I run Short header and 2143 pipe with 6.5 v2 venturi. Very linear power band, balanced bottom, mid and top end. Enough power to run slightly over geared with this setup, buggy or truggy.
If on a large/fast track, run it with a 7mm v2 venturi, top end will scream. Expect 8-9 mins runtime average. Excellent mid price engine
