the 60/63 garrett has a small efficiency range. its not a good turbo for your goals.

heres a map for 400hp


heres a map for 350



As you can see, its well into surgeline.. dont expect much from it.

Ditch it and have Shodan make you a silver surfer with a 58lb wheel

And youll need a larger intercooler.

Those sleeves don't look to good. What fuel will you be using? How about you tell us what you wasn't to, make, not ask us how much you'll make.

That's way enough for me. Is it also OK on low RPMS or totally dead. Is it streetable too ?

Well, that's how it was built. I was using this block atmospherically before without any problems, it's re-honed and put turbo pistons now.

sleeves are Turkish-made. Some people use it around 400 hp without any problems. Of course I would like original dartons but this thing was built before I knew anything about turbo Hondas. Maybe next time

My turbo is NOT Garrett 60-1 by the way..

My fuel is 95 OCT pump gas. I just wanted to know how much will this thing make with this configuration, and since I'm still learning, I need to listen to advices.

Why do people do builds and not know what power they should be making out of it? Just asking but I think that's the FIRST thing you should know.

Those must be old darton mids....i have them on my build they have much more hole in the flange. I know mine were newer ones with the phosphate coating.

Also i think he is trying to say t3.t4oe 60 trim. Thats the turbo i have we have similar set-ups...im 410whp at 20psi with gsr cams....You can exect 430-440 with good cams. I would think you may have slighly more with top mount as far as peak hp, I wouldnt have gotten a top mount with this turbo tho...

On street don't need 18 psi it just spin tires , I turn down to 10 psi for the street and ran on the track on 10 psi w/slick 12.2@116. on the low rpm t3/t4 spool pretty quick. very streetable

what turbo can you advice ?
I don't have many options but the turbo company can build it I guess if you give me the exact tech specs.

actually that's true.

when reading people's thoughts, I decided maybe the goal can be a streetable 350whp..
