Hello everybody, I have recently purchased a m40b18 motor with a turbo attached with a few goodies, I will be updating this post frequently. This is the list so far ( Made 300HP on 20PSI )

XR6 Turbo injectors, T28 Turbo and housing, modified manifold, intercooler and piping, 10/20psi boost solenoid, thicker head gasket, ARP head studs, 3inch dump pipe. Adjustable coilpacks

I am needing a ECU for a cheap price it may be stingy but I've seen emulators such as 'ostrich 2.0'
' for a fairly cheap price where I can adjust timing and fuel ratios ect. Any recommendations would be great as I'm planning to slam this in asap! yes I know 6 cyl would be the way to go but someone didn't need this and sold it on cheap to me. Previous owner ran it at 20 psi surprised it didn't explode but ill be looking for 10-13 psi at 230hp ish.. I know people say these engines are terrible for boost ect and will blow but I know people who have done this before and been good! hopefully it rips!



More updates and photos coming tomorrow!Image
