Description
WE HAVE THE Garrett WORLD RECORD HP FOR Both Hondata and Motec at 762whp on Hondata and 1000whp on a g35-1050 internal gate turbo and with full 3” exhaust.
Another is highest hp 62mm turbo at 800whp with room to spare in the turbo.
One big advantage to hand porting is the ability to compensate for casting imperfections that a CNC machine can’t tell are there . Having the ability to polish the extremely difficult exhaust port internals on these cylinder heads can only be done by hand.
While yes we did make 550whp on the stock engine in 2021 it took a really high 33.5 psi to make it. It took 6 less psi to make an additional 24whp at 574 with the street ported head. That’s a very large reduction in turbo stress and less work the intercooler has to do to keep up with the heat.
Please keep in mind a ported cylinder head requires significant tuning adjustments to take advantage of the power available. Even stock turbo cars can benefit greatly from a ported cylinder head when it is properly done.
Our unique porting service helps keep low lift airflow and some tumble properties so that you do not lose low end torque. Turbo spool is reduced 500-700rpm and response time was dramatically improved. The exhaust exit radius from the cylinder head is changed to allow better exhaust air transition out of the cylinder head.
Shipping is billed separate and must be paid when the cylinder head is completed.
Prices are based upon a stripped cylinder head. Please Do not send us your cylinder head with camshafts and rockets unless requested full build up.
