Here's my previous project:

Panda Racing No.1

A year after selling it, and owning 5 cars in the interim I decided another MX5 would be a suitable replacement car to get me to the train station and back. Last week I therefore found myself schlepping around the M25 to Essex in the rain to look at a sorry looking 1.8 incorrectly advertised as a V-Spec that I hoped was actually an S-Special.

I collected it and after inflating the tyres (the rears were on 11 and 13psi) I set off home. It doesn't have the 112mph limiter my 1.6 had. It runs out of legs at 122mph though (speedo and TomTom in agreement at that part of the dial). It's woefully underpowered and it feels quite baggy compared to my last one. Remind me, what is it I like about these cars again?
Image


I'd say the 1.8 engine isn't as sweet as the 1.6. Where the 1.6 enjoys being wrung out, the 1.8 prefers to make progress on the slightly higher torque it produces and you gain nothing from screwing the last 500rpm out of it. I'm hoping the more manly 1.8 drivetrain will last better on track than my 1.6 did though as that ate clutches, brakes etc. for fun.

My journey home averaged 29 MPG. Pretty appalling for a small car of this nature, especially when my M3 would have made circa 33 for the same journey.

Anyway, Sunday I had time to give it a quick going over and evaluate what needs to be done to it. I nearly always forget to take photos of what cars are like when I get them so tend to only have the 'after' pics. So here it is on the drive in the state it arrived:

Image


Image


Paint is very tired, car has ingrained dirt and hasn't been cleaned properly in years. It will look a million times better just having some TLC and a proper clean, sorting out the number plate bracket that's fitted upside down and a few areas of the plastic front and rear bumpers that have crazed paint will get re-painted. Good points are that it appears to have no rust on the bodywork (which is why I bought it) and the hood is new and watertight.

Wheels belong to the previous owner so they'll be going back to him. Will be good to lose the oversized budget 205/50/15 tyres that are blunting the car's responses.

Popping the bonnet revealed years of dirt and grime.

Image


The whole car seems to have been neglected so its no surprise to see a filthy engine bay. Washer fluid was empty, oil was on minimum and coolant was below minimum. At least it's mainly standard without lots of shiny tat or an awful induction kit or anything. Only areas of note are a broken dipstick handle (the history for the car shows this as an advisory on its first MOT in the country) and a broken clip for the bonnet stay, meaning over time the bonnet stay has been sat on the radiator top-hose, making a small but noticeable indentation in it. I'll get a new clip and replace the hose.

Poking around it in the daylight it's in quite a strange state. It's almost as if it has just arrived at the docks. It's got all the Japanese licencing info in the windscreen still, there are random JDM stickers here and there and the interior is filthy, and unbelievably still has Japanese parking tickets and other odds and ends in it.

Here's the important sticker saying it's an S-Spec:

Image


...and the inside of the boot lid holds clues to a potential previous life as a trackday/club racer/road warrior:

Image


Anyway, as it started raining I pulled it inside to give the inside a clean and sort out:

Image


Sticking my head in the footwell to hoover it out I found this:

Image


An original JDM flare.

Image


Image


I can't decide whether to set it off for a bit of fun or to sell it. Are these rare and would there be a market for it?

Mazdaspeed gearknob fitted. Not to my taste but possibly worth a few quid to someone? Will be in the For Sale section soon.

Image


The Nardi Torino that's fitted I do like. I'm tempted to keep it 'in stock', but may well sell that on too?:

Image


Image


Image


This is the funniest thing in the entire car:

Image


A 'carbon' ashtray.
Image
Apparently it's the one Takuma Sato had fitted to his F1 car so he could have a crafty bifta during qualifying. Will be going in the For Sale section too.

A bit of CSI digging about while cleaning the inside gave further clues to what the boot stickers had hinted at. One of the stickers was the Safety21 logo. Digging about I found the rear deck fuel tank cover had been tin-snipped and beneath them, covered up very well with metallic tape was the evidence of where the rear stays of a rollbar had been mounted.

Image


Image


Image


Then looking under the floor, holes where the main hoop had mounted were visible, but there were none where the front legs would go on a 6-point cage. Therefore, I'd assume in Japan it had a Safety21 4 point rollbar.

Image


Anyway, I gave the interior a thorough clean, removed all the unnecessary stickers. Pulled the Nardi off and replaced it with my Momo. I also climbed underneath and had a look at the suspension. The rear Mazdaspeed coilovers were backed off to their softest setting and that was that. It's now much more pleasant inside and with the back a few clicks softer it drives better too.

So far I've bought some proper chairs for it and some scaffolding to protect my head in case it falls over. Today I'm going to buy some coilovers and some wheels. It'll then need a front lip, an alignment, some brakes, harnesses, a hard-top, some paint and a thorough stripping / lighten-ing. Hopefully will get it on track by November. Will be doing it as a rolling project though, commuting sideways in it everyday and seeing what it's like to live with as a daily drive.

Nice result mate and be great to get a passenger ride in it.

Very nice! Videos required now. :p

Great figures there, those cams work very well, nearly a 30hp gain over the previous spec seems money well spent to me.

This must be one of the highest specific output N/A BP's on the road in the UK now?

VERY nice result, you must be chuffed to buggery.

Sorry about the pissed up rant last night, I need to learn how to handle my wines.

How's the cold air intake coming on? Was it dyno'd on open trumpets?

I'm interested as to what Dan is thinking on minimising the torque dip.

Respect due to you for pushing the n/a envelope and in the process creating IMHO the best roadster on here.
 
#1,506 ·
Cheers guys. As Dan says all the runs were with the bonnet down and the airbox and filter on. I haven't yet made the cold air feed for the airbox so it was swallowing whatever air had been through the hot rad and from the heat-soaked engine bay. I imagine on the move it's getting cooler air and making a bit more power and hopefully when the cold air feed is in place it'll experience similar performance gains as Clive's race car did with the lower IAT.
 
#1,509 ·
Thanks Clive. Not sure on next steps - I want to get rid of the flat-spot as currently an up-shift puts you right in it. I think to make a noticeable amount more power then it needs rods and ARPs so it can rev. If I'm doing that then it makes sense to go oversize high-comp pistons too. As great as a stroker would be, and apparently the torque increase is fantastic, the cost makes very little sense. The Maruha 2.1 kit of crank, rods and pistons is about ÂŁ5k to get to the UK.

Am at Brands tomorrow - I only have slicks or old, bald Ao48s and rain is forecast so will try to keep it the right way up. I'll try to grab some video.

Honda K24 swap cost's about same ÂŁ5k and from there, sky is the limit as 300whp can be had, something you can only dream with N/A Mazda engines. So stroker makes no sence money wise.

I agree. I don't think I'd K20/K24 swap into an MX5 though. I think they make much more sense in an Elise/Exige. In fact I can't get the idea of one out of my head. :ph34r:
Horses for courses, I guess, but for me it's the perfect car:

Bolts to the MX5 box so no propshaft/PPF issues to contend with either. And it retains the OEM steering rack location. Win Win.
