WJM Posted October 16, 2004 Share Posted October 16, 2004 On the right, a STOCK EA82T injector...on the left...same item, but with the ugly yellow/orange plastic 'accidentally' broken off of it completely.... I wonder what kind of difference this makes towards flow or spray pattern or what not.... Quote Link to comment Share on other sites More sharing options...
baccaruda Posted October 16, 2004 Share Posted October 16, 2004 probably a big difference.. but not necessarily a good one good luck though Quote Link to comment Share on other sites More sharing options...

Myxalplyx Posted October 16, 2004 Share Posted October 16, 2004 what would not be good about it....? Ive not got a clue really.Why don't you send it to me with $25.00? I'll put up the other $25.00 and immediately send it off to RC Engineering. Upon return of the injectors, I'll scan the result and send them both back to you so shipping will be evened out. What do you say? We can keep the results to ourselves and charge everyone on the board mucho bucks for an injector upgrade and live happily ever after.

calebz Posted October 17, 2004 Share Posted October 17, 2004 Thats an intersting idea.. Funny thing is, I already have a set of those in the garage cut just like that.. The WRX guys do it with their stock injectors.. brings the flow from stock (440cc I believe) to ~720. I know one guy locally that is using them in an 02 WRX wagon putting down ~285 at the wheels.

nomica Posted October 17, 2004 Share Posted October 17, 2004 Hey, this is Tex on my GF's machine. Our injectors are a needle valve type. Modern WRX injectors are a disc style. Our cover helps shape the spray pattern. By cutting it off, we could lose atomization of the fuel and thus not be as effecient. The screen on the wrx injector (from all that i've read/heard) is actually what fuji uses to set the flow rate of the injector. Example: STi injectors are the same... but with a different screen on them. I think for our injectors to flow more we would have to increase the size of the bore and the size of the needle that fills it. Quote Link to comment Share on other sites More sharing options...
archemitis Posted October 17, 2004 Share Posted October 17, 2004 i have 4 that have the plastic/stock cap thingy, and 2 that i broke, and left off... this is on my toyotav6, and i have ran it that way for years. couldnt ever tell the difference.

WJM Posted October 17, 2004 Author Share Posted October 17, 2004 with the new fuel system I am going to have on my spyder intake...it will make changing injectors a 5 mins job...so I am going to try both sets of injectors and see whats going to happen. I did look at the plastic on the end before i posted...and I did figure by the shape of the exit at the needle...it did have something to do with the spray.

oddcomp Posted October 17, 2004 Share Posted October 17, 2004 well if someone has a couple of dead injectors i could cut them in half with my metal bandsaw maybe one or 2 dead sti injectors might be interesting to compare them thatway..

electryc_monk Posted October 17, 2004 Share Posted October 17, 2004 injector flow rates... that being said where/who has the sheet to show flow rates for EA82 and the ER27 injectors for comparison AND for comparison from the cleaning that you guys are thinking of doing.,.... inquireing minds and all that Quote Link to comment Share on other sites More sharing options...

NorthWet Posted October 17, 2004 Share Posted October 17, 2004 My 2 cents is that it is primarily for spray pattern. Mess with it and atomization will be affected. A couple of secondary possible purposes would be: 1)for tuning of spray pattern (i.e. - change angle of divergence and/or depth of passage), or 2)ease of machining... pintle and seat machining separate from orifice/atomizer, or 3)some protection for projecting pintle.
