Magnum517 Posted September 6, 2014 Share Posted September 6, 2014 Hey all just curious. I read through the mods stickies and know it says this is a bad idea. But I am curious a to whether anyone has put a turbo on their original motor with any success. I know it's an open deck block but so are most of the Honda 4 cyl's that guys are turbo-ing all the time. And I also understand that the 9.5 compression is high BUT there again guys are installing turbos on stock mustangs with same compression and higher. It is more about having the right combo in some cases. Really just looking for anyone w real world experience and how they made out. And please, I don't want to start a huge debate or war over why you can't or can, just looking for those that have tried it ( if any) and what happened. Thanks.

GEE-OTTO Posted September 6, 2014 Share Posted September 6, 2014 Plenty of 2.5RS guys running a EJ25D or 251 installed and are still running AVO's turbo kit they made for that platform problem free. Link to comment Share on other sites More sharing options...
Magnum517 Posted September 6, 2014 Author Share Posted September 6, 2014 So am I correct in my assumption that our motors are pretty much the same as the 2.5RS motor? Because I saw a bunch if those with turbo kits and that's what got my gears turning. Sent from Mos Eisley using Tapatalk Link to comment Share on other sites More sharing options...

TexasLegacy2.5GT Posted September 9, 2014 Share Posted September 9, 2014 Don't do it. for the amount of money that you will spend for 8psi....The Swap solution is so much better. ANYTHING else but a EJ25D..................Anything Link to comment Share on other sites More sharing options...
Magnum517 Posted October 30, 2014 Author Share Posted October 30, 2014 Ok folks doing some homework , and realized that one of the reasons given for not using the EJ25D is kinda false. I was told to not use it because it is an open deck and ha weak internals. Well , almost all subaru motors built since 96 are open deck including the WRX 2.0L and the crank casting is the same as the ones used in the turbo LGT and foresters. Only true difference is the rods and Pistons. So I am thinking of doing a rebuild and just dropping in a decent set of rods an Pistons that are stronger and will drop my CR down to a more boost friendly 8:1. Anyone done this? Thoughts?

Legacy_Guy Posted November 1, 2014 Share Posted November 1, 2014 Swapping the internals in the EJ25D would be your best option if you're looking to boost. If you were to use your stock block, you could probably do it for right around a thousand dollars, your biggest expense would be the cross-member and EM. As other have said, check on rs25.com, that is the go to place for diy turbo setups. I had my '99 boosted for 2 years running 8psi daily, did multiple track days, autocross it regularly and it still has great compression today. I say "had" because I returned it back to stock when I purchased my 07 LGT in July. It was a fun car when boosted, made more power then a 02-03 WRX and surprised quite a few people. http://i717.photobucket.com/albums/ww176/subydude1983/photo_1_zps3aa5e290.jpg http://i717.photobucket.com/albums/ww176/subydude1983/Oct223rdgearvsstock3rdgear_zps0ca1fc95.jpg Link to comment Share on other sites More sharing options...
