lilj Posted June 20, 2004 Share Posted June 20, 2004 Ok, my car has two leaky fuel injectors at the moment.. and I want to replace them. However, I've seen the aftermarket fuel rails like the JSK one.. and I HATE the stock one. I will be replacing all of my hosing under the hood with some nice steel braided hose + fittings. I would like to also replace the fuel rail. I read somewhere *i thought* .. that the JSK fuel rail used DSM injectors. So I figured 'cool, now I can just find some dsm injectors that are the same cc as mine, and just pull one set, and then two more and be done.' Well, I looked on ebay, and DSM injectors are 450cc. My problem is obvious, how do I tune down the fuel supply? FPR or what? I want to upgrade the injectors and shit for the future addition of a turbo.. but I honestly don't feel like flooding my engine with fuel. Do you guys think I should go ahead and buy the new fuel rail and injectors? or just buy 2 OE ones? What all would be assosiated *parts wise* with doing the injectors/fuel rail change? All input appretiated. thanks, -jon "well, while im at it.." Quote Link to comment Share on other sites More sharing options...
ToplessZ Posted June 20, 2004 Share Posted June 20, 2004 Alright you have been around long enough to know how to use the search function... but I'll cut you a little slack. Jsk fuel rails are available for stock injectors Im not sure if the new ones he has are compatible with the dsm injectors without modifications. On to your question about swapping the injectors though. I dont believe you can use the dsm injectors with the stock ecu but I may be wrong. You definatly need a totally upgraded fuel system. There is really no need to upgrade your injectors until you want to get past the 250 hp mark. I would just replace the seals on yours which can be done for 12 bucks (ie advanced auto parts), and the connectors which can be had for 15-20. Check for any cracked injector bases. Those can be had cheaply from the jy. Have your injectors cleaned. Or soak them for a day in B-12 before running them and you should be good to go. By the way the JSK stuff is kick A$$ Quote Link to comment Share on other sites More sharing options...
lilj Posted June 20, 2004 Author Share Posted June 20, 2004 Yeah, I used to search function and found the specs on the injectors and what not.. I know his OLD fuel rails were DSM (searched more.) New ones don't seem to be however. That answered my question, the compatibility with stock ecu. I will just go ahead and replace my seals and what not, and just *hope* that fixes it. thanks for the info and what not, i really just wanted a general opinion.. and you hit it right on. appretiate it. -jon Quote Link to comment Share on other sites More sharing options...
ToplessZ Posted June 20, 2004 Share Posted June 20, 2004 No problem. I just got done doing the seals on my injectors and it worked like a charm. Not a hard job either. I would also recommend replacing the hoses that connect the fuel rail and injectors too. Happy Boosting Quote Link to comment Share on other sites More sharing options...
