Safe EA81T Mods?
Posted 31 July 2003 - 07:52 AM
I'm probably going to install it in a somewhat stock form and add mods from there. I'll be using an EA82 Turbo, and I'd like to intercool it. I'll also be using CIS fuel injection.
Is it safe to increase the boost?? If so, how much?? What mods can be done to improve cooling??
What about internal mods?? Would a carb cam be an upgrade?? I've heard that turbo cars often have really bad stock cams so that they can meet emissions.
I'm just in the dreaming phase right now, so all ideas are welcome.

There's a place around here (Albany) that'll do it for $45, but then you need to find some place to heat treat it.
hmmm.... but that's pretty good right?
and what do you mean by a little fragile? I thought the EA81 was a 'work horse'? or is there something different about the heads for an EA81T that make it easier to break down?

Good radiator, intercooler, make sure its been converted to the water cooled turbo which the ea82 one would get you, and go from there. Im sure some of the fun things Skip has done to his ea82 turbowagon would apply fairly easily.

With your CIS, get a <strong>good</strong> means to monitor AFR, if you lean it out on boost, your asking for trouble.. I would suggest a more precise meter system with a wideband O2 sensor instead of your normal narrow band you find on most cars, they aren't cheap thou.

I'm putting this into my '80 Hatchback, so I think I can legally get rid of the cat in the downpipe (The sticker under my hood says "non-catalyst"). I had a feeling that larger exhaust would be a pretty good idea.
I don't want to cut holes in my hood either, so I'll watch ebay for an a/w intercooler. I wonder if you could make one by enclosing an a/a intercooler? hmmm.
I don't think I'll actually be messing with cams anytime soon. I was just curious if the turbo cams were too wimpy.
I'm definitely going to be watching my a/f ratio. I'm in the process of building a meter right now. It's going to use 20 LED lights instead of the normal 10 so that it'll be twice as precise. I knew that I'd need boost enrichment. Many european turbo cars from the '80s came with CIS, so there are certainly ways of dealing with this. I'm using CIS because it worked well on my Wagon, and I don't have all the EFI parts needed to use the factory injection system.
Thanks for all the replies. I'm sure I'll have more questions when I actually get the engine installed.
