It's definitely the case that forging ahead with a solo project like this has been a very long drawn out and expensive process. However, a bigger turbo does not always mean more lag...my car now has significantly less lag and a lot more midrange than before. I'd guess I have around 280bhp, and it's always there ready to use just by pressing my right foot down harder.
The big issue is getting an ECU and a map. Unless something has appeared on the market in the last 4 years, a Haltech is the only option. Then getting it mapped (well) is the expensive part, because no "stock" maps exist so everything is done from scratch.
Now, if there is a group buy and everyone buys identical hardware then the cost of the map can be shared between everyone, with just a top-up map required for each car. But it would also depend on everyone having an identical system, with downpipes anda exhausts all matched.
Having gone through the pain, it should definitely be quicker for the next person, but not necessarily any cheaper, because it is the map that contributes the cost. But at least you'd know which parts to source!
My hesitation to recommend the turbo route definitely is more about the cost/benefit compared with the result; I'm very pleased with the result which gave me the performance I wanted without any downsides, but not with how much it ultimately cost.
My final bill was blurred because along the way I had new suspension fitted, new wishbones all round, a new intercooler, a turbo rebuild and carbon pipe fabrication, several sets of injectors and so on, but the mapping alone probably cost me about £2500, and that wasn't even what it cost them in time.
Overall the Radical now gives me the cheap thrills on the track without getting through a set of brakes & tyres each time, and the Aston has the road performance for general stooging around. Time has moved on, and I'm afraid the Elan doesn't get much of a look in these days.
