I need a 20b to build would like to to be stock but will be ok if already ported i plan on bridge porting it
and using a very large turbo gt47-80 or so. i need one asap i would get a clip but dont need all the extra parts. and no use spending 4k on a clip when i can buy a blown one and use the extra cash on the build


thanks
Matt

 

I got 3 - but freight might kill it!

GT4780 isnt really a big turbo for a 20b.... I wouldnt look at anything smaller than a GT4788.

 

what turbo would you suggest if i went bigger than a gt47-88

 

It actually really depends a lot on its use. The GT4780 would be an awesome street turbo, but too small for a drag car.

 

yeah it needs to be kinda streetable but its mainly going to be towed be kinda a highway racer / show and dyno car

 

Sounds like a very interesting project.
