whats every ones preference turbos or superchargers, i put it down to what engine and what you want out of it

[CortinaD]

I went turbo because I could at the time, maintain a relatively stock underhood appearance. Had nothing to do with power or how it puts its power down at the time.

[XMAN]

turbo is better

This is a huge topic which comes down to personal preference in the end.

A lot depends on whether you fancy your abilities with making brackets, pulleys and belts to get a supercharger in on the side of your engine versus welding up some steam pipes into a manifold to fit the turbo on the exhaust side of the engine.

I would say it is much easier to graft a turbo on.

The rest is much the same, you are going to need:

good control over fuel and ignition systems
programmable efi would be the best way to go there
lower compression
cam to suit
well prepared bottom end
intercooler and piping will be a good idea either way.
decent exhaust something like 3" or bigger

Generally a supercharger is considered to be more responsive down low in the revs but in a lot of cases this just ends up giving you huige traction problems anyway.  A well designed turbo system can provide a fairly progressive onset of power that makes a very drivable package, just look at the BA XR6 falcons.

I prefer a supercharger, i'm not keen on the extra underbonnet heat associated with turbos, the hassles of extra piping in an already packed engine bay etc.

Heres a pick of mine, its an eaton M122 with a water to air intercooler.

[MarkZE]

I don't think "underbonnet heat is a worry for you with that thing.  Looks like it will be mostly outside the bonnet.  I love it!

Is that whole manifold setup with intercooler etc designed to bolt directly onto the 4L Lexus or do you still have to make an adapter of some sort?

[Bucster]

Lol, yes it does sit up a lil bit.
The manifold had the original runners milled off it and the 1uzfe runners welded on. Now it needs the starter motor repositioned somewhere cause the air/water intercooler sits in the valley normally where the starter motor is.

Sweet.  Surely someone makes a bellhousing to run a C4 or something behind them which would have a starter motor out the normal side position?  I will be interested to see what you find.  I assume you are going to stick with the Toyota 4 speed?

A mate of mine just had an A340 Toyota box built with a high stall etc to run behind his turbo 2J engine.  Mike at MV autos in adelaide did it up for him.  He seems to be a guru for the Toyota boxes.  He does a spragless second gear and transbrake for them now if you want to go for big power.

The one he built for the 2J cost around $2800 with a modified converter and shift kitted valve body etc.  He also had the issue with the rear output shaft he had to saqwp to the yoke style one when having the box built as he has grafted the 2J into a 1989 7 series BMW.
