Nope,all internal parts are the same except the pistons.

All the same - I have a turbo crank in the engine I'm building right now. Side-by-side comparison they are identical. I just happened to have the turbo crank already turned, and an oversized bearing set for it so I used it instead. Got it from a board member who's project engine got caught in a garage fire - crank and new bearings were in his rig cause he had just picked them up from the machine shop :eek:

gd,

 

so the cam is the same too

 

Cam is not the same.

 

Solid lifter, hydro lifter, and turbo (also hydro, but different compression) all had different cams. That is they have a different lift and duration. It will physically fit, but it won't be the right grind.

gd,

can ya put solid lifter and matching cam in a hydro block???

Why would you want to do that? Yes, you could, but you need the push rods, and rocker assembly as well. The hydro's are better all around as they don't need adjustment. And the EA81 hydro lifters rarely tick like the EA82's. Plus the hydro rods are steel and the solid are aluminium.

You would want to do that because of the excessive price that subaru charges for new lifters - it was gonna be about NZ$500 for a set of hydro lifters for my ea81.

 

Interestingly enough, im using hyro push rods and rockers.....

 

The push rods differ in length slightly, but seem the same otherwise...

 

as for the rocker arms, i still cant work out what the difference is.... maybe the only difference is the part number...!

 

This set up seems to work fine.....

Well - there's Delta cam in Tacoma that sells new lifters for $7 each, and then there's also these guys that will rebuild your cores for less than $5 each:

What, ea81 hydro ones?

 

Still, that would end up being fairly expensive with shipping to NZ, not to mention having to wait around 3 months for them to turn up!

 

If mine had hydros in it when i pulled it apart i'd probably have stuck with them, but someone had already converted it, so i'd have had to get a new cam too.....

Yep - that's what they quoted me when I called. And even if that wasn't the case, the other link I gave will rebuild any lifter for like $5 each.

There very pricey in Aus too, thats if you can find a set, we would normally have to get these types of spares flown in from Japan and that also adds to the cost. The prices you have quoted would make it far easier and cheaper to order from the States, s**t, you would even save enough this way to have them air freighted in 7 days, very handy info, thanks.
