I just sold my old turbo and need a new one so what do you guys think would be a good one? I am thinking of a T3 60-1 but I don't know if I should get a .63ar or a .82ar. I am going to drive it on the street but I am not to concerned about street use, just the odd race. I am more concerned about good times at the track. I will be boosting between 20-25psi at the track, and 15psi on the street.

go with the .82 ar, that psi should work well that big of a turbo.

If you drive the car on the street at least go with the .63a/r housing. I couldnt get my .63a/r to barely spool up on my stock internal b16a. I made full boost on 8psi at 6,000rpm with 3" dp, 3" exhaust, no cat, boost controller, etc. Its a laggy turbo that just isnt fun to drive on a 1.6 displacement. Also, let it be noted that with the 60-1 you will have to be boosting at least 12psi to make it efficient over the to4e wheels.

My recommendation for a turbo would be the t3/t40e, 60trim, stage 3 exhaust blade with a .63a/r housing. You will make full boost by 5,500rpm (25psi), and have a decent turbo on the street. Its very hard to max out the 60trim compressor blade. If you look at the compressor map you would still be efficent at 25-26lbs of boost.

My last bit of advice is that i just downsized from a 60-1 to a 60 trim to4e. The 60-1 was on my last gsr engine swap. I made full boost at 5,500-6,000rpm (14-15lbs) and shifted at 8,500rpm. Its was a very quick turbo, but it didnt really start to pull till after i boosted past 12psi (hint it wasnt efficient). I plan on daily driving my car, not letting it sit for months like it has been previously. A larger turbo will give you more reliability problems ten fold. Choice is yours on what turbo you go with, but the 60 trim with the .63a/r will support 450whp.

I also have to ask, why is 25psi your specific goal? You should ask yourself what horsepower level do i need to run x time in the 1/4 mile. If you actually drive the car on the street daily, a huge turbo is going to get old quick.

You didn't hit full boost on the b16 with the .63 a/r turbine until 6000?? That is the turbo I got...and I am planning on boosting a b16...

boosted hybrid

Well "full boost" at 5,500rpm but it didnt actually start to pull hard till a bit over 6,000rpm. It was the most worthless powerband i have ever felt. If T-sohctec or sweet is around on here ask them, they rode in the car. It was fast no doubt, but it felt like a drag racing powerband.

HXMan

Crap.

I wish I new what the a/r was on the turbo that came with my drag 3 kit...I liked that on my old b16...

boosted hybrid

Your kit probably came with the 54 trim t3/to4b with a .48a/r i believe. If you wanted a badass street turbo then go with the 60 trim t3/t4oe with a .63a/r. This is what i am going with on my 2.0 gsr block, i switched it out from the 60-1 t3/.82a/r. I just decided that the turbo was retarded to try and use on the street. I'd rather have a more useable powerband (more area under the curve) than a dyno queen.

I say go with the t3 60-1 with .82 a/r. It will provide plenty of air at the track and you will have great top end.

With a build b16 setup you should tune it to a bar and just run that daily, on 93 octane. If you tune it right there won't be anything to worry about. The 84mm sizing helps a lot too, get a full 3" and wrap your downpipe, you should see a bar between 5k-5300 rpm.

Very, very rarely do people downgrade the size of their turbo rather than upgrade. Its up to you though. Figure out your power and time goals, go from there.

precision turbo sc series depending on your hp goals!!! I would run an sc60 which is similar to a 60-1 but will have more power and will be very streetable with a .63 rear.

hybrid901

I have a 60-1 from majestic turbo but it only has a 3" inlet. It also have a .63 exhaust housing with a stage 3 wheel. I get full boost around 4500rpm (18psi) but it really takes off at 6k also. Is my turbo really a 60-1 or it just a different one? What kinda whp can mine produce? Btw I have a b18c1 81.5mm with 9:6:1 comp.

You wont get a b16a to spool up a .82a/r housing very good at all. If you drive on the street the powerband is going to suck. I just dont believe some of the "full boost" times people claim on this site. I have never seen good spool up even on a gsr engine with the .82a/r housing. Heck, i am skeptical about running the .82a/r housing on my t04e i just bought with my 2.0L block with headwork.

boosted hybrid

I'd just like to add that the .63a/r housing is very capable of making some serious power, probably between 450-500whp on the standard t04e 60 trim wheel around 20-22psi. There is an old post by ninesecrx of a gsr engine they built and was running a 54 trim compressor and .63a/r housing. It made a bit over 450whp and around 340 ftlbs of torque at 18psi on race gas, yet still made full boost at 5,000rpm. That should say how the honda scene overrates turbo sizing...

MotorMatrix.com

dont forget it is an 84mm b16. with an .82 rear you should see boost by 5500 and if you are into the street racing scene its a good choice cause you wont burn tires as much. But i think this guy is into the track and not street so i would suggest the .63.

HXMan

That is the exact turbo I bought for a b16. Oh well, guess I will see how it works this summer.

I didn't think the drag kit had a .48 ar turbine. It seemed bigger then that..plus I was under the impression that a .48 would run out of steem on a b series engine above 7000 rpms. On one dyno run I made peak HP at 8400 rpm with that turbo.

boosted hybrid

You might have had the .63a/r housing. The b16a kits usually come with the .48a/r housing.

Just to clarify the 60 trim and 60-1 are not the same compressor wheels.

Soon_2b_evil

well what about running a 2.0 running it up to about 9000rpm with a t3/t04e with a .82a/r housing?

my drag gen3 kit came with t3/t04b with .63a/r

boosted hybrid

For a street car that is retarded, for a track car with your shift points at or above 9,000rpm then that would work just fine. I dunno, i realized that you cannot put 400whp down on the street and 450whp is all you need to hit high 10's in a eg hatch with si gears.

I have a drag manifold and I am worried about the clearance issues with the 4" inlet on the t3 60-1 turbos. I was wondering about the hi-fi series and the power differences I expect to see...

boosted hybrid

You will have some major cutting with the .70a/r of the 60-1. The hifi will make you cut about the same amount as the turbo that came in the drag kit, possibly a little more.

The hifi 60-1 is 10% less efficient, also it doesnt flow 60lb/min its probably closer to 52 lb/min. If you are going to go with the hifi version, you might as well go with the 60 trim t3/to4e its a much more efficient compressor wheel. The 60-1 hifi isnt a very good choice IMO.

turborex

does anybody have any dyno numbers for a 60-1 hi-fi turbo?? And if so, what size?

turborex

If I were to get a bigger t3 60-1 with a hi-fi option, say a .82ar would that be a little better than a .63ar or should I just get a t3/t4???? My big problem is the clearance issues with the block from the manifold.
