14b sohc question

hi, so i decided to turbo my motor but i was going to wait till spring/summer. i came across a 14b turbo with exhaust manifold for 200$. now my question is, how is that turbo. i know its of a talon. btw i dont really know too much about turbo's. the guy says that the turbo comes with internal wastegate. also i got a d16z6 and i figured im just gonna run low boost till summer when i will get some more money to build the motor. i was thinking about 5-6psi since i know stock runs 7psi max without any work and i just want to be on a safe side. [correct me if im wrong]. what you guys think? oh and i asked about the turbo whether its got any play to the shaft or not, and he says no. what should i look for in the turbo to see whether its good or not???

by saying fins are good, meaning not warped/cracked etc?
also cant you adjust the preassure with the wastegate? meaning drop below 7?
also im not doing injectors/fuel pump yet so i dont think that it will get 7psi will it? the thing is i want to ride on this motor atleast till may or so.

ya the 14b's run like 7-8psi stock, you can't turn it down and lower than that, you can only use a boost controller to turn UP the boost.

I wouldn't run stock injectors and stock fuel pump on ANY amount of boost, for longer than a day until you can get it tuned. Use at least 440cc injectors and a walbro 255lph fuel pump.

A 14b on a d16z6 will be ok. It'll build boost quickly, but start dropping off up past 5500-6000rpms. You can use an electronic boost controller to keep the boost levels at a steady psi at all rpms, but if you don't wanna spend the money on a good turbo setup/injectors/fuel pump, I doubt you'll wanna buy a good boost controller (no offense).

Everyone wants to boost on a budget, they do, then build something better shortly after boosting their cars in the first place. I've seen it time and time again. You're better off doing it how you want it, the first time. Besides, theres a lot more to a turbo kit that just a manifold and turbo. You still need an intercooler, charge pipes, blow-off valve, oil feed and return lines, coolant feed and return lines, tapped oil pan for the oil return, injectors, fuel pump, chipped obd1 ecu, tuning, boost gauge, couplers and clamps, and some misc vacuum tee's and lines.

so i figured this, ill buy the turbo, and then work like mad over christmas break,save up and start getting all the parts. by spring ill have everything and then everything will go in at the same time. also zeeman how much would you chip/tune my ecu for? and all the stuff you listed that i need, if i do it on the budget [not cheapest parts but cheapest reliable parts] how much am i looking to spend? dont really wanna go more than 1500$. i figured i can get ebay piping, since its just a pipe. used intercooler. what do you think?

$1500 would be tight, you'll have to buy used parts. If you're doing ALL of the work yourself (including chipping/tuning/install) you could do it for that much, otherwise, chances are you'll go over your budget. Boosting a car (like doing a swap) can nickle and dime you to death.

what's tuning cost these days? I'm working on a similar build and I'll be doing the work aside from that.

People have told me any where from $300-1000+ depending on where they went, who tuned it and how long it took.

yay so i got myself a turbo with manifold today. no shaft play, no cracks/chips. the fins spin smooth. now just last question [probably not, ill have more to come later but just bear with me] about the injectors, if i was to get 440cc injectors can i use stock fuel rails, or i have to buy new ones? because i saw 450cc injectors for sale on classified of a talon, and was wondering if i was to get those can they mount up to stock rails?

hmm the only thing is, the dsm injectors are peak & hold and civic ones are saturated. sorry cant do too much re-search since im at home but i was reading somewhere that you cant interchange them. is that true?

yeah i just saw that part

'Now alot of people are installing these DSM injectors (hold & peak) into their 5g Civics that are (saturated) style injector systems. You will have to install a factory Honda Injector resistor box, or you can do it this method. First you will need to cut open the stock wiring harness to get a closer look at all the wires.'

I would say about half of the cars I tune use DSM 450cc injectors. They fit the fuel rail without any mods and fit into the intake manifold without any mods. You will however have to use a resistor box if you using them in a 92-00 civic. If you're using them in a 92-95 civic, there is a way you can install the box without even having to cut any of the factory wiring harness and is essentially plug and play.

I'm in the same boat. In my collection of parts for my build I picked up DSM 450's. I need to find the resistor box, along with a few other parts still.

Martin I know someone who after hearing I'm building a turbo set up he offered me a set of 450 dsm's for $50 if you want them let me know I can grab those for you.

you can get them off a 88-91 civic, a 90-91 integra and a 90-93 accord iirc, dustin.

ya, get one from a yard or something, b/c if you get one with both sides of the electrical connector you can make an incredibly clean/simple install, where you can put everything back to stock very easily as well. I'll find the link and post it up, its what I did in my car and it looks OEM.
