Thinking of putting this turbo on a 250ci 109.
What should I ask 4 as far as heads and flow #s
What size down pipe would I need.
TIA
Where's John Wilde when you need him??

With the right converter and motor combo, this turbo works excellent. A stroker 109 is just begging for this turbo. Cal Hartline did alot of testing with this turbo a few years ago with excellent results. It is available with 4 different turbine housings and with larger CI of a stroker motor, you can use the 1.28 A/R housing. The 1.44 A/R housing would be for 278+ CI motors. This would be for dual bb versions of this turbo only as the journal bearing version would be very laggy with any housing over the 1.01.
Here is the link to the base model used to make a GT4276R.

The comp map is not correct for the GT4276R, as PTE adds the 76mm compressor wheel to the GT4202R turbo to make it a GT4276R.
Hope this helps a little.
