btlegacy Posted August 14, 2012 Author Share Posted August 14, 2012 If you can upload the pic or shoot me an email with a few I would be forever grateful. The SHO ideas is awesome and I have been tempted to find a use for a SHO motor as there are 4 of them in the local Pull a Part junkyard 2005 Legacy GT 5MT Buy my stuff Here So I can build my 6.0L V8 Legacy GT Here Link to comment Share on other sites More sharing options...
BAC5.2 Posted August 14, 2012 Share Posted August 14, 2012 The SHO V8 is only 7" longer than an EJ25 to the front of the pulley. And it's so narrow, you can keep the turbos low, and piping compact. Drop the CR to ~9:1, and you are all set. Plus, the soundtrack is totally unique and really rev happy. Just make an adapter plate to bolt up a Subaru 6-speed, move the condenser to the front of the vertical core support, and run push fans on an aluminum radiator. It wouldn't be hard to build a somewhat reliable 500hp street car out of that.

btlegacy Posted August 15, 2012 Author Share Posted August 15, 2012 I can see where you are going with that and you can definitely fit it in there with only 7in of difference. It would be a fun car and most unique with that exhaust sound 2005 Legacy GT 5MT Buy my stuff Here So I can build my 6.0L V8 Legacy GT Here Link to comment Share on other sites More sharing options...
BAC5.2 Posted August 15, 2012 Share Posted August 15, 2012 I like the LS idea, and it is definitely a more realistic swap. The SHO V8 swap would be a massive custom effort, not really suited to a project you actually want to finish in any reasonable time frame. It'd likely take 3x as long, and cost 3x as much. What are you doing for EM? I think the GM ECU has all of the provisions to handle the Subaru gauges. The ABS computer is a stand-alone module in the Subaru, and I'm fairly sure that module is what drives the speedo (though it might do so indirectly, routing speedo signal first to the ECU... which could easily be bypassed). The GM ECU should output a 4-cylinder friendly tach signal, which should directly handle the Subaru tach needle. Also, check your PM's.

btlegacy Posted August 15, 2012 Author Share Posted August 15, 2012 I am going to use a GM ECU and Harness. The speedo is still up in the air but we can use a Dakota Digital box if necessary. The tach should be easy and we can throw a resistor on if needed. 2005 Legacy GT 5MT Buy my stuff Here So I can build my 6.0L V8 Legacy GT Here Link to comment Share on other sites More sharing options...
BAC5.2 Posted August 15, 2012 Share Posted August 15, 2012 The tach should be able to be driven from the GM ECU without an issue, and the speedo can probably be driven straight from the ABS computer. Check the FSM for the wiring path for the speedo signal.

btlegacy Posted August 15, 2012 Author Share Posted August 15, 2012 The iron block 6.0 is basically going to be free to me compared to $2k or so for an aluminum 6.0 and the weight difference is really not that big of a deal to me Why not an Aluminum block?

BAC5.2 Posted August 15, 2012 Share Posted August 15, 2012 Plus you can always hunt out an Al block later, too.

btlegacy Posted August 15, 2012 Author Share Posted August 15, 2012 Yepp that is true. Once it it setup once I can swap out to any LSX block easily 2005 Legacy GT 5MT Buy my stuff Here So I can build my 6.0L V8 Legacy GT Here Link to comment Share on other sites More sharing options...

That Guy 2-1 Posted August 15, 2012 Share Posted August 15, 2012 What year LS1 harness? '99 and up went serial comm. for the gauges (except for tach, i think) while '98 has analog gauges; which you could theoretically convert to work with tour stock cluster. Only issue is that '98 pcm isn't boost friendly since you can't use custom tables with a 2bar MAP sensor; but they may have got a solution for that now (it's been a while since I played with them), and you're not planning forced induction ... yet!

btlegacy Posted August 15, 2012 Author Share Posted August 15, 2012 The harness is 03 and so is the ECU. We have used that combo successfully on other cars and are able to get signal from it, I just have to see how to input it to the Legacy cluster 2005 Legacy GT 5MT Buy my stuff Here So I can build my 6.0L V8 Legacy GT Here Link to comment Share on other sites More sharing options...

mustangendsley Posted August 15, 2012 Share Posted August 15, 2012 To me the V8 miata would be much better and funner to drive that a V8 subaru. I have been in a LS3 miata and let me tell you what.
