whats needed?
I havent been on Mig in years and im out of touch. Many 400bhp ones about without n20?
I know Mr Barnes has beaten that. Not sure what he was using at 400bhp?

Must be:
Low comp pistons
Steel rods + ARP's
Tubular exhaust manifold
Decent FMIC
T34 turbo or similar?
Not sure on management though or how far the monotronic can go.
Pretty sure nic's was at 450bhp on monotronic still with the standard inlet?
Hope this helps mate

Think there was a 500BHP LET in this months or last months total vauxhall, unsure 100% if it was N20 though.

The mapping, its all in the mapping.
But as said, manifold and turbo are bye bye straight away.
Pistons, rods, not sure a new cranks needed.
tbh, the cheapest was is a Phase 3/3.5, then slap 100+bhp of nitrous on it.
But tbh, if your going for this kind of build, start off with a £200 XE, drill the oilways (not something u'd do), and save yourself buying a £1k engine to strip down.
It would need a manifold, new turbo, new IC, new pistons and such anyway, so no point starting with a LET.

id personally say the following
low comp pistons of your choice, i like wossner ones
steel rods even some of the ebay ones are ok
some kind of 200sx manifold is nice
id prefer to have under piston cooling
std head
std inlet
std tb
different top hat. i had a regal enlarged one worked fine
3" turbo back exhaust
decent size intercooler
550cc injectors dont really need bigger
weber fpr from a cossie ideally or fancier one if you want anything but fse
one of those walbro fuel pumps
better spark plugs gapped at 0.6 i like to have
its ok on 52mil boost pipes but better off on bigger ones.
turbo wise get a gt30 copy for a couple hundred. wouldnt be amazing but would make the power.
you can run it on motronic. i ran mine on phase 4 ecu it was ok. be better off mapped properly however.
probably more ive forgotten, but id bet vxr will fill in the blanks.

oh my other top tip for the day is a bailey dump valve is shit when needing to run some bhp. it cant get the air out at all, hence probably one of the reasons my turbo snapped its shaft i reckon.

Nice one dude.
Just out of interest why use the regal tophat and not a bigger one?

Thats cool, did you have any leaks from yours? I seem to remember some massive drama on MIG about them not being flush and creating mild boost leaks....
I had one for the Calibra but never used it!
Also Motronic = std corsa Ecu + eds/vmax chips yeah?
Whats the alternative.

yeah motronic is the std ecu from the engine, just had eds phase 4 chips in it. they were programmed to run with the 550cc injectors aswell.
aftermarket stuff is far better. omex, dta, emerald, mbe etc. theyre all very similar.
and no, didnt have any issues with the top hat at all.

i mean in all honesty jambon, id do it all the costly way really. none of this phase 3,5 and nos like vxr is suggesting.

Id be keen to fit a NOS system not for the bhp, but for the anti-DET safety measure 
If i did it again, it would not be anything other than the "proper" non-cost cutting way.

its not as such custom, its aftermarket. its mapped to suit the engine itself and the mods it has instead of being some generic map on a chip that was made on a car that isnt yours. its never going to be ideal. plus with aftermarket, you can bin stuff like the afm and other useless stuff.
