D15 Q
 

how much boost can a stock D15 hold safly to be trust worthy of a cummuter car.

Re:D15 Q
 

10 pounds ;)

Re:D15 Q
 

i know the car wont go for 3 months on 10 pounds with out blowing up.

Re:D15 Q
 

you know? youve boosted a d15 before????

it depends on to many variables, btw why are you gonna ask a question like taht and then tell spenser a guy who has turbo'd D's before that hes wrong, your a tool

Re:D15 Q
 

as a cumeater car I'd say 16psi minimum. and how much can it hold shaftly? probably 28psi.

Re:D15 Q
 

your saying a stock D15 with 183K miles on it and the tranny will last more then a year redlining it sometimes and driving more then 3k miles a month with 10 pounds if this is true.. then why the trubo a B16? and be happy about it.

why i said it wont becouase i all i hear is stock d15's blowing up after a while with only 8 pounds.

Re:D15 Q
 

what a tool.
why you putting words in his mouth.
you ask a question and you think you know the answer already.
what kind of setup do you have?
like fsu said, there are too many variables.

Re:D15 Q
 

stock d15 only thing i done to the engine is air filter and nkg spark plug wires and spark plugs.

Re:D15 Q
 

Seriously, you need to give more info. For instance, what turbo? Like what kind of horsepower are looking to make? 10 psi on one turbo is not the same as 10 psi on another. 6 psi on one turbo may make more power than 12 psi on another. You need to be thinking more about power levels than an amount of boost. And to answer your question, in my opinion I would stay under the 200 whp level if you want it to last. Shoot for around 175 whp to play it safe. It seems like you are very concerned about reliability. Make sure it is tuned well and it will last. Your car should be plenty quick. And also do an mpfi conversion if you haven't yet. If its not quick enough take a little risk and turn the boost up a bit.

Re:D15 Q
 

Boost on a little rhb5 is totally different than a big t3 so psi is just a general term.

Re:D15 Q
 

ok.. say a t25 or a 14b for the turbo with 6psi and i don't know how much hp.. probly 150.

Re:D15 Q
 

What type of fuel management are you gonna run? Are you gonna have it tuned?

Re:D15 Q
 

You will be fine with either turbo at that boost level. You are really playing it safe. I'd say you could at least go to 8 psi on those turbos. But of course you could kill your motor at 3 psi. if you are running lean or too much timing so your tune is extremely important to your engine lasting.

Re:D15 Q
 

if u dynotune ur d15 ur wasting ur money cuz a new block can be had for 50 bucks

Re:D15 Q
 

Very true. Sure, you can pick up another d15 block for cheap, but who says he wants to do all that work cause he blew up the first motor due to no tuning. I wasn't suggesting to dyno tune the d15. It would be in his best interest to hook up with someone with a wideband to help him out with the tune and at least get some decent afr's.

Re:D15 Q
 

I know the blocks are cheap but then you have to take time and labor into consideration. I'd rather spend $200 on a dyno gettiing my car tuned right then not tuning at all and have my motor blow evey 3 months. Yeah only $50, but what about towing costs when your assed out on the side of the road, etc.... just my $0.02.

Re:D15 Q
 

He needs to worry more about fuel management than what turbo to run. B/c he wants reliablity than hp, so read more on what fuel management to invest in. And yes tuning is very important in any turbo kit.

Re:D15 Q
 

you tell em nick ;D

Re:D15 Q
 

Some times u could get a block for FREE ;). If u want to play it safe, just get xtra parts of certain things like blocks, trannies, mani, turbo's,etc. That's if u have the funds to do so, and even then u could get most of these things free. U gotta look around for a while tho. That's how i get my parts cheap/FREE.

