Well I bought the cheap one available from coolparts on ebay with a 2 year guarantee for our Eunos and no problems after more than 4 years and in daily use.
Have recommended them several times and no issues to my knowledge.
Up to you if you want to spend more:-)
I would add that MX5Heaven and MX5Parts list extensively on ebay - not sure about MX5City.
Nippart radiators are perfectly adequate; look identical to OE, except for a slight different drain plug. ILM radiator might be “better”, but do you feel that the MX5’s cooling system is marginal?
My 1.6 has a Koyo radiator, similar aluminium effort to the ILM car. Indicated temperature is always cooler that my 96, over the left side of the gauge scale (not cold). Heater always feels a bit feeble compared to the 96 (which has a Nipparts radiator, fitted about 10 years ago). A car running colder than what the manufactrer intended is not necessarily a good thing. I can see the need if the car is put into a stressed state, such as sustained high revs.
I bought the cheapest ally radiator I could find from eBay. It cost £108. I usually avoid this type of thing, but I thought “ what the heck”.
i received a beautifully packaged item with welding good enough to win awards. It’s 52 mm wide with a twin core. It fitted perfectly and has performed 100% since installation.
i agree with what you say about eBay. 90% seems to be utter rubbish. But obviously a diamond creeps through occasionally.
Thanks for the input guys & my apologies for not replying earlier - ecologists work long & strange hours in the summer months - bloody bats!
But I’m going to go with the 42mm core IL Motorsports one, yes a bit dearer but I want the best I can afford/am willing to pay for, plus there’s the 10% discount & I’ve £100 about to turn up - went missing as Ladbrokes tried t pay my winnings in to the wrong (closed) bank account so it’s been floating about in the ether for a few weeks!
So all in I’ll only be shelling out £52 new for it (taking my £100 winnings in to account )
Now about those induction kits - see seperrate post
The best is probably the original Mazda, not a cheap aluminium radiator offered by IL Motorsport, using some unknown supplier (probably parts of it are from China).
Well I fitted this today, had to take a small nick out of the corner of the fan cowling - but that was more to do with where the hose clip was, everything else was fine - apart from the one school boy error:
Bigger capacity radiator so it’s obviously going to take more coolant DOH! So in short never had enough - toyed with the idea of topping it up with distilled water as a stop-gap but decided against it - will get more coolant tomorrow & then I can be off & running.
