Hi all

 

I'm starting to think about my next round of upgrades/restoration parts

 

I'm sure several of my injectors are blocked/stuck open which I'm quite sure is my own stupid fault for not cleaning out the fuel line before connecting it all up. I already replaced one as I has a misfire.

 

Replacing them is no big deal but I'm wondering what to replace them with.

 

Stock would be the most simple/ cheap as they will drop in and require no chip etc but will not give me any future proofing

 

550 nismos would be great as they drop in but require an obvious remap- they would have enough capacity for me I think but are real expensive

 

750 nismo/ jecs etc would be cheaper to buy but need adaptors etc and a remap

 

I know there are hit and miss reviews on a lot of the jecs / reflowed injectors but I think most of this is hearsay

 

Anyone know of some nismos for sale?

Deutsche Werks 555 are top quality and depending on what fuel rail you have the fitting kit is first class, and should not break the bank either.

for early cars i take you will need extra bit to fit them,

Thanks for the feedback Jeff. That is one of the options I was considering. It's hard to find first hand experience on anything other than the nismo's

 

As a very low cost solution there is also these

At £230 they seem very good value, I guess they are the same reworked jecs as sold by concept z. A bit of a gamble I guess

Dan, yes any pre 94/95 car will need them as the fuel rails are different.

 

I'd be a little concerned about the spray pattern on the later style injectors as Nissan revised the lower manifold and heads to accommodate their wider spray pattern. Maybe nothing to worry about though.

Check this before you take my word for it. I believe jecs=nismo. By far the cheapest way to bigger injectors is to buy them off something else, some scoobies have 500cc jecs injectors that fit in the late spec rails. Obviously bear in mind you must match the injector connector with what ever injector to fit. Equally as you know you will need a chip or map to suit the injectors which is where using tried and tested ones come in... How big an injector do you need? Do you even need new ones? Or would having the stock ones cleaned and tested do the job?
