Upgraded turbo outlet for Toyota VVTi 1jz.
The stock cast steel outlet is restrictive and heavy. This piece is mandrel bent 304 stainless, fully tig welded and back purged for long service life. This pipe bolts strait up to factory turbo and O2 sensor, it also has 3inch V band flange and wideband O2 port. It allows smooth exit from turbo and nice merge of divorced wastegate.
Just bolting it on with stock ecu and wastegate, making no other changes, gains were noticed over the entire rpm band with no losses anywhere. It made 250ft/lbs 1000 rpm quicker and gained 22ft lbs of torque and 26hp overall. This was on stock boost, no controller or tuning! It would do even better at higher boost levels thanks to its low back pressure design.
Check out the back to back dyno test, same car, same day, no other changes made
With stock pipe the engine made 273ft lbs and 287hp.
Only changing the outlet made 295ft lbs and 313hp!
Perfect for a swap. Fits s13, s14, cressida, sc300
