alot less than if you got gmc to fit a turbo.

and you cant use a 4-2-1 with a turbo.

was on the gmc motorsport site and it said the rotrex supercharger for the 16valve gives a 90% increase and if i have done my maths correctly that means a standard vts with 120 will be 228 bhp,it sounds good!
and you cant use a 4-2-1 with a turbo.
oh rite,im learning slowly lol

N/A cams arn't the best for forced induction - cam overlap results in blow through!

with those mods (possibly not with aa n/a manifold if your plannin on actually attaching the turbo to the car :P) you'd be looking roughly 2,500
...pounds sterling to insure the bloody thing ;) i couldnt imagine ringing my insurance company and when they ask "any modifications sir?!" trying to break it softly to them that "yes, ive bolted a dirty great turbo to the side of it!" hahah

I have looked at getting something different for my VTS in the not to distant future, possible a Supercharger, have phoned insurance and they would want about an extra £400 whichi s pretty good tbh, just wondering what i should go for Turbo/Supercharger? and difference in BHP
I heard somewhere that a supercharger would cost around £5000, could i just not take one out of another car like a mini cooper S?
Cheers GUYS!

The super charges most people fit to the saxo only cost around a thousand. Its all the rest of the parts you have to get it up and running that cost the money. So even if you get given a charger it will cost you a lot. If your having to get parts made up for a unusual charger you can end up paying even more because you are talking custom fabrication. You also get the problem with custom that you will often have to get it wrong a few times before it works well. So you can end up spending even more. This is why the GMC charger is generally considered so good as its been fitted to so many cars and some of the cars have had massive miles. Nowadays the kit is bomb proof.
PS, Copper S charger is very small.

problem is both ideas are flawed... superchargers are a pain because no one really knows where to mount a charger and often they are bigger so jigging stuff about to make it fit is an arse.
On the other hand, everyone knows where a turbo goes, and due to the forward manifold design of the saxo, then it slots in there and is natually cooled (a bit) by incoming air etc... manifolds are readily available and on the whole a turbo conversion (in comparison) is fairly cost effective given the gains.
The downside is, the problems... your putting excess strain on an engine that was 90/100bhp from the factory and stretchin another 20bhp out of that in n/a form is hard enough as it is... so forcing another 4-6psi into the cylinders is putting strain on every other internal componant... also remember that whatever you do your going to need to uprate other componants to cope with the added performance of the conversion (brakes etc) so it doesnt just stop at bolting a dirty great blower to your motor and spanking it everywhere!
If it was easy then we'd all be flying around in 200bhp pocket rockets but the reality is that id never dream of turbo'ing my paxo... just on reliability grounds alone. That said, theres nowt better than "that" sound really is there :P
heres to wishing!!

sorry ... let me correct that... people do know where to mount a supercharger... obviously otherwise no one would have a charged VT... what i meant is that mounting one to a motor that was never meant to have one is a c*nt!
sorry to anyone who took that wrong!

Something tells me you don’t really know the TU engine that well Mellor. These little engine have bigger bearings and run higher oil pressure than most 2ltr engines. This is a lot to do with that it was intended as a diesel and petrol so everything is over the top with them. The old DP cars were running .75bar that gave over 190bhp @ the wheels and were a stock engine. My friend has had one for many years. He has had it so long the what was new turbo actually got warn out. People have run stock rods and pistons at 1.4bar though never known any one who has done this for long. There is no reason at all that turbo saxo can not be reliable. The weakest link is the clutch and gearbox. But the gearbox is easy enough to improve but most people just use the larger box found in most PSA cars if there going for much over 200bhp. As for the clutch well that a very easy one to improve on.

as above ive done over 10k miles on my turbo engine (and yes i cained the shit out of it for every mile) and apart from 2 clutches and a manifold to turbo gasket (my fault for running to much boost for the exhaust side of the turbo to cope with) it has never let me down and never once not started, only reason its in bits now is i want silly power, and that was all on the same gearbox with 189lbs/ft and over 2000 hard launches
as for insurance HIC only charge you for going 10bhp over standard even then its not alot, with everything declared and insured for £15k agreed value i only pay £500