Re:D15 Q
 

justrun a good fuel setup and tune it decent. You dont want to be stuck on the side of the road waiting for a tow when you are on your way to work. Id run 10-12 psi and not be scared at all

Re:D15 Q
 

i agree if you want reliability boost is not your issue as much as your fuel/timing management

also as they are saying bc of turbo size difference 10psi on one turbo isnt on another, a 14b at 10psi is only a fraction of the CFM of say a T88 on 10psi

Re:D15 Q
 

i'd probly get like 450 dsm's and use uber data or turbo edit. i forget what ones for my car... and i would rather spend money on tuning it right the first time. but also a built motor would be better. if i can get one for under 700. sence i'm geting my tax return soon :D

Re:D15 Q
 

im surprised at everybodys response most people would have just told this guy to do some research thers plenty of posts about how much this motor can handle. 4gh91 do some research if your so concerned about reliability dont go trubo unless you got alot of money to spend on tuning or do a motor swap

Re:D15 Q
 

ive had my d15b2 up to 13 or so psi :o its on a te04h (small turbo) but im boosting about 7psi daily on it now. tuned with TurboEDIT and a wideband ;D tools of the trade

Re:D15 Q
 

um isnt this the reason HMT is here, to use/learn uberdata and turbo the car without spending alot of money?? ::)

Re:D15 Q
 

true but if you look at the first people that started this site they were using true standalone ecus zdyne im just saying that if you want good reliability you have to pay

Re:D15 Q
 

they were using Zdyne cause TE and uberdata weren't availble at the time. ;)

Re:D15 Q
 

which would you say is safer zdyne or TE

Re:D15 Q
 

T.E 8)

Re:D15 Q
 

depends on who is tuning it, not so much which program imho

Re:D15 Q
 

??? Why would TE be safer than zdyne?

Re:D15 Q
 

Why wouldn't it. ;)

Re:D15 Q
 

T.E. is a front end to modify a PGMFI.org bin, or "program".

in fact, it's the PGMFI.org rom that would be "better" than Zdyne, not TurboEdit.

if you were so inclined, you could edit the rom with a hex editor, and then you wouldn't need TurboEdit.

but who the hell wants to do that?

Re:D15 Q
 

Oh, come on Spenser. WTF. Thanks for not answering my question. That is a good solid answer. ::) You could use zdyne or turboedit to alter you fuel and ignition tables to achieve the the same end result. I don't believe one is safer than another. So prove me wrong or don't post that ----. :P

Re:D15 Q
 

you are ------- dumb. what are you trying to prove, that T.E is more dangerous then zdyne? can you prove it? No. Besides, Zdyne is 1000 bucks, T.E is free. ::)

Re:D15 Q
 

turboedit is much safer than zdyne.
cuz if my wife found out i spent 1k on an ecu, she would kill me. she already knows i can use t.e. and uber on the stack of ecus i have!

Re:D15 Q
 

LMFAO!

Re:D15 Q
 

??? ::) I'd like to start off by saying ---- you Spenser! Yeah, I'm ------- dumb. How? You are an -------. You can't even answer my question. You are the one who seems to know that turboedit is safer, but can't prove anything. So you just go ahead and keep posting bullshit that you have no experience with or can't prove.

Re:D15 Q
 

Hmm, Dude, I appologize. I couldn't tell if you were being sarcastic and/or trying to bad mouth Turbo edit, or if you honestly didn't know which one would was safer. I honestly can't say which one is more safe, and since T.E is no more then a hex editor that edits a 'code' that is based off the OBD0 code just like Zdyne, its safe to say that there really is no difference. as long as Turbo-edit functions correctly (which it more or less does) then they are both the same.

I really don't wana bad mouth T.E or PGMFI.org cause they are such great things, but you have to keep in mind that T.E is somewhat Beta and there may be problems yet to be incountered.

Re:D15 Q
 

ok, appology accepted. Thanks for stating your honest opinion. I was not being sarcastic and definitely not bad mouthing turboedit. I just wanted to know why you thought turboedit is safer. It could be a fact that I'm not aware of or it could be your opinion. I just wanted to know. :)
