dmulally's pimpin' Imp

[dmulally]

Now then. I dragged this home so I might get it running in situ so I can see how it runs with a standard box. The fuel is varnish and the shifter is seized but it's all good because the engine is seized too. 

@Adoom and @cubastreet just felt a cold chill go down their spine.

....that gearbox adapter plate. It looks very rectangular.

[dmulally]

The angle iron engine mount is pretty sweet too. 

I love that sort of one off engineering. Looking forward to seeing if it actually drives.

Did they hacksaw the front off the subie box and tig it onto a bit of plate?

To the left of the plate is hillman and subie to the right.

Going to be a right pain when it breaks as it will all need to be swapped over rather than punted into the creek like every other rooted imp box.

Came with a pretty sweet split radiator setup in the rear. 

Anybody know if it will be a problem having a filler neck/cap both front and rear? Thinking for the front putting on an 18psi cap and 13psi on the rear with an expansion bottle off that one. 

[Nominal]

18psi is a lot for a vintage radiator.

[Alfashark]

Are they linked?

105/120Ls had a thin piece of tube that ran from the top of the rad (up front), along the top of the front guard with a small bleed tap up near the base of the windscreen.  It drained into the gutter/channel that the bonnet edge closed into on the guard.

Foolproof for bleeding.

[dmulally]

The front one is a modern alloy radiator. I could weld it shut but not sure I want to go down that one way street. The 18psi is to keep it closed off. 

Rear ones look 80's or 90's. 

Front and rear will be on different circuits (front off the heater lines with an EWP in line) and rear two will be split and on the subie water pump circuit. So all with the same water but going down different paths. 

[Alfashark]

I'd just run the alloy one up front and remove the one in the back.

Keep it light and as simple as possible.

[dmulally]

Yeah furry muff. I suppose I could change it if it starts getting too warm. 

[Alfashark]

You'll be fine.  A home-brew turbo + Megasquirt on a 136 1300 didn't stress the small stock rad on a 120L, so a stock NA Subaru should be a piece of piss.

 Engineering porn straight onto instagram that.

So I got the engine freed up but the starter motor is frozen. Even tried hitting it with a hammer but nada. 

I might just drop the engine and try to start it on the floor as it's a pain trying to get to things in there. 

[yoeddynz]

I might have a spare scooby starter you can have. Not sure what those earlier engines have fitted.

Thanks. I'll send you some pics of what it looks like. It looks pretty cruddy though so I might give it a good clean first and see if that's all it takes. 

Also trying to sort shipping on these:

Seller is making it tricky to know a price however. Look at the questions:

This thing is yuck. I might give it a scrub first and then take a peak under the valve covers. The breather pipes are missing so looks like a lot of condensation/rust could have snuck into it. 

Soon find out!

[dmulally]

Anybody got any hot tips for rebuilding starters? I sandpapered the round copper looking thing and the three things that go around it but nada. 

It pushes out but doesnt rotate. If I rotate by hand it is very stiff. 

[cubastreet]

Easy.  come get one of mine.

[dmulally]

@yoeddynz when you could be bothered, are you able to show me the engine mount setup you have for the datto pls? My one is reasonably clever and uses the original mounting point but I know the LVV cert man won't like it being angle iron and not boxed.
