ultimate 2T/3T???

just for interests sake at the moment (i've got two project cars i need to get on the road before i can afford to start this) i was looking for opinions on the ultimate 2/3T engine. for boost of course 
i've never built an engine before so once the celica's back on the road i'm going to start picking up the parts i want and start putting something together. i'm not looking for expensive aftermarket parts and i've got a friend who can weld up inlet/exhaust manifolds although i'd prefer to stick to stock parts if they're not too useless.
i'm after opinions on the best block, crank, piston, rings, head gasket, head, fuel rail, inlet manifold, exhaust manifold, turbo (not stupidly insanely huge expensive turbo, something not too harsh for the street but handy for drag racing), and things i should do along the way like match porting and stuff.
i was thinking about just going with a stock 3T turbo engine (twin spark i think?) but i remember seeing someone recommending putting a 2TGTEU head on one, i assume they've got better flow and while i was thinking about that i came up with this idea.
any information appreciated, especially if you've done the work and know the performance gains,
cheers
Matt

stock parts within reason, i don't want to have to buy a super expensive head (although i wouldn't mind learning a bit about port matching and improving flow along the way) or spend a thousand dollars on a turbo. i'd probably be happy to lay out for new pistons, head gasket (are TRD head gaskets worth the extra $?), and rods if i needed to, manifolds i'd prefer to use stock. i just figured with all the combinations available from the different types of 2T and 3T there must be something that goes together to make good hp. doesn't seem like anybody knows exactly what though.
i'd assume that 3T crank and pistons would be best because it'd mean an extra 200cc to play with, are there any benefits to the twin spark plugs on the 3T head. i remember reading somewhere that the later model 2TGEU head has better flow, would this outweight the benefits of twin spark? whats the best amount of compression to use for a turbo and what parts would i want to use to achieve this compression (wouldn't have a clue how to calculate this)?
this is the sort of info i'm after but i didn't want to get too specific because then i'd probably miss the little tricks that people have used along the way,
cheers

grab a 3tgte
use the crank and rods
get a 2tg head number 88261 or 88222
make custom plenum and exhaust manifolds
port match and light porting
custom pistons 88mm which will bring it out to around 1900cc
use the 2tg cams or get a rally grind cam
get a 320-400hp gt25 from some place or get somthing kinda large from the jap wreakers (nothing stock)
should get you 180-200kw

and has a 3tc got the same bottom end? i know someone who's got one spare and if i don't need the pistons or the head and the bottom end is the same i might have to try and acquire it,
cheers
