dude_4_sale Posted June 29, 2007 Share Posted June 29, 2007 anyone know a way to put a bigger injector on a 94 loyale? or any other way to get alittle more power out of it? im putting a turbo on it and running low boost with intercooler but will be awhile before i do it. just wondering if theres any other little improvements able to be done?

faithless88 Posted June 29, 2007 Share Posted June 29, 2007 The engine is made for economy, so far other than the turbo is make the throttlr body a bigger one and put a bigger exhaust. Other than that not really sure what else to do on it. Link to comment Share on other sites More sharing options...

Other than that not really sure what else to do on it. Larger throttle body or no, the intake and exhaust ports, siamesed as they are, simply don't flow much air/fuel.. turbocharging is the only way to overcome this. You are turbocharging an SPFI vehicle? two plus two are not equaling four here. To turbocharge a SPFI engine, you would need to use a standalone engine management system like MegaSquirt, and basically build the entire turbo/fuel injection system from scratch using factory and non factory components. If this is in fact your plan, then you may be the first to try it.. I have certainly never heard of such a vehicle. As for a higher volume fuel injector, thats another thing I have never heard asked for. I am sure that somewhere, there is a TBI hitachi injector of similar design that flows more.. but I have no idea if it would fit into the subaru throttle body or not. In any case, the stock SPFI computer will not run a turbocharged SPFI setup, nor will a turbo computer.. the turbo vehicles were multi point fuel injection, and there ARE easy solutions for larger injectors for those vehicles. Sorry if I was a bit pedantic, or sounded arrogant.. but I am just trying to answer your questions. Link to comment Share on other sites More sharing options...
Skip Posted June 29, 2007 Share Posted June 29, 2007 very well stated Daeron he may be thinking of using one of these electric charger What say yea to the?? ;^) Link to comment Share on other sites More sharing options...

Actually that's not *quite* accurate. First, it has been done - but with an EA81 block. Rguyver had quite the interesting setup on his lifted hatchback. Among other things it was an SPFI EA81 with turbo and NOS. Of course few here remember that rig as it was quite a few years ago - when this place was still on EZBoard.... The problems (I have questioned him in person about that particular build) are numerous. The biggest drawback for *you* will be the SPFI's 9.5:1 compression - that alone will make it crack heads, blow head gaskets, and collapse ring lands, etc. The EA82 block and heads are simply not suitible for turboing. The EA81 did handle it - but it has a carbed compression of 8.7:1 and does not have the weak heads, and uses studs to mate the heads intstead of the inadequate bolts used in the EA82's. He told me the SPFI did actually handle the turbo fairly well, but when the manifold pressure went positive under full boost the computer would go a bit nuts. To offset this he installed a second injector above the TB. It wasn't the greatest setup in the world, but with Nitrous I'm sure it moved like a deamon under boost while sipping the bottle. I would imagine that possibly MegaSquirt could have improved the charactaristics of the setup immensly. The SPFI injector already flows a massive amount of fuel, and the second injector he used was really only because the computer didn't understand positive manifold pressure so the thing would lean out too far. It's important to note that this was not a street vehicle - it was primarily off road only. Also important to note that he now runs a WRX powered Brat. Sadly none of this really applies to the EA82 - it simply will not hold together using the SPFI block and heads. So really not worth the effort or time when a reliable, more powerfull EJ series engine is availible for relatively cheap. GD Link to comment Share on other sites More sharing options...
dude_4_sale Posted June 29, 2007 Author Share Posted June 29, 2007 i have read on a few other threads of ppl putting larger weber throttle bodies on the loyales. anyone got any info or links? Link to comment Share on other sites More sharing options...
86BRATMAN Posted June 29, 2007 Share Posted June 29, 2007 You've read things about people putting weber carbs on their cars... Not a good idea if since efi is more efficient/ Link to comment Share on other sites More sharing options...
mikeshoup Posted June 29, 2007 Share Posted June 29, 2007 You've got the wrong engine for power there buddy. If you want big power, go with an EJ. You can get power cheap out of an EJ and it'll be more reliable. Link to comment Share on other sites More sharing options...

Weber makes no such beast, and you have not read this. You are mixing up carbs and fuel injection - they are two totally different, and incompatible animals. A Weber will no more work on your loyale's fuel injection than a ball point pen would work for cutting hair. GD Link to comment Share on other sites More sharing options...
daeron Posted June 30, 2007 Share Posted June 30, 2007 A Weber will no more work on your loyale's fuel injection than a ball point pen would work for cutting hair. GD Mind if I use that analogy in my own life? thats great... BTW, I KNEW that somehow you were going to come out and tell me i was not 100% correct.. I think I must've read about Rguyvers vehicle once or something. and I have NO IDEA how i spelled ALL OF THAT out, and failed to mention the compression issue.. high compression, NA motor + forced induction (MAYBE under 5lbs of boost, but thats worthless) == blown motor, in many possible ways. It is not a "will it happen?" it is a "when will it happen?" and unless you are a TOP NOTCH engine builder, the answer is soon. If you re use a block that already has 100K+ miles, then the answer is VERY soon. Link to comment Share on other sites More sharing options...
