Ok - looking at 'tinkering' with a stock (car) engine for the first time ever. Have done motorbikes in the past though. Used then SEP at Kegworth and they have given a price of 300+vat to gas flow the head.

So what can specifically be done to this engine to increase the BHP and performance?

Recommendations for other established professional 'tuning services' also sought.

www.migweb.co.uk would be your best place to ask, it's a fairly big specific vauxhall forum. being a naturally aspirated engine any big increases are going to cost big money, options to consider could be fitting one of the vauxhall 2 litre turbo engines or selling it and buying one that is quicker from stock.

My stock answer for anybody that wants more performance from any vehicle.

In order,

1 Sort the brakes
2 Suspension
3 Brakes
4 Tyres
5 Brakes
and then finally look at the engine.

Sounds odd, but think about it? If the brakes are that good you can approach any hazard faster, and if the tyres and handling are up to it it will corner faster!

Cars can be made equally fast in a straight line; its getting round the corners better that makes a care perform better!

In the words of an old road rally master, "most people use their brakes far too much and have to rely on their engine to get them back up to speed. If you can rely on your brakes and only use them when really needed then you will drive much faster!"

Not that am I supporting driving faster on roads btw, but its the same principals for track too !
