My 3B Coupe project - Total rebuild

[Error404]

S2 ones are progressively wound Andy.



Looks like you got sold something else

[djh]

not good, thats two sets that look completely different.

Does look like stock 10v/20v springs that can't take the extra weight of the s2 setup.

[4WheelDrifter]

The H&Rs for my S2 are blue. My cq20v H&Rs were red. That maybe another clue.

[AndyP]

I bought them from a forum member. They are definatley not S2 springs, I can't even find the part number on H&R's website. anybody know what an AU006VA is off??

I guess I should have checked this before I fitted them

Oh well, spanners out again!!

[djh]

got a link to the for sale thread?

nothing comes up in a google search. Probably spax going by that number.

Not sure this of any help:

Good find twoqu

how they can say springs are good for 10v/20v/3b i'm unsure as the weight differences between them is quite a bit

[martinjs]

S2 H&R's are 29939VA/HA

[AndyP]

Plan B

[djh]

Good option

are they bambridge one's?

What shock's you going to use, koni's?

[AndyP]

Yes, they are Kev's. Dampers are Bilstein B6.

Just reading up on what springs to go for now.

[A80Avant]

Ask Brian, but I'm going for 225 front and custom 315 rear on the avant. Make sure you get no less than 9inch otherwise they will bottom out

My car has had a mis-fire for some time now and at first I thought it would be an easy fix, plugs or HT leads at the most. It’s intermitant and only shows up on high boost, if I leave the boost controller on low boost ( 1bar ) it’s fine but turn it up to 1.5bar and the mis-fire appears. So far I’ve changed the following componants:-

Coil
Plugs
HT leads
Distributor
Rotor arm distributor cap
Fuel pressure regulator
Also had the injectors back on the ASNU machine and they checked out ok.

The other weekend I tried another set of HT leads, and whilst I had the inlet manifold off I noticed this






All the inlet valves that were shut had a puddle of oil on them. The car has always used a lot of oil but I’d put it down to the JE pistons needing a bigger clearance than stock pistons. So I’m now thinking that the oil consumption is fouling the plugs. So when I got in from work on Friday I pulled the head off



Considering how much oil the engine consumes, 1litre in 600miles, it was not nearly as bad as I thought, The pic above was taken after I’d cleaned the pistons. The exhaust manifold was spotless as was the turbo hot side. The piston tops and combustion chamber had a good coating of soot, as did the valves.






Looking at the plugs and turbine you’d have thought it’s running lean, but according to my AFR gauge it runs a little rich, a little over 11:1 @ WOT.
Everything has now been cleaned , the valve guides were within factory spec so I replaced the valve stem oil seals and the head is now back on the car. Still loads to do but hoping to have it running for next weekend, and if the suspension is finished, I’ll give it a test drive.

Coil over conversion is almost done

Would have got all 4 legs welded but I ran out of filler rods.


When they’re all welded I’m going to get them blasted and paint them with POR15. New springs arrived on Saturday ( I’m going with 250lb/9” all round) so it should be a simple re-build and re-fit, oh and wheel alignment AGAIN. Fingers crossed this time.

Have you left the front steering arms the same andy or dropped them down for going lower. When mine was done we dropped them slightly to help with keeping the arms straight.

bloody hell mate...that would have been nasty if you hadn't sorted that before "you know when".... at least you have finally got to the bottom of it sooner.

looks like your well on your way to sorting your coupe.....
