is it possible to turbo the 02 se-r motor?
is it possible to turbo the 02 se-r motor?
yea my buddy had a turbo on his only runnin like 6.5 psi thoughOriginally Posted by auxiliary
turbo was to small though started losing power at about 5 grand
Do you know why this is?
Perpare to get schooled.
The qr25 motor is a very oversquare motor. Meaning it has long stroke and short rods. The piston speeds get insanely high at around 6500rpm on the stock rod length. This means volumetric efficiency falls way off, and the piston can't effectively draw enough air and fuel into the cylinder on the intake stroke. That is why the power drops off. Why waste your time turboing a 4 cyl if you can't rev it past 6500? You won't make any power.
Now if you could shorten the stroke of the motor and put in longer rods you could have yourself a decent motor. This has been attempted by putting an sr20de crank into the motor. It lowers the displacement however but it does allow it to rev higher and smoother. Making it a better overall motor.
well ok then
I'm gonna guess you have no idea what any of that means.
So lemme make this simpler.
qr25de = bad motor to turbo
sr20de = good motor to turbo
b13/b14/b15 2.0 sentra > se-r spec v.
sr20 crank fit in one, just straight out or gotta be adapted to fit?
goddamn your a dickhead
well anyways i gotta get back to work lunch break over, i enjoyed arguing with u guys u dont find too many real grade a assholes, i like that its the type of people i usually hang out with i enjoyed it fellas, maybe we can do it again
The motor had to be machined the fuck out of it.
I'm not sure if it was ever even finished.
