Dash back in, dare I say, for the last time


Made/modified the throttle cable bracket. I also trimmed the throttle pedal stopper (both ends) to get full cable motion


Mounted the catch can


Finally got the PS line fixed in place. This turned out to be a long job as I couldn't torque the bolts to spec without twisting the P-clamps. The solution was to cut some recesses in the spacers.




Did a bit of head scratching and decided my battery is going here


Started filling holes in my dash parts

Thanks. Yep, getting very close.

Need to get an exhaust made up, remake PCV system, mount battery, fit rad (polish/paint shroud), sort heater pipes, few wiring things (rev light, horn, rear fog), make fusebox mount, wire Racelogic TC.

Continuing with all the jobs i've been putting off.

I dropped the sump and resealed in as I had a little leak.

Fixed my main loom, oil pressure sensor and map sensor to the bulkhead.



Drilled out and re-tapped the bolts holes for the front wing as both bolts had sheared off.

I do have a new problem though. Where I located my AIT sensor the huge clip hits the bonnet. Not sure what I am going to do about this yet. Options are to sink it deeper into the intake or finding an alternative lower profile sensor.



Fitted the new PCV piping

Sorted the rear fog light out. I rewired it so that it activates from what was the front fog switch on the center console. I didn't bother taking pics, but it was relatively involved. The previous owner had rewired the DS reverse light, which was fine, but the wire wasn't going through the bulkhead grommet so I sorted that.

I also found my OEM IAT sensor which is lower profile so will hopefully sort my issue with it hitting the bonnet.


Next I spent some time trying to wire my reverse light. That was a fail. I need to look at this again as I had an auto. I have removed the park/neutral switch so I think the wire I soldered the reverse switch to is no longer getting power.


I also setup my HP EFI outputs to activate the cooling fan and the revers lockout. Both ended in fail. Not sure why neither are working at the moment.

Been getting through some more of my job list recently.

I sorted the horn wiring. For some reason I wasn't getting continuity between the relay and the horn switch so the horn was constantly on. Not sure why, but the wire goes through the airbag unit. Luckily I had threaded a few wires through my loom so I used one of the spares and bypassed the airbag unit.

I also sorted the reverse light. It took me a while to find the correct B/Y wire, but it's all sorted now.

I fitted my new straight terminals to the ignition leads and fitted them. I had planned to run the wires behind the headers for a nice tidy look, but decided against it. There was no point risking them melting and they aren't too unsightly in the normal location.



Next was fitting the rad, cowling and intake.


As always is the case with things, each time a sort a problem another arises. In this case the top rad hose doesn't really fit. I have ordered a 135 degree hose in the hope that I might be able to use two to form an s-bend.


I tried to fill the diff with oil but it turns out the drain plug has fused to the diff bastard! I haven't tried heat yet, but I am letting it soak a little first. Hope I don't have to piss about ordering a new rear cover.

I figured out why the reverse lockout wasn't working. I completely overlooked the fact that the ECU isn't getting a speed signal. So now I have to wire my Dakota Digital to the VSS and ECU input so that I can configure a speed input that can then be used to trigger the VSS lockout below 5mph.

SO what's left to do?

1 - custom exhaust
2 - heater piping
3 - Sort diff plug
4 - wire vss
5 - wire traction control (maybe after it's on the road)
6 - Plug gauges in (want to finished painting them first)
7 - fire it up and let it warm up so that I can let HP EFI do it's magic

Radiator/intake cowling looks pretty boss with the wrinkle finish.  Very nice.

Had a chat with someone I may get to do my exhaust. He is going to come over and take a look at the car and discuss options. Unfortunately he is now on holiday for two weeks.

I had no luck finding anyone that can bead roll my ali pipes so I hacked some crimping pliers. Not perfect but should be fine



Unfortunately, soon after that I got the grinder out and tried to modify the pliers so that I could bead the 16mm pipe I got for my heater lines. The tool is now ruined and I still need to bead the pipes :)

The tweaks continue:

Got the seats back in the car and both wings on.

Resolved the top coolant hose issue. Turned out to be pretty simple using a 135 degree silicone hose, 45 degree ali joiner and trimmed down the existing 90 degree bend.


Also spent too much time making this small little bracket to hold the broken bonnet cable in place

Got the car started again at the weekend. After a catalogue of stupid errors and a bust sensor, it started throwing the belt at idle so that's a pain in the arse. Not sure what I am going to do about it yet.

Anyway, fitted new stoptech rear disks

Fixed the problem with the fans not coming on. Turned out to be two wires switched at the relay.

I drained the fuel in case it was that causing the car to run lumpy. It didn't look too bad as it was coming out, but as the petrol can filled it started getting pretty black. I hope it's just where it's been sat for 10 months. Last time I looked the tank was spotless so I am doubtful it's corrosion. Maybe I need to get a new seal for the fuel pump hat.

I spent a little time trying to figure out why my belt was getting thrown. It's not easy to tell but the pulley maybe on too far. Perhaps I ordered the wrong part number? It would be a massive pain in the arse if I have to swap it.
