Hey guys. This is my set up.
Sleeved Dart B16 bored to 82.5mm.
CP pistions 9:1
Either a topmount or Ram horn Manifold.
Edelbrock Victor X intake manifold bored to match 70MM Throttle body.
My intercooler is 31x11x5 i believe with 3 inch wide end tank opening.
Garret t3/t04E 57trim turbo.
I was planning to run ALL 3in intercooler piping. My buddies think its OVER kill? What are your opinions or what are you guys running? My goals are 450-500HP. Or will i be fine with this set up? Also Will this Turbo be maxing out if im trying to push 450-500HP?

 

Not positive, but I think that turbo is only good for around 400hp. That means it can't really flow enough air to take full advantage of 3" charge pipes. What connecting rods do you have? Your block should be good for atleast 600hp. If you had something like a gt35r, then yes, 3" intercooler coldside pipes would help.

 

i have 2.5 pipes and a gt35r and my b18 makes 510 at 20 psi with ease.

 

There is a chart that Schister66 uses to address air velocity w/ the appropriate charged pipes. 2.5 has been known for over 600whp.

 

check the FI faq, in there is a table on charge pipe and what the required size is for a given cfm.

 

^^ that was what i was referring to..thanks..

 

you dont need 3 to make 500whp..

Im JUST upgrading now that im going for 600-650
but before that, I just had the 2.5

 

2.5 in deff will work ive seen over 700hp with 2.5''.if you have a sleeved block and good set of rods just get a bigger turbo so you wount max it out

 

i have scat rods. Also do you guys think i will be maxing out my setup with this turbo? WIll i need to go bigger turbo? The previoous owner of this turbo made 423HP....

 

Not only is the piping over kill but so is the intercooler! How are you going to fit that behind the bumper? Or are you using it instead of a bumber? I made 475whp at 20 psi with the 60trim which is pretty much the same as the 57trim but that is pushing it.

 

i already test fitted it behind the bumper, ya it is massive lol...But you think my 57 trim is pushing it? because i don't want a turbo thats always running and maxing it when i drive it/race it etc.

 

abit wasted.. you have almost a fool proof block yet using t3/t4
go for the BW S258 or S300 series.. it way better.. you wont be maxing out any of those turbos...

BW256 is for me at the moment..D16 build though...

 

This one...?

Yup thats it. You will be pushing that 57 to the max to get 500whp

 

With a B16 and a 57 trim you can make 450ish but that is pushing it on pump gas anyways so if you want 450-500 to daily drive on pump gas then go with a bigger turbo. You can do it on E85 though but then its maxing the turbo.

 

The 500hp i was referring to was the theoretical limitation of the 57 trim as listed by Garrett. That's the most BHP that turbo will make...considering the friction loss in the car, i'd say 452whp is pretty good.

That turbo used as the example in the linked thread above was pretty much maxxed out. It was on 110oct fuel on a B16. I dont really recommend doing that if you're looking for longevity; however, it was a good example of a turbo with an output that was near it's theoretical limit. It just made things easier when figuring out flow rate in CFM...

I made 474 with the 60trim at 20psi. It was still making good power each time we raised the boost but we stopped there because I was on a 2.5bar MAP. If I had a 3bar I would have seen 500 I am sure of that. But it is a 60trim so that is about 25hp difference between them.

 

518hp 373tq on 3" piping and a t3/to4e .63ar at 18 psi dont give up man try it

 

The larger piping has less pressure drop. So using the 3in will put you at a lower spot on the compressor map. Use the piping that will put you closer to the maximum efficiency of the turbo.

I would do it.

 

???

 

sorry i wasn't clear with that statement. I don't want to run a turbo that im almost/or are maxing out, and then driving on it, because it won't last to long. But some are saying i will be maxing out this turbo, others say try it.


The guy who had this turbo before i did with this B16 Block at stock bore made 423HP. So i don't even know what i want to do now....Please input from anyone who is running this and can vouch i will be fine? i want longevity out of the turbo. so if it means getting a bigger turbo to make that power then be it! input guys thanks!

 

If you don't want to run a maxxed out turbocharger, you will have to go bigger than your 57 trim. It "can" make 450-475ish whp, but like everyone said, its pushing it. Go bigger

 

exactly what i was looking for.. thanks
