B16a turbo question
Ive been reading for a while and got a couple of questions...
Turbo on a B16a...
i was considering going with a sc50. I read that a .63ar will give more top end power with a sacrifice of low end.
The b16a is "apparantly' a bit sluggish down low and with this turbo, would probabl have a bit of lag and probably start to spool about 4000 rpm's
So what about going with a sc 50, .48a/r so it spools up faster>?
Am i on the right track here, or am I way off.
Thanks for your patience guys

Re: B16a turbo question (drvfast)
My question is why choose .48 a/r over .63a/r... which is better for the street?
Also... when would the sc32 and sc34 start making boost on a b16a?

Re: B16a turbo question (B16B)
.48 a/r would spool faster but sacrifice top end. go with .63 getting full boost too fast on a b16 tranny will give you massive wheel spin and you wonr go anywhere. get a .63 and learn how to drive it.

Re: B16a turbo question (B00stedCoupe)
I didnt want to get into this because there is a great divide on opinions, but what if i used the ls tranny, b16a motor, and .48 a/r.. would that be a reasonable set-up?
Also.. how much of a sacrifice would i be making by choosing .48 over .63
where would the .48 stop making efficient boost,and where would the .63 start spooling

with an LS tranny and a .48 you will still roast tires down low.( probably not as bad as with the 16 tranny) but anyway.. you should NEVER change your tranny to an ls tranny just to compensate for wheelspin. until you at least tried the proper measures to fixing taction promblems( lsd, traction bars tires and suspension)
anyway I still say .63 a/r you seem to have a major misconception of Lag.. while the .63 is taking a little bit longer to rach full boost.. it is still putting down enough power to roast the tires down low. and will pull significantly harder up top once full boost is acheaved... with a .48 a/r down low you will also roast tires but roast them harder (making you slower)while spooling. reach full boost quicker. but not pull as hard up top
if u wanna pull as hard as possible with that turbo from 40-100mph choose .48 if u wanna pull hard from 40-130 get .63

Re: B16a turbo question (B00stedCoupe)
I am actually figuring out a few different custom geared transmissions to make it a better set-up. Included will be an LSD. Im thinking of taking the 3rd and 4th from an LS tranny, with the 4.269 FD, but keeping the LSD diff and everthing else from the b16. This will go on the motor regardless of which turbo i go with.
you seem to have a major misconception of Lag..
No doubt, I realize that, and that is why im asking...
Everyone with turbo's around my area is very secretive and will not share any info they have. Plus I have not been able to drive any turbo set-ups. All i know is I want to make the power with turbo. Im not going for looks, or "oh it sounds cool with BOV" . I want to make real power, not rice power.
Ok, so if i go .63 a/r, which is a better for the compressor side?
sc32,sc34, sc50 or someother one i dont know about?
Thanks again for your patience guys

Re: B16a turbo question (B16B)
Dont know about ur plans but I have a t3/to4e turbo..not sure of the trim...came with the old stage 2 revhard kit. I plan on getting a sc61. I seemed to have reached about as far as I can with this turbo. I am at 15psi and with a 61 I will be making the same power at a lot less boost. If you plan on going with 350 + hp I would get a larger size turbo. As far as the tranny, you may have the right idea. For the track the b16 is pretty good cause of the close gears but on the open stretch, you get owned by longer gears of the other trannys. I have been debating on what to do with my b16 tranny. If you makes some changes post up your opinions on them.

an sc50 with a .63 AR is an awesome setup. The best map I have ever seen was for a t3/04e .54 trim. The B16 makes enough flow that it is suggested to be mated with a .63 AR.

Re: B16a turbo question (B00stedCoupe)
well... looking in the neighborhood of 300-350 whp with hondata tuning for right now. I will be building another b16 bottom end with rods and pistons once i have more money, then I can boost higher. So I do want a turbo that has capability of making power now, and when i upgrade my internals and boost a bit more.

Re: B16a turbo question (B00stedCoupe)
whatever psi generates the power i want. if i can make the power at 9 pounds... bonus... but if i make the power at 15psi...oh well.. it still makes the power. Im kinda swaying towards the SC34 now. a little lag never killed anyone
