Hello all,
I am in the process of rebuilding an old school FP 20g(52.6X68 compressor wheel) with a TD06H turbine in a machined 14b turbine housing. Does anyone have a clue on what flow rates would be seen? And has anyone dyno'd a similar setup? Why would I run the 14b housing? Because it's a direct bolt-on housing that has enough material to machine off for the TD06h turbine. OR, has anyone dyno'd an older FP 20g?
How big of a difference is it to run a less flowing turbine housing when using the TD06H turbine?
Original FP 20g:
52.6 X 68 compressor
58.8 X 67.2 turbine
8CM^2 turbine housing
- Not sure what the turbine A/R is
My new setup:
52.6 X 68 compressor
58.8 X 67.2 turbine
6cm^2 turbine housing
- Un-ported turbine inlet(2") with machined turbine outlet(68mm or 2.67") yields an A/R of roughly .75(typically faster spool up, more low end torque)
- Ported turbine inlet(2.5") with machined outlet(68mm or 2.67") yields an A/R of roughly .94(typically slower spool up, but more flow to maximize turbine output, more high end power)
If it matters,
Engine mods:
6 bolt
6 bolt rods, 2g pistons
built head
DKS 272 cams
Stock intake and ported turbo manifold
Every single hot part is port matched
2.5" intercooler and intake piping
