There certainly is a lot to be said for the camerarderie and spirit of belonging. It's like a catalyst that binds us all together. In fact it's so extreme, no-one can start a topic on this site without it rapidly being overtaken and turned into a bloody sprint topic.

Now, sod off the lot of you and let me get on with my front mount project. :D

Hell, if it came to it Gerry, you could run in my car... :o (did I just offer that...)

Would deff be a step down from what you have with yours but it would let me see what mine is capable of :lol:

Ady, don't sell yourself short. I have all that power and driver aids for a very good reason. Wait tll the results are published before making assumptions. :grin:

Gerry, the clutch pipework you removed is in theory to assist bleeding the clutch, as it has a vent nipple at the top on the strut, and acts as a damper for the clutch pedal movement to the slave cylinder.

I ditched this in 2005 and it made a huge difference to the response of the clutch pedal.

ABS, i ditched before the start of last season, and combined with new braided lines, bias valve in cabin (worth it for balance of braking in wet and dry) it made a huge difference. I locked up once last year, at Oulton going into the chicance, thats it. Year before WITH ABS i lost count how many times i locked up. SUBARU ABS is sh1te!

Interesting pipe route!

Hi Steven,

I've noticed the bleed nipple in the clutch pipework but it wasn't positioned in the topmost pipe and Ive not actually seen anyone use it. Does removing that pipework make the bite more positive? More positive can't do any harm with a twin plate, I wouldn't have thought.

I never felt the ABS cut in after going to the 225 section tyres from the OE 205 section. I guessed the bigger footprint had better grip. The pump has been unplugged since March last year (except for MOT) and I've locked up a few times on sprints but not on track. I think sprinting tends to be more frantic than track driving and creates a bigger adrenalin rush, iyswim?

Pipework was simply a question of finding the shortest route with minimum bends. A sacrificial throttle body, welded to the original helped drop the angle of approach and now clears the bonnet even with manifold spacers.

My only concern is, the cold feed passes the hot rad. I may trry to fit a shield using a larger pipe section to deflect the blast, but it's all very close. I'm reluctant to 'blind' the section of rad and reduce the cooling but it may have to be done.

If you think it worthwhile, I'll post the pics on 22B but I'm light years behind what goes on there. :)

Yes, the clutch will have a more positive feel.

Put exhaust wrap round the intercooler pipe where it passes the rad. Mine ran within a few mm of the rad, and i never really had any issues with it getting warm.

I have some foil blanket wrap but it wouldn't survive the tight fit to get the pipe in place. Exhaust wrap is a good idea and didn't occur to me. I need to re-do the headers anyway.

Thanks Steven.

Friday was 'a get the odd jobs out the way day.' Well, that was the intention. It turned into a marathon brake bleed that had me thinking I shouldn't be allowed out unsupervised.

After an age of watching great globs of air bubble into the pot of expelled brake fluid, I decided to check why. The car was up on a 4 poster and I needed to climb up to top up the fluid every dozen or so pumps.

All was not well, each pump saw fluid squirting from one of the new pipe joints and no amount of tightening would stop it. Eventually, the end was cut off and re-swaged, re-fitted and all successfully bled (according to the feel of an unassisted pedal).

During the course of the day, I had a call about the ecu. They couldn't find a fault with it. Connected to the test rig, everything worked as it should. We scratched heads and I explained, as well as I could remember, exactly what had been done and all the circumstances relating to the re-connection of the ecu. Does the manifold have a good earth? he asked. Well yes there's a cable from the body of the alternator to the manifold.

But is the loom earth bolted to the manifold? Well, a good question. He explained that on this MY, the sensor wiring was was reduced and where, on earlier cars, there were 3 or four wires to some sensors, these had been reduced and commoned together. This apparently wasn't a raving success and any deviation from standard can cause problems. This multi wire earth connection must be secured to the manifold.

I managed to dig around in the knot of wiring at the back of the manifold and, sure enough, found the said connector, languishing, unbolted, hiding in a dark corner. Hooked it out and it now has a shiny new bolt fixing it firmly to a nice clean bolt hole.

A phone call to the repairer to confirm and we agreed that the only course of action was to try it again. The fact that the OE ecu had worked and that the ecu supply fuse was found to have blown were left unexplained but put down to the inexplicable.

As I was typing this, the postie has arrived with said ecu and I now have to wait until 10:00 when I can phone to see if I can get into the workshop.

Update later, I hope.
