I recon 5w40 is perfect for a UK-based 'hard driven' mk1/mk2.

Are you going to fit a knock sensor ?

You'll need some two-wire shielded cable and a bosch donut sensor, along with some 2 pin JPT connectors. I'd also recommend some nice black nylon sheathing. I Expect DIYEFI will support knock.

Thank you, will do a bit more research into it, tuners been in contact with the DIY-EFI guy so hopefully get something sorted.

Thanks Howard, we're going for 0.8Bar/12psi-ish, are you thinking of going EBC in the future?

Yeah the DIY-EFI uses the same connection, but I think it's my wiring that's the issue. Do you know what bph you're running with the 12psi? Night and day to the supercharger setup power wise?

Collected the car on Saturday, forgetting there were train strikes, so what should have been an easy journey turned into a bit of a faff. left the house at 10am, didn't get back till 5pm, the tuners only an hour or so away by car.

Anyway, where do I start, car still needs to go back to him for final tuning, the mx5 IACV is proving a bit of a pain, the mk2 crank sensor is working a treat though - it starts every time without excessive cranking. Still need to fit the: bonnet vents, 2.5" exhaust (which finally arrived after 4 weeks of chasing the guy). I'm dropping voltage under load so he suspects my alternator is on it's way out, so I'll get a new one from mx5parts. It's doing inconsistent things with my AFR's when hot and cold. It looks like the original 30 year old unit and I did try running a dying battery for a while, so no surprise there.

It's fitted with a manual boost controller for now, running 0.8/0.9Bar, first impressions: it's sodding quick, like most speeds feel quick in a 5 but when you actually go quick....it feels daft/silly speed. It's rained all weekend since I got it back, so I've not had a chance to test what it can do on some roads I know. The GT2554r runs out of puff after about 6k so it does drop off a bit, but there is literally no lag, none, squirt and go type of stuff.

The turbo noises are absolutely daft, especially the Forge BOV, potentially too much for what I'm after, but hearing the turbo start to spool is addictive, I've had other turbo cars before but this is another level.

I've since changed the coolant and the oil to 5W40, going to daily drive it for a while, he's back onshore the end of November so I'll get it back to him with all the snagging list completed.

Oh and I checked, 70mph is at roughly 3500rpm, it's just my tacho needle it fitted in the wrong place from when I did the dial faces.

I'll get some pictures/videos when I get a chance/it stops raining. Meanwhile I need to go relearn how to drive this thing.

don't bother on the inlet er (exhaust side of the cam cover) side unless you're tracking the car. :-) the simplest solution is a hose to somewhere away from the exhaust in case something lets go and oil flies out.

Got some pictures of the mk2 Crank sensor fitted up in position on the mk1 block, I'm not sure if he notched the sensor or the oil pump, but it fits in nicely, he's(tuner) ran the wiring along the COPS and down which seems to be working well. MK2 crank pulley fitted which accommodates the trigger wheel thickness. You can also see the BOFI lower rad hose, which I would recommend as it created a lot of space for intercooler piping, for anyone FI.

Tuner advised, during a pull my voltage was dropping off, sign of an alternator on it's last swan song, which is not bad for what I assume is 30 years old - this one came with the replacement engine so we'd never removed it. Bought a new one from BOFI and set about removing the old.....can now confirm the worst bolt to remove on the car so far is the lower alternator bolt! I'm surprised it didn't snap, 2 hours to get the thing out - Disclaimer: I did everything from the top as I refused to put it on jack stands - alternator does come out you just need to remove your throttle body. Since the TB was coming off anyway to swap the IACV for a spare, happy days. Said bolt, you can see the threads on the end aren't really threads anymore:

Old alternator vs new:

I've not yet refitted it as whilst I was waiting for a new bolt, I started on the Spiked Performance bonnet vents. Not too bad to fit, I think I've cut the second out a lot better than the first but the vent flange, some touch up paint - will hide a multitude of sins. I used some Dremel Speedyclic discs and a grinder, I need to tidy up some of the internal edges with some trim if possible but it's gone better than I thought. Maybe pick up a spare bonnet in the future. Anyway, simple enough to fit, just apply the vinyl outlines they supply (trick is to wet the bonnet and the back of the vinyl), position to the measurements on the green tape and squeegee out the water.

Cut the top layer with the Dremel and then came back through with the grinder on the under bracing, then finished with a file (handily it's aluminium). I got some dust sheets to cover the car and I'm glad I did, surprising amount of mess from 2 holes.

First hole, you can see where I got a bit grinder happy:

2nd holes a lot better finish:

Then it's a case of trim to line up with the green tape and drill some holes for the rivets, only done one so far as I wait for the touch up paint on the other side to dry.

Quite subtle on a black car, sure they'd stand out more on a different colour, hopefully they make a difference on the under bonnet temps, next step would be the intake box. I might put some gold tape under the bonnet above the turbo, try alleviate the paint (and it'd look good). My intake side catch can has just arrived, which seems a bit better internally than the exhaust one I fitted, it's about sizes with a 330ml coke can, so I might try fit it to the strut brace - similar to how I fitted the EBC or to the charcoal canister bracket (if I can find it!), the non return valve hasn't arrived yet, I might get a barb fitting (10mm?) to the cam cover unless I can find my old knackered PCV to drill out. I do have some oil build up behind the throttle body, that's been there since before going turbo, so hopefully this resolves that or reduces substantially.

Will update once I'm a bit further along.
