WJM Posted February 22, 2005 Share Posted February 22, 2005 both have 92MM bore. anyone want to grab some WRX pistons/pins/rods and see about them fitting in the EA82 and get some measurements comparing pistons? All my EJ205 sources are gone. Link to comment Share on other sites More sharing options...
subyrally Posted February 22, 2005 Share Posted February 22, 2005 keep me informed if you come across anything, i need to find out for my build. thanks will. Link to comment Share on other sites More sharing options...
4WDFrenzy Posted February 22, 2005 Share Posted February 22, 2005 Well, I would but the wife would probably get super PO'ed if I took the WRX apart. Link to comment Share on other sites More sharing options...
subyrally Posted February 22, 2005 Share Posted February 22, 2005 i think the pin size could be overcome, somehow.probably just need custom rods. what about the hight from thetop of the piston to the center of the pin? is that the same between the two?

WJM Posted February 22, 2005 Author Share Posted February 22, 2005 what about using the EJ20 rod? its got a longer stroke...but....hmmmm? Link to comment Share on other sites More sharing options...
subyrally Posted February 22, 2005 Share Posted February 22, 2005 what about using the EJ20 rod? its got a longer stroke...but....hmmmm? i think the wrx rod would put the piston through the head, doesnt it already come flush to the deck at tdc? for that, i could see having to get a custom crank shaft made to accomodate the extra length.

MorganM Posted February 22, 2005 Share Posted February 22, 2005 what about using the EJ20 rod? its got a longer stroke...but....hmmmm? You'd prolly redefine the description of "interfearance engine" However maybe not? Whats the stroke of the EJ20 vs. stroke of EA82? Now is there room in the cylinder to compensate for the extra stroke? :-\ Link to comment Share on other sites More sharing options...
torxxx Posted February 22, 2005 Share Posted February 22, 2005 yeah with a longer stroke, you are going to have pistons slappin the hell out of the top of the head. maybe, if you changed the crank to one with lowered stops where the rods connect, it might work, but otherwise, its just pipedreams Link to comment Share on other sites More sharing options...
Porter Posted February 22, 2005 Share Posted February 22, 2005 EJ18 crank with EJ20 pistons? Link to comment Share on other sites More sharing options...
Dr. RX Posted February 22, 2005 Share Posted February 22, 2005 EJ18 crank with EJ20 pistons?Don't think that will work in an EA81 or EA82 engine. The EA81T pistons will give you slightly higher compression then the EA82T pistons, and I know they work, I have them in the 85 SW. Link to comment Share on other sites More sharing options...
subyrally Posted February 23, 2005 Share Posted February 23, 2005 with my engine, im not going for different compression or cheap parts, i am trying to build an engine that will be bullet proof.i want an ea82t that will withstand high boost and possibly high rpm. this is, of course, a long term project for me, i dont expect to be finished till at least fall if not winter.

ShawnW Posted February 23, 2005 Share Posted February 23, 2005 The EJ rods are all longer than EA rods are. Further, the EA pistons have longer skirts typically, and don't tend to have the piston slap issues that EJ series engines are famous for....some being better than others obviously. The Compression of the pistons in the ea series is pretty diverse already as well so mixing or matching within the ea or ej engines should be sufficient for most builds. Otherwise like Shadow indicated you could get special pistons like any other import engine. Link to comment Share on other sites More sharing options...
