I have owned many a 306 over the years, soon to be 20 in fact. I have always loved the package factor of the GTI6, superb handling, braking and enough power to satisfy my needs when i want to go for a quick blast round the country roads. For years i've always fancied a turbo'd 6, my engine needs approx another 2k to see it fitted and running for about 300 bhp, however where i normally drive the car i think that level of power and the turbo style torque delivery would spoil the driving experience, so now i'm trying to come up with a relatively fuss free and reliable engine build that will give me a decent increase in grunt yet not make car an uncontrollable animal. Supercharging is the most obvious choice here, i have never been in or driven a rotrexed 6 but as LB conversion mirrors the standard engine's power delivery i can plainly see why their so popular.

So, do i keep and finish off my 16v turbo, go s/c or cams and bodies - something which i'm very keen to try
Car in question has properly uprated suspension and brakes now i just want a little extra power

2k to have turbo
3k for second hand supercharger kit, if one ever comes up for sale
1300 for 200bhp PT81,pockets and map
2200 for cams and bodies ~ 220 bhp

Any opinions be it good or bad welcome

i am tempted to finish it but although a turbo would be great, i don't want a car that can't be driven. N/A's are so predictable whereas a turbo may end up going severly pete tong half way round a fast corner when it comes onto full boost or if you hit a dip in the road and the front end loses traction

i have been in a fair few 16v turbo'd 205/306's and yes they are ballisticly fast but only really useable in a straight line or on the track. Its too easy to get caught up with big bhp figures on paper but for me its how does the car actually drive on the road? whats the point having a superb handling car if you can't use it because your feathering the throttle and fighting immense torque/understeer?

Curveball......

Id finish it now, but i wouldn't have gone for a turbo'd 306 in the first place.

I had a supercharger and it was really good. Very undramatic though, it was like standard but the speedo moved faster.

NA tuning IMHO is a waste of money. The £/bhp ratio is really poor.

This leaves turbo or supercharger. Turbos have potential, but I cannot recall a turbo conversion that has been cheap and/or reliable. They all seem to turn into money pits.

The supercharger conversion works and is pretty reliable and guarantees 230-260bhp. In 30,000 hard miles the only issue that I had was a bearing failing on my aux belt tensioner. Also, given that you are handy with spanners, you''d do a supercharger conversion in a couple of days, if the kit was second hand. I also think that you would probably pay a bit less for the kit. I sold mine for £2,200 (with standard bits in exchange).

+1 to what smegal says

iv replaced a few belts and pulley bearings over the years

although now that my car is high boost is a bit more dramatic, my uprated clutch isnt soo hand for daily driving

naah, its the choice of turbo and cams, but mapping certainly makes a difference.

If it were me, i'd have a good engine with throttle bodies, the noise alone would do it for me!
