Safe boost for a b16 on stock internals?
 

I just got my JDM b16a2 moter put in my 93 Del sol...

I am running stock internals...on a greddy stage 2 turbo kit...

Just curious on how much boost people have run safely on it....
Not lookin to take any risks...without upgrading fuel system
I am running 4 psi atm...seems to be running well..

thanks in advance

7-9psi should be fine. Keep it at 7 if it's daily.

You could probably go as high as 10 psi but that depends what shape your engine is in.

the engine is in mint condition, always take care of it....I think I am just gonna run it low boost till I get some things changed...Fuel rail, fuel pump and injectors....let me know if I am missin anything...I just wanna run 10 psi safetly and not have to worry about anything....

u won't know if an engine is mint condition by the way it is taken care of... do a compression test... and see if there's any leaking with a leakdown test... if all the compression are about the same and are not low like sh!t, and engine is clean no leak or excess burning... then you have a well-taken care of motor...

7psi for daily from what i've seen around posts/boards/threads...
right now... try to slap on some lsd and get some good tires for winter... build the internals later when you also have the $$$ for TUNING...

good call
thanks

i have a completely stock internaled b16-t and for a year i ran at 9psi and it wasnt enough, but it ran mint no problems. for the last half year or so i have been running 12.4 psi daily and still have zero problems. now im not saying go out and boost your car at 12psi but it can be done safely and still be a daily driver. i have a walbro 255L fuel pump and 550cc injectors. and a aeromotive fuel pressure regulator, so nothing serious fuel wise. The key that i tell everyone is all about tuning. tuning is everything so thats where i would spend more money, just do the basic stuff that i mentioned and spend some cash on tuning and u can have a fast stock b16-t.

thanks for the info...

Yes, tuning is KEY. But what you're saying is kind of misleading. It doesn't mean that you need to go out and buy a $1500 AEM standalone or even a pricey hondata system. You can just get your ecu chipped and setup for crome/uberdata, which is only about $150. Then they (your tuner) can just burn a custom program for you while on the dyno using a wideband o2, and it will be safe, reliable and fast.
IMO a good street tune (low throttle setting) is just as important as full throttle tuning, which is usually all you get when you pay a tuner to tune your car on the dyno. Having a solid tune will really help keep things safe and reliable, especially in partial throttle because realistically you spend most of the time in partial throttle.

ok, that makes alot more sense thanks

he pm'd me and i explained to him exactly what u just said lol i do run chips aswell.

stand alone management I guess lets you change when ever you want via a laptop I take it

yeah, but you can do the same thing with a chipped ecu, you just need an emprom burner, rom emulator, laptop w/crome, and a datalogging cable in order to do real time programming.

Just how b16turbohatch said "Just cause my motor is running 12.4psi, iam not saying to boost yours that high".
I have talked with people who run around 10psi stock motor and no pinging or problems.
On the other hand, you can find the same amount if not more people that have blown there motors running under 10psi.
You live and learn, get a wideband 02 and slowly turn up the boost until its to your liking.

along with the wideband o2 you might wanna grab an EGT. Also if you wanna just turn up the boost MAKE SURE you have a boost dependant ignition retard such as a MSD BTM, its also a feature in crome that you can adjust.

OEM fuel pumps are good up to 250whp (so I heard) so you don't need to change your pump if your going to be well under 250.

If you plan to be around 220.. i would get the pump and regulator just to be safe.

I have 450cc injectors and the OEM d16 pump will do just fine for my set-up.

But then again.. at 10psi i'll be around 215whp. So it's not the most fuel thristy motor.

Visit www.homemadeturbo.com check out the forums.. there is alot of info. on that site.

Also.. if you haven't changed your water pump/belt in a while.. i strongly recommend you do so

alright thanks
