Outer Limits 4x4 Board

I have a 1996 mazda bravo that i either want to bolt on a turbo or supercharge it i just don't know which way to go. Would the supercharger that castlemain rod shop sells for 6cyl commodores fit because i think that it would be cheaper to supercharge it, has any one on here done this or know somone that has and has anyone got any suggestions as to which way to go.

call castlemain rod shop........

oh shit that did not occur to me... i just thought that somone on here might have done it thats all.

the owner of the is company (Robbie) lives across the road from me he is very professional to deal with and his employees know superchargers and turbo system very very well.

i am currently speaking with him to supercharge my jeep.

bin meaning to ask the same question is it better to supercharge my landcruiser 1hz or turbo it, the stats say u get more power from a super than a turbo

horses for courses. A super sharger delivers torque from idle, but uses power to run. A turbo delivers torque a bit further up the rev range but uses no power to run

that isn't quite true - neither gives you something for nothing - both require power to run. Turbos are lighter, cooler, more efficient overall, require less crankshaft horsepower increase for the same flywheel output power, are usually easier to install, cost less, and are easier to intercool... but superchargers do provide puff right from the word go, and that is important for some applications. On a diesel engine a correctly set up turbocharger system will drive a lot like a supercharger, with next to no lag from idle and boost from very low rpm, without sacrificing top end breathing.

Is the Bravo petrol or diesel? Petrol engines need a fair bit more engineering to get any forced induction system up and running correctly, and this significantly affects the cost.

The bravo is petrol i should have said that i forgot to mention that, i have just put on a arb steel winch bar as well as a winch and that has slowed the 4x4 down a bit i have noticed... there is a sports exhaust going on in a few days so hopefully that will give some power back but i would still like some kind of forced induction.

the smaller suprechargers to suit 4cyl engines usually only produce about 10/12psi of boost (according the specs on CAPA's web site) and require 20% of the power it produces to drive itself, i run 13psi of boost on mine, other T/D's run up to 18psi......... for your requirements (petrol engine), a small turbo would probably work better than a supercharger..... pays to research

superchargers do offer smoother power early in the rev range - also they offer either a constant or exponential boosting, also they do not complicate the exhaust system as a turbo.

from what i understand they are various complications applying a turbo to engines larger than 3.0L and generally better reliability is gained from a supercharger.

turbos are far cheaper ie less than half the cost .

i chose supercharger for smoothness and reliability.

Just thought I would mention that I know a guy who is making over 340rwkw with a turbo landcruisier motor on stock internals. Has also run a 10 second quarter mile in a Toyota Crown.

Nothing wrong with >3L turbo engines. Just means that the boost comes on quicker and you can also run larger turbine A/R’s which will decrease exhaust back pressure and increase power.

I had a Sprintex supercharger on my 2H years ago, then put it on a 1HZ. I have a turbo now (1HDT) and although I miss the massive torque at idle, I much prefer the turbo in terms of simplicity and maintanence (ie none) The Supercharger was always a problem with belts & tensioners, and was noisy all the time.
Having had both, Turbo's the go in my opinion, but that's on a diesel.
