What turbo would be a good upgrade for a uk classic. Believe that the standard one is on at the min and am interested in upgrading. Have heard that if u put a bigger turbo on then acceleration would be reduced or more lag but better mid range, Is this true can some1 reccomend a turbo that would give me more acceleration. Octane booster, what does this actually do and is it worth it?

Octane Boost raises the RON of your fuel which in turn reduces the chances of pre-ignition when driving hard or running high boost.

The standard stuff from NOS (£10) can increase RON by up to 3 points but they also do a racing only version (£20) that can raise RON by up to 6 points.

I have tried both, the first for normal road driving and the second for a track day.
The stuff seems to make the car feel a little bit more potent on hard acceleration but not much else and it didnt seem to do any harm. I wouldn't bother with it for every day use in a standard or mildly modded car if you use Optimax (97 RON) or equivelant.


Havn't got a clue about the turbo's, there's too many to pick from.

depends what turbo you've got. Best one for less than £200 would be a TD05FE. Otherwise you're looking toward the thousand quid mark for 400bhp capable ones.
