14b. It was an 88 dx with an si block/trans and a z6 head. I started at stock boost (i would see 8psi with 2.5" charge pipes and a fmic) Car was greate, I never dynod it but it would pull mid 15's all day long on shitty street tires 14"s. I then got a home depot boost controller and slowly upped the boost to 15psi. boost is like crack, I blew the engine about 8 months after boosting. It was a bone stock mini me with reused head bolts.
my suggestion, dont get a boost controller and leave it at stock boost. Get a good tune with crome or uberdata and
leave dat shit alone.
this is coming from somebody who has blown 4 engines so far and working on number 5, check my other posts for the last engine i blew up. and good luck man

my friend ran a 14b on his d15b...he was running like 12-14 pounds. I wouldnt do anything under 10.
and ferrett these turbo setups mostly get done for under a grand. any honda motor thats gonna put him into the 15's straight swapped is gonna cost a lot more.

I understand that turbocharging the D16 can be done for cheaper than swapping an engine in first, but think about the long run. Sure, you can invest $1500 in turbocharging the d16 for a pretty decent boost in power.. then you can blow it up because you're running high 14's, or 15's at a safe level, and it's just not cutting it and you want more power. However, swap in a motor that gets you a very significant power jump in the first place (B18C, H22, whatever you Honda people prefer), and you get the short term satisfaction of having more power as well as the benifit of being able to turbo/supercharge it later for a MUCH larger gain.
Gotta pay to play, someone told me once

well whatever floats your boat...the argument will always battle on about the whole one cam two cam thing in the honda community. I believe that two cams are better than one, but my roommate believes one is better...he ran .3 seconds slower than me this season at bandimere. both of us were turbo'd, me on a b16 and he had a d15.
I paid 4000 for my setup, he paid 900.
its all a matter of preference.
the fact of the matter is sauccarl can double his horsepower to the wheels safely for roughly a grand. he'd be stupid not to. if he bought name brand new I/H/E he'd be spending close to that with shipping.
