idiots guide to supercharging..

[the scotsman]

Thinking about putting a supercharger on my mk2, looking for any help guidance etc about what to look for and a rough guide of the costds involved. Engine is 2ltr with polished/ported head, fast road cam, matched manifolds... advise away!

i dont know much about it either, i know the principle of how it works so i wanted one on my car. The lowest quote i got was $12k!! So my car remains stock

expect it to be as expensive as turbo-ing.

I think you'd need a de-comp plate, to lower compression a bit. all the pipe work, the supercharger, and depending on whether you're digi or Kjet engine manage ment, will need adjusting I thnk. Figure you'll need a new cam to get the most of of it. and then tuning, the whole engine would need retuning with the SC on it.

I thnik i'd be simpler to do a 20VT conversion in it, in terms of value for money and ease of conversion and end result (more powah!), that is unless you know of any supercharger "kits" for them.

But yea,. I'm no mechanic. that's just a few things that came to mind, I'm happy to be corrected on anyting.

im looking at doing the same. i think a toyota s/c would be best. if you are using the factory computer you may have problems tuning, but you will need to lower compression, run an adjustable fuel pressure regulator, bigger injectors, possibly a bigger fuel pump. there was a guy on here with this done to his 2L, but i havent heard from him

Just a little info on the toyota ones, ull be after the SC14 which came from the 1GGZE motor. They have a clutch on them so you need to hook up a switch to turn the s/c on much like u do with ac. I would say u need aftermarket management, i wouldnt go playing around with the kjet stuff (but i dont know much about it anyway).

you cant compare a bolt on supercharger kit to a 20VT conversion its a whole diffrent ballpark

i wasn't aware there are any "bolt on" kits availiable. any SC setup would have to be custom wouldn't it?

[WABIT]

bolt on meaning stock internals and no engine work done.... just fabricate and tune is classified as bolt on

[Jarred]

From my orig quote thingy, I was talking about a bolt on kit, well thats what I meant. ie a kit with all the piping and upgrade hardware etc that just bolts on, and fits, ie no custom work.


As far as i know there arn't any kits that just bolt on/bolt into place. That's probably what I should have said in the first place.

ah-ha! I know know of a "bolt on type kit" well actually, I didn't really read it in great depth,but have a look at this mate:
