We now offer a 6 blade 56mm x 73 x 75mm billet extended tip compressor wheel for the Evo 8 and Evo 9 turbo chargers.  We can match the 56mm compressor wheel with a tdo6sl2R (54mm x 61mm 11 blade) or tdo6h4R (58mm x 67mm 11 blade) turbine. I pair this 56mm billet wheel with the tdo6sl2 for the first dyno testing. Im hoping to see great horsepower results out of it with the tdo6sl2R turbine.

So far we have only got test results for the tdo5hR 20g (cast wheel, unclipped turbine) in and evo 9 turbo. Our results proved 493 awhp and 560 hp to the crank @ 31 psi.  We have not gotten results for the billet wheels yet. These two turbo are leaving for testing tomorrow 6/19/13. Both turbos have tdo6sl2R turbine upgrades and evo 9 10.5 cm^2 turbine housings.

Evo 8 56mm x 73mm x 75mm billet wheel upgrade on the right.

For a reference on what to compare the 56mm turbo to our competitors, the fp Red has a compressor wheel approx (56mm x 75mm) and it uses a 58mm x 67mm turbine tdo6h4R shaft.  We can offer the tdo6h4R turbine, but the evo 9 turbine housing is so large that we were not concerned about picking up additional airflow on the turbine side. We were really impressed with how effective evo 9  turbine housing minimizes back pressure in the turbine housing at higher boost levels and higher rpm.

We also can build these turbo chargers with a billet 25g compressor wheel (60.5 mm x 78mm). We have seen kinugawa use a tdo6sl2R turbine but I strongly recommend the tdo6h4R turbine, because the tdo6sl2R turbine is so small compared the to the size of the 25g.  The tdo6sl2R turbine will never be able to support the flow of the 25g compressor wheel and you would be better off with a tdo6sl2R 20g over the tdo6sl2R 25g.  This is why we recommend using wheels close in flow rates.

You will be happy to know that Turbo Lab takes very good care of its customers when it comes to pricing. Unfortunately we can’t offer brand new evo 8 and evo 9 turbo chargers to build, so we buy used ones to build and stock on our shelf.  If you don’t have a core turbo charger we can just sell you a turbo charger that we have modified for your vehicle. The cast 20g compressor upgrade with rebuild is $400 and with billet wheel $550. The Evo 8 and Evo 9 rebuild and upgrade to the tdo6sl2r/20g billet compressor wheel or tdo6sl2r/56mm billet compressor wheel is 700$ with a core (parts and labor included).  If you want to upgrade to the tdo6h4R turbine, the cost is an additional $100.

If you send an evo 9 turbo in or if you are buying an evo 9 turbo from us and you plan to t0 upgrade to the billet 25g, we have the option of using an anti-surge compressor housing. The anti-surge compressor housings are only avaiable for the evo 9 turbo chargers because of the larger diameter of the bearing housing and compressor housing. The total cost of the build for an evo 9 25g, with tdo6h4R turbine, and anti-surge compressor housing is $800 with a core.

If you don’t have a core, you can purchase one from us.

We hope to hear from you soon.
