TheSubaruJunkie Posted September 12, 2006 Share Posted September 12, 2006 The latest EJ25 turbo. In stock form puts out 300hp. -Brian Quote Link to comment Share on other sites More sharing options...
calebz Posted September 12, 2006 Share Posted September 12, 2006 true, the USDM STi puts out a stock 300/300 The newer (V6 and up ) EJ207 comes near that right out of the box, but with forged internals and supposedly, a better fuel system.

calebz Posted September 12, 2006 Share Posted September 12, 2006 so would any of the old transmissions be able to hold up the the new ej25 turbo? Sure For at least 15 seconds. Quote Link to comment Share on other sites More sharing options...
86ruguy Posted September 12, 2006 Share Posted September 12, 2006 they'd hold up that long? Quote Link to comment Share on other sites More sharing options...
TheSubaruJunkie Posted September 12, 2006 Share Posted September 12, 2006 I wouldnt even give them 15 seconds. You'd already be doing 100+ by then, i give it until 40mph which would be about 6 seconds. If you want the most potential power, maybe the 3.3 liter H6 (EG33) would be a better platform. Supercharge that sucker and get ready for some real power! -Brian Quote Link to comment Share on other sites More sharing options...
7point62fmj Posted September 12, 2006 Share Posted September 12, 2006 Jeff Perrin has a H6 STI. The video is floating around on the web. he is dong some thing like 450ish tq... I think. Quote Link to comment Share on other sites More sharing options...

Dr. RX Posted September 13, 2006 Share Posted September 13, 2006 Here's the problem, most Japanese horsepower figure are not the actual horsepower output, they are ratings giving for insurance and an agreement between Japanese automakers that no car would produce more the 280 hp. Don't you think it a little strange that the hp in the newer WRX's never got over 280hp, dispite years of development. Heck, even the Type R's and RA's were rated at 280hp, the they are basically street got race cars with lots of internal STi goodies in the engines, to think that they had the same hp as the common street version WRX is crazy. But I think the overall most powerful Subaru engine was the flat 12 developed for Formula 1 racing. Quote Link to comment Share on other sites More sharing options...
beataru Posted September 19, 2006 Share Posted September 19, 2006 Yeah the flat 12 was one sweet cookie but thats oldskool and i wouldnt mind getting one of those but.... If i had billions of dollars i would build 2 H-6 engines one for N/A Power with rods like titanium and such internals and with like 15-1 Compression Ratio a and one turbocharged with a GYNORMAS front mount intercooler and like a GT50R or equal turbo and have that thing forged and boosted up to the moon!!! along with an extreemly high redline for both id say 8500 minimum... ahhh if all subie lovers had lotsa money... we would concor the world of autos! :slobber: Quote Link to comment Share on other sites More sharing options...
