BiTurbo228 Posted November 26, 2015 Author Share Posted November 26, 2015 Quoted from Jonny-Jimbo Anyone know the weight of an Impreza diff? Yep weighed one that I got off eBay as part of stockpiling for future projects.Subaru R160 (the one without flanges): 26kgIf you're weighing up for a conversion you'll need a modified backplate and a bracket to fit between the diff and chassis at the front end (oh, and another bracket to attach the leaf spring to). All of which I don't have... Quote Link to comment Share on other sites More sharing options...
Jonny-Jimbo Posted November 26, 2015 Share Posted November 26, 2015 Yeah, I know it's not a case of just sticking the Scooby diff in, but I'm thinking for the Herald-ish thing I'm building up it's the way I'm likely to go as a Subaru diff with an LSD is much cheaper than a rebuilt Triumph diff with an LSD in.

Definitely. Apparently the difficulty with that is finding a Scooby diff with an LSD in it. I've read around about people buying up diffs that were advertised as LSDs that turned out to be open when they got them. Def ask for a picture of the internals before sending your hard-earned to anyone...Also, most have viscous LSDs (which IIRC only work with one driveshaft longer than the other, although I don't know where I pulled that piece of information from). However, my favourite people at Quaife have a torsen LSD listed for a 2000 Subaru Impreza which is an R160.Will be interesting to know whether I'm right or wrong with the viscous driveshaft length thing...When you do come to swap one in, make sure you post up how you sorted the rear plate/mounting bracket. There's a chap in Aus who made up a batch of alloy rear plates with the Triumph mounting brackets cast in but I think they're all sold.I was thinking that I've got some 3mm plate, a hammer and a welder and that with those tools you can make most things Quote Link to comment Share on other sites More sharing options...
Jonny-Jimbo Posted November 27, 2015 Share Posted November 27, 2015 I'll probably model something up in CAD, then get a rapid prototype mould made so I can cast a back plate and then get it machined... Or possibly do as you say and make it out of 3mm still plate welded up - can do it super-sexy too with my tig welder haha. Quote Link to comment Share on other sites More sharing options...

Nice i've got to start playing with my tig welder so i can extend my inlet trumpets. I'm doing tuned length ones either 15mm longer or 290mm longer to get different resonances.Might be tricky to get the 290mm ones in the engine bay though...

Jonny-Jimbo Posted November 29, 2015 Share Posted November 29, 2015 Won't that work on a 'centre-line' principle, so, although not ideal maybe, it'd mean you could curve them like some of the old BMW intake manifolds etc. Quote Link to comment Share on other sites More sharing options...

Clearance on the inner wheelarch would be marginal I was thinking, especially with a filter.Can't do any of that til I lower my PI inlets though. Need to make them level so the injectors clear the bonnet.Oh, and weld on some bonnet mounts because I wasn't a fan of the stock ones...

BiTurbo228 Posted April 13, 2016 Author Share Posted April 13, 2016 Well, £160 later and I've got myself a set of fibreglass doors.Can't say I'm overly chuffed however. Weighed one and it came in at 9.6kg complete with hinges, door handles, external latch thingy and 2.5 sheets of sound deadening.Considering that earlier in this thread we ascertained that a bare steel door shell is 9.5kg that's not quite the weight saving I was hoping for.At work at the moment so I can't strip it and find out what the shell alone weighs, but hinges are 400 grams, and the latch plus doorhandle should be about a kilo combined (maybe).That leaves a total weight saving of roughly 2kg per door.I'll have another look tonight to see if the doors are bulletproof-thickness fibreglass...

BiTurbo228 Posted April 13, 2016 Author Share Posted April 13, 2016 Hmmm, getting confused now. Bob Dunn says here that 'standard doors are approx. 17.45kg' but not certain whether that's Vitesse or Spit doors...[Sorry, link no longer available]Also, something my google-fu is failing me on. JohnD's Silverback & Son thereof...Spitfire or Vitesse? Quote Link to comment Share on other sites More sharing options...
John Bonnett Posted April 13, 2016 Share Posted April 13, 2016 John Ds car was/is a Vitesse.I have two stripped down GT6 doors. Would you like the weight?

Jonny-Jimbo Posted April 13, 2016 Share Posted April 13, 2016 Try and find Boyse's Aston Martin Silouette car, that is a carbon kevlar bodied car, looks like a normal Aston, but I remember seeing some trick hinges and latches. Lots of Billet aluminium, which would save weight a lot, could always make some hinges up with aluminium plate and a bolt for a pin etc.JohnD's cars are all vaguely Vitesse type cars, not Spitfire.

JohnD Posted April 13, 2016 Share Posted April 13, 2016 No help to you, except as a target, especially as Vitesse doors are bigger, but my GRP ones weighed 5kgs, with furniture (OE hinges and locks) but no glass or plastic windows - they were hung on the screen surround.That weight was achieved by the inner shell - complete, no cutouts - being a single thickness of random matt, with some reinforcements for the hinges and lock, and the skin being a half thickness random matt (you can tease the two surfaces apart) with a layer of GRP tissue on the surface. The result was rigid, but the skin was like a sheet of stiff paper, so I stiffened it with an inner layer of paper honeycomb, with another layer of tissue inside that. Still came in at 5Kgs.John Quote Link to comment Share on other sites More sharing options...

Exactly the same a Dolly Sprint alloy (although you've got to factor in the weight of spacers for those if fitting to a Spit or GT6) Quote Link to comment Share on other sites More sharing options...
