I am ready to upgrade my turbo. I have a fully built 13brew with an E6K running 720/1600 injectors. I currently have a TO4S making low to mid 400s at 18-19 psi. The goal is 550-600rwhp.I am considering the following, a gt35/40, T66, GT40. I have yet to see anyone making more than mid 400s with the 35/40, but I would love to see a dyno showing more(as would the owners of these turbos 
) I have all the supporting bits done for this project with the exception that I will need a new manifold to fit the bigger turbo(HKS cast now). Any input is appreciated, Carl

it will be very hard to made that kind of power with pump gas, race gas is a different store, to made 550 rwhp you need more the 720 primary, more like 1600/1600cc. also you need a completed fuel system, fuel pump like the aeromoitve big pump and some after market fuel lines. good luck, keep up post it

Yeah, make sure you have your basics, like bigger injectors, bigger fuel pump, whatever it takes to have enough fuel. And to run the kind of psi to get those numbers you'll need race fuel to keep from blowing motors, but i'm sure you already know. Have you ever thought about doing a partial bridge port or even a full bridge? Is this more of a race car or something that will be driven on the street?

Fuel is a big bosch pump(can't remember which one), supposed to be good for 600hp, -8an from the pump to a SX RRFPR @ 1psi/lb of boost terminating at around 55psi on the gauge. -6an line from thereto 720cc primaries and 1600 secondaries(65% duty cycle @18psi boost). In addition I am going to add an external pump and a surge tank at the same time as the turbo. The existing set up is as follows; 88FC,Kirk 8 point weld in cage,way too many gauges, Avcr,E6K, 13brew(13bt plates) with all oil and water cooling mods, various competition bits inside, Street port, HUGE custom two pass Griffin radiator, custom air seperator tank, HKS fmic, two stock TII oil coolers,10mm race wires, ngk race plugs, custom aluminum catch can/breather,new TII diff, Carbotech panther xp race pads,stainless break lines, Full Ground control coil overs w/camber plates, BIG adjustable sway bars front and rear, TSW Hokenhiem 17x8 rims w/Toyo 235-40-17 RA1s all around(need bigger rears!!!) and so on, and so on...Runs on 100 octane all the time(I have a 55 gallon drum in my garage) Waaay tooo much work for only 430hp... Temps are 190* oil and water after 20 minutes on the track @80* ambient (secret cooling mod) Hope this helps, Carl

Gonna do it on a street port The secret cooling mod goes like this; remove all underhood insulation particularly the rubber at the back of the hood. Remove the rear of two bolts holding the hood to the hinge so that the back of the hood can cantaliever up about 1.5"-2". On the second gen, cut an oval shaped hole in the bumper just like the FEED, and GTC except much larger,roughly 3" high and 24" long. Cutting the bumper support is a bitch :redface: , relocate anything in front of the radiator(except coolers) to the engine compartment. These mods dropped my temps 35* both oil and water. I may have to block off the opening for highway driving as my oil temps are only 150*-160*(water 175). I run 5w30 redline so the low temps may be ok for cruising for the street that's it The hood will lay flat (stock) at rest, and cantilievers up at speed. For the track I use two large rubber bumpers at the rear of the hood. Good luck, Carl
