- Nytro turbo
Hello, i have nytro that has turbo and about 6 psi pressure now, fuel control by PC V. So im planning to add meth injection, bigger fuel injectors and fuelpump/regulator upgrade and intercooler etc. and keep original compression and stock internals in motor.
One thing that has been in my mind is that is there Mcexpress turbokits that has 270hp somekind of ignition control or is it still running and working with naturally aspirated motor ignition timing advance?
Its hard to find ignition boxes for nytro or do i need one if i use about 15- 16 psi?
Hope you undestand sorry bad english

MCXpress kits use stock ignition timing still.

All depends on your compression ratio & fuel octane you are willing or can use.
