Small update, couldn't find a t - piece the right size (32mmx18mm) to join that surprise pipe up to the bottom/water pump hose so I had one made

I already had the individual pipes so I cut and shaped the smaller one and drilled the larger pipe, then my friend tig'd them together for me.

Hoping tonight I can get all the water system finished

All plumbed in and filled up with water and antifreeze. No leaks so far ran the engine for a bit but it was too late and too noisy.

All coming together nicely now Ben, you should be ready in plenty of time for the good weather.

Have managed to map in the IACV on mine today so now it starts and fast idles from cold and the fast idle decays to normal idle as the temp increases.

I've left mine disconnected, I could wire it into the ecu but I'm not sure its worth it tbh.

Perhaps once its at mapping the tuner can make that decision for me

I had to turn the oil filter mounting so the pipe connections didn't rub on the alternator belt, I also found the wastegate was rattling, so tightened up the actuator arm.

Hey presto much quieter running engine.

Thanks Daveb666 for the suggestion of rotating the oil filter mounting, id forgotten they were bolted on.

Bloody well looks like it. I've got the ok from Allison and I've got most of the money for it.

Just need to try get the car up to running temperature tomorrow night and hope it's got no problems.

Bit of an update, I missed my original tuning booking due to a leaking clutch cylinder and a noisy clutch.

The leak been fixed but the noise is still there, I replaced the clutch bearing but its not that. So don't know what's wrong. I've given up trying to fix it, so it'll either get worse or whatever's touching when the pedal is pushed down will wear away enough to stop

Tuning is now booked for Friday 14th March, so i'll update then.

But it does drive fine and the water and oil system all works. I've also fitted an oil temperature sender but i'll update at the weekend once its all working ok.

Forgot I missed a step, Faired side panels... I also meshed them to hide the chassis behind.

Saturday morning I finished wiring in an oil temperature sender. Drilled and tapped the oil cooler line banjo bolt and inserted a smiths water temperature sensor. This was then wired to a switch along with the original water temperature cable.

Basically this all means that I can flip a switch and see what the oil temperature is, then flip it back for water temperature on the same gauge. Otherwise I've got to buy another smiths gauge which are over £50, plus £15 for the sender. That's fine but I'm running out of space on my dash!!

I'll stick a couple of pictures up tomorrow when I get to work as my laptops charger has had it at home.

So, the big day was on Friday! Tuning day at Bailey Performance!

Wow what a guy, Dale knows his stuff. I'm going to do a separate thread with a bit of a report with plenty more details.

But, the gory figures ars so:

272bhp and 308ftlb torque, it's was savage on the rollers and it kept spinning the rear wheels as peak torque come on. We ended up removing the splitter so it could be strapped down tighter.

I've not driven it anywhere yet, but Dale promises me it'll do 30mpg on cruise!

Happy bunny and no Major issues thankfully.

Great conversion

That power will be very interesting! What diff do you run?

Would have popped down for a nosey when it was being tuned if I had known, as I'm only just up the road from Bailey Performance.

Well, I've sent my ECU back to Dale so he can add the necessary bits to run my rev counter (diodes off the coil was causing interference)

I've found the oil leak on the bottom of the turbo and hopefully sealed it.

I bought a set of cooler plugs, but they turned out to be too big (14mm socket) to fit in the spark plug holes. Dale's going to send me some of the right ones when he returns my ecu.

I've bought a ford coil pack to replace the GM one. The GM one seems to be causing a minor misfire during hard acceleration.

I'll update with pictures once its arrived and all fitted

Well taxed the car and off out I went!! Holy poo the car shifts. Turbo kicks in low down the rev range. I had to really watch the speedo as I was speeding very quickly.

80degrees water temperature all the time and oil got up to 110degrees.

It doesn't scream off like the engine I had before, where your watching the revs go up ready to change gear. It's all about torque now, it just shoots off up the road like a scalded cat with no effort.

Big grins from me. Had the go pro running but it's was a bit dark,

Awesome!

Watch your oil temps though as that's quite high for pottering around

I'm not 100% sure that's correct. The temperature sensor I put into the banjo bolt for the oil cooler take of is not really the best place.

I'm going to relocate it to the sump and see what difference that makes.

I'm also going to drill a 6mm hole in the coolant thermostat to allow for lack of heater bypass. Which might explain why the fans coming on but gauge is only reading 80c
