DAILY DRIVABLE BOOST FOR A B18C
STOCK B18C, DAILY DRIVER,RELIABLE BOOST? (and when i say reliable im mean being able to drive my car for the next couple years)

Re: DAILY DRIVABLE BOOST FOR A B18C (REWURKD)
Well, on a stock motor usually you want to keep it 8 psi and under (rule of thumb), but this also depends on which turbo and how well it is tuned. There are people on these boards that are pushing 300hp and even more on stock motors...so i guess you could say its very dependent on tuning and how much hp you are making.

What is your engine management setup? I would keep it at 6psi daily if your just using whatever came with your kit. Once you get it tuned i would bump it to 8 for daily driving and 10 for track days. Don't stay in boost for long periods of time No fifth gear redlines heh

Re: (Turbo E)
this is the best point to make. I could run 15psi daily but how many times during my drive to and from work am I going to even leave vacuum? I know guys who claim 30psi daily driven but do you think they get to 30psi during their daily errands?
The rule of thumb most people abide by with stock motors is 7-10psi. do the low end of the spectrum if you are running a fmu and the higher end is safer with reliable engine managment.

Re: (phiberoptik)
I'm superized mods did not lock this very common question or that other members did not flame you yet. Well it's going to run into a lot of factors. I'm in the same situation as you. Stock B18c1 come with a 10.3cr (correct me if I'm wrong please)
Baically a good rule of thum stock motors can handle on a daily driving consistanly 5-7psi.
now with that said there are factors in there that play a huge role such as :
1) turbo size.... this give us a good idea of when you reach full boost or how often your motor will reach boost.
2) fuel managment..... what are you going to be using? injector, fuel pump ?
3) what is the average climate/temp?
4) what gas to you have access too (87,89,91,92,93 and some places even have 94)
those would your main things to factor in for a SIMPLE boosted daily driven car.
now back to turbo size. you could get a larger turbo like a t3t4 that generally gets full spool of 7psi at about 3800-3900rpms under heavy load.
Or you can get a smaller turbo like a t28 that spools at 7psi around 3,100-3,200rpms.
......... Now obiviousely your going to see boost earler on the t28 then you would a t3t4. So take for example same car, same motor, tune very well, same driver. becaue the t28 gets faster spool you will see FREQUENCY of boost.
but at the same time if you were driving the t3t4 setup you nessary will see parital boost before you shift .... BUT when you do hit full boost the QUANITY of "boost" will be more meaning more wear/tear on the motor.
compare this to say........ hitting your fist aginist the wall at (say T28= 5mph) frequently once every 10sec......
the try hitting your fist aginst the wall at a say (t3t4= 9mph) frequenlty once every 15sec...........
Frequency would be realted to how often you see boost & mph would be the force excerted on the motor......it does not hurt at all but does wear down your skin, bones, cartialge and overall streght & power of your hands over time. NOT trying to be sick or anything but kinda like sex..... longer lasting yet satifying or bigger bang and quicker end....... I hope you get the idea. Your motor will wear down faster with boost wheather it be 1 year or 5 years is CONTROLABLE to you on how you drive & take care of it. I hope i don't get flamed for this analogy.
But also remember that boost in psi is not equal so 7psi on a t3t4 is not equal to 7psi on the t28. So both motors boosting at 7psi the motor t3t4 one would crap out 1st simply because it is making taking more air, causing more pressure & wear/tear on the pistons/rings, and making more power.
personally i have a small turbo on my gsr so i can take it up to 12 to 16psi..... that may sound crazy but with my turbo it would be equalivant to boosting 10 to 13psi with a t3t4..... get what i'm saying.

Re: (Charlie Moua)
THanks Charlie for all the great info.
I would like to say that I am new to H-T (check the post totals) so I apologize for a very common question . But much thanks for the helpful replies

Re: (Pfieffdog)
my car barely sees full boost 95% of the time i drive it. Sometimes, it hit 3-4 lbs when i need a little power. Unless you shift at 8k or race on every stop sign, you will be fine

LOL i wish i had discipline i drive mine @ 15lbs everytime i drive it (which is NOT daily )

yes that is prime example of what i was talking about. Kudos to you brryder!
The advatage to having a longer spool time (not lag.. lag & spool time is different)
is that you can drive very normal ..let's say no more than 50% wot, and never see boost depending when you shift that is, simply because if he shifts at 3k @ 50-60% WOT and he reaches full boost at 3500rpms during WOT..... there would be no way he would build a lot of additional boost.
understand?
with a small turbo on a gsr you have VERY LITTLE room/rpm to play with and controling if your motors sees boost or not is near impossible with a tiny turbo....
the possible is still there to control it......but you would not be driving your normal driving patters.

Re: (InTeGrA B18b1)
if u drive normally and dont rape your car, you should last for a couple years. it all depends on your driving style. if u wanna hit full boost in every year, then u might as well get AAA membership

no entirely....
more like this... same car, tune well, same driver, same psi (7psi):
Smaller turbo/t25:
*faster spool becuase needs less load
*power is easyer to access when needed
*more USABLE overall powerband/curve
*less shock to the entire motor/tranny when you hit full boost cause you already near instanly build boost at the earlyer RPM
-cause of early power your motor will more FREQUENTLY see additional pressure. but keep in mind psi on t25 does not eqaul same psi on t3t4.
-cause of smaller turbo you have to boost more PSI to make as much as the same motor would with a larger turbo @ technically speaking same psi.
-cause of early power it needs more gas, so you tipcally your injectors will dump more gas as you build boost per PSI = lower gas mileage daily driven
<U>Larger turbo/t3t4</U>
*larger turbo require much more LOAD or pressure of exhaust flow to contantly create boost. There for you could easly control when and how you use your boost in daily driving. Exp: b18c1 + t3t4, daily driving at only 50% WOT shifting at 2,900-3,200rpms you should not see boost at all that day. BUT shifting at 2,900-3,200rpms at 90% wot you might see 3-4-5psi of 7psi.... so not full boost but none the less boost.....
*advatage of TOPEND POWER
*cause in daily driving you are not contanly seeing boost, you technically should see very similar MPG as any NA b18c1 would (granted tuning is done correctly) .... so better daily driving gas mileage
-MUCH more shock the the motor when you instanly hit full boost.
-larger turbo make more power period.... and they will kill your motor faster period (again granted same driver)
hope that helps.
If this is your daily driver and you want to keep it safe, reliable, long lasting, not too much complications and simple so that you can still kill v6 and hang with all v8 on the STREET ..... food for thought.... why do fatory turbocharged cars come with smaller turbos that the motor itself can handle?
could it be..... longtivity & reliablity of the motor.....
