Basically the 2.0XE has one throttle butterfly which lets air into the inlet manifold, this air is then split between the 4 cylinders.
Throttle bodies have 4 throttle butterflies - one for each cyliner which means each cylinder gets much more air.
Air + fuel = Power
Difficult to compare them to a turbo as they are a very different way of tuning. There are loads of advantages of each.
The main advantages of throttle bodies are that the power delivery is smooth all the way through the rev range unlike a turbo where power is delivered when the turbo spools (usually around 3k revs)

I loved my old throttle bodied xe'd Corsa, was great fun............
And another big advantage of throttle bodies is the noise!!!! MMMMmmmmmm! Even compared to 320bhp of Subaru boxer 4 it sounded great!

yeh but its all about the drivability and delivery.... haven said that i wouldnt say no to either.. i always though ya would have to have a massive spec to get a let to 280... but have been reading up on phase 2 lately... how simple

phase 2 is what i want,
to buy an let, rebuild, fmic, phase 2 is about 2.5k,
210 bhp throttle body needs heaps of internals and will be 2.5k - 3.5k at a guess

Trouble with a turbo on a front wheel drive is getting the power down, once you get it down then yeah, with 280bhp your bound to beat a car with 200bhp.
Like people have said though, its all about drivability. I would much rather have throttle bodies than a turbo on a light front wheel drive. Not only that, throttle bodies are very simple, so there isnt much to go wrong with them!

yeh im not disputing that,
but for power per £££ then the turbo in my scenario wins!
My engine has had a full rebuild, just needs headwork and better pistons really to be able to run tb's!
Plus i can get a really good deal on omex ignition
im confused

The only internal work on an xe to get 210bhp you need are big end bolts. I used Cosworth but ARP do them as well. The only reason you need them is for the 8,000rpm limit.
Full throttle body kit is £2000 with management. That will take a good 155bhp xe to 190ish, add to that a manifold, big end bolts, a 2.25" zorst, cams, trumpets and a gas flowed head and you would easily see 210bhp!
I just dont think the LET is the way forward in a corsa, but to be honest I dont think a 2 litre engine and box is full stop. I reckon a 1.6xe on throttle bodies with about 150bhp is a good balance!

Without doubt! Turbo charged engines are a doddle to tune, but you wouldnt need more then 200bhp in a corsa anyway!
Balance and drivability are far more important than outright power!

i dunno what to do at the mo... chuck the 1.6 for a 2.0 or what.... i have omex managment here for it but i do feel the engine needs a good freshen up before it would be able for some Tb's... i suppose form 1500 quid i could have tb's and a rebuild... but sfor the same price i could have a 2.0.... i have to bar in mind that the car is a daily driver...

Tough one that! Cos realistically a standard 2.0 is gonna be a lot more reliable than a throttle bodied 1.6 and you dont have the cold start headaches and the noise!
Daily driver Id probably say a standard xe! I think? Maybe?
