Best check out how much a decent T25 can be had out of an S14a then as I've seen them for a lot less than £400. Given they will do a range from 180 to 280bhp happily compared to the 200 to 240 or something the crappy KKK thing with it's cracky cast manifold can handle, I say they're crap compared to a good T25.
Making up your own inlet is time and some cash in materials, depends how much you can find a tig welder for but if you get stuck I know of one that works for about £25 an hour, so about £100ish for that.
Exhaust wise you might be able to use the standard manifold and a flange for ultra budget, but I'd use an S14 fancy or even standard manifold and lop the flange off for a new one, so you can get that with the turbo for £250-300ish for a recently refurbed unit.
Engine and rebuild parts with the 16XE crank if you wanted to drop the compression a bit, about £600 or so (engine 200, parts £3-400 and a crank say you had to get a bottom end to get hold of, £100)
Then a good AFPR, management and a good mapping session is the major expense really, probably about 1500+ for all that.
So that puts you at about £2500 or so plus odd consumables etc.

A T25 out of a 15 year old S14a is not going to be decent imo

As above. I looked at the compressor maps, cost, availiability and reliability issues of both, and for the range of power you can work an x18xe1 turbo to with limited mods, the T25 came out on top for availability, reliability, cost and power potential/suitability.

So a vxr turbo/mani for £400 is going to be cheaper then?

According to my maths £250-300 is a lot less than £400? When I was looking at prices I actually saw one sold on a manifold for £180 so that's a conservative estimate. If you factor it in the 2-3 replacements with cracked manifolds over the lifetime of the car (Which you can't replace, they are part of the turbine housing) which is quite common with increased performance standard VXR turbos, probably something to do with that power range I mentioned earlier being exceeded, it's a hell of a lot less.

By the time you get a custom mani done thats going to be over £400 for sure
Havnt seen loads of reports with cracking like the early Z let mani either

So that mani will bolt straight on to a 1600/1800 head then? Im thinking not, therefore the mani will be useless
