Compiling list for Turbo
Well ive decided to scrap the NA power route and head for the turbo route.
Now, as im frequently broke ive decided the best way to go about it is to list everything i need to install a turbo system, down to oil lines and heat wrap. So far ive decided on the following.
EF/L Crank + Rods (mabey shotpeened)
EA Pistons, ACL Race 20thou over
Stock EF head (mabey EA head with swirl chamber machined out)
EF/L inlet manafold
The engine will be rebuilt using all new bearings etc and fully balanced
As for the turbo setup ive been thinking of the following
2 x VG30/T04e hybrids.
a single turbo of this description has been used by a friend to make 250rwkw @ 13psi on a RB25DET. With no machining on the turbine snout it make 15psi @ 2500rpm on a 2.5L engine, however this was to much flow for the engine and the turbine snout was machined out to slow down the flow rate and turbine RPM, eventualy 15psi was obtained by 3800rpm.
Now with a 4L motor 2 of these (unmodified snouts) should be making 9psi by arround 2500rpm, yet still be able to easly push 15-17psi if nead be.
I have not thaught about piping, exhaust manafold or intercooler aspects of the setup.
Im wondering what people this of this setup, and any ideas and comments regarding this setup. My first concern would be regarding the fact that 2 VG30/T04e turbos could be to large for an auto street car.
Btw, the fueling system will be by means of a GRA straight gas setup so no work with the ECU/fuel system need be worried about.
Ive been described as a vault of usless random knowledge.
Ill take it as a complement i think.............
