3T-GZE Vs 3T-GTEU

just looking for some info on this fellas
theres a good chance im becoming nostaligic and keeping the ta22 for a bit longer so another engine modification mayt be in order
Now having seen a few 3tgteu's in ta22's and seen what they go like - i was wondering what a hybrid 3tgze would go like - aka 4sfed but stroked as well
Im not totally up to speed with EFI, turbo and supercharging so any ideas on performance would be appreciated -
Ie i believe suprerchargings better if you want a torquey motor , whereas turbo means higher top speeds, accelleration etc ??
Also has anyone here Stroked a 2tgeu with a set of 3t pistons/cranks/overbore before - and what was required to do so
If i chose the supercharging option - id find a 2tgeu and build it up from there.
Also would both conversions fall under the $4000 mark , not including diff swap , and would i need a W50 or similar setup behind the hybrid 3tgze

Another thought - would it just be easier to buy a car that already has a 3tgteu modification in it and work from there??

hmm interesting ideas, but chances are if it hasn't been done then it ain't worth doing.
firstly, haven't done anything like it so i don't know from experience, but i believe that it is VERY difficult to supercharge and turbocharge (twincharge) because of piping and pressure issues etc.
stroking a 2TG would be more difficult than using a 3T block and whacking a 2TG head onto it (quite common), still gives you 1800cc, then you could always bore and stroke with an 18RG crank etc (giving 2L), but this is considered not a great move because of reducing revability (could even go to 2.2L with a 3Y crank, but thats just crazy). Theres not much involved with the 3T/2TG hybrid, just cam bearing changes, new pistons (or flycut old ones), a bit of mucking around with them.
A mate has done the worked 3T/2TG hybrid engine, bored, cams etc, cost him so far over three grand because he had to get everything top notch and re-worked otherwise it would be unreliable (whats the point of working an engine if you can't rev it passed 8000rpm  )
W series gearbox strongly advisable for any more horsepower than over stock 2TG power (around 130hp, but heard T50s have taken a lot more). W55/57/58 the goer.
The last option would be the best. Considering you have a TA22, any engine above 1600cc would need engineering/inspection for registration, especially a 3TGTE (brake, seatbelt upgrades, inspections etc) . Best option would be to buy an already converted/engineered/registered TA22 with a 3TGTE sitting in it.
Once you go turbo you can do upgrades for horsepower increases, where as working an engine to the max eventually comes to a dead end, and you can't get another power fix.
This is just my opinion, mainly goss i've heard or read, hope it helps ya.

Re twin charging this wasnt my idea - i guess i didnt make it clear - Idea was a supercharger OR a turbo charger
tim frosts celica 4sfed had a supercharged 2tgeu - my idea would be using his engine idea as a basis - then stroke it , though in that case i would be stuck with a t50
the other gives me the stronger box and probably a better basis - though superchargings an interesting idea since not many do it ..
Anyway id look into it in detail before hand .. I could probably pick up a converted Ta or RA with a 3tgteu setup already done for 4-5 grand then build on that ..

I'm not a big fan of supercharger setups, because they're often more expensive than a turbo setup (and definitely more expensive if you're starting with a turbo engine), and they're also much less flexible if you want to do mods in future. A well thought-out turbo setup will still have excellent mid-range performance and an acceptable bottom end to go with the screaming top end - the supercharger would only have a significant advantage at very low rpm, which is exactly where you shouldn't be in a T series engine anyway! 
And at the end of the day, a turbocharged engine is going to make more power than a supercharged engine, all else being equal. Turbo gets my vote for certain!
If you want to stroke the 2T-GEU, it's a piece of piss if you have a 3T donor engine - just swap the bits over. As for using an 18R-G crank as someone suggested, that's totally not going to happen - R series cranks are not at all compatible with T series blocks!

Ta norbie - All this info is much appreciated BTW - as i still dont really know what i want to do with my ta22 ..
in a fortnights time we have a dyno day coming up so ill eb able to guage what my ex drag 2tB is doing - For all i know camming that and stroking it out further might be a fun option - but by the sounds of it for money wise - id be on the smart cards to buy a already converted 3tgteu and build around the already installed and engineered motor. Means 2 celicas in the shed though - one old school Carbs and cams ) - one new school ( EFI and turbo )
Ill have to ponder this
While im at it - anyone know of say an ra28 thats already had a 3tgteu converted ?? Id like one of those motors int hat shape - though i hear weight wise its so much more fun in a ta22
