N/a injectors

Sonyps307 · 01-31-2012, 03:27 AM

Ok so I burnt a exhaust valve in cylinder 6. So to start with my mods the motor has been rebuilt .040 over, k&n filter, obx header, and full 2.5 catless exhaust. So I'm wondering if I'm maybe I'm running lean but the valves we're not replaced they have about 230,000 miles on them. Also maybe the injectors r dirty.

So send them in for professional servicing. I recommend getting and sending in 2 or 3 extra injectors so you can put together a matched set when you get them back. Toyota's specs allow for a significant disparity in flow rates from one to the next... IMO it should be less than a couple percent. RC Engineering (www.rceng.com) and Cruizin Performance (www.cruzinperformance.com) are two which I have had good experiences with; during racing season RC tends to have a longer turnaround time.
