I'm thinking about turboing my b16b. I've been reading through tons of old posts, but i can't find anyone who's actually done it. Although I'm sure that there are plenty of turbo'd ITRs. So what do you guys reccomend for going turbo with high compression. I don't plan on using forged pistons or a thick head gasket anytime in the near future. I may be picking up this set up soon:

Garett T3 .42./.48 50 trim Turbo
Rank1Racing Short Tubular Manifold
TiAL 38mm 7psi Wastegate
2.5" Downpipe (recirc. wastegate, wideband ready)
JRC 6" Front Mount IC
2.5" Charge Piping w/ hose and T-bolt clamps
1g DSM BOV
dsm injectors

I plan on tuning the crap out of it with Neptune. I'd only be running 6-7psi. What do you guys thinks?

Is that a good sized turbo?

I'll definetly need a fuel pump too right?

D-t

I'd get a bigger turbo if I was you. But you might be fine if you only want 6-7 psi. But I hear boost is like crack. So eventually you might turn it up anyway.

B16b motors are high compression, so keeping everything stock is not going to be too turbo friendly. If you keep it at 7 psi and with good tune it should last, especially with that turbo.

Your setup looks pretty good. Oh also you do not need a fuel pump. Extra precaution though. So if you can shed out the $ then by all means do it.

The only thing like I said is the turbo, maybe upgrade to a 60 trim. 60/48 at least, or 60/63. Something with more top end because the b16b is a higher reving motor. Remember tuning is the key, and don't get happy with the boost controller. B16b's are high compression, and not cheap neither.

The B16B turbo is not a bad platform to turbo at all, despite its higher compression than the B16A. It is still well suited for boost as long as the auxillary equipment has been addressed. Even the Apexi Power FC (Which has a DIRECT application to the B16B) can be used to ensure good tuning for boost. But your injectors, pump, tuning and turbo choice will be key. What are the goals of your setup? If over 230whp, time to switch turbos to something a bit better.

Otherwise, it is a good possibility.

I was thinking a walbro 255 and either dsm 450s or RC 550s. Would the dsm injectors be alright?

230whp would be fine with me. I'm in CO so anything with boost will be better.

BTW- what do you mean "it's well suited for boost"? I'm trying to decide if I would be better off trying to sell the longblock and picking up a B18b or B16a. The problem is that it might not be possible to sell the longblock locally...

D-t

Your fine with the dsm 450's for now. Unless your gonna go for over 300+ which I doubt you would want to do on the stock block by what your saying.

The b18b has lower compression, but not that great of a head. It is a great motor to turbo as it is not really expensive and they make great power on the stock block . You'll make more power on the b16b though. But again it IS more expensive, and a little more of a headache in terms of if something goes wrong.

Just turbo the b16b, you'll be fine with the dsm injectors, get the pump, get to a reliable tuner, and all should be gravy. Again don't get too happy with the boost. You should be fine.

Yeah I figure the smaller turbo won't be too bad for this motor. It should give it good midrange, but what's the stock boost limit?

ccivic

I would try to pick up a bigger turbo especially with the high revving of the b16b.. even just a 60 trim t3 would be fine.

Boostfed

Ahem the B16B is only 10.8:1 CR so it is not EXTREMELY high, slightly higher than a Stock USDM ITR 10.6:1 and slightly lower than a JDM ITR 11:1 Just make sure to get a really good tune on it with compression that high, it is easy to detonate and break ring lands with the compression and low grade pump gas

Also agree get something with a .63 A/R also, good all around A/R especially for a high revving motor too

exactly

2-7offsuit

Well I'm getting a good deal on this turbo, so that's probably what I'll end up using. I'm more concerend with getting it it running good at low boost before I worry about upgrading the turbo. We only have 91 octane in CO, will that be alright with the appropriate tuning?

R-Lug

Don't let ppl tell you that the CTR motor has too high of compression for boost. That's BS. With a higher compression, you'll spool faster vs. using a thicker gasket and lower compression. 7lbs with high compression is equivalent to 9-10lbs on lower compression. If you get the right tuner, you shouldn't have a problem with tuning. High compression + boost =

Believe it

2-7offsuit

Is that what you're running? I'd like to see an actual setup.

GeeGee

there is nothing wrong with high compression, check out this dude

that should be a lil motivation for ya

Does anyone on here actually have a tubo'd b16b? I'd really just like some first hand feedback.

Yeah, I've seen that before. Sorry I should have been more clear. I'm looking for a set up with all stock internals, with the stock 10.8:1 compression.

2-7offsuit

How can I figure out what the stock boost limit is BEFORE it blows up?
