Too much money IMO though but hey my crack habit is at least 1000 a month so what am I talkin' about?!!

The thing to remember is that the GT-28 turbo's we are using in our kits are ball bearing turbo's not the older shaft styel turbo's. SO whilst they are also capable of 350hp , they produce boost at very low rpm levels compared ot other similiar hp sized turbo's, are designed for lower oil pressures and have a much lower heat factor under boost compression so that the intercoolers become more effective.
The non ball bearing T-25 and T-28 turbo's are fine and can be used instead but are not anywhere near as efficient.
And remember our kit comes with larger injectors, fuel pressure egulators and other additions as well. They aer now also available with pre built intercoolers and pipnig as well.

oh wow great to hear about the intercooler and piping mitsiman...that was pretty much the only downfall with your kit. but now that you have piping with a tubular manifold...thats awesome.

Ball bearing, man those are great!!!! At what RPM do they make full boost? I'm sure its a pretty quick spooler, so this is a Garret t-28 that comes with your kit? Is it the big or small. I wasnt sure if they had made a "big" T with ball bearings
let me know!!! Even tho the t25 comes with ball bearings now does it still tend to heat up the air at high rpms, same as the shaft style, at around 6k?

The GT series of turbo's come with qutie a few different specs so here is our interpretation and our specs
GT-25 turbo rated to 200 - 220hp suit 1.5 up to 15 psi boost, 1.8 up to 12 psi boost, 2.0 up to 8 psi boost. Boosting at approx 1500 rpm upwards.
GT-28 Turbo rated from 200 - 300hp suit 1.8 8 psi + 2.0 7 psi +. Boosting from 2000 rpm upwards.
GT-25R Turbo rated from 300hp + suit modified 1.8 or 2.o 12 psi + boosting from 2500 rpm upwards.
We only use ball bearing turbo systems on all our cars.
