I have thought about SC supercharger kit but the cost is quite high so was leaning towards the turbo route
just need to work out what bore and pistons to use if i go turbo

Paul is gay so ignore his supercharger comments

Hat i did was a mildly tuned 5 port turbo to keep it simple. Makes 130 bhp , and cost next to nothing to build. Im currently building something more power orientated. Once you initially get it up and running you are half way there

what are the cost comparisons between turbo and supercharging
I know SC kit is fairly pricey which is why I was leaning toward the turbo route

theres not a lot of choice for chargers, its either somthing new (ie the SC rotrex) or use an eaton of a bini or merc, and to be honest the eatons are a bit crap,

your probably looking at similar cost to do a turbo or eaton setup,

Is it going to be a road car. Ive heard the cam pawl diffs are horrid

1/4 Mile 14.3secs 96Mph Terminal 10psi of boost.

Imo sell the tb's get a single and get a plenidumdedum made up, exhaust manifold and get a gt turbo, sell the rs cams and get the lt 16v cams (iirc jimster found them better on his setup) and a good intercooler. You could run high or low boost depending on what your going to use it on. If for a road car i would got for the gt17 or a vnt gt20 or 22 for driveability.

Thank for the replys
Its going to be a very fast road/santa pod car/trackday car
I know the diff will be a pain to drive on the road but going to see how i get on with it
good idea about the throttle bodies sell them and go with a single with plenum & intercooler
whats the best single i can get from another car and is it a case of a bespoke plenum or an adaptation from another car
I have seen turbo kits for the k1200rs bike their plenum looks good with water injection on it too

Now here's a question been given the go ahead by the fuhrer to get the car up and running i have about £1200 to get the engine sorted i need ecu and a conversion kit not sure if i can turbo it for that if turbo'd i have rs cams to swap for lt ones and trottle bodies to sell but turbo and plenum to buy then got to sort out manifold ideas gents?

might decide to sell the lsd + 3 different crown wheel and pinions then just go for a x-pin should boost funds a little

£1200 will be eaten up pretty quickly unless you can do the machining yourself

If i decide to sell the diff and crown/pinions can probably go to £1700 for engine up and running I am doing block work, head work so should keep the cost down a bit

I costed around 5k to build a 16v turbo engine and box, that takes into account about 1k for fuel injection stuff.

I suppose you can knock off £500 for an LSD at least!

If you decide to sell the LSD, give me a shout
