Sometimes it doesn't need to have a huge turbo for me to give a good old 'second look'!

Audi 80 in lovely condition, with a little modernization!

TR Autos over in Yeovil, removed the old K-jet fuelled 1.8, and replaced it with the well proven 20v engine, from a later Audi A4. They performed the engine conversion in its entirety, with the exception of the management.

I was fortunate enough to be entrusted with this. :-)

Maxxecu Street, custom harness with the ECU sat inside the vehicle. All the usual goodies with some modern injectors and an upgraded turbocharger, giving a nice safe 200bhp on tap.

The car is fantastic, it totally reminds me of when I first started driving, many moons ago! There were plenty of these in the road back then.

Loads of original 80's coolness on this car. With the bonnet shut, you'd never even know it's running a more modern engine to keep things a little more sensible in this modern world! Originally this car had 112bhp.

Absolutely loved this one!

Turbocharged X300 XJR!

A video going into detail on Alex's turbocharged XJR. I chat about the car and the conversion that has been completed.

Quite a few questions answered on this interesting car, with thanks to:

I realised I've not thanked the usual suspects for the help with my 'rear end', a few weeks ago!

A good while ago, I designed an alloy rear frame and tank holder for my old Jag!

I cut the boot floor and surrounding areas out made a cardboard cutout of my design, and set about it!

It lowers the CG of the car significantly. Removed about 26kg from the vehicle, and allowed me to carry more fuel if I wish. It also has mounts for the BGW now straight to the chassis, which has been another job on the list.

Also some significant changes to brakes and lubrication system, We've even got decent paddle shifters on the old girl now, but that's a post for another day! 🤣

Thanks to Howard at Aller Engineering SW Ltd for laser cutting my drawings, and turning a little idea onto reality for me yet again.

Thanks to Simon Dowell & Mike Wells-Burr for a couple of Sundays they lost cutting my car around... Again. 🤣

Thanks to Adam Hunt from Noath Precision for again, turning my drawings into a reality with my oil bypass AJV8 block!

Thanks for James King at JEK Fabrications for sticking all my stuff together, and bringing the whole deal as one!

Thanks to Tom Robinson & Jack Robinson from Swallows Jaguar - Swallows Racing for corner weighting and sorting the Geo on her after all this cutting about!

Get to test it at Castle Combe Circuit with the Jaguar Enthusiasts' Club for one of their epic track days next week. Watch it p**s down, as I've got slicks on it still! 🤣🤣

Anyway, Libby has told me I can have carbon doors and tailgate now! So that's a few Sundays over the winter sorted! 🤣🤣

I always forget how many hours goes into a high grade harness.

Look at me, I made a reel!!

Really happy to be able to announce that we are stocking the new DomiWorks Engineering AJ6/AJ16 8HP adapter plate.

These allow our AJ6 based engines to run the unbeatable 8HP gearbox. There is simply no automatic that touches it.

For the last 12 months we've been running the 8HP on an AJ16 on a different adapter plate we'd been developing. Upon hearing that Domiworks were making one (as I mentioned in one of my videos), we decided to just wait for the Domiworks one to be released. As we've seen and used many of their kits now, we know it'll be absolutely bang on. We've recently used a couple of the Jaguar V12 kits for 8HP conversions, and know there is nothing near the quality.

Naturally, because we've had our little X300 test mule, we've known the relevant harness mods and have offered this into our AJ16 harnesses for the last 12 months! There are at least 15 harnesses out there 8HP ready!

We already stock the oil converter to go from the Jag box, to AN10 oil pipes.

The MaxxECU AJ16 kits we build control the 8HP70 straight out of the box! Buttery smooth gear changes, actual torque reduction, actual throttle blip on our FBW packages. Just like the OEM.

The 8HP70 gearbox is a glorious piece of kit, and is the talking point of many modified cars at the moment. The MaxxECU control allows various different gearbox modes, shifting points, torque control, live modification from within the ECU software. After using the test mule X300, I can tell you that the 8HP suits the AJ16 perfectly.

We've got a number of V12s now running the MaxxECU 8HP system, I’m sure the AJ6 based kits will be even more popular!

We were the first to develop a specific AJ16 harness/ECU system years ago with Swallows Jaguar - Swallows Racing. We wanted a system that was a direct plug-in system - one we sell to a client, post to them, and get it running from often the other side of the planet. Our aim has never been to provide a cheap system, but more a complete solution. Offering better than OEM smooth engine control using all the OEM sensors. On board datalogging, and class leading onboard wideband control allows us to tune the ECU remotely, with ease. More recently our systems go out with modern LSU5.2 lambda. 90% of our clients this year have opted for fly-by-wire. Giving modern reliability, and again, complete control!

Digital speedo conversion, keeping the retro look & feel of the Peugeot Gti!

I use James' K20 converted Pug 309 Gti as a base to convert his mechanical style speedometer to a newer digital style, keeping the classic looks and feels of the OEM cluster.

Naturally these are fully programmable, and can be used in the 309 and indeed the 205gti.

I take it one step further, and have new guage faces made to replicate the originals, only 'all the way up to 11', well, not really, 10, but still! I'm really happy with this conversion, I hope James will be too!

I apologise for not having uploaded anything of late to my socials, I'm spinning plates constantly at the moment. Lots of exciting things going on at the moment, lots of development for some very well respected companies that will be revealed probably next year now. Some SERIOUS hours put in, but with some seriously cool cars!

Thanks to Uncle Spike here for sorting the bracketry and physically getting the speedometer to fit into the OEM cluster. Thanks to Stef for sorting me with some spare clusters for some Beta runs! Thanks also to James for using his car as a Guinea pig!

Massive congratulations to Jordan and his team at Yellow Peril Racing.

Going home with a well deserved result at the Isle of Man Hill Rally.

1st in class and 6th overall, extending their class lead in the British Cross Country Championship.

Jordan is a lovely guy, that genuinely deserves results like these. We can see the work that goes into these machines, the absolute abuse they take requires constant maintenance and repairs.

This absolute weapon runs the BMW M62, coupled to the more and more popular 8HP gearbox. Naturally, all married together with the Maxxecu!

We look forward to following team 'Yellow Peril', and thank them for keeping us updated.

Been waiting for these to hit the mat!

The absolute perfect ECU for a V8!

The perfect AJV8 solution! Can't wait to get building!

On the website this evening!
