So after driving my friends 450BHP 485kg custom MEV Exocet, I decided to sell the MX5 and build my own light weight pocket rocket, but a Seven kit instead of an Exocet.

So, I bought this.

It has a 2 liter Zetec engine which I plan to mate to an RX8 gearbox and a Sierra Cosworth LSD. The plan is to fit a T2 Turbo and run around 350BHP, which should be enough to make things interesting.

A lot of work is required, and I plan to strengthen the chassis a fair bit, and use as much carbon fiber as possible to keep weight down.

Here it is parked at my friends house temporarily with his 1000BHP / Tonne beast.

How far did you get with the MX-5 in the end?

Exocets look fun. Seen a few at shows. Not pretty things but they seem to weigh sod-all and with so little bodywork the sensation of speed must be pretty high.

The first 5 before I sold it last year:

The track slag before I sold it:

Exocets are amazing fun. My friends is all custom built to his spec, extruded tubular frame, different suspension geometry, and the 1.6L turbo with ~450BHP on pump fuel and 660BHP on E85 makes it a lairy drive. It's silly fast. Like, making hyper cars look stupid fast.

Mine will be a little more tame, but should still put hairs on my chest. :P
 
I really appreciate the Miata base and actually like the rearward pinch in the chassis' styling, but I think they're desperately in need of a little more bodywork. Considered doing one but I'm not one for a ground-up project since my Beetle.

Mine isn't actually Miata based and it will be fully clad in bodywork. My friend is planning to get his covered too eventually.
 
949Racing 6UL's in the UK! Rad.

I've literally just sold them on. I only know of three other pairs over here at least in the MX5 scene, one being on the green exocet in the OP :)

Edit: I've just stalked you and realised who you are - I am pretty sure I follow you on instagram or a Miata forum :P
 
Haha neat. They've just come out with some Exocet specific offsets too, since the suspension geometry isn't 100% the same as a Miata. I know the guys over at 949 really well, and I know they get excited seeing their stuff on cars overseas.
 
Well, thats the last time I buy a car off of eBay without looking at it first.

The eBay listing described the car as having the Zetec 2.0ltr engine fitted. Last weekend we began work on the car and it became apparent immediately that this was bull:censored:... The engine mount brackets on the chassis didn't even line up with the car, the brackets themselves were just tacked in place, the chassis had been grinded into poorly and not welded up again and the whole 'subframe' that the previous owner had bodged together to attempt to make this engine fit was unbelievely unsafe. It was obvious the guy had had a go at making the zetec fit, realised he couldn't do it and tried to sell it on. The only reason we didn't notice this was because he told us the engine was loose in because he had to remove it to get his gearbox out. Unfortunately I am too trusting and have now paid a rather hefty price. I have opened a dispute with PayPal and although they agree with my claim, apparently they cannot retreive any money from him account which makes me question the point of me spending £50 extra for protection. Anyway!!! I am not a quitter! And luckily my pal is awesome at fabrication...

Here is the 🤬🤬🤬 engine mount brackets that the previous owner had 'fabricated'

Here is a video of my friend pulling the welds off after cutting the tubular section out...




The car came with a sheet stainless steel floor which weighed an absolute tonne, this was stripped out and there was found to be no chassis rails or anywhere to bolt the seats to, so this will need to be rectified before I put in a lovely carbon fiber floor.

I think the picture above, my friend is starting to regret helping me with this project.

The picture below shows one of the rear coilovers. Anyone who knows what they are looking at here will spot the issue. The coilover mounts should be facing the laser line, which is where the bushes align on the suspension. The tool who had built the car this far, however, was clearly unaware of this. Also, the mounts themselves look way too weak. Another thing to rectify!

And on with the build!

So this is currently where the car is at the minute. The engine is sitting on blocks of wood on the floor, but it is all aligned with the differential and is exactly where it needs to be in the car, which makes our job of welding in a subframe a hell of a lot easier. I have just ordered loads of box section and tubular mild steel to refabricate the front end and strengthen the rest of the chassis too, so when this is done it'll be strong enough to handle the ~300BHP from the turbo engine. Work resumes after christmas :)

So right now it looks as though you should have just bought some chromoly and made it from scratch! Sorry to hear about your misfortune but hey at least you get the chance to make it to your own specifications

Yeah I was pretty gutted but at least now it'll be much stronger than it would have been before my hand was forced. It's just the loss of money that annoys me hah.
 
So, I managed to get a few days on the car this week to get a subframe fabricated and get the engine in.

We ran box section down each side of the engine to create a platform for the engine mounts to sit between the box section and the outer frame, as seen below running alongside the gearbox and engine.

15780657_1385772104774607_6440831074295941810_n.jpg


After that was tacked in position, we then put in a small piece of box section either side of the engine mount between the outer frame and the new box section to create a platform for some plate for the engine mount to bolt to, as seen below....

15697380_1386211264730691_2786086442176881788_n.jpg


Once both sides were complete, the engine was removed and we finished welding it all up....

15727037_1387197164632101_2022586120999621150_n.jpg




The frame was flipped to weld underneath.

15727359_1386211258064025_4612590045764169947_n.jpg





Here is a before and after picture from when I bought the frame to now:

15697230_1386211891397295_8087230392759041656_n.jpg



Once welding was done, the engine was put back in and it located like a dream.


15780925_1387197224632095_9095391167175398956_n.jpg



And there we are!!! A new subframe for my powerplant to sit, the car is now officially 'fitted' with an engine, not whatever the previous owners idea of fitted was. Next job: Gearbox mounting and driveshaft made, pedal box, seating and steering column. Stay tuned!


Also, bonus picture.....

If you're looking for a spare 2.0L Zetec, I know where you can find one. ;)

And in Huddersfield you're only a few miles from where I am building this :)

I'll get her closer to completion first but the plan is to eventually either rebuild this engine or build another one up to take more boost. I like the sound of 600BHP / Tonne

Great progress!

Cheers dude :)

Oh, whereabouts is it being built?

Not sure if a Mondeo engine would be any good for you, but you're more than welcome to have it if you want it. Runs and pulls fine, just have no idea on the mileage since we bought it secondhand.

It's being built in Barnsley until the chassis is finished, then it'll be home in Norwich.

I'd take it if I had the room, if you've still got it in a couple months I'd have it!

Ah, cool!

Well, we're not planning on stripping Bruiser until the weather gets better (around spring) so I'll let you know when we do start.
 
Holy crap, this thread has turned eventful since last time I visited!

For me it's a good example of why I never have been and never will be keen to buy something previously built/modified by someone else, unless I'm completely sure of its provenance. You're never quite sure whether someone has done something properly - be that as simple as installing an induction kit or as complicated as building a car from scratch.

Glad you've been able to turn it around.
