Warped Injector Housings - ZR-1 Net Registry Forums

LGAFF · 05-05-2014

A few years ago I took some prototype injector housings and siamesed the runner. The walls were much thinner than stock and I Epoxied them were it was thin. In Prep for my new powdercoat I had them sandblasted and they turned into swiss cheese. I was just going to go back with Epoxy, but the PC guy talked me into "doing it right"....by TIG welding

Alittle welding and now they are warped pretty bad, the gasket seems to make up for it and they seem to straighten when they are bolted down. However, not sure I would trust that the gasket is compressing and how they might react to heating and cooling cycle. Biggest fear is coolant getting in the intake....

guess its time to get a set of injector housings from the basement and start porting
