none of the current sp turbo are bb yet they will have there BB turbos out soon thow.pwvr4 said:Well, Like I said in my other posts, I want to make at least 800rwhp and have the turbo easily capable of making a bit more. I read that the sp74 starts spooling around 3400rpm with a nice open exhuast. Is the turbo a BB? And the Sp73 says somewher elik 870rwhp max, is the spool on this better since its a bit smaller? It is smaller right? Ayiyaya... supras and there single turbos.
looks like an sp71 or 72 is what your looking at more, also smaller turbos do spool up a little faster .
SP71GTQ ($1275) This is the newest of the GT turbo technology. The compressor wheel is a one of a kind. It is machined out of a billet piece of aluminum on a 5 axis CNC machine. This allows the wheel to support very high boost levels, making huge power while spooling like a much smaller turbo. RWHP rating is 850. Features the anti-surge compressor cover.
SP72GTQ ($1195) A very good turbo, known for its excellent compressor wheel whose excellent design virtually eliminates all possibility of surge on our motors. Features the anti-surge compressor cover. RWHP potential is 870.
SP73HO ($1250) Another new turbo from SP! This turbo features a one of a kind compressor wheel, mated with a turbine wheel from a GT42 turbo. This results in ultra fast spool and RWHP potential of 900+ A recent SP customer strapped this turbo on his car and on his first pass at only 26psi ran a 10.22 and quickly proceeded to be kicked off of the track for lack of safety equipment!! Features the anti surge compressor cover.
SP74GTQ ($1199) One of our most popular turbos, we have recorded 905 RWHP with this turbo without NOS and Matt Miller ran a 9.96 with this turbo making him the first 6 Spd NO NOS Supra in the 9s!!
SP74HO ($1250) The high output version of our 74 features the GT42 turbine wheel. Expect about 50 more RWHP with this turbo without much if any sacrifice in spool!
