ttodhunter Posted June 30, 2014 Share Posted June 30, 2014 Hey all, I'm in the process of putting my built N/A motor back in my 76. I figured with the expected power increase, I would put in the turbo 265cc injectors (running SDS efi). I bought a set from Autozone, and noticed that they didn't come with the pintle caps. Oddly, there doesn't seem to be a thread regarding upgrading from L28e to L28ET injectors, or what steps would need to be taken. There are a couple of threads relating to running with or without pintle caps, but with differing opinions. Here's a picture of the old vs. new: The injectors fit in the manifold fine, but I'm concerned about the purpose of the pintle cap and me not having them. Can anyone shed some light on what is needed to do this correctly? Thanks! Quote Link to comment Share on other sites More sharing options...
NewZed Posted June 30, 2014 Share Posted June 30, 2014 Your new injectors have a different, newer style of nozzle. I've seen it on a few other brands, like BWD and Standard (yours are probably one of those brands). Your new injectors aren't designed to use a pintle cap. The tender pieces are recessed inside the injector tip, protected. As far as directions on what to do when increasing injector flow, those would be in your SDS instructions. Lower injector open times would be the main change. Quote Link to comment Share on other sites More sharing options...
ttodhunter Posted June 30, 2014 Author Share Posted June 30, 2014 Thanks for the reply. Tuning and break in is my next can of worms- but the injectors should be ok- whew. Quote Link to comment Share on other sites More sharing options...
