I will be doing the EG33 flat 6 upgrade to 1 of my 914's,..are there any engine mods that can be done with those engine's,... or are they pretty much 230-240 HP,..I would like alittle more torque from it if possible,..of course I have never driven one with power,..maybe I should leave well enough alone,..which is plan B,........Thanks Frank

Yes...here's a good place to start:
subaru-svx mods page 914SVX power is definitely adequate in stock form if you're used to a standard 4 cylinder 914 but you could do the stage 2 ECUTune with larger 375cc injectors and Nissan MAF and add 50-75 hp pretty easily. We were just chatting about this in 914forme's thread. |

That's about how much power I have. I wouldn't worry about more right now, get the rest of it done and THEN think about more power. You can go back for more later, but it's not a heavy car and i suspect that you'll be pleasantly surprised at how much fun you'll have with that 240hp.

(IMG:style_emoticons/default/agree.gif) Good advice. The power difference is shocking at first. You ask yourself if you did the right thing by turning the car into a rocket... Did I ruin the "feel"? Is it still a 914? Oh noooo....and then...you want more power. But start with stock and go up from there.

Chris hit the nail on the head- even Subaru admits that the intake and exhaust on a stock SVX is very restrictive. Once you let the engine breath in and out, simple bolt on mods really open up a very efficient air pump without sacrificing dependability or driveability at all. These engines are very robust and should last a long time, well past 200k if treated right. And I'm not talking about driving like grandma- punch it and hang on!

Yes,iam sure i would be happy at 240,but iam sure those are at the crank numbers ,so if i i build to say 300-325 that is close to the 275 range of RWHP,I only awant to build it once and then drive till they take my license away,.lol...
