I have a full greddy bolt on turbo kit in my 99 prelude
i was wondering if a bigger greddy turbo will fit that manifold
currently it's td 05/06 im looking into swtching bigger turbo in
but want to try the easiest way possible

 

most greddy turbos have a t25 flange, so u can use a 20g turbo with it.

 

Since you have Greddy Turbo Kit the best way you call Greddy Technician for help . That what I would do

 

ill ask some shops around and ill look into that 20g thing...

 

so what do you want a bigger turbo for? are you building the motor?

 

im going to...

 

although i have a friend on a stock block and head running 18 psi.. runs perfectly fine... but he's tuned... he's put about 10k on it and no problems.. maybe it was tuned right
