Still over due posting videos but a few things to update.

1st, Hawks helped me re-weld the exhaust for the NB, or rather the cat for it as the car was given back to me with it being an inch too short and about 3 degrees out in angle. We noticed the resonated pipe that's been in there in the mean time also was done badly and strained the header to fit. We managed a far better job, in a warehouse, using stands, not in a workshop, with a lift and band saw like when it was originally fabricated :rolleyes: . So big thanks to Hawks for that, the car is much quieter now and I can sort of pass an MOT.

2nd. Got married. The NB supercharger pulley shat itself the weekend before ofc as it was meant to be our wedding car. The Celica stepped in to replace it (getting the dress in the NBFL without her in was impossible by itself). This still isn't resolved. The pulley won't bind up no matter how many or few shims I use so I can't work out the min/max specs and shim it correctly in the middle. On the plus side, the Celica now has the GT body kit and spoiler.

3rd. Just got back from a day at Donnington GP circuit. It's sooo much fun, definitely my new favourite track. The car was great, super fast and barely any issues. Got asked 3 times whether it was turbo or supercharged :ROFLMAO:. This is the first time I've done the circuit with the 6 speed and as I said would likely be the case in a previous post way back the 6 speed is a game changer for Donnington. More choice of gear and better able to keep it in the power which makes all the difference in the uphill sections. Granted the GP circuit has hairpins in it but I was able to use 2nd-5th, unlike with the 5 speed where it was just 3rd or 4th. If I didn't already have the turbo I'd be happy to leave the car as it is, it's not the fastest thing on track, but it's quick (quicker than a k-swap mk1, 2 turbo mk2s, a DC5, R53, etc thanks to silly tyres and brakes), I can do 30 mins sessions at a time, and drive it home.

AR1s once again did great in the dry and the wet, really worth the money. I think they've got about 1-2 more track days left in them but not looking forward to forking out the money for more. I did struggle with understeer in the dry though and I duno why. I let the pressures down a bit in the front and then tried to soften the front suspension a bit but I couldn't dial it out. I'm not entirely sure whether it's in part due to too much rear grip, but I'd rather not get a stiffer rear ARB and sacrifice rear grip just to change the balance. I think a decent front splitter would work well so might try that, I'm just worried about it going the other way and ending up too tail happy. It might also be that I'm just asking way too much of the tyres.

Now on EBC Blues in the rear as my stock pads were low enough they'd likely die during the day and I didn't want to be swapping them at the track. A lot of dust but otherwise no issues. I am starting to find I'm not that happy with the DS2500, they're a good pad sure, wear and feel are good, but I feel I would like something more aggressive and better. I've a set of RP1s I'm looking forward to trying, or might put the Blues in the front as well so there's some balance with temps and friction coefficients.

The pilot and throw out bearings are both beyond fucked now. Totalmx5repair are going to sort it out at some point soon for me so should be fine. It's odd they didn't even last the drive home from when they were put in. Clutch judder is still bad, still unsure why, the old exedy was fine and had no issues so it's also unlikely to be the flywheel, will get them to have a look when we do the bearings.

I fixed the previously mentioned issue with the 6 speed getting into 3rd gear, the nylon cup was pretty worn and with the short shifter I have it can't have any play as it's so precise.

Congratulations on your wedding, I hope you had a great time.

Donnington is my local track, I’m looking forward to getting back to track days next year.
Glad your making good progress and the Celica is looking good.

Looked like a great day at Donnington, the track didn’t seem busy. The trio of BMW’s weren’t hanging about!
It was a busy day tbh, open pit lane and 85 drivers although the track didn't feel too crowded most of the time, I think partly because it was the GP circuit so 2.5miles long. Most people seem to a few sessions in a day, maybe 4(?) so that helped spread the field a bit. I tend to try and get my moneys worth, and with OE power, 60mm rad, and 300mm brakes I can comfortably do a 30-40 session, back in for a 15 minute cool down then back out. I did about 230 miles on track, cica 90 laps (2.5 mile circuit). I tend to get about 2 sessions then am in danger of fuel starving.

Glad you are happy with it all! And congrats on the wedding!

If you fancy Donington national in December, it's the Mx5 only day with MOT track days, should be a good one again, even if it is a bit late in the year 😂
we both booked in on 12th Dec for the "last" session of the year for MSV... wish I'd known there was an MX-5 specific day.. :(

which provider is it through/what date?

EDIT: found it Donington Park - Sunday 11th December 22 (mottrackdays.com)

Not sure the track car will be in a state to do a track day in Decemeber. I currently have the Celica booked in for the 12th, the lack of baffled sump really worries me though, and while it is pretty capable it is heavier, and on track I really lean on my uprated brakes and tyres a hell of a lot, neither of which the Celica can compete with.

But your Celica has Wilwood (lites?) calipers no?
They are small and thin pads, the dynalites really are a bit crap tbh, it's also on OE discs so likely will struggle to manage the heat. Will see what the weather is guna be like and how I get on with the NBFL

Someone I know was selling a 43k mile VVT engine so I thought I'd grab a spare given the beating the track car gets. The celica again proved why it's the best car I've owned and managed to fit the entire thing in the boot. Big thanks to Hawks for saving me again and acquiring an engine crane/helping lift the engine out the boot.

The engine looks pretty good, no leaks, nice and clean, turns over super smooth by hand, etc. The plugs were a little sooty but I think we can excuse that given it's averaged 2k miles a year for all it's life and has done about 300 in the last 2 years. For my reference the plate of the car it's come out of is SD03 TZA.

So clean.

Do all VVT blocks have a sandwich plate on the oil filter?
its a 1.8 thing, started with the mk1's (unsure if all the mk2's have them or if it's just a 1.8 thing 🤷‍♂️ )

its a heat exchanger, uses the oil to warm the coolant (or coolant to warm the oilo_O ) then transfers oil heat to the coolant as the main coolant radiator is (huge) more efficient than a conventional oil / air radiator😜

Thanks, I have both a VVT and non VVT mk2 and never noticed haha!

Had a bit of a fiddle today and put the ev14 injectors into the supercharged car to try and see if the rx8s with my Ecu/settings were responsible for my poor idle (above 1100rpm, mid 13s afr only). After a bit of tuning I was able to get AFRs in the mid 14s and the idle down to 900rpm. Closed loop idle control was also much easier to get set up. It appears that my ECU just can't drive the rx8s well enough and that's been my problem. Guitarist has rx8s with an me221 and we have the same settings and his is dead on 14.5 afr with only +/-0.1 so I know the injectors themselves are capable of idling well. Mine were cleaned and flow tested before they went in too so I know that isn't it. Even with the ev14s my afr still moves about a bit so it's likely the limit of the ECU. Either way I'm glad to have found the cause and that all I need to do is buy another set to resolve it (these 640cc ones are destined for the track car). I was really shocked to see bofi has increased the price by £100 in less than 12 months though!!!

If anyone is after a set of flow tested rx8 injectors feel free to dm me (440cc).

Poor start up is likely something else like cranking pulse width. I just had to up mine massively now the weather is colder. If you pm me your valves I can give you an opinion.

Maxing at 210bhp doesn't sound right either, at 95% duty and the advertised 420cc (mine flow tested at 440 cc) they should support about 300bhp according to deatshworks.

Yes I believed the RX8 injectors should have been fine. My injectors were just from a guy who breaks RX8’s. Not tested, no idea on mileage of the car or anything. Since then I’ve done more reading and found others who had issues with a bad set of RX8 injectors.
I’ll send you some photos now.
