hello all,
ive currently got a 1.2i CORSA,
but in the next week or two ill will be dropping a GSI in it.
what i was wondering was, what would be the bets mods to do to get bhp gains and also, what are there prices?
ive been told that first thing i should do is to get a viper induction kit on it.........and seconly maybe a de-cat exhaust and then get it chipped!
is this the best order to do things??
if not, which way/order should i go?? and how much each thing going to cost?
thanks in advance for the help!

Depends, the older c16xe's seem to respond better than the slightly newer ones to the lexmaul/velos inlets. Will be a big noticable difference.
I wouldn't go for the cams tho, probably the inlet, unichip, exhasut manifold then some strengthening (apr conrods etc) then cam it, actually bin the inlet get some TB's (will cost about £2k tho  )

inlet - 15-25bhp
unichip - depends on engine mods you ave done... anything from 0bhp to ???bhp
exhaust fanimold - 1-4+bhp depending on other mods...
you cant just bolt something on & expect what the manufacturer says, its a case of mixing & matching components to get the best results...

well broster from here is running 138bhp from his X16XE
Cams
Lexmaul Inlet
Head Polished & Ported
Full exhaust system with Decat
Exhaust manifold (unsure on branching)
unichip...
he said he gets much better results with the cold-air feed removed...

Why not put an XE in it. 150bhp as standard and cheaper than trying to tune the 1.6 to that sort of power!

* Change the inletmanifold
- Mantzel Powerbox
- Dbillas flowtec
- Lexmail RAM
* Change the cams?
- dbillas
- lexmaul
- kentcams
- dr shrick
- etc
* Change the airfilter
- GREEN Twister
- Pipercross viper inductionkit
- or just a K&N or other filter
* Change the exhaust manifold
- supersprint 421
- lexmaul 421
i would not go for a 4-1 manifold..
* Change the exhaust
- Completely supersprint
- Or any other brand
* Change the feulpressure
- Powerboostvalve
- Fuel presure regulator
- bigger injectors
* Remap the ECU
- extend revlimit
- change mixture
I'd recommend this as the final step! It costs a fortune to remap the ECU at each little change u do to the engine
