which hybrid do you recomend? 1752 or 1756

Hi!!

the spanish guy again!!

the title explain perfectly my dilema. i´m going to buy an hybrid gt1749 vb with a modified compressed turbine but i don't know which one, 52 mm or 56 mm.

i want 1,75-1,8 bar in a pd 150 with 60mm stright pipe and de-cat.

can the remapp open those turbos near 1800 rpm??

thanks a lot

Your going the wrong way. The exhaust side on 1749VB is so restrictive that the gain of the larger compressor would be minimal.

BTW why do you want to use so much boost? 1.5bar is enough for 200hp if the engine can breath well.

Hi! thanks for your answer.

actually my car have 70mg/rev IQ and 1,67bar presure @4000. with that numbers, the car is 450 NM at 2500 rpm and 204 cv at 3800 rpm and i am very happy!! the car is very fast but i'm afraid for turbo health.

searching information, i found that in UK and portugal, some people have this configuration to:

-fiability
-increase the boost (220 cv @ 4000)

my focus is 480 nm and 210 cv with safe boost.
