I've just bought over a jrsc from my friend but it doesn't comes with this fuel enrichment relay.Would it be fine if to fix up the supercharger without this fuel relay?Many thanks.

 

Does it have the boost pressure switch for the manifold? The earlier CRX kits didn't come with the fuel enrichment setup. I ran mine for a year without one and didn't have any problems but I would reccomend using it if your going to run the fmu setup.

 

Thanks for the info.I bought over this jrsc from my friend's ek4 setup.I'm driving an ef8.Did read from the installation manuals that need to put on the relay.But my friend didn't have it...so i'm not too sure whether will there be any effect on the engine if i don't fix up the relay.Anyway..thanks for your info.Cheers!
