HOW MUCH BOOST CAN I RUN?
 

hi...
i have a 91 civic with a d15b7 motor.

i have a 14b with a tubular manifold and 2.5 inch exhaust and toyota supra fmic with 2.5 inch piping....and 450cc dsm injectors and apexi.

recently i installed a honda metal hg and arp head studs to really crank it down.

last week i blew the motor bad...i fried the d15b7 pistons.....
so i was on a budget....so i did a little research....
i found d16y8 dished pistons stock bore and i used a d16y8 metal hg and i ended up with a low 8-1 comp. setup PERFECT FOR TURBO SETUP....

is 9 lbs conservitve for this comp or can i turn it up more ... 12 or so? what do u think...?

Re: HOW MUCH BOOST CAN I RUN?
 

ahh man with that turbo you could do 30psi easy! but i would not do less than 40psi, thats where its really efficient :y

Re: HOW MUCH BOOST CAN I RUN?
 

i will run with T4 ..quick spool with that engine..

P.S read FAQ guy.

Re: HOW MUCH BOOST CAN I RUN?
 

Dont listen to renr.. I would keep it anywhere under 25 psi on a t3/t4 turbo.. Your straight.

The 14b has the new Garrett Balistic Concepts triple ball bearing center section and of course the gargantuan T5 exhaust wheel mated with the 83 trim compressor wheel, so it's very capable contrary to popular belief. Of course that's the JDM 14b, so if yours is USDM or IDM (Icelandic Domestic Market) I wouldn't run it all, but if it's the true JDM 14b then it's easily capable of anywhere as low as 10psi to just shy of 60psi.

At 10psi it'll flow 650cfm which is about 400whp, but with the triple bearing CHRA it'll spool like lightning, so go ahead and run closer to 35-40 because that's the efficiency range which is right around 1250cfm.

Just tell everyone who asks about your car that you have the Mitsubishi Triple Ball Bearing Balistic Concepts JDM Garrett 14b T5/83 Trim Hybrid. They'll know what you mean :y.

Re: HOW MUCH BOOST CAN I RUN?
 

yea we know 25 lbs is good

Re: HOW MUCH BOOST CAN I RUN?
 

dude so many people have run over 30 on d15's there the strongest of the d's. i say 25 just to be on the safe side

Re: HOW MUCH BOOST CAN I RUN?
 

dude the d15 can run it easy no problem. who ever you are talking to dont know ----.

Re: HOW MUCH BOOST CAN I RUN?
 

ok i'll stop ------- with you. but you need to post porn.


to be honest 9 seems about right. that is what the wastegate is set at on that turbo and your little motor will handle it just fine. anything after that yous pushing it

Re: HOW MUCH BOOST CAN I RUN?
 

Why does his Y8 have D15 rods in it?


JP

Re: HOW MUCH BOOST CAN I RUN?
 

30 psi or bust, baby

Re: HOW MUCH BOOST CAN I RUN?
 

you should realli check out d16trbo.com... go read up nigga.

Re: HOW MUCH BOOST CAN I RUN?
 

yeah wtf?

Re: HOW MUCH BOOST CAN I RUN?
 

You mean like pistons and rods?? Thats sooo many mods?? Where did you learn your ----?? Umm H-T???

Go fist yourself and post porn.

Re: HOW MUCH BOOST CAN I RUN?
 

^^^^^^^CANADIAN^^^^^^^^^^^


this should explain everything

Re: HOW MUCH BOOST CAN I RUN?
 

Totally jealous.. I still have my y8 rods and pistons I just pulled out of my car.. You can have them for your kickass setup..



Yeah 25-30 psi coming. 350-400HP Y8 motor being built by me now..

Im soo ------- jealous.

Re: HOW MUCH BOOST CAN I RUN?
 

#1, Learn to spell, jackass.

#2, d16turbo.com isn't the site you're thinking of; its turbod16 (Still very gay.)

#3, this site has more than enough information about TURBOCHARGING. Why don't you direct the canuck to a sticky in here instead of another site :1

And the OP should just grab a rope. :)

The CRX has been gone for years, noob. Pathetic attempt at trying to belittle me though, I know you can do better. :3

Re: HOW MUCH BOOST CAN I RUN?
 

something makes me think this guy wont be lasting long

Re: HOW MUCH BOOST CAN I RUN?
 

THis is a site where we all learn what were doing before we go putting turbo's on stock engines. If youve done so little research that you don't understand what the limits of your engine are............Then your not ready to even start buying parts yet.
Our rudeness has nothoing to do with nationalism . It's because weve all learned and earned what we know. Your asking for a handout Just like your country will ask for aid from the US when you get your next natural disaster.

It's the Stanley Cup thats hockey and americans rate hockey on he same level as soccer It sucks. just a game for third world countries to entertain there peasants with.
He's Canbodian that explains this whole thread.

Re: HOW MUCH BOOST CAN I RUN?
 

