hi,

my 72 240z motor already need a rest. so i started looking for a motor. I find one from an 82 280zx turbo. the guy is selling it for

$150 including the turbo. my question is - is there any way i can use that turbo on a carburated car and is it possible to use the turbo boost (switch on) manually. if i am being funny please let me know.

$150 for a complete, good L28ET is a bargain. This is a simple reply, but your best bet is to rebuild the L28ET & stick it in your 240Z with the factory ECU & really 'enjoy the ride'.

A turbo requires exhaust gas to function (and lots of it) so there isn't really a way of turning a turbo 'off'. But if you don't press the loud pedal too hard, you won't 'use' the extra power that the engine can produce.

Every car I've owned has received a turbo kit. It is efficient, cheap(cheaper than the same power output in a NA motor), reliable & good fun.

I was getting the same fuel consumption from my '73 240Z with the EFI & turbo kit as I was getting with the twin carbs. RWHP was DOUBLE & RW torque was TRIPLE that of the standard motor.

I run a 'milder' setup in my Skyline with an L28 & the RWHP is still double the factory L24E. I have more RWHP at 3000rpm (~50km/h in 2nd) with the L28ET than I had peak output with the factory L24E (~62kW). I also get ~12L/100 km fuel consumption (better than the L24E), partially as the extra power has allowed me to run a 3.54 diff, up from the standard 3.90.

I can still do the 0-60 in ~6s...

You _can_ make the turbo work with carbs (that's the way it was done with the early turbo kits). But times have changed & you are best advised to use EFI.
