Steptoe's photos Posted October 8, 2022 Share Posted October 8, 2022 I cannot say that I have seen this concept done or even discussed in 20 years of internet stuff. How should you make an old carb EA82 perform better ? Well, grab some turbo heads and inlet manifold, or XT all came with mpfi .... I think this was a plain old NA as you can see my past efforts to plumb coolant lines for a turbo from the temp sensor for gauge port. That project was put aside at some time, like all my EJ conversions I now need to wait for engineering suppliers to open on Monday to score some countersunk M8 to secure the adaptor plate to the existing TB holes, and some M8 studs to secure the Weber 32/36 DGV-M It is pretty convenient how the various mounting hole sets give each other some decent room. I will have to wait to see how clearances go to work out an air filter set up - certainly won't be using the standard air filter and housings that most use. I think it pretty poor that the PCV hose fitting is almost entirely covered by the air filter element in all those applications I have seen. I will most likely go remote air box with plenty of room to plumb in some breathers for crankcase using the remote filter adaptor if still available. I am making the adapter up myself old school way. CNC would be the way to go for sure. If anyone else has done non standard carburettor conversions to these mpfi heads, please share Link to comment Share on other sites More sharing options...
Steptoe's photos Posted October 8, 2022 Author Share Posted October 8, 2022 Once I remove the top face of the inlet manifold for the secondary bore there is still ample face to seal with a gasket against the adaptor. Removal will also give full room to breathe into the plenum and I have just a small amount to remove for the primary bore. Link to comment Share on other sites More sharing options...

That manifold work looks great, and the paint job sets it off nicely. I guess this isn’t done often due to the need to swap heads for the dual port intake.

Steptoe's photos Posted October 8, 2022 Author Share Posted October 8, 2022 (edited) My first EJ was 1.6 NA , sat around too long, in the way - scrap. Next EJ is a suspect EJ22 supposedly was fine before car was rear ended, yet the oily exhaust port appearance suggests that all is not so good, seeing as other stuff sourced from same mate has been described as good, was too loose a description for scrap. EJ20 sits in a Brumby with AWD 5 speed, stuck in unworkable conditions, needs wiring diagram or spxxdyefi ECU or a donor I have my eye on. Still got two EA82 sitting about to use up :) One is fully rebuilt OS turbo, the other just needs assembly using new OS EA71 high comp flat top slugs. EJ might be exciting but think I need to get EA82 stuff out of my system The Weber bug bite marks still present too after a bad experience with this particular carb cause it to be shelved 26 years. The choke flaps jamb against casting from new . Dremel sanding drum to casting avoided staked screw work. Chokes now fully close and will swing in the breeze. How that got past any manufacturing quality control I have no idea .I did a very successful and reliable Weber conversion to a 1200cc Corolla some years back and never done EA Weber and this idea came to me last weekend as a way to break away from dwindling LPG Propane supply issues and not go EJ to get back to wet fuel The green was my thing with Ford LPG dedicated engines getting a green rocker cover - green wrinkle finish was it? being the inspiration to make my dedicated LPG engines look different to the others with green rockers and inlets. Webers can also be turboed with a special intercooler style hat and rising rate fuel regulation Edited October 8, 2022 by Steptoe's photos Link to comment Share on other sites More sharing options...

Cheers Bennie Once-upon-a-time enthusiasts were willing to swap heads and manifolds/carbs for performance gains on sixes and eights, so why not a flat four ? The power gains may not be there but I would hope responsiveness, torque and the best possible fuel figures once/if I can tune it with a tailpipe analyser.

Apples and Oranges on this one I reckon Steptoe - with the sixes and eights it is an easier job with the block still in the car compared to a boxer. Plus the sizes and eights you’re talking about are most likely not a sensitive to a HG change as the Subarus are And sadly on many fronts we throw away items rather than repair them these days, even though the item is serviceable with some time and effort. I see this as double edged - many people aren’t skilled enough to perform the repair so it’s reliable again and those that can, it isn’t worth their time when you can get a complete NEW unit generally a little bit more coin.

Steptoe's photos Posted October 10, 2022 Author Share Posted October 10, 2022 This continues to be do-able, sort of can't wait until all the six stars align and it is ready. If anything, these pics might inspire other EA82 tinkerers to consider or even beat me to it. An original TB gasket will provide and outline trace for the underside gasket and I think a normal Weber base gasket will do for the upper gasket. I can stash this with my EA82 spfi intake I was modifying to stuff onto an EA81 with an EA82 turbo exhaust and turbo. I might have to get onto that idea before LPG becomes too hard to get ! I have my eye on a few old Brumbies about the place, looking a little unloved, so who knows. I have more different engine combinations than I have cars to put them in Link to comment Share on other sites More sharing options...
