4agte expert?

Hey everyone, i was wondering if anyone could help me out here...
I am going to start a 4agte conversion on my 86 soon (yes, i hav the money and skills to do it), however im not satisfied with the available information on suitable turbos, intercoolers and ecu's. Many people offer up good advice on what worked for them, but fail to mention how much work went into stuffing the cooler behind the front bar (e.g. what need to be cut, moved), wiring and tuning the ecu etc...
With the two other projects my dad and are i are working on (sr20de datsun 1200 ute and a 1966 mustang gt coupe), we've found reliable and very experienced people who have previously been in the same position as us and have offered some very solid advice. I'd greatly appreciate it if anyone out there who has done similar work to their sprinter could offer me some good information, or pass me on to the people they've spoken to etc...
I am not in the position where i can spend endless hours modying, cutting and welding just to get the parts to fit, but any information you have would be greatly appreciated.
Thanks.

to start, look at the 4AGTE tech article the WITZL posted about recently..
second, if you have the money and the skills, then stop stuffing about with forums  and go to the source! go and have a chat to Garret abotu what turbo they recommend.. it totally depends on what rpm range and what boost you are looking for... 10psi turbo is very different spec to 50psi turbo.
intercoolers... if you have the money, just decide where it needs to go, how much space is there, make a cardboard mockup of the space, and then take that to a good custom IC mob and get one made... don't stuff around with modifying old crap.
ECU? whatever you like depends what features you like, if you can tune it yourself etc.. if you are stuck with having someone tune it for you, then find a good tuner nearby and go from there. if you can do it yourself, then start at the top, ie MoTec, and work your way down, weeding out features, until you find something you can afford.... seriously....
it will not be road legal with an aftermarket ECU, unless you can pass emissions.

so then just work out exactly what you need, measure it up, maybe make mock-ups, then get it professionally made. easy. more dollars but less hassle

Seeing you have lots of money and no time here are my suggestions:
Buy everything you can for your car from the HKS ( or other Japanese tuning/parts company ) catalog. Have it sent here and just bolt it all on.
TU DAH!!!
Kick ass sprinter.
But then again, you mentioned you don't have any time so you will have to get a workshop to fit it all. But thats cool.....Cause you can afford it 
Honestly, did you put much thought into that question before you wrote it?
You didn't mention once what the purpose of the car would be? Nor what sort of power you are aiming for?
Sorry man but what sort of response did you expect from " I've got plenty of money and no time, whats parts are good for my car? "

sorry people, i dont think i did post my question properly and you have seemed to misunderstand me.
I don't have unlimited money to spend, i meant that i have enough money to actually get the job done properly with DECENT parts, not expensive brand name / custom parts. I'm looking along the lines of turbo's and intercoolers from other cars. Also, ill be doing all the work except tuning the ecu and manufacturing the plumbing/exhaust/ex. manifold myself.
And with respect to time, I meant that i have the time to do the job properly, but not the sort of time i know people put into these projects when it involves some serious modification. I dont want to make the job unecessiraly difficult, otherwise i would have gone for an sr20 or something similar, and i chose the 4agze for simplicity (as does everyone else). The sprinter is my only car, and i am studying at uni, so the conversion will have to be done in the span of maybe a month or so over a holiday.
The main aim of my post of just to equip myself with some decent information so i could get the best results for a good cheap price.
BTW, the power output i am hoping for is somewhere around 180hp - 190hp at the wheels, which i have heard is not too unreasonable. Although, the main aim of my ecu tuning will be drivability.
Sorry for the wording of my first post, and please forgive me, i'm new to forums and didnt realise how specific i had to be. Don't think i'm one of those people with endless money to waste, because Im definately NOT. I'm also not the sort of person to leave everything in the hands of a "professional" who'll be wanting to sell their own parts to me, but i am willing to invest the right amount of money to do the job well.
Sorry all, and thanks for correcting me.

That power target is definately reasonable. take a look at http://forums.toymods.org.au/index.php?t=msg&t h=26848&rid=218&S=7006a4c07f22d13d58b1da76 58f07089&pl_view=&start=0#msg_231835msg_23 1835 There have been very few 4AGTE setups at Toymods Dyno days that made any less than 180HP at the wheels, remember our dyno day results are in Kilowatts. The only 4AGTE I can think of that made signifcantly less than your power aim was actually running a TO4.
All of the good performers that I've seen have run Garret turbos (T28BB off a S14a or S15 would suit your requirements and have the ability to push significantly more power than your aim) and decent custom intercoolers. I don't think you'll find a intercooler off another car that will both fit well and do a good job of cooling the charge, possibly an EVO or import VR4 cooler with some tank mods would suit.
Have fun but I think you'll need to budget a lot more time than you have so far.
