What new pistons avail for EA82T ?

i think a few of us are watching this post eagerly.... any head work?

what are the chance of being able to find out all the specs you have got of your motor... what sort of power are you achieving, also are you still running standard injectors?

computer is a microtech LT-8, set up with a reluctor type pickup to use a standard ea82 magnetic pickup disy. i fitted and tuned it myself. the computer has its own loom which you cut to fit and hookup to injectors, water temp sender, disy, module and coil. fairly easy install. heads are standard, gaskets are the cheap acl type. i run a liberty rs water to air intercooler. ive got heaps of photos but dont know how to post em. injectors are standard, and are touching 100 percent duty at 6500rpm at 15psi with a rising rate fuel pressure reg at 70psi. ive got some vl turbo injectors that ive got to put in the ultrasonic bath and then fit and tune again to suit, hopefully this time at more sane fuel pressures. i dont know how much power it makes, its never seen a dyno, i didnt see the point.

do you know the flowrates of the standard injectors? The VLt injectors aren't very big, actually the same as an ET pulsar. 48hp each or 250cc/min.

from what i have heard u want yellow top injectors off a magna... they are not much bigger though... next bet was off an early 200 and or just get our injectors flowed

mine are hitting 100% at 5000rpm

point there is a thread a while ago about injectors for the ea82t and there was some good infomation there to be had

the injectors ive got were pulled from a vl turbo but they are 320cc (flowed them myself). they are hose tail style. maybe this car had had an upgrade previously, but i never checked the bosch numbers.

Just in case you never see them EA81 pistons appear to be flat top and no valve reliefs . I think I'll stick to the NA EA82 piston idea , intercool and stay with 98 oct PULP .

mine are flat top in my EA81 , but did you compare gudgeon pin to top as being the same on the 82 ? I have not, so don't know, but it is a consideration

No actually , its lying in the padoick at a wreaker and I just pulled off one of the heads to have a look . Will be back eventually so if someone can tell me if there is a special tool to remove the hex head plugs and gudgeon pins I'll pull one out and another from an NA EA82 that already has one head off .

The thing I don't know is the valve angle differences and piston to valve clearances between EA81/82 .

Cheers A .

to get the plugs out you will need a 14mm allen key, thay can be real tight. but i dont like your chances of getting the piston pin out with the motor in the car, they are always stuck real good, can be a struggle sometimes even on the bench with a slide hammer. although, every once in a while they just about fall out easy as with a pair of pliers.

I'm running flat top pistons in my EA82 MPFI, on the side of the box it said EA71 from memory, i'll check it up tomorrow. The pistons looked the same as eachother except the new ones were flat top... Maybe i'm setting myself up for some bent valves if a cam-belt goes?

And the pistons were from ACL (i'll double check that too).

The engine goes so much better than the last one in up-hill pull, fuel economy and acceleration (got a surging problem though

)

Hope this is of some value (i could go speak to the guy i bought the piston heads and rings from - he did my re-bore and measuring for new bearings etc - ask him what he thinks in a turbo application and if he has a part number).

Also, what's the difference in the turbo con rod and NA con rod?

Cheers

as well as the 14mm hex socket, about $20, a 600mm breaker bar is good. so too is some heat applied around the plugs to expand the alloy a poofteenth and melt any glue. I used one of those $20 butane torches.

Righto , will go buy a 14mm half inch drive hex tool . Breaker bar I already have , needed that for the hub nuts .

Thanks Adrian .
