Have a good hunt around the shoptalkforums, here http://www.shoptalkforums.com/viewfo...8291899422a8e5

Probably loads of answers to your questions.

Are you thinking carby turbo or EFI?

And also lots of interesting info here http://lowbugget.com/1600t.html
and check out http://www.dune-buggy.com/turbo/enginebasics.htm

Good luck

carby, i think i will get a weber 40 for the job, and i just heared that the draw-through type is more reliable in our engines(carberated aircooled), just need an electric pump(i will get it from any car)...
but i have a very important question, i think we should all know before adding a forced induction system to our weak aluminium engine, what is our boost limit that the engine could handle, i guess not much, my engine's compression ratio for example is 7.30:1 (1300cc, F) when in good condition, so how much the safe ration i could add to it with the turbo????????
deos anybody know????????
thank's man for replying...

If you plan on doing a carburated turbo motor go for the blow through. It might cost a bit more (modify the carbs), but i believe its a lot safer and more effective, since you dont have the air/fuel mixture going into the turbo which gets extremely hot...

Personally for my next motor im planning on big cc's and a turbo with efi...

u r right man, i heared too that the blow-through is more efective, but why is the most aircooled engines contains a draw-through turbos???, and if u suggest a blow, is it safe to my engine and what mod in the carb. i should do(details plz), plz tell me what to do, cuz i need a safe install for a daily rider and a as i said before that i want this to be as a project, i mean more power with resonable mpg for daily riding...plz guys i need ur help as i should ask u experts here...
god bless,
thank's...

keep it simple and do a drawthough. if u want the benefits of blow through, go all the way and do EFI.

carb modifications are : different gaskets and different o-rings at the butterfly shafts in order to handle the pressure. appart from that you should get some bigger jets for your carbs to match the required fuel levels when under boost (otherwise your engine will run lean and start detonating...).

if i remeber correctly the carb turbo kit is available from cb performance.

Also look for a small turbo (small>nil lag thus better drivability for a daily driver) with an integrated wastegate (most OEM applications> easier to find and cheaper) and a seperate blow-off valve (that will protect your carbs and your engine from excecive boost pressures)
