upgrading stock turbos

140k on my j-specs and still going very strong.

 

Whats the best value twin turbo replacement if you just want a like for like replacement and keep the car running under 1.2 bar max?

 

3 grand to replace stock toyota items seems steep....

What about slower spool up times and a loss of low end power associated with hybrids compared to j-spec ceramics? Also a lot of people on here say that hybrids have hit and miss build quality.

 

No experience myself, just what I have read on here...

I imagine spool up time wouldnt be very different if at all and it says you can run 1.4 bar through them!!:eyebrows:

 

Yep, but you would need supporting mods - bigger injectors, fuel pump, resistor pack and fuelling sorted through standalone ECU or SAFC etc....

 

I would want to run 1.2 bar tops on stock ECU and j-spec 440 injectors. Would these whifbitz turbos suit my needs?

As far as i know you can run that on j spec ceramics so i would think it would be fine?!
