Picked up a MK1 MX5 Turbo a few weeks ago so thought I'd put up some terrible phone pictures for now :rolleyes:


Quite good fun, fairly quick, the odd rattle and not great on fuel... so as expected so far!

Where does the cost come from super/turbo charging engines? I see people quoting 7-9k to supercharge an E46, but when you look at the parts they can all be had for less than 1k, is it the remapping and RR time that costs or something?

It comes down to what parts, how reliable you want things to be and labour costs.

Can you genuinely get every part needed to supercharge an E46 for under £1k? That sounds impossibly cheap to me.
 
I've only glanced around, and I guess skidmarks is right about reliability, but a refurbed Eaton charger from a merc can be had for £500, intercooler cant be more than a couple of hundred? Pulley to bolt onto the water pump £50 or something, bit of tubing and a bracket probably a couple of hundred as it'd have to be custom made..er, ecu is the thing I guess, although I wonder if the standard one couple just be reprogrammed?

I actually know nothing about supercharging cars, as you may have guessed, but all the bits just don't seem that expensive, or difficult to fit. Obviously I'm wrong somewhere, but where are the big costs? Saying that, the parts list skid posted about comes to £1400 on it's own, so maybe 2k is closer to the mark.
 
The biggest costs for me weren't really in the headline figures. I picked up my M45 charger for around £250, the ECU was about the same.

Pipework even for a little old MX-5 was up into the hundreds - have a look at the cost of decent silicone piping! Then you have the intercooler - even the cheapest ones aren't cheap. Injectors, new plugs, pulleys, belts (at £10 a go these get expensive fast when you're ripping through them getting the whole thing aligned and tensioned properly). Bracketry is another thing that costs more than you think. Expect to pay several hundred quid in total for the parts you need and then a few quid more on various fixings and other bits and bobs to knock stuff up.

I bought all the key components for mine for around a grand but my total spend on that car was well north of £3k.
