ls/vtec, bottom end fully built b18b except for stock sleeves, top end b16a w/ jdm type r cams and aftermarket springs & retainers. Here's the question. What can i expect if i max out my drag gen III turbo kit to 25psi on this setup on neptune? I would go ahead and change the manifold and turbo to something bigger and better, but i'm strapped for cash at this point. If what i have now can make me happy, then why change? Oh, here's my second question. Will i be able to push 25psi on pump gas? And i'm not sure of the turbo specs, but it's whatever's standard with the drag gen III turbo kits.

 

391.5 whp 258.9 ft lbs tq

funny......i know you guys hate this type of post, but i'm just not ready to spend a sh*t load of money on anther turbo manifold and turbo (and radiator i might add). i just wanna see what some of you guys think because i'm all about other people's opinions.......just trying to see if i'm just going the totally wrong route about this and i should just cringe up and spend more money........

 

anybody else?

 

If you arn't ready to spend a shitload of money on a new turbo and manifold, you arn't ready to spend a shitload of money rebuilding your motor and turbo when they both let go when you try and push 25 pounds of boost into the motor on pump gas.

 

well then what's the limits on 93 octane as far as boost? If i can push 350whp on pump gas with a huge turbo at like 12psi, then can't i push the same amount of hp on pump with a smaller turbo but at like 25psi? Not to mention, i don't have easy access to anything higher than 93 octane..........

 

i dont even know if your turbo will be any more effective at 25psi than it will be at 15psi if its the stock drag turbo.

why not? drag says it's good up to 26psi and the kit as a whole is good up to 450hp (of course, that's probably crank hp)

still didn't answer my question though.......but to add to your point, the drag turbo probably won't last too long at that type of pressure........

 

well i maxed out my DRAG turbo around 18psi..it just didnt want to make anymore power past that.

WOW, if you want specific info then @ least give specific info to get it. What compressor side (give us the map)? Don't believe much of what the manufacturers of these mass produced kits put on the specs for these things. And even with the map it would still be a guesstimate.

 

sorry, i don't know the specs on my turbo.......it's already installed and i can't really read it......not to mention when the shop ordered my kit they just told drag my setup and then i got what i got........THEY don't even know the specs of my turbo.......(not to mention, i'm still a turbo noob, sorry) Kit was ordered for b18b in a crx
