Hi Everyone,
I am starting a new refurbishment project on my Coupe and thought I would post the progress on the forum as it progresses.

I have owned two other Coupes in the past (a metallic blue 16v and a red Trubo plus). Both of these were completely stock, but with my more recent cars being modified (a 600HP Supra and a 550HP SL55 AMG) I was always likely to go for a modified Coupe if I got another one smile

So last year I spotted Nigel's modified moon grey Turbo Plus for sale on the forum, and after an inspection and test drive I bought it and drove it back to sunny Belfast cool

As Nigel has already carried out the performance modifications, my project will be to prepare the car to be my daily driver for the next 20 years.

The main work will be:

1. Eradicating any rust (which is now just starting to appear on the underside and wheel arches).
2. Refurbish the rear subframe.
3. Trace and fix an engine oil leak.
4. Change all the engine fluids, filters, belts etc
5. Replace the worn Vibra Technics gearbox rear mount.
6. Full silicone hose set.
7. High flow catalytic converter (to pass emissions test at the official MOT centres here in Northern ireland frown )
8. Possibly an aftermarket ECU?
9. New rear discs and pads.
10. Fix air con.
11. Double din head unit.
12. Strip and repaint centre console.
13. Front and rear parking sensors.
14. Full respray in a cutom House of Kolor cobalt blue candy paint.

The car was left in with my mechanic on saturday and I have asked him to send me before and after photos as he progresses. So hopefully I will have some photos later this week.

To get things started here are some photos of the car before the works start.

Simon

Just a quick update on the car.

My Mechanic has finally started - he went off with Covid the day after I dropped the car off with him rolleyes

To date he has fitted the replacement gearbox mount and all the silicone hoses, and has traced the engine oil leak - it seems that the oil cooler is knackered so he has ordered a new one.

He has dropped the rear axle for refurbishment and is also going to replace the brake lines.

I have reminded him to send me photos and I will post them as soon as they come through.

I took a run over to see the car this morning and things are progressing well smile

Any rust discovered has been treated with rust converter and repainted/undersealed. The eifel towers were a little bit scabby but cleaned up ok.

The rear subframe has been dropped, cleaned up, new mounts fitted, and new brake discs fitted. New brake pipes will be required.

The engine has been checked over and a small oil leak was found at the cam cover. The cover has been stripped and resprayed and is ready to be re-fit with a new gasket.

The silicone hoses have all been fitted.

The replacement gearbox mount has been fitted.

A new cone air filter, cabin filter, fuel filter, oil filter and engine oil has been fitted.

The defective oil cooler has been stripped and a replacement ordered.

The front and rear parking sensors have been fitted, and just need wired up.

My Mechanic hopes to have everything finised by next weekend cool

The Guys have also been investigating the fuelling issue at idle.

My initial thought was that it was overfuelling, but the have tested the AFR and it is actually substantially underfuelled shocked

So we are planning to fit a piggyback ECU and doing a complete adjustment of the fuelling on their dyno.

The car is nearly finished now smile

The cam cover has been resprayed and re-fitted with a new gasket.

A replacement (upgraded) oil cooler has been fitted.

The internal dash trims have been stripped out for painting with the exterior - thanks for those advising on how to remove the strips.

The only thing left to do is fitting and mapping the piggyback ECU (which is due this week), and fitting the double din head unit (which will be done after the exterior re-spray).

Picked up the car today after nearly two months in the garage - delays caused by covid, family bereavement, and ecu chip shortages rolleyes

All the works went to plan and the piggyback ECU appears to have worked extremely well.

With the car on the hub dyno my mapper found that the original tune didnt appear to control the fuelling at idle leaving it running extremely lean. Then on boost it ran rich (9.5 AFR!) with substantial timing adjustments to compensate.

He has therefore remapped it by pulling a lot of fuel and easing the timing back. This has lost a bit of the low down torque (due to it boosing slightly later) but has resulted in quite a sizeable jump in top end HP and torque cool

See attached dyno sheet showing the before and after results.

He has fully painted the interior trims as his benchmark.

It is hard to see from the photo but the metallic silver basecoat should glimmer through the blue candy in the sunlight.

Clearcoat still to do which should deepen the colour further.

All dents etc have been filled and the whole car has been primed.

The door reveals and underside of the bonnet have been painted.

Next week the doors will go back on so the whole shell can be painted in one go.
