The PAS unit is essentially a stock steering box with some hydraulic pipes coming off it. No real size difference per se.

The Elford unit is stock too. I don't think Elford added any extra heat shielding to the steering box or brakes so wouldn't be overly concerned. But having said that, rotors put out a lot of heat so it can't hurt. The trick will be keeping it neat.

Looks great btw. Nice to see those parts getting used. You hooked it up to the speedo ok?

just see how she goes ian without the heat shield. maybe wrap some heat resistant stuff around the steering areas
which may become affected.

the cold in the UK should balance it out while she is driving along.

just changed the engine oil in my rx8, the k&n oil filter was welded on and very little room to get at it
as it's at the back of the engine. but luckily they are smart and stick a nut on the top, so a few turns
with the vice grips and its off, new filter on, oil in and she purrs up so nicely :)

so understand the tight space etc alright, they really cram everything in for a small engine.

30 miles short of 95000 so i'm pre-mixing and going to change every 3k from now on and see how long touch wood
the renesis engine will last before a rebuild.

it's the hard hydraulic lines attached to the steering box that are the problem, they made the steering box assembly as a whole just that bit bigger and wider when I was trying to manhandle the turbo/manifold assembly into position past the already installed inlet manifold...... the differences are seen here....

Elfords installed a heat shield to the brake servo, here it is fitted to the bulkhead....

Heat shields wouldn't be needed to protect a manual steering box but it's the lines on this one that concern me a bit.
Apparently these turbos can glow red when the've had a proper thrashing which may affect the pas fluid as the lines are so close to the turbo.... it's designed so that the steering fluid is cooled as the lines pass across the engine bay in front of the engine mount..... a hot turbo would maybe negate that?

I dissected the KMH speedo and took the speed sensor out and put it into the mph speedo..... time will tell if it works again.

Oh cool. Hadn't seen the servo heat shield before.

Wrap the exhaust and maybe run reflective tape on the fluid lines or fit a shield over the exhaust manifold if you've got space.

I wouldn't be overly concerned if it took the heat from a 12AT.

yeah, good point, I'd forgot it'd come out of a turbo car. There wasn't a shield when we took it off the car was there?
I've got some polished stainless sheet so I'll have a bash at making a shield out of that.

Just factory shielding on the turbo itself. Similar to 13BT design.

Mind you, the Elford unit sits much further back closer to the firewall and steering box to allow room for the SU.

Just shield the turbo as much as you can.

some type of foil reflecting wrapping around the pas fluid lines then?

like the ceramic heat tiles on the space shuttle, sure they have shipped them to museums,
ring up nasa and see if they have any spare ones lol.

but something heat resistant or paint the steering lines in a heat resistant paint?

Your memory is better than mine! When we started to strip it, I took a load of photos of the pas and ac and just found them...... you can see the heatshield on here....... plus the turbo seems further away from the steering box than on the Elford.....

Not true. It sat in my garage for a few months before I sold it so I got to see it a few times. :lol:

Fascinating set of pics there, Ian. I've never had a chance to see an Elford turbo setup off the car before, what a ... err, quaint bit of kit! What is the pipe union on the top of the aluminium heatshield bit for? That wastegate setup's like a part off an old traction engine or something :shock:

As to the heatshielding issue, well I would to be honest! You could easily wrap the hydraulic lines with something like this http://www.demon-tweeks.co.uk/motorspor ... m-sleeving sheathing. I've used that on the brake lines on my FD and it's lasted pretty well. You can even get a version with velcro opening so you can wrap lines that are a pain to remove and thus slide the wrap over. Get hold of some Nimbus heatshield for making plate shields, it's really easy to work with and very light; http://www.nimbusmotorsport.co.uk/ProdS ... &CATID=252 can work it by hand to fit into the tightest of places. It might be easier to wrap the turbo mani and downpipe with some Dei-style bandage http://www.designengineering.com/catego ... technology though that cast manifold's a gurt big lump, perhaps not the easiest thing to cover!

From experience on the FD, turbo heat control makes a massive difference to how well it all works, and give the other components around it a massively easier time. If you can do it, I suggest you should. Plus wrapping the downpipe etc will make the turbo run more efficiently, keeping the gasses excited and therefore faster, and so on.
