EA82Loyale Posted January 24, 2006 Share Posted January 24, 2006 Do the internals of the EA82 NA differ from the internals of the EA82 Turbocharged?? If not i have a whole EA82T engine, but the block is bad/turbo is still good... Can swap and put the parts on my engine?? Thanks, Bill Link to comment Share on other sites More sharing options...
Caboobaroo Posted January 24, 2006 Share Posted January 24, 2006 you just need to swap the heads and depending on what block you have (carbed, SPFI, MPFI) it'll raise the compression ratio which will make the car a bit quicker. Also, swap the intake as well since they differ between the turbo and non turbo MPFI cars. Link to comment Share on other sites More sharing options...

Time to swap then...man i'am having a good day...i got another 4WD Subaru W/ Turbo, i found i can take that turbo and put it on my car that already runs...and i got a date with this girl...like three good things in a day....i'am on a roll guys!!!

ballitch Posted January 25, 2006 Share Posted January 25, 2006 thats a good question, are the EA82T internals forged? or stronger in general vs. non-turbo EA82. the carbed block into a SPFI car lowers compression so if you put a SPFI block under turbo heads you might get a little boost in compression. ~Josh~ Link to comment Share on other sites More sharing options...
Hodaka Rider Posted January 25, 2006 Share Posted January 25, 2006 My EA-82 SPFI is apart right now. Forged rods and crank, cast pistons. I believe the main difference with the turbo is the pistons, but don't think they are forged, just dished for lower compression. Link to comment Share on other sites More sharing options...

As far as blocks go, the only differences between and turbo and a nonturbo block is one or two things depending on what nonturbo block you have. The turbo blocks have a PCV coming from the back of the block right next to the bellhousing sticking straight up into the air and also has a hole for the knock sensor. IIRC, the carbed and SPFI engines have no knock sensor but the threaded bung for them should be there I believe. The nonturbo MPFI block has a knock sensor but no PCV and the turbo has the knock sensor AND PCV. Link to comment Share on other sites More sharing options...
Snowman Posted January 29, 2006 Share Posted January 29, 2006 The other difference that wasn't mentioned (or maybe I just didn't see it) is that apparently the EA82T main bearings are slightly wider for more surface area. However, many people have run N/A blocks with the turbo and no bearing failure, so I don't think it's a problem. So, to recap, aside from: 1. Different pistons 2. PCV port 3. Wider main bearings The EA82 and EA82T are identical from the headgasket surface inward. Link to comment Share on other sites More sharing options...
