Grigllet has done a turbo conversion on the 1.4 bv mpi b4 and so has sum1 else from scotland not worth it at all, very unreliable and not cost effective, if you want best power increase per £ get a c20xe £1500 150-156 bhp as standard.
U2U lee mitchell if you wana know more....

christ where to start:
traditional tuning route:
Head work
Cams
Exhaust manifold
Exhaust system
Air box (these inc velos tourqe tube, manzal power box etc)
Then u got Throttal Bodies:
SBD are best, but most expensive
Then u got Turbo route:
Expensive for the power u get back, not to reliable tho esp. from courtney as they charge £3000 for it and use 3 single head gaskets instead of a tripple head gasket
Or some people have converted their engine them selfs into a turbo lump
Engine Transplant:
Most cost effective, good bhp and tourqe
Typical conversions are the 2.0 16v engine, and a few do the 2.0 Turbo engine
for a 2.0 16v ur looking at £1500 all in
2.0 Turbo alittle more, about £2000 maybe more
Lee Mitchell in kent does them, so does Beardy in Manchester
Then u got NOS, depending on ur engine size determins how much u can safley put through at a time without internal strengthening
1.6 16v = 50bhp
1.4 16v = 30-35 bhp
1.2 = 25bhp
u can allways use a progressive NOS controller to lessen the damaging effects NOS has
It all depends on how much money u wanna spend, and/or what engine u got

I wouldn't say SBD are the best.
Tb's on 8v's aint worth the it.
£1500 for a c20xe conversion?! Thats expensive. You can buy an Astra Gte 16v for £400 and use the engine/brakes etc, and sell nearly enough other stuff to get your money back.
If an Xe coversion is £1500, a Let conversion will be alot more than £2k.

SBD's aren't the best as u have to wait for ur car to warm up before they will perform, cos if u drive with engine cold, engine will cut out until warm. ur better off going for something like webber etc.
c20let conversion is 3k+

You could always super charge it! There's a place near me that's rumoured to be doing the first one in Europe!

Standard LET engine is 204bhp. If they are looked after and fitted properly there should be no reliability issues.

yer oviously it will be cheaper than 1500 if u done it ur self, but how many people can actualy do that, not many
1500 i reckon is a fair price, 500 engine,loom,ecu,brakes - 500 pvd fitting kit, 500 labour
as for c20let, beardy charges about 2.5k
yer c20let is 204bhp

I'll do 2 days (max) labour for £500!
The LET not only costs over twice as much as the xe but is harder to fit.
Most people could easily do it themselves, its just having the confidence/resources to do get it done.
I changed my engine in 2 days with a mate, there is nothing tricky to it. Once you've seen it done, you hate yourself for paying £500!?!?! for it to be done.
