ea82 copper head gaskets
Posted 21 January 2004 - 10:54 PM
I bought a manual boost controller, intercooler, boost air fuel and a bunch of other gauges. I want to go throughthe EA82t and also I got a set of genIII heads to put on the 9.5 comp. ea82 engine.
I want to turn up the boost so I want copper gaskets because I have heard this is the weak link.
I want to make one bad little sub.

Anyway, higher compression and higher boost.. you may have more problems to worry about than your head gaskets.. be careful

Tdangelo- be wary that there are some very specific things you need to do to make Cu h/g's seal correctly.
Personally, I like a well-engineered weak link. I would rather smoke a head gasket than have piston residue clog my exhaust. Helpful to have a known weak link while setting it up, before you are comfortable with it, to save your engine if the fecal matter hits the ventilator.

Better to blow a gasket than those genIII heads.
You will also need to upgrade the fuel pump and fuel lines.

If any of you have any ideas on what type of injectors these are high or low impedance hit me back.Does anyone make larger injectors that will work. Does anyone have specs on all the different cams that have came in the Ea82 carb spfi mpfi turbo etc.
As for the heads I won on ebay. I got lucky. I found them not long before the auction ended so yay I bid at the end. You said for yourself that you would of bid higher. I bid once and that is all. If you bid the price that you want to spend in the first place I would not have won. But anyway I will take good care of them.

Up until now, I had not been needing the high end of my engine...now that I have a super ultra sticky grippy suspension setup on my wagon, and a more proper intake and exhaust (exhaust for now, still needs work) I am using that high end. Past 4500 on pupm gas, 93 even, if you have the timing to where you have power down low, you wont have it up high, detonation city. Sounds kinda like and anti lag system if you set it too low so it wont detonate. Now, with race fuel, competition 100 ($4 a gal!!!) you can set the timing quite well, and it pull like a mofo down low, then it will drop off a little, but pull all the way to 6500 pretty strong.
Myos. and Miles Fox has taken one of those carbed blocks and turned it into about 8.5:1 or so compression, with pulls way better and you can still use pump gas on it.
About those copper HGs...http://www.headgasket.com/
You cannot get their sealer as of a few months ago due to some EPA guideline(s)...but that was then, maybe something has changed. I had sealing problems...but i think the main causes were 1: not enough TQ on the head bolts, and 2: slighty warped heads that warped even more dueing and overheat when the sealant crapped out due to not enough TQ.
Make sure you get your heads trued/machined up. absolutely no wareped heads. Thats how my 9.5:1 engine has lasted this long, it has a fresh head machine job. These are Gen2 heads. I have a set of Gen2's if you are interested. But you will have to get them machined.
There are supposed to be Nissan injectors that will work that are larger...ive tried them, and the ECU doesnt like thse injectors.
Cams...there is a huge difference between non turob and turbo...well, the turbo ones are more suited to the turob car and it will make more power with the turbo cams. The 87+ cams are supposed to be the best stock cams to use, so you've already got those.
15psi is about you max on the stock turbo, IC or no IC.
Now i had a semi built EA82T...Delta cams, freshly selaed up, extreamly high flow intake and exhaust...all on a stock turbo shortblock. the thing pulles to no end from 3k to whenever i decided to shift or let off. Pegging the speedo was no problem, and it didnt take all day to get there either. I would STRONGLY recommend sticking with the stock EA82T shortblock, just go with OEM SUBARU turbo headgaskets, machine the heads, get a pair of Delta cams made (677-260 is the part number I think, http://www.deltacam.com/index.htm), and go from there.
