Even with a second hand 3.2 GTA engine swap and power via induction/exhaust and chip to an uprated 300 BHP, you are going to struggle to get a sub 14 second time... That will be the real limit of cost.

Then there is also the big bore route of 3.6 ltr (350 bhp'ish)
Or turbo /supercharge kit but that is very expensive indeed. Not much change from £7,000 to do the job reliably

The cheapest way to get a sub 13 second car using second hand bits to keep the cost within your budget is this:

Even a modded 3.2 will only make 275bhp, some of the 3.8 conversions on here are still short of 300bhp.

Best bet in my opinion would be to spend 500 on a decent exhaust, get a better filter/airbox, make sure your suspension is in tip top shape and then spend the remainder on having a good quality nitrous kit fitted.

Should be able to use 340bhp safely for short bursts

GTV V6

As a rough guide using this Link you would need about 335bhp

I think the only way to do this without spending a fortune (from what I have read on here) is to fit a rotrex supercharger. You could keep an eye out for one going second hand, if you go to their website you can find out which model fits the GTV so you could keep an eye out of one on Ebay and fabricate the mounts, ducting etc yourself. If you're patient / lucky you could mayvbe get it done for sub £1k

This will put a fair bit of strain on your engine though so youd probably want to use the rest of your budget getting the engine serviced and up to scratch

Traction is your problem - first question; do you have a Q2 or Quaife limited slip diff?

If not, this is the first thing you should do.

Second - what front tyres are you using? You need the absolute best money can buy, for ultimate straight line grip. Judging from your avatar you're running 16" wheels, do you have a 5-speed or 6-speed box? Lightweight 17" wheels with 225/45 tyres would be better than your current 16" wheels with 205/50 tyres. A 6-speed box would also be preferential for the slightly lower ratios - lower ratios means more torque at the wheels.

Its not all about the engine & power - you need to be able to put it down to the tarmac to accelerate the car rather than just spin the wheels and thats what FWD doesn't do very well.

With the budget you suggest, diff some suspension work, lighten a bit, but nos will be your only bet. There is one member who has got good times using nos on 2.5v6 I think. Personally wouldn't bother.