Yeah, but you're still Canadian, toolbag.


You want a real opinion of your ------- MAD TYTE JDM DISHED PISTONS on your pencil thin D15 rods? If the C/R is 8:1 like you stated, I wouldn't go past 10psi on that 14b if it's tuned right that is...

There, happy?

Re: HOW MUCH BOOST CAN I RUN?
 

Are you still ------- here? You will get banned just like rey rey.. As a matter a fact the way you post you will exactly be banned like rey rey.. So get fucked beotch.. You came here to ask questions and we arent very polite to people who dont know ---- about boostin.. Its initiation.. Now if you cant handle it, which it obviously shows you CANNOT, then we dont want you a part of the forum.. This is a rude and belligerent place where men speak there minds.. Not ------- honda-tech where if you tell someone that there carbon fiber cock piece is gay, you get banned. Here is a sticky with your name on it.. Look around this site.. Quit with your lame ass come backs... While your wondering how much boost you can run.. Guys on here have been enjoying 10 psi for years.

You suck at the internet and life.

Re: HOW MUCH BOOST CAN I RUN?
 

Whats funny is the guy claims to own a 550 hp eclipse, and "knows what hes talking about", i think he said 26 or so clutches, 7 engines and 5 trannies or so later... bwahahaha

Re: HOW MUCH BOOST CAN I RUN?
 

i just saw that thread too.....this kid is so full of ----

Re: HOW MUCH BOOST CAN I RUN?
 

I thought you knew we used dsms as parts cars

Re: HOW MUCH BOOST CAN I RUN?
 

So let's see some dyno numbers/videos

Who built the car for you?

Re: HOW MUCH BOOST CAN I RUN?
 

Well then, I will politely say this to you...you sir, are a retard. So you supposedly have this dsm making all this power, but you still don't grasp the concept of forced induction and it's limits in the first place.
How's this for a scenario? Maybe if you researched the hp limits of the engine FIRST it will then lead to your conclusion of how many psi to run to achieve "x" cfm flow to meet said required hp level. So you don't think you can run a 14b over 9psi on your little c/r d15? I laugh in your face. My old stock z6 motor enjoyed 14psi from a 14b on a daily basis, my old LS/14b enjoyed well into the 19psi range before it bit the dust, and just recently my b16 enjoyed 10-12psi for the short while I had the turbo on there. Not to mention that motor saw 13psi from a precision sc61 unit to the tune of 317whp for a quick one. To ask how many psi to run is like asking how many times you are going to prove you know very little about this type of stuff and embaress yourself. ;)

You've got a long way to go, noob. ::)

Re: HOW MUCH BOOST CAN I RUN?
 

That was rude. Listen, you never explained yourself. You said Y8 pistons, so we assume it's in a....Y8, which it's not it was in a D15 which also means it needed bored/honed to fit a larger piston. In turn, it is NOT a normal set-up. You mentioned two different engine codes and expected us to understand what you want exactly. Where you are at is going to be fine and the rods are far to small to really push it much further.


JP

Re: HOW MUCH BOOST CAN I RUN?
 

Bore is the same from the d15's to d16's...stroke is different. I know personally that d15 pistons will fit a d16 bore.

Re: HOW MUCH BOOST CAN I RUN?
 

I was wondering that as I typed it, but didn't know for sure. Still not a typical style set-up. Thanks for clarification though. ;) ;D Where does the other .1L come into play then? Do they only fit because the cylinder walls aren't perfectly OEM spec and a little looser? Just curious.


JP

Re: HOW MUCH BOOST CAN I RUN?
 

It's done the same way as say a b16 compared to a b17...longer stroke creates more displacement, even though they both have the same block/head.

Around 185 or so you will start snapping the thins rods of a d15.

Re: HOW MUCH BOOST CAN I RUN?
 

Ahhhhh, w0rd. Thanks man. :thumbup:

Re: HOW MUCH BOOST CAN I RUN?
 

Slo, don't help the faggot noob, kthx.

Re: HOW MUCH BOOST CAN I RUN?
 

What...you think you're the first person to do this? LOL ---- man, I was doing d-series piston swaps when you were still wetting your bed :P
Correct. Less compression will allow much greater boost pressures with an advanced timing curve, but only up to a point. D-series motors are picky with timing, and they don't tend to like a great amount of it.

Re: HOW MUCH BOOST CAN I RUN?
 

WHY IN THE ---- DO YOU TYPE SO DAMN RETARDED.

ya use okkkkkk and ahahahaha and hahahahahayouve been typing like that all over this site and it's verrrrrryyyyyyy fuuuuccckkkinin rettttaaaaarded. in my opinion you are the most retarded person i've seen on the net and it gets pretty retarded on the net. go to hell noob >:D, oh wait your from canadia.

Re: HOW MUCH BOOST CAN I RUN?

Re: HOW MUCH BOOST CAN I RUN?
