Gtti in itsorignal design can not perform like this.it got only normal turbo which works on exhaust flow...one have to install NOS(very harm ful to such small engines in the long run), the main problem will be to fix the brakes at such level to control the car(Brake booster wil require upgrade also)
Kissa is a charade name with 1.3 litre engine(1987---1994) with same engine mounting set up.
Nos+turbo set up will cost you approx. around 65K
and the initial pick up in that case will be much high than that you expect. because of front wheel drive and less waight.
Charade parts(body) are readilly available at peshawar .
and now a days there is shortage n used engines of charade every where,
if you require any information ...i will try my best to help you...further i wana inquire about your G11 body condition ..because in G11 there is very little space in the hood to suport all such modifications..while in the next shape the engine compartment is big...also G11 front suspension is supported by helper rods. which is very difficult to manage with a bigger BHP engine inside the hood.
