 2GRFE Intake Manifold Testing
Sept 2026

20250507_222325.jpg

My Personal 2GR Swap

This is the modifications list for all dyno pulls on this page unless otherwise stated. All Dyno pulls were done on the same chassis dyno with same fuel (E75).  On all runs the Engine was brought up to 180F water temperature and 170F oil temperature. I made every effort to make all runs as consistent as possible. My car is very stable from pull and pull and repeats within 1-2hp.  I made several runs for each test to verify results. I am only posting 1 of those runs for clarity and simplicity. Message me if you need to see proof of other runs.  I was very fortunate to have numerous people send me intake manifolds for testing.
