Hey guys, haven't been back here for a while....
Just want to ask a Q about the FS-DE (SP20) engine in relation to adding some boost. Now from reading posts on this site and some of the forum members here giving good advice in the past I seem to remember that the weak points in there engines are the rods.
I know one or two of you have done turbo installs yourselves or with overseas kits etc etc... whats the general consensus about boost pressure/power levels before you run into reliability problems on these engines?
And also, the power you can get out of the stock injectors before running over say 90% duty cycle, maybe a malpassi might need to be added in there too to squeeze a bit more out? I think the stock fuel pump should be able to handle a minor increase in power.
We are thinking of running a T28 off a sr20det (not a T25g), or something around the same size (a turbo off an old single turbo 300zx would be nicer).
A 450x300x76mm intercooler is already on order.
A 2.5" exhaust
A microtech running the show (had to be sent back cause the sensors were not compatible with the computer they sent up, since its the first for this engine).
A malpassi IF needed, and fuel pump if needed.
All of this combined should run around 8psi through the normal wastegate actuator, maybe spike to 9psi... is this too much boost or power for these rods (tuned correctly of course, no pinging, running rich), whats your thoughts???? I gather this should net around a 70-80% gain, ie., around 170-180KW at flywheel.
