What is the best sized turbo for a B16?

Quick Spooling is a must!

I'm guessing most people are going to say T3/T04e

Is there anything quicker, better?

The best would be the 60-1 that will give you huge power at small psi but major lag. The best for quick spool would be the t3 but for power and good spool time it would be the t3,4e trim. Ball bearing also helping in taking the lag away!

I'm runing a t3t4oe (.57/.63) an i love it.
The turbo spools pretty quick and makes lots of power.
I had a strait t-3 but it was to small for my engine.....

manifold design also helps in spooling a turbo. basically, the smaller the turbo the quicker is spools. you wont have **** for power up top though. you could get a gt 15 and be making boost at idle if you wanted, but that sounds like a stupid idea huh

I was thinking about a straight T3, but b16hybrid, you said it was too small for the b16? So if I had an engine that redlined at lets say 6000 rpm a straight T3 would work, but with the high revving b16, a t3/t4 is the best pick?

Hmmm. I guess to each his own, but my friend is looking for a buyer for his T3/T4. He's switching out to a T3 because the other is just too big for his B16A2 setup (at 7 psi), and I'm inclined to agree. IMO, most boosted hondas are running such low psi that the majority of the turbos on them are way oversized and under-utilized. A T3 can make well in excess of 300 whp *efficiently*. That's more than a B16 can handle unless it's built. So why go with a bigger, less efficient turbo? Unless you're building the motor...

the t-3 I had started dropping off above 5,500rpm so imo it was to small for my engine.I have since switched to the t3t4 and it makes boost up to redline and pulls harder then the t3 ever did.At 7psi with the t3t4 it pulls as hard as the t-3 did making 10psi.I would rather run 7psi of boost then 10psi of boost making the same power.
I can only speak from experience with the two turbo's i had.If I were to recomend a turbo for someone it would be the t3t4 no questions asked, I also want to add that the spooling is very close to the strait t3, it takes a tad longer to reach full boost but when it does, it's well worth it..

Can I ask what trim and a/r you had with the t3 and what you have now? How much of a difference would that make? I want to spool as early as I possibly can, but I definatley don't want to loose power at redline. My original plan was a t3/t3 62 trim compressor & .6 housing with turbine trimmed at .63 & .82 housing

I figured if I got a bigger trim, it would flow as good as a t4 but spool faster. That's why I wondered what you ran and are now running.

I noticed in some earlier posts that others thought a t4 wasn't used to it's potential.

I'm going to turbo an internally stock b16 and only planning on running a safe 7psi. This is going to be street driven on a daily basis so I don't need a hugh turbo.

what about the T3/T4 57 trim with .63 A/R, just starting to look around, isn't that turbo a great compromise lag and power?

I really like mine

b16ahybrid

.42 compressor and .48 on exhaust.
Yeah a t4 would be overkill for only 7psi.
Look at some compressor maps to find a good match for your desired set-up, if you are only going low boost you don't want to go to large with the a/r.
60a/r would be more then enough

I am reading this very carefully...

Can you order a T3/T4 hybrid turbo from a company like IHI? Just curious... I'd like to get a ballbearing turbo but I don't really want a junkyard piece...

I'm not sure if you can order one from them. Sorry.
I got mine from cheapturbo.com but it's not a ball bearing turbo. They have really good prices and they can match a good turbo to your set-up.

Precision SC50 50 trim with a .63ar turbine.

This turbo will be perfect for you. Spools up fast, and will have very nice top end, and has the capability for 350-400hp.

i have the same size turbo on a stock b16.. its a lil laggy but not as bad as everyone makes it out to be.

15psi of fun

when is every body hitting full boost i have a t3t4 with a A/R.50 with a 63 trim i don't know what the hot side is and im not hitting 9psi tell 5000rpm

It could be my 2.1/5in down pipe to 2.1/4 exhaust, or the drag manifold or the long intercooler piping I don’t know I’m still new to this boost stuff

But when it boost it’s a lot of fun

We will see how it does!

I have a t3/t04b (the turbo that came with my Drag kit for my D16). I have recently purchased a B16a2 and plan to build up the bottom end for approx. 300+hp/185+tq or more. I would like to use the turbo I had for my D16 and put it on the B16. 1)because I would like to use this engine for autox/road race only(not much into 1/4 here) 2)because I am cheap and don't really need to super high hp/tq numbers.
Will I be able to obtain those numbers(300+hp/185-190tq) with the t3/t04b along with proper tuning on my Hondata?

maxim

bump for my question.

jdmcivicek

i am in a similar situation. i found a great kit with a t3 for my b16 and some people are sayin its too small, while others say its too big, and others say it works great.....im so lost

Why not find some compressor maps, run the numbers plot it, and figure out which one will work best for your PSI and motor.
