crazy D Posted July 7, 2007 Share Posted July 7, 2007 well i got this Ea81 block downstairs that ive been slowly tearing apart(and ifi ever get the damned thing apart) id like to do some mods to it. i was thinking of a delta cam, some 9.5 comp pistons, and then for the fuel its a desicion between spfi or a weber intake manifold for aircraft ready EA81. id like to know how much hp of each combo i listed (cam,pistons and spfi) or (cam, pistons and weber intake) and...is there anything else i can do....remember im a mechanic noobie and im very poor thanks for the help -Dalton Quote Link to comment Share on other sites More sharing options...
Phizinza Posted July 7, 2007 Share Posted July 7, 2007 Sounds like you know every sane mod you should do to an EA81.. I'd think somewhere around 100hp? If shes got good compression that is. Quote Link to comment Share on other sites More sharing options...
Jerry DeMoss Posted July 7, 2007 Share Posted July 7, 2007 If someone in your car is nice enough to squeeze a bellows with a long hose on it and direct it towards your carb, then I think that is an easy 10h.p. extra. j/k. Quote Link to comment Share on other sites More sharing options...
cubastreet Posted July 7, 2007 Share Posted July 7, 2007 Make sure you get the big valve heads, and you can also smooth out the ports with a die grinder or patiently with a dremel. Quote Link to comment Share on other sites More sharing options...
baccaruda Posted July 7, 2007 Share Posted July 7, 2007 it could be cheaper to swap in an EJ22, FWIW.... Quote Link to comment Share on other sites More sharing options...
crazy D Posted July 7, 2007 Author Share Posted July 7, 2007 it could be cheaper to swap in an EJ22, FWIW.... thats what i really want to do... but i dont have room for the legacy i need for parts soo Quote Link to comment Share on other sites More sharing options...
86BRATMAN Posted July 8, 2007 Share Posted July 8, 2007 All you would truely need from the legacy is the wiring, ecu, and motor. If you have some help you could get it all out in a day and scrap the car. Quote Link to comment Share on other sites More sharing options...

Caboobaroo Posted July 9, 2007 Share Posted July 9, 2007 ok here's another thought to throw into your pot... How good are you with tuning carbs? I remember you having some issues with the Hitachi and tuning a Weber will be easier but it will still need to be tuned right or else hesitation, poor gas mileage, etc. The SPFI on the other hand, is a basic drop on and go with very little tuning (like timing) but nothing else. If it were me, I'd go with the SPFI over the Weber if you don't feel comfortable with tuning it and get frusterated with not being able to get it tuned right. It took me foooorever to get my Weber tuned and jetted right om my '78 Brat but when I got it, it would smoke the rear tires off without even thinking about it:burnout: Quote Link to comment Share on other sites More sharing options...
