**lambrover** · 25th January 2009, 08:39 PM

has anyone done it or no anything about it, I have been playing with the idea of doing one or the other, for the carby 3.5 v8's out there what upgrades have you made that make a difference. cheers

my choice would be supercharged. but if your going to all that trouble with the 3.5 ide do a complete engine swap,,, still something alloy and injected...LS7

cheers phil

ha mate i just been looking at the latest for your car (members rides), been busy. I am mainly interested in doing it for the experiance and it woud be cheaper than that type of engine conversion and the v8 will come out in a couple of years for a diesel so i'll have a play with what i got now.

Both have been done before, i would love to see a turbo'd one though!
Other option if you can't deside, go both

We had Turbos for the 3.5 in the 1980s in fact I remember walking past it sitting on the workshop floor daily thinking about it,
We were in Alice at the time and wouldnt fit it because of the heat.
The purist would run a Supercharger but today you can get more go for less money with other engines.

I entertained the thought of twin turbs on a V6 Commodore, until I realised that the price of the manifolds and turbos exceeded the net worth of all but the newest of Commodores

i would go for a supercharger. should be easier to set up the carby than a turbo. the boost on a supercharger is more of a constant so it will make the jeting easier, with a turbo the boost is all over the place and you have the problems of turbo lag to contend with. if you do want to go turbo you need to use an after market efi system.

thanks guys, I think supercharged would be easyer to as mounting and don't have to change the exhaust manifold. well I need to keep my eye out for a supercharger now and a blow through carby c what happens.

Twin turbo would be the go, don't boost it over 7 psi on stock internals. Do a blow thru set up with a boost ref fuel reg then you just need two oil lines, exhaust manifolds if you can't flip the std manifoild.

Turbos are softer on pistions, rods and cranks then superchargers. if you get the right size turbos it would be on boost from about 1200- 1500 rpm. Last car i put a turbo (sierra) on cost me $100 to make the exhaust manifoild 200 for the turbo and $150 for the pipe work to the carby.

I want to do this to my rover after the move if i still have it. I think i could get it running for under $1000 with the turbos. I will do a write up if i keep the car and if there is enought intrest i'll make some extra manifolds up.
