The only two GT-K s that would match that are the GT-K 650 and GT-K 850 although the 650 would be at its limits there. I would recommend the GT-K 850 for this given your requested boost threshold.

ah ok the GTK 850. did you know when the boost starts? hope not over 4000 RPM ?

Its tough to say as that would depend mostly on the exhaust flow produced by your motor which would be a byproduct of the Ve of the motor, cam profile, manifold design, etc..

yes o know ... did you know about some calculotars ? to compute the engine VE ? the cams are 270/270 with 110 overlap and the manifold is a custom trust axhauste manifold (see in the picture)

thanks ... many many

Considering this will be a custom race motor you may need to go with a custom turbo setup and not one of the standard GT-K models. The S trim turbine that normally comes with the GT-K 850 is rather large so my concern is that your spool up may be a bit later then you would like. I'll see if one of the engineers at Turbonetics has a recommendation.

yes that is ok hope a can get help as fast possible ... because the season starts.

how i say i`m looking for the best turbo charger not only GTK serie. but the main thing is Ball bearing.

did you need some more ionformations about the engine ? if yes witch ?

again times many many thanks

If any turbo is an option I would look at doing the HP72 compressor section from the GT-K 850 and the F1 T4 P Trim turbine from the GT-K 650. It wouldn't have the ported compressor shroud like the GT-K units do but that is the best turbo I could recommend.
