ok... i was wondering...
I have a 93 4.3l vortec engine. ive searched and searched for turbo kits and have found nothing. Would i be able to put 96-up vortec heads on my 93. If so, wound this allow me to use a turbo charger that was made for a 96-up on my 93. :naughty:

going back to the origional question. I was wondering if the head change would give me the option to turbo charge without having to make custom manifolds.

go to autozone.com and look up your part and the part you want and see if it is the same part number

alright. ive found lots for the 96-up but nothign for my year. Intake, computer, turbo, superchargers, cams, headers, lots... But the only thing ive been able to find for mine is a cam but it was 400 bucks.

If you don't even know what your engine is, you shouldn't be turbocharging this engine.

I would go on ebay and get a big 16b and bigger injectors then have a exaust mani made then route the pipes to the intake and don't go over 8psi it can be done but I would say sell that truck and get something that came turbo. it will be a huge pain to turbo a non turbo like yours cause it has really high compresion.
