May 11, 200421 yr OK---Is everyone ready for a EA81 intake converted to accept a side-draft 40MM carb???? I present for your viewing pleasure (drum-roll please) FRANKININTAKE!!!!!! MHAWWWWWWWWWWWWWWWWWW!!!!!!!!
May 11, 200421 yr Author Cut the stock manifold very carefully--you can still see the watercross-passage (used it to keep it all aligned)--mandrel-bent tubing & a a old weber/dellorto intake off eBay + lots of cursing---& lots of grinding:grin:--still need to finish the rear inner areas a little--but I needed to quit for the night---
May 11, 200421 yr Man that looks like something right offa Monster Garage.. So is that pointed so the carb will face forward or rearward? Would look perty phat, poppin the hood and seeing a pair of chrome stacks stickin out...
May 11, 200421 yr If you put it behind the engine, it would make the intake alot closer to the firewall. Then you can add some stacks to it and stick them through the hood. Should loo nice further back than stock Do you already have carbs for it? and how hard would it be to make another? -Brian
May 11, 200421 yr Looks functional, and that's all that matters. Welding aluminium is a black art. Throttle response should be crazy quick when you get the Delortos' in tune. I had a 70 240 and getting the SUs' tuned was a pain, but when they were right, so nice. Jay
May 11, 200421 yr Looks good, but I (and this is a shocker) agree with Brian, it should have pointed to the rear. Far less chance of getting water ingested into the engine that way, as well as why Brian suggested it, the stacks will increase torque. I've always wanted to take a MPFI'd engine and install dual downdraft Webers on it. Subaru had such an engine in an EA81 form, it was used on a gen I RX.
May 11, 200421 yr Guys, from what I've read in other posts, it will point to the rear. That little mounting thing on the left runner faces the rear on every sube I've seen at the PAP.
May 11, 200421 yr may not be needed but maybe think about a small passage between the 2 intakes to help balance the intake pulses? it would be different if it was a true independent runner setup but with the suby head desighn its not possible unless of course you did it with mpfi heads.. but then it wouldn't be a ea81 very nice work btw
May 11, 200421 yr Author The intake is set-up to point the carb to the rear--I've planned to use the '97 Outback hoodscoop to blow cold air on the carb (a cold-air box is in the works)--The spare tire left long-ago--The intake I got off of eBay was a old Cannon unit--there is a cast-in balance tube right at the mouth of the intake---not many people know about balance tubes anymore-- As for the carb--I have a 40MM Dellorto with 80mm chrome ram tubes on it:grin: The manifold was a real B**** to make--most likely have $300 or so in it in time & materials-- Thanks everyone!!!
May 11, 200421 yr ehh what can i say i have a stack of performance books about 4-5 feet high i thought of doing a fuel injected ir setup but since i run turbo... but i think it would be neat to see a homebrew hilborn injection on top of a sube:)
May 11, 200421 yr I guess I'm too used to working on EA82s, I saw the thermostat housing (which on an EA82 is in the front) and thought the opening of the housing was facing forward.
May 11, 200421 yr that's awesome you should get some vids and sound caps of it up. I bet it sounds so cool with that carb and exhaust on it. do you plan on getting it dyno'ed?
May 12, 200421 yr Author Got the last of the grinding on the inside done today--mounted the carb & made the throttle cable mount--I've got to do some more bodywork on the car tomorrow & Thursday I'm taking the car back down to the shop to set-up the carb--weld seat rails on the '92 Honda Civic seats & the guys at the alignment shop are doing a 4 wheel after hours for me:)--got too much work to get done & not enough time until the first practice on Saturday--Sounds like the start of a racing season to me!!!! Wish I could tell the boss "I need two days off"---(fat chance!!)--so the car will be raced without the flares (no time)---but should be ready mechanicaly!!! To those who are interested, the cars page is-- http://performancebydesign.netfirms.com/subaru.html I haven't updated it yet--will do it after this weekend-maybe I'll have some good times to post:)
May 12, 200421 yr Oh no I am in love again... GREAT flair on the wheel wells! Scoop looks great! Who new a soob could look so smooth!? (except me) Nice Joshua
May 12, 200421 yr Author Thankx!!! The car is a Autocross/SoloII/Street machine--The plan is to toast some Honda boys with it-------
May 12, 200421 yr Awesome work on the intake....I would love to do that and maybe use some Mikunis! What did you use to cut the intake up/away from the original water passage? If you free up the exhaust, that thing should really rev....can't wait to hear about your success.
May 12, 200421 yr Author Used a power bandsaw, hacksaws, carbide rotary files & anything else I could find:)---Check out the pics in my older post on the exaust--thats the exaust shops work:grin:--sounds real sweet---
