What are you up to Jon?

would like to take the easy way out of making a neat alloy adaptor plate to top the throttle body of an EA82 spfi inlet manifold - provide material and gasket and a few dollars to get a neato shaped plate to then screw on an adaptor to take a silicone ducting from LPG mixer......onto an EA81 already sporting EA82 Y pipe

Google 'water jet cutting' in your home town. They are everywhere

Yep, forgot to mention I found a few . Wondering about cost fear of small one off

But, I have a little drill press and a special cutter bit called a drill bit to get rough shape and some files. Time to dress up vices nasty corners to preserve fingers ..... will be quicker than getting a ' volunteer'

We get stuff laser cut all the time for work. 8 or 10mm plate aluminium things around the size your thinking usually around the $60 mark.

Doug

Angle grinder, die grinder and a few files should net a pretty neat job for only an hour or so of manual labour.

If it looks a bit rough, rub some grease on it and throw some dirt and it and it will look like its been there for years

Wouldn't match the rest of the engine if I did that

Thinking though, a rectangular plate with big hole in the middle should do just fine - otherwise the budget just keeps going ...I'm sure USPS share price went up last week

thinking drill press and lots of small holes, die grinder, some filing, bandaids etc

Or someone with a plasma cutter? Much more common = cheaper?

Found a guy (moir ) with cheap arse hole saw kit $20 @ a field day - useless at cutting holes in tin, mild steel plate, plastic and even timber - but ally plate - great !! Got the die grinder out and got carried away with someones suggestion of port matching - matched the bigger port up so now too big for adaptor - IMPCO A3-31 .

Got in some good practice for M6 1.0mm thread making - 5mm drill bit in drill press for squareness, correct size hole for tap, bit a lanolin and nice holes done. Just needmore ally plate now, for MKIII

Never used a die grinder on alloy before - best ever - never cakes up - just got silver snow through shed now !

Photos or it didnt happen

Working on MK3 - and it looks a lot more promising.Drilled and tapped the flange bolt holes first- in case they didn't work out, bit of precision measure, punch ,drill, tap to M6 1.0 pitch...... all needing to line up. The rest of it was centred around it. As with many adaptors - they have tapers on main hole, this one will when finished too ! The Subaru side of things is quite whacky, with a deliberate offset so a gasket goes only one way...

Pics later.....

This is it without showing actual detail of the work put in, see if I can remember to get some when I gasket it up. Has three way lot of holes to line up, down on to the throttle body and up into the A3 32 adaptor I found in my collection, it in turn bolts up nicely to the gas mixer. The third lot of holes are hidden and were to take another impco adaptor a3 31 to use a silicone bend hose for remote mixer mounting or from a turbo idea simmering away .....

I was able to get a pair of M6 allen head bolts, see one just to the right of the orange safety label - it goes through the adaptor plate from the mixer and secures into the throttle body housing - reducing number of threaded holes and bolts by two
My adaptor plate has two impco screws of funny thread description to the left of the orange label, with heads recessed in underside of plate, screw up into the impco adaptor, the impco adaptor has same deal, four recessed impco screws going up into the mixer.

Happy. Be moreso when i get to test it
