I've researched many many turbos and think that I could make several of them work, but maybe not to their full potential. I want to know what you have seen/done to help out the guys looking to make strong numbers.

Personally, I'm shooting for 650hp on race gas.

My current setup:

AEBS Sleeved GSR @ 81.5mm
JE 10:1's
Crower Rods
Victor X IM
Crower Springs/Retainers
ITR Cams
Turbosmart T3 Topmount
Precision 1000's (maybe upgrading do ID2000's)

Lots of other parts going on the build, but none that play into the turbo choice so they arent posted.


Regarding Turbos: Keeping in mind I'm looking for a solid T3 Turbo capable of 650hp.


Precision S6262SC:
.83AR

Bullseye S366
.88 AR

Garett GT3582
1.06 AR


Please give me any positive or negative feedback you may have had from these three turbos. I will continue to post graphs that I have found during my research until I find enough facts to make a good decision. I dont want to waste time on the wrong turbo after I've come this far.

Thanks for all of your feedback HT.

 

HTA gt35r with a .82 t3 3 inch vband exhaust housing
this turbo has made 700whp on awd evos. i have this turbo on my stock 2.0 evo and i get full boost at 4k rpm

 

The T3 S366 can do that VERY Easily, and with less boost than any HTA GT3582R, considering its TRUE extended tip compressor wheel, larger exhaust wheel, and less cost at $1350 vs. $1700

The video shown below is a T4 turbine housing, but the T3 can use the same exhaust wheel to fit in a .70A/R v-band. That is actually a standard S366, and not the S366XL, but that can be had for a minimal charge.

I would use the S362/366 or 6262. They will all make power very easily and spool fairly decent.

 

Awesome power #'s. what type of compression are you seeing in your evo?
Just curious how this will spool with a 10:0 B series.

 

Great Numbers and spool time is amazing.

Any suggestion on vendors? (PM if that's not ok on forum)

Thanks again guys.

 

S366 all the way!! we made that on a similar setup for a local customer. Its amazing how well that turbo works.

 

PM'd

 

What happened man? You're not providing much help getting the Precision billet wheel smaller turbo bandwagon rolling! LOL. . . What were they we were discussing, sc5857 and 6057, or something like that? Oh well, off topic for this thread.

 

t3/67

 

PTE 6262, 6265, and 6765 would all be capable t3 turbos of that power level.

I am sure the Borg Warner listed would do it as well I just dont have as much familarity with those as I do Precision.

BTW something to consider is that Evo's and 4g63 powered cars are not the same as a honda motor for comparison when you see all these big numbers. Alot of the record numbers or close to it on t3 turbos are done as boost levels you would not be able to reach. The turbo will not make that much boost on our motors. Some of these guys (have a friend who is one of them) are running upward of 45 psi on kill to make that monster number. Least from what I have seen this seems to be the case.

 

Isn't that just a function of the Honda head, intake, and good exhaust manifold flowing extremely well? Assuming so, similar horsepower should be attainable with those turbos, just at a lower boost level. After all, boost pressure is just a buildup of unexpended flow volume. So to speak. . .

 

haha

Well, I just told him which of the turbos he listed would work. The 5857 and 6057 would do the job for 650hp, but nearing 700 is where I would say the safer limit is.

 

That seems to be accurate from what I seen on here or in my own car, most well setup hondas see great power per pound so to say no doubt because of the better more efficient head or whatnot. Running a slightly lesser boost but making more power per pound obviously does level the playing field. Also vs per say an awd car we would have alot less drivetrain loss to deal with.

Just my point was more the 4g guys are pushing to extreme presure levels by our standards to make these crazy power numbers on t3 housed turbos. So a comparison between the us and them is not as easy as saying, well they make this so you should be able to do that too in a similar way. Alot more plays into it like your post above gets into.

Basically I may have worded it poorly but my intend point is really simply. I just didnt want him to see an evo dyno showing whatever huge big #'s on a e98/ q16 car with 46-50 psi and think that it would take similar conditions to do it on a honda. The honda can make big power no doubt, but the conditions will have marked differences from that of the 4g guys.

 

T3 t67 ho. With .82 or 1.06 hot side.

 

it depends on if its going to be track only car.........so what is the car going to be used for? we can give a better answer with that information

 

I intend it to be track only 99% of the time... probably 100% but I'm that guy that didnt think he would ever have a track only car so I'm clinging to my 1%

I'm not as concerned with HP as I am 1/4 mile times, but I know it takes power to get down the track.

 

Precision pt67 or the billet 65/67 will get you there with no problem.

 

that is a great turbo, use one myself.
but there are better purposed turbos. i think it is a little finicky. but it does work in my case.

 

get garrett.. hehe

 

T04ZR here. Love it....

Im partial to Garett precision offerings... Thought about a s366... Glad I didnt though...

 

Why is that? ANy bad experience with that turbo? I am about to get a S366, so please let us know if you had any bad experience with that turbo.

 

People are going to have bad experiences with ANY turbo, but it could be for a multitude of varying reasons. It doesn't mean the entire brand is bad. So try not to be overly conclusive of either Precision or Borg-Warner.

 

s366 is a good turbo. i almost bought that exact one. I dont feel like getting into a pissing match here. Lets just say the 67mm BB Garrett performed better on my setup in a couple aspects that mattered to me and prob wouldnt to you... Ive seen how those threads go and dont feel like getting involved in one like that....

bottom line is ya kinda got to do your research (hard data is better han someone steering you onto one fanboi bandwagon or another) and make your decision.


YOure not making a bad one at all.

 

^^ Good way of putting it. No pissing match indeed. In the end, over 66mm inducer is going to do the job. Let's concede to that..
