I was wondering if you guys could render some assistance in choosing a turbo for me please. My setup is:

CTR head
Stroked B16B with Eagle Rods and SRP/JE 9.7:1 Pistons
50mm Earcluff Ramhorn Manifold
32x12x3 Intercooler
2.5 Intercooler piping
HKS SSQ BOV with 50mm flange
38 mm external wastegate
3" exhaust
3" downpipe
Spec Stage 3 Clutch and Flywheel

etc


What would be the best spec turbo for me to get? Any suggestions on a specific turbo would be greatly appreciated.

 

You MUST tell us what you plan to do with the car. the parts in and of themselves are nice, but could be used in a variety of purposes. Are you looking into road racing? Drag racing? , Street/strip? Spirited street? Do you want to go journal or ball-bearing cartridge, what hp are you thinking of trying to acheive? Many people here will just give a thumbs up on their favorite choices without learning more about what YOU want to acheive, and only YOU can answer that question. Think about those points, and we can assist a bit more.

Sorry about that. It will be a daily driver but setup for the occasional drag racing. It doesn't matter whether its ball-bearing or journal bearing. I would like to get around 450whp if possible on race gas.

Good start. Another question. This one might not be as easy. HOW do you want the power? Don't just say "quick spool" like most people. Are you looking for a particular torqueband or powerband? What's your budget? 450whp on race gas is easy. I've one setup that can do 450whp on PUMP gas (93+) with good easy fitment.

You've got PM

 

I'm not sure. I am a noobie. Any help or suggestions would be appreciated. Thanks.

 

The Shodan will definately help you out...he's helped me before

I'm always willing to help, if you're willing to learn..

 

i think a gt28rs .83 would be a good combo

 

my set up is not too diff than urs except i havent done my internals and im using a 44mm wg, u might wanna use one too...
im using a gt3082r but ud be fine with even the gt3071r .82 a/r

 

i would shoot for 350-400whp with your b16b so you can have a nice powerband, hey 187 when does your gt3082r hit fullboost by?

im not running too much boost for now my motor's stock. i have a .4bar (i think thats 6psi rite?) spring so i reach that by 5k rpm after which it creeps to 7psi by 6.8k and 8psi by 8k... i chose the higher a/r on purpose to shift the power band into the high end, but if im on the throttle by 4k i feel the car taking off even tho it was only at 2.5psi... by 4.5k im at 4psi... i do plan to go 84mm when i sleeve so it should come on faster and i think kartel's motor is stroked so it should come on earlier especially if he uses the gt3071r (use it!)
i think ill be happy with 350-400whp as well and im hoping i can get that after i go to 84mm, same compression as now, but .6 bar spring.

 

There are many more options available to you than people will let on...if you want a fast spooling turbo that makes good power, you have more options than a Garrett GT-R series. Personally if i ever need that kind of range from a turbo, my next snail will without a doubt be a Borg Warner S256. It can compete with the GT30r series without missing a beat, but the 2 features i like about it are that 1. it isn't a BB CHRA meaning i dont need to run water lines (savings of about $150) and 2. If something ever were to happen, the S2xx series can be rebuilt...unlike the GT30r

we will see just how well they compete soon enough. Once we finish up a couple things around the shop here we will be doing the testing.

as of right now i would have to say the gt3076r would easily be the best turbo for the OP's application (may changed depending on out testing lol). we have used these time and time again on stock and built block hondas with excellent results. great powerband, reliablity, carries tq higher in the powerband than similar sized turbos.

also you said it was stroked? what crank are you using? a b18 crank...eagle....

 

^^ I've seen the testing that SLS did on GSR98's white hatch...i'm very impressed with the numbers the S256/258 made. They're still using it on the gold D series EG monster

 

Shoot I run a GT3076R twin scroll and I'm in love. Turbo spools faster than ever loving hell on my stroked b18C. I'm making 460whp on 15psi of boost as well, on my stock sleeves. Daily drove my car for four months until I picked up my RSX.

 

a GT35r would do deal good on that setup...

i had 507WHP on race gas
427 on pump

Stock sleeved B16a w/ pistons and rods

drove it everyday

No disrespect at all is intended here Mike, but please remember, don't think that you're the first to test these smaller BW units at all on Hondas. I'm glad that you want to "test", but there are a number of shops who have already tested and used some of the smaller BW series. Pure Tuning, Pande's performance, T1 Development, Speed Industry, Direct Performance, and several others to name a few. Some have posted on here, others haven't, but the information is there. Take a search gander, contact these shops and thier feedback and you can see other feedback on the smaller units already here on H-T, as well as the testing that you're going to perform to understand some of the nuances of some of these units. The GT3076R is great, don't get me wrong, but again, the OP still hasn't stated all of his needs yet. It would be derilict of us vendors and turbo specialists to just throw up a turbo choice without first finding out HIS needs more thoroughly. Let him get more into what he's trying to accomplish before just PUSHING another turbo.

i know his goals are 450whp, daily driven, occasional drag racing events. he said it doesnt matter if its ball bearing or journal bearing, he just wants the best one. thats enough information for me to make a suggestion. gt3076r with a .63 a/r housing. we have used this turbo on 75% of the local cars all with the same goals as the OP, and all those cars have had excellent success.

dont get me wrong, i dont think we are the first to use a s256 on a honda, nor did i say we were the first to test it. with that said i havent seen any other dyno charts, and i have searched. if this has been so tested by so many people where are the results. im just as interested to see the results as the rest, if you have a dyno chart/pressure plot or know someone who does, link them to me, i've looked and i cant find any.

 

Cool, you were looking it this OP more carefully. (though it seems you're using the same turbo that you have with about every other thread brought around lately.) I'll get some links and other data E-mailed to you. Don't be afraid to check out the other forums online to get additional feedback, don't just stay with Honda-tech.
